You never really know what might lurk deep down in the depths of a muddy, tropical river…

 

This story is dedicated to my long-time loyal friend and fellow adventurer, Ernie Pierce. Ernie and I did three prospecting trips to Madagascar together, of which this is just one of the stories. He played a very important part on this project in working out how to increase fine gold recovery when processing heavy sands through standard riffles within the sluice box of a suction dredge. Ernie has an enthusiastic, magic disposition for being able to work out solutions to challenging problems in the field. He also overcame the primordial fear that every human being has of going down into deep, black underwater holes (where dangerous monsters lurk, if only in your imagination). I don’t know very many people who are willing to do that! It has been one of my greatest pleasures, and it has been a personal honor, to participate in adventures alongside of Ernie in California, and in multiple other interesting places all around the world.

It was difficult to see into the deep canyon, because it dropped off so steeply, and because the driver was veering around the bends in the road so fast, racing the Toyota Land Cruiser down the mountain road. This road had no guard rails to prevent us from plunging a thousand feet into the abyss. So, while I would like to have taken a better look at the breath-taking scenery, and I should have captured this part of the adventure with my video camera, all of my personal attention was riveted on the bumpy, narrow, winding road in front of us. I was scared that we were going to fly out over the edge to a certain and violent end! Once in a while, though, I did get a glimpse of a large river cascading down a steady series of natural falls. What an wonderfully-spectacular place! And I did manage to capture the incredible, wild river in the following video segment at one place where we stopped for a moment so I could relieve myself:

The traffic obstacles that posed the most serious threat to our safety were the pain-stakingly slow, and what appeared to be an endless procession, of supply trucks that were inching their way up and down this very steep grade, taking advantage of the lowest gear they had, to save their brakes, those that even had breaks! Our driver, as did all the other drivers of the smaller vehicles moving in both directions, had the hair-raising
challenge of passing the slower vehicles without running into something coming from the other direction. One blind curve after the next placed us almost entirely in the hands of fate. Our driver had no way of knowing whether a vehicle was or was not coming from the other direction, as he committed our vehicle to many of the “go-for-it” passes that we made.

 

I was holding on for dear life!

Madagascar was colonized by the French, so driving is done on the right side of the road. Being on the right side of the road put us dangerously-close to the precipice! At the high speed we were traveling, I was certain my time had finally come this late afternoon! On several occasions, by my calculations, there was no possible way that we were going to make it around the next curve! There just wasn’t enough room on the road to get past oncoming traffic without our wheels slipping over the edge of a very deep canyon. I couldn’t even see the canyon’s bottom! Each “go-for-it-pass” succeeded, either by divine intervention, or by the incredible driving ability of the young Malgasy man at the wheel.

I have lived a pretty gifted life, and I find myself counting my blessings pretty often. It’s not that very much was given to me; I have pretty-much had to climb the painful ladder of success several times. The end-result is all the more sweet when you have to work hard and sacrifice greatly to get there. I have lived on the cutting edge of danger a good part of the time; this is really true! There are not that many more things I feel I need to do before I meet my end of this life. So I find myself saying every once in a while that when the time comes, I am ready to move on to whatever is next. A lot of people say they/we are not scared to die. And you really feel that way when you are saying it! But we only feel that way when we are not looking death right in the eye! When sudden death lurks near, I feel the terror just like anyone else!

As quickly as the hair-raising ride began, we suddenly found ourselves safe at the bottom of the mountain. The immediate danger was over. We were graciously treated to a hot meal and a comfortable bed in the best (and only) hotel in the small village located at the base of the mountain. It was great to still be alive!

This was my fourth expedition to Madagascar in search of gold. Madagascar is the world’s fourth largest island. It is located about 400 miles off the south-east coast of mainland Africa. The country is approximately 1,200 miles long by 400 miles wide (at its longest and widest points). So it is no small country. The country is extremely poor, one of the poorest nations on earth. It is also extremely rich in mineral wealth. Especially in precious stones! Madagascar is an incredibly beautiful and scenic country! For the most part, the country is nearly undeveloped. Although, there are some larger towns that are quite developed. I captured the following video segment in the capital city of Antananarivo, a place where I have spent quite a lot of time:

This preliminary dredge sampling program was on behalf of clients who own some gold mineral concessions in Madagascar. Ernie Pierce was along to assist with the sampling. We were there to get a preliminary idea of how much gold we could recover using suction dredges on two large rivers. We already knew gold was there because of an earlier expedition that we made into both locations to do a preliminary evaluation. Local gold miners were mining gold all over the place. They were mostly panning river gravel alongside the active river. Some were shoveling gravel from the active waterway in the shallow areas. Others were shoveling deeper-water areas out of dug-out boats, using the longest-handled shovels I have ever seen. The native miners were getting gold from everywhere!

As this area was accessible by road, the logistics for setting up a dredging project were not too bad. We arrived with a substantial contingent of people and equipment. We had enough support to move us around, set up our camps, cook for us, do laundry and take care of all our basic needs.

The company we were working for had quite a substantial base camp located where the end of the road met this river. There was a mess hall, some hot showers, individual bungalows; all the comforts of home! Unfortunately, the river near to and downstream of the base camp appeared to have deep sand deposits everywhere. There was no bedrock showing anywhere along that part of the river. Our initial impression was that the sand deposits in that lower section of river were going to be too deep to penetrate using our 5-inch sampling dredge. So we made a plan to pack all of our sampling gear and a fly camp (only basic needs) several kilometers upstream where the streambed deposits were shallow to bedrock. Our intention was to float down river, dredging sample holes through the entire distance back to the base camp.

After initially settling into our fly camp, the primary task at hand was for Ernie and I to determine whether or not the gold here was present in sufficient quantities (over a large enough area) to justify a production dredging program on this river. Ernie captured the following video sequence showing myself, Sam Speerstra (project manager) and Jack (Malagasy manager of our local support team) finalizing a sample plan after our camp was set up alongside the first river:

We spent the better part of a rather uneventful week dredging sample holes on this first river. Interestingly, while local miners were supporting their villages panning gold from placer deposits alongside the river, we could not find any high-grade gold deposits inside the active waterway. Ernie and I devoted long hours to making sizable excavations through hard-packed streambed material to bedrock. And while there was some amount of gold present everywhere, we could find no places where gold concentrated enough to justify any type of production dredging program. While we could speculate about the reasons why, the important thing was that we ruled out the possibility of a commercial dredging program in this area. This was what we went there to do. End of story!

As we did not bring anything extra with us when we packed our gear into the upper area of this river, I was not able to capture video until we arrived back down near the base camp. The video link just above includes a sequence that I took while we were dredging the final sample in front of the base camp. See how deep the light sand and gravel deposits appear to be? We did not expect to find the bottom of this loose streambed material, and we didn’t. But our sampling plan required that we at least try in several areas.

After spending a week on the first river, we were eager to relocate ourselves and our sampling infrastructure over to the second river that we intended to sample, which was several hundred miles away. That process took several days to accomplish. Prospects for commercial dredging opportunity on the second river looked much better to us during the earlier preliminary evaluation. We decided to save this area for last so we could devote most of our time there.

Normally, the first thing we do before making a sampling plan on a new section of river is walk, boat and/or swim the entire length if we can, to see what is there. This allows us to look everything over to see where the best opportunities appear to be. If lucky, we will come upon local mining operations. Those will communicate a lot to us about the prospects. This is because local miners, having spent generations prospecting for gold in the area, will already have a good idea where the best potential opportunities are for the type of mining that we do.

The following video segment found us making a plan on the first morning after we arrived at this second river. The person talking is Sam Speerstra:

Note the active shoveling operations in the river behind where we were pulling the dredge upriver.

How clear is the water?

The first and most important fact of note about the second river was that it was flowing with muddy water. Too bad! Water clarity is the first thing I look for when evaluating a river for dredging. Will I be able to see anything when I get on the bottom of the river? The answer in this case was an emphatic “NO!” This was pretty disappointing to me, because I had been assured by Sam months before, when we proposed the sampling program, that I could depend upon having clear water in this river. As it turns out, this particular waterway drains many thousand acres of upstream rice paddies. It never runs clear!

This was not Sam’s fault. It is nearly certain that you are going to get wrong information from locals in these types of places. With the help of even the best interpreters, communication and understanding tends to break down on technical things. What is clear water to me, and what is clear water to a rice farmer in remote Madagascar, are sure to be widely-different perceptions of reality. Especially when he has never even seen a face mask or a diver before! Over time, on the important things, I have learned to keep asking the same question over and over again in different ways. In doing so, it never ceases to amaze me how many different answers we come up with! Sometimes, no matter how many different ways you pose the questions, you can still never arrive at an answer that you have much faith in. This is not because the locals are lying. It is usually because their perception of the world is so vastly different than ours.

You have to be pretty flexible when conditions turn out not to be the way you expected them to be…

Sam Speerstra is the modern incarnation of “Indiana Jones.”

Sam Speerstra is the true-life incarnation of “Indiana Jones.” Sam has gotten me into and out of more (mis)adventures than anyone should experience in a single lifetime. The last dirty river Sam had me diving in was full of crocodiles and electric eels. That river was a nightmarish diamond project in Venezuela.

Without visibility, there was no way of knowing for certain what was on the bottom of this deep river! I’m not talking about the gold; we can figure that out through careful sampling. I’m talking about the critters!

When I initially evaluate a tropical river for a potential dredging project, the second condition that I evaluate after water clarity is whether or not there are life forms present that are potentially dangerous to me or my helpers. I do this mainly by visual observation. First, I look to see if the local people are working, washing, bathing and swimming in the water. If they are, and they appear healthy; I generally assume that the river is alright to dive in. Although, locals always have a stronger resistance to higher levels of bacteria in their local rivers. So our standard medicine kit on these projects always contains a supply of the best antibiotics to prevent serious types of internal or external infections.

I also ask the locals about sickness and dangerous critters. However, the problem with asking about critters in the water lies with the interpretation. You cannot depend upon only one inquiry or interpretation. For instance, I will never forget the size of the alligator I saw along a river in Borneo several years ago. This was after assurances from our local jungle-guides that alligators did not even exist there. We had been dredging the river several weeks when I suddenly encountered an alligator which must have been 18 feet long! It turned out that these man-eaters were being called “dragons” (not alligators) by the local village people! So I have learned to frame the most important questions in numerous different ways, and I keep asking them over and over again to different locals as I am trying to find things out about a new area.

A lot of local natives were in the river where Ernie and I wanted to sample, so it was probably safe — at least in the shallow portion. You never really know what might lurk deep down in the depths of a muddy, tropical river…

Ernie and his team capturing a little video…

I have accomplished quite a few dredge sampling projects in dirty water. It is a very scary and difficult business. The work involves going down into deep, pitch-dark, frightening places “in the blind,” with no visual assistance. I know that there are live creatures down there that do not appreciate my intrusion into their territory (unless they intend to eat me). To move around cautiously, I have to feel my way by sticking my hand or foot out into complete darkness, feeling around for what is there. Most of the time, before going down, I don’t even know how deep the water is. Sometimes I have to find out by shimmying down the suction hose, reaching out tentatively with one leg at a time to see if I can touch bottom. I am in a state of heightened awareness, desperately hoping that I am not going to touch something that is big and alive. All the while, I am wondering, “How far am I going to have to go this time?”

It is one thing to read about this in the comfort of your computer within a safe environment and feel like you can do it. But you are not exactly the same person when you are dangling dangerously in the dark. You might be the same basic identity; but other parts of you (like terror) get switched on at full volume. I suppose you would really have to go through the experience to fully-appreciate it. Until you do; take it from someone who is used to living on the edge: Diving down in deep, muddy, tropical rivers is not easy!

Muddy water creates total darkness about three feet beneath the water’s surface, sometimes less. So, all you can see down there is what is in your imagination. Do you remember those terrifying nightmares that you had when you were a kid? They still lurk in your subconscious. When going down into deep, dark, terrifying physical places, memories of nightmarish dreams are brought immediately back to life. If you are someone who doesn’t think you are afraid of anything, you ought to try diving in deep, muddy, tropical rivers! You will find there that your deepest fears are just below the surface of your normal, everyday life.

Let me try this a different way: Do you know that feeling when someone startles you at just the right (wrong) time and frightens the heck out of you? Just for that split second, you feel a deeply-seated fear; right on the edge of a panic attack? That is exactly what you experience when you go down into the deep darkness of a tropical river; especially on the first dive.

Nevertheless, over time, I have learned to deal with dirty water. This does not mean that I am not still afraid. I am! It means that I have worked out a way to proceed. Dredging in dirty water is a much slower process. Everything must be done by blind feel, and therefore with care. The process is all about taking control over a single space in the darkness. You get to know every rock in the hole and every obstruction which defines the space. Sometimes, there are submerged trees or other obstacles that you must be very careful around to prevent your airline from becoming snagged. You must dredge alone in dirty water. Otherwise, you cannot toss rocks or roll boulders out of the excavation without a good chance of hurting someone else down there that you cannot even see.

Base camp

Several years ago, my lead diver on a dirty-water sampling operation in Cambodia had a portion of his ear bitten off by a fish. One quick bite and it was gone! That created lots of blood and drama to slow the job down! After that, none of the other guys that I had brought with me wanted to dive. Who could blame them? But we still needed to complete the job; that’s what we do! Surprisingly, it was the lead diver who had to continue the diving on that particular job. I did a little, too; but, that was mainly to show the other guys that I would not ask them to do something which I personally was not willing to do. We wore full dive hoods and dive helmets to protect ourselves from the biting fish, whatever it was. We never saw the creature that took the bite! And as it went, just a few more dives to finish the job proved-out one of the richest gold locations I have ever discovered. But underwater, we couldn’t see a thing!

The primary consideration in assessing a dirty river is how much more time we need to allow ourselves to get the job done in an underwater environment where the divers cannot see anything.

This is one main factor which nearly always undermines the commercial viability of a sizable dredging operation. Who is going to go down and run a 10-inch dredge in zero visibility, 6 hours a day, for a living? The gold deposits will have to be very rich to support this kind of program. I have found several underwater gold deposits that are moderately rich, but they are protected by dirty water conditions. The deposit that we found in Cambodia, for example, would make a dredging operation a lot of money if the diver-visibility problem could be overcome.

People often ask why we need to send divers down in the first place to conduct a gold dredging program. They want to know why the excavation cannot be managed from the surface using mechanical arms. The reason is that sizable rocks along the river-bottom must be moved out of the way of the suction nozzle. Otherwise, one oversized rock (too big to go up the nozzle) after another gets in front of the suction nozzle, blocking further progress until it is moved out of the way. Because of this, with few exceptions, there is no other effective way to proceed without putting divers down into the depths.

These two articles explain the underwater process in detail:

When Ernie and I first started watching the local gold miners on this particular river in Madagascar, we relaxed our fears; because even their small children were bathing and playing inside the river. This was a good break for us!

Now it was just a matter of deciding where to do our sample holes. Ernie and I used a two-pronged strategy that we have developed over the years for these situations. First, we dredge sample holes near and in line with where the local miners are actively achieving positive results. Most high-grade gold deposits follow a common line down along a waterway. For example, see how the following important video segment shows how the many local digging operations inside the river are following a common path. If you look closely, you can see tailings remaining from previous digging activity right on the same path. To get our own sampling operations off to a good start, we usually begin along the same path in the river where most of the local miners are working:

Secondly, Ernie and I offered financial rewards to the local miners for each place they showed us to dredge where we could find lots of gold. Such places are usually in the deeper areas where locals cannot gain access using the gear at their disposal. A “grande” reward goes to the person who shows us the place where we find the most gold. Wow, this incentive sure got Malagasy miners talking; and we started to find a lot of gold!

We moved our sample dredge in direct line with where local miners were doing well working out of dug-out canoes using long-handled shovels. This got us into rich gold right away!

Since we could not see how deep the water was in this dirty river, and because we had already established that there were some deep deposits of sand and loose gravel along the bottom that we wanted to avoid with our 5-inch dredge, before doing dredge samples, we used a long steel probe to find areas along the established gold path where the water was not too deep for us to reach bottom, and where we could reach hard-packed streambed without having to go through a deep layer of sand first. The following video segment shows how we performed this important pre-sampling process:

In one location, I decided to sample directly underneath a native “boat-mining” operation. I did this because I noticed the natives were working the location very aggressively. This is always a good sign! They were using long-handled shovels, about 20 feet long, from anchored boats well out into the river. The water was at least 12 feet deep! These shovels were especially designed to bring gravel up from deep water. The natives were very good at it. Have you ever tried shoveling material from underwater? Nearly all the material washes off the shovel before you can get it to the surface. Not with the Malagasy boat miners, however. They were bringing up full shovels every time. The material was being panned at the surface.

The following video segment provides a firsthand look and explanation of the boat-mining which we saw when we first arrived at this river. Seeing this type of active mining along the river by local miners was very encouraging, and immediately helped shape the sampling plan which Ernie and I would follow:

As it turned out, local miners from the boat-mining operations had plenty of gold to sell! They were anchoring their boats out in the river by driving hardwood poles deeply down into the streambed material, and then tying their boats off firmly to the poles at the water’s surface. The boats needed to remain stationary to allow the miners a firm platform from which to work the hard-packed streambed material along the bottom of the river. Consequently, we could look along the river and see many stakes remaining from earlier mining activity. Unsurprisingly, most of the stakes followed a common line down the river as far as we could see. We still needed to confirm it by sampling, but Ernie and I had a pretty good idea where the high-grade gold line was located in this river even before we unloaded our sample dredge from the truck. This was good!

The following video segment shows how we went about our sampling program. Notice the wooden poles out in the river? Because there was zero visibility underwater, you will see that Ernie had to keep jumping up to peak his head above water to steer himself and the dredge out in line with the poles. Where the water was too deep for that, we had to shimmy up the suction hose to have a look. Sometimes, it was so difficult to find our way in the dark, that we first positioned the dredge out on the river using ropes, and then shimmied down the suction hose in the dark to take a sample:

Ernie and I felt it was important to get one sample directly under one of the active boat-mining operations. This was so that our clients could estimate the value of gold deposits that local miners were developing in the river, and to see if they were excavating all the way to the bedrock. I was the one to dredge that particular sample. To accomplish this safely, we paid those particular boat-miners to stop digging for a few hours while I was under their boat.

As we had to drive our dredge out past the middle of the river to reach their hole on the bottom of the river, it was quite a challenge to find their hole in the pitch dark. When I finally found it, I was amazed to discover that they were actually penetrating deep into the hard-packed streambed material with their long-handled shovels. This must have presented them with a substantial challenge, because the cobbles were tightly interlocked together. At the bottom of their excavation, I found that their shovels were touching on bedrock, but that there was no way for them to take up the highest-grade material which was resting directly on bottom. They also were not able to clean the natural gold traps inside of the bedrock where most of the gold should have been. Too bad!

Being mindful that I was dredging in a high-grade deposit that had been previously located by other miners, I did not stay under the boat-miner platform any longer than it took to dredge up about a cubic meter of the hard-packed pay-dirt off the bottom. The material was only around four feet to bedrock; an easy place to dredge even in the dark water. We recovered a lot of gold proportionately to the volume of streambed that I processed. My estimation is that the river could produce 5 ounces of gold per day in dirty water using a 5-inch dredge.

The following video segment shows the gold we recovered from this sample, and captures my summation of what we needed to do to complete our preliminary sampling program on this part of the river:

 

 

The gravel being brought up from the river bottom by local miners was panning out very well!

As it turned out, the local miners were greatly impressed and worried by our dredging machine. They watched the volume of gravel wash across our sluice box, while they were bringing it up one small shovelful at a time. Prior to our arrival on the scene, they were the biggest and the best miners around! They could put two and two together, however. After our test under their boat, they began 24-hour boat-mining operations in that location. You could see their campfires down by the river (for light) burning all night long. Within a few days, there were a dozen boat-mining operations going full blast, 24 hours a day. They were worried we were going to return and dredge up all their gold. As good as their discovery was, we were not going to do that. Our sampling thrust thereafter was to determine if the high-grade streambed material extended downstream; and if so, how far?

There was certainly high-grade gold at the bottom of the river!

I’ll never forget Ernie’s first deep, dirty-water dredging dive. I could see that he was pretty nervous about taking the dive, so I offered to walk (crawl) him out into the river for the first time. He agreed to this. After everything was up and running, I took Ernie by the hand and crawled alongside of him in total darkness out to the middle of the river. It was a long way out to where Ernie was going to help finish the sample that I had already started. We grabbed onto the suction hose and dragged the dredge out into the middle of the river, instructing the dredge-tenders to allow the dredge to follow our bubbles. The water was about 12 feet deep in the middle of the river. I could tell that Ernie was having a difficult experience by the way he was gripping my hand. He was holding on for dear life! Finally, Ernie had enough and he began giving me the signal that he wanted to go back to the shore. I got the message immediately from the way he was grabbing me with both hands and jerking me toward the dredge. After we returned to the surface, Ernie told me that he was just “not up to it.” He had that look of panic in his eyes, a feeling I personally know very well! There is no use in trying to push anyone into doing something while they’re in a state of fear and panic. As I have said, it is not easy diving in dirty water! We all have a limit, beyond which we are not willing to go!

Instead, I urged Ernie to do some initial sampling in shallow water so he could get a feel for it. He could work standing up, with his head out of water, if he needed to. Ernie was up for this and immediately went to work closer to the shore. We needed to get some samples over there, anyway. A few minutes later, on his own determination, Ernie went bravely out into the middle of the river and was taking samples from the particular area where we really needed them; in line with where the locals were getting the most gold for their effort. Dirty water dredging is an experience you really have to ease into at your own pace. Ernie adapted quickly, and was soon working efficiently. I could tell this by the continuous gravel which was washing across the dredge’s sluice box.

Locals observing Ernie do a final clean-up

 

Each of us has our own personal limits. Would you walk a tight rope suspended a thousand feet in the air between two tall buildings? Most of us wouldn’t! What would it take to get you to do it?

It takes a lot of personal courage to go well beyond our normal comfort zone into the realm of personal terror. The type of work I do often allows me the opportunity to watch others confront their own personal limitations. In defining this particular character trait of an individual, it is unfair to make your judgment based upon where the initial limits are. True courage is tested when a person is confronted with the need to go beyond personal limits, no-matter where the limits are! I was very honored that day to be present when Ernie overcame very personal and serious fears, and went out into the middle of the river to help accomplish what we were there to do.

On one occasion, Ernie came up the suction hose in a real hurry! I saw the dredge bob up and down as he pulled himself up the suction hose. As it turns out, Ernie was walking around on the bottom of the river (total darkness), and he stepped off into a “bottomless hole”. When he got to the surface, Ernie said that it all had happened within a split second. He suddenly found himself dangling like fish bait from the end of the 20-foot suction hose directly over the “depths of hell.” Luckily, the weight of his body did not pull the suction hose free from the power-jet. I have had the same experience happen to me in dark water. So now, I am careful to take only small steps, feeling my way along the bottom slowly to avoid frightening surprises!

One of the most important things to do in any sampling program is test the efficiency of the recovery system that is being used. To do a proper job of it, you must establish how much of the target mineral (gold, gemstones or whatever) that your recovery system is not catching when processing the raw material from each sample. You cannot just assume the recovery system being used is providing 100% recovery. You have to make regular tests of your tailings using other recovery equipment that can provide the most accurate results possible. During a preliminary sampling program, this usually means careful panning of random tailing samples.

On this program, since we had plenty of very experienced local panners giving us support, whenever possible, we directed our dredge tailings over near the riverbank where our helpers could pan everything that passed over the dredge. They would then show us what we were losing from the dredge.

Since our most important samples were dredged out in deep water, Ernie and I ended up building a wooden box that we were able to suspend from its own floats and catch all the tailings from our dredge. After each sample was complete, while we processed the dredge concentrates through our special concentrator, local miners would carefully pan all our tailings for us.

As it turned out, our losses from the dredge initially were quite substantial. This river had a lot of fine-sized gold that was just passing through our recovery system into tailings with sand. Within the limitations of the tools we had available to us in the field, Ernie and I tried different ideas to improve the dredge’s recovery system. Ultimately, Ernie came to the conclusion that the classification screen needed to be raised further away from the riffles in our sluice box. This allowed more water flow to help the riffles to concentrate. Working this out in the field gave us important insight into what would be needed in the recovery system on a commercial dredge in that area.

The following video segment shows the process we were following to work out how to recover the substantial amount of fine gold we were finding in the river-bottom deposits on this river:

 

 

 

 

 

BY GENE MEDENWALD

 

Yesterday’s production was nine pennyweights and 22 grains–just a tad shy of one-half ounce of gold. This was the very best I’d ever done with my five-inch suction dredge. The very best I’d ever done in my life! I was excited. I was obviously getting into a really good pay-streak. The gold was less than half fines, with a lot of wheat kernel-sized pieces, and a few quarter and half-pennyweight chunkies, some attached to quartz.

Things were going good and looking better. Yesterday had been a long day, but not as long as I was able to work; about three and a half tanks of gasoline or seven hours. Today, as planned after the gold weigh-up last night, I was at the river early, determined to put in at least a four-tank day . . . and pull my first half-ounce of gold in a day!

Though the water’s flow was quite strong and the water deep, I had an excellent hole developed and it was comfortable working it. I was developing cuts forward and to the right. First, a layer of sand and small cobbles, then down through a layer of gray and blackish clay-like old hydraulic mine tailings, and finally into a beautiful yellow/orange boulder-strewn hard-pack laden with flecks of yellow gold throughout–and last, onto crevassed and jagged bedrock where the wheat kernels and golden chunkies were. Man, this was FUN! This is what gold mining should be. This is what people have been telling me it is like, and all of this time I kept wondering if it was true and if it would ever happen to me. Now I am really doing it and it is wonderful . . . thoughts like these were running through my mind when suddenly: WOW! Something is pulling on my suction hose. Pulling strong! This is weird. I can’t hold it back! I’m being pulled out of my hole! Rats, it slipped out of my hand. Sheez, now it’s pulling on my airline! I’m on my back, now buffeted and rolling about in the current.

Don’t panic! You’ve still got air. Clear your mask so you can see! Where am I?

That huge boulder; I must be about 15 feet from the ledge; on the other side of the boulder, just a ways, where it is only four feet of water and mild current–get there! I was slowly moving by laborious and exasperating crawling against the strong current, slipping and sliding over the slick and mossy rocks, resisting the constant pulling on the air hose. And while doing so, I was thinking, a little more calmly now, will the strong air line break? If it does, I can always drop my weights and “bail out;” where’s the weight belt buckle, dummy? Yeah, the weights are all at your stomach, the buckle is at your back; pull the belt around so if that air line pops, you can reach the buckle.

Totally exhausted, I finally, made it to the boulder and to the shallow, quiet water and stood up and automatically raised my face mask and spit out the regulator to gasp for open, unrestricted air — and was SHOCKED and dumfounded to discover I was standing in a deluge of water, blasting at me from the sky! And the smell, the foul, disgusting odor, the stench; ack, gasp, gag! Drop the weight belt, the mask, the regulator, the everything and swim the hell away from there!

That is a very brief description of how I experienced and survived an example of Murphy’s Law and several of its corollaries that day.

Experiencing it was frightening — fright caused by what was happening to me physically, fright caused by fear of the unknown. (What in the HECK is going on? Did my hi-line break? Is my dredge towing me downstream to the rapids?) Experiencing it was also incredibly physically exhausting, and nearly debilitating from stench-induced vomit. The cause of all this was simplicity itself: the pressure hoses blew off the dredge pump. No big thing. Murphy’s Law: If anything can go wrong, it generally will!

A miner’s suction dredge is, of course, a machine. Lots of moving parts. Lots of things to go wrong. But I was dredging three-fourths of the way across the river; and when a pressure hose blows off the pump of a five-inch dredge with the engine going wide open, and with the current and the hi-line set up just right (just wrong?), the whole dredge becomes a jet boat and zooms before the immense force of water being blown from the pump with great power. In my instance, it dragged me 30 feet across the river bottom, and of course (Murphy’s Law), lodged against the bank, in a backwater eddy chock full of floating long-dead fish and eels, carcasses so rotten that the water intake simply sucked them to pieces and the pump blew them into a huge spume of a rainbow-like arch of solid water under which, by chance (Murphy’s Law), I had the misfortune to surface!

What an experience!

And what a horrible job it was to correct everything and get back to mining for gold.

I reeked of dead fish. There were particles of stinking dead fish and eels all over my wetsuit, and all over my mask (when I finally recovered it after an hour’s search with my spare and snorkel) and the regulator/mouth piece. I had to completely disrobe and wash all of this with lots of soapy water in my clean-up tub. Then I had to hike back to camp for my chest waders so I could extract the dredge from the backwater eddy and the mushed-up rotten fish stew. The Law did display a little grace (pity?) though; because the dredge engine quit running shortly after I surfaced and I at least did not have to wade into the rotten fish stew to turn it off. It was a big job representing a lot of unproductive labor, but I eventually did get back into the river again that day and was able to run one more tank of gas before dark. Needless to say, I did not reach my goal of one-half ounce of gold that day.

At the time when this event occurred, two seasons ago, I must admit I rather soundly cursed Murphy’s Law and all of the gods of wayward, askance, and evil fortune. But on reflection, was it really The Law or just dumb o1′ me?

I had been advised and warned about that pressure hose. I really had. I did nothing about the advice. It was an old but serviceably-good dredge. The flange on the pump had been reduced in size from years of tightening. The pressure hose was old and stiff, and it was really too short.

How silly we are at times, to our own detriment. After several more “blow offs,” I eventually replaced the hose with a longer one, which was cheap and thin and kept getting holes in it which reduced suction intensity . . . only to finally replace that one with a correctly-specified one which again blew off because of the small flange. Finally, I simply had a miner-friend weld on a threaded pipe nipple and used a fire hose fitting like those on the newer dredges.

I could have done that simple alteration before I ever put the dredge in the water that season . . . and maybe The Law would have ignored me completely–well, being miners we know that can’t be true.

The other day a young man up here on an exploratory visit stopped by where I was working and we shared a cup of coffee. During the course of our conversation, he began to elaborate to me the intricacies of the Thomas T-80 air compressor with which my dredge is equipped, as are most suction dredges these days. I listened as politely as I could for a while and then got out my daily log book and began reading a few old entries to him:

May 19–0n the Little South Fork of Indian Creek. Inadequate air. Something is wrong with the air compressor.

May 20–Repaired compressor. A broken piston reed.

May 22–Reed in compressor broke again. Repaired it with last reed in Pro-Mack Shop.

May 25–Reed in compressor broke again. Repaired it with one scavenged off Dave Mack’s spare, at his generous offer. This is getting exasperating.

May 27–Air compressor reed broke again (the fourth one). I am depressed. Visited Dave Mack about it. He says one can expect a reed to occasionally break, usually after many, many hours of diving. Certainly not every other day. Possibly the pulley ratios are wrong on my dredge and the compressor is running too fast? (His suggestion.)

May 28–Spent the day borrowing a pulley tachometer. Took readings off my dredge (not a Keene) and readings on another miner’s Keene dredge. My compressor is running three times faster than his!

May29–Drove to Yreka to obtain new pulleys and belts and made necessary alterations on my dredge. Cannot try it out yet because I used up every spare compressor reed in town. Must wait for new parts to arrive.

June 1–0n Thompson Creek. Hurray! Got new reed for compressor and moved to sample Thompson Creek and have wonderful, wonderful AIR!

June 2–Air compressor broke again. A screw apparently came loose from the problem reed and bounced around on top of the piston until it cracked and shattered the upper reed plate.

June 3–Depressed. Didn’t dive. Repaired air compressor in p.m.

June 8–Moved to Klamath River near Tim’s Creek. Sampling.

June 12–Still getting inadequate air. Took compressor apart and discovered eventually that all of the pieces from the broken reeds, etc., have apparently caused holes in the diaphragm. Replaced same, and for the first time in nearly a month seem to have adequate air.I am not convinced that I can strip down and repair the Thomas T-80 compressor in the dark. I am infinitely more familiar with it than I ever became with my M-1 rifle in the Army.

June 16–Damned near drowned myself for lack of air and panic. Tipped the dredge upside-down with engine running full out. A quick but rather dubious way of stopping the engine!

The Law almost did a final job on me that June 16. I was using a three-inch dredge, one with great suction through 30 feet of hose and was sampling extensively.

I had just made my first dive in quite deep water (for me at the time), probably about 15 feet, and was working off a hi-line for the first time and had gone quite far off the bank into fast(er) water.

Breathing is such an automatic function of our almost magical bodies that the average person, I think, rarely ever considers it. I’ve visited with many diving, dredging miners who have never had an air mishap who barely consider it. It is such a simple function. Exhale carbon dioxide, inhale air.

However, when you are a relatively inexperienced hookah diver and are in deep and fast water for the very first time in your life and, having exhaled and when you attempt to inhale, your body receives nothing, nothing at all, like sucking on a hose with a plug in the other end, that is decidedly an arresting situation!

Your mind immediately goes wild with random suppositions and questions and images. How much air is left in your lungs for your body to use after you have exhaled? How far off the bank am I? Don’t panic! Should I drop my weights now? Don’t panic! N-a-a-h. That’s a chicken’s way out. I’ve got time. Don’t panic! Just keep moving, calmly, toward shore. There is nothing left in my lungs! Don’t panic! (All the while I am scrambling up a soft sand bar toward the river bank, slipping and sliding and being washed downstream by the current.) Don’t panic! I-am-going-to-pass-out-soon-it-is-time-to-drop-the-weight-belt! There-is-a-weight-where-the-buckle-should-be!

WHERE’S-THE-BUCKLE?!

I simply do not remember what happened after that or what I did next. I DID PANIC. My next conscious memory is of a fellow miner holding me as I was floating in the water, gasping and gasping for air, as he kept repeating over and over, “Are you alright?” I was, kind of, alright and The Law didn’t get me down in finality, but just by a bare smidgen. I think my poor friend was much more frightened than I was during those climactic moments.

The scene as he recalled it: as he, too, was sampling, he was peacefully panning the concentrates from his most recent sampling hole and my dredge was purring away about 30 feet off the bank. Then he observed my dredge moving slowly toward shore and when about 15 feet off-shore this maniac erupts violently from the water, his mouthpiece/regulator goes flying through the air, he takes a huge gasp and sinks below the surface again, turning the dredge completely upside down! Moments later, the madman surfaces again, floating on his back and goes drifting downstream toward some rapids, repeatedly gasping for air. The fellow then dove into the river, swam out to me and pulled me to shore.

Later, after we’d both calmed down a bit, we found my suction hose nozzle, my weight belt and my crow bar all directly under the overturned dredge. The conclusion we came to was that I must have climbed up the dredge suction hose for a desperate breath of air, then found the buckle to the weight belt, released the weights and popped to the surface.

The cause of the air stoppage? Bits and pieces of compressor reeds and diaphragm rubber lodged in the airline where the yellow line connects to the black regulator line. Simple! If after each problem with the compressor (which was a problem I had caused and not a fault of the machine), I had simply opened that connection and permitted the debris to blow out, I (and not The Law) would not have nearly killed me.

Also, if I had simply taken the few seconds necessary to drop my weights before a bad situation became a panic situation, nothing really dramatic would have happened. I kind of think macho-ing and diving, like drinking and driving, don’t mix very well.

I am now a more experienced hookah diver and a more experienced dredger and a more experienced miner. I have a giant respect for Murphy’s Law and its corollaries–and I’ve tried to learn from the “anythings” that have happened to me. Some of the things Murphy’s Law have taught me:

Do not dive with crumby, unproven equipment. If you have garbage gear, and your gold production won’t permit purchasing better stuff (and that’s probably why), get a job and save your money until you can buy the right good gear.

Do not skip or postpone the most minute maintenance or repair task. Fix it now, before the next dive, even if it means hiking back to camp or running into town in the middle of the day when you are just entering a great pay-streak

Don’t Dredge Dumb. Use your head. Develop your hole safely and methodically as is described in the book, Advanced Dredging Techniques by Dave McCracken.

“Ever have a prospecting trip where everything went wrong?”

 

Image 1Three months of planning, over a thousand miles of traveling, anticipation of gold pans shining with stringers of gold — then, almost everything went wrong!

It had been quite a while since I had taken a 12-day prospecting trip. I am tied to work obligations, as most of us are; and it is rare to have an opportunity to escape and do what I love for that length of time.

The plans began several months ago, when my prospecting partner, Gail Butler, and I were invited on a nugget-shooting hunt. Two friends of Gail’s, Marc Davis and W.R.C. Shedenheim, of Rock and Gem Magazine, had researched the old dredge tailings near Sacramento, and had asked us to join them this past October for a group hunt.

Gail and I decided we would “dig our way” up from Los Angeles and do a little bit of high-banking on the Stanislaus River, near Columbia, before heading up to Sacramento.

Image 2The trip to Columbia was uneventful; but it was a very, very long drive. We finally arrived at the road which would lead us down to the river. As we descended, we saw ahead of us large billowing clouds of smoke coming over the mountain ridge. We could not believe that we had driven all this way and the mountain was on fire! This was not a canyon that you would want to get trapped in. As we watched the smoke increasing and nervously viewed a bomber plane flying overhead, a truck was approaching us, coming out of the canyon. We waved the man down and asked if he knew what was happening. He replied that it was just a controlled burn — we were extremely relieved. That relief quickly disappeared when the man left us with the statement “But those burns don’t always remain controlled.” What a comforting thought! We decided to go down anyway, finally finding a clearing near the river which looked great for camping and high-banking.

Opening the back window of my truck shell was like releasing the top of a Jack-in-the-Box. I had decided not to take my tent trailer, because we had planned, on the return trip home, to do a little gold prospecting in an area above Death Valley. The roads there are not very kind to tent trailers. So, my truck was packed with every camping item you could imagine, along with high-bankers, sluices, metal detectors and all our personal belongings. Once I removed the much-needed bungee cord, out popped everything.

The first sign of bad luck hit us just after setting up camp. With the truck now empty, I discovered that I had forgotten most of my clothes. Ten minutes later, when I attempted to take a picture of camp, I found that my camera was broken. I joked with Gail about “What else could go wrong?” The answer came the following morning. We woke up to an pretty substantial rain storm. Gail’s hat was floating around in a pool of water that was on the floor of the tent. I had owned this tent for years; but it had never been rained on before. The ceiling wasn’t leaking, but the side-seams certainly were! Everything on the floor was soaked. Everything outside — the stove, the lanterns, and supplies — was soaked. This was not fun!

Within an hour or so, the rain finally let up enough for us to head for the river and start high-banking. After setting up all the equipment, I proceeded to crank-up the engine and guess what? It would not start! The engine had not gotten wet and it had never, ever acted like this before. After about 45 minutes, I finally got it to turnover.

The rain continued on and off for four days. I don’t recall that we were ever reallydry. We found one nice nugget, but it was very difficult trying to shovel mud into the high-banker.

About two days into this wonderful trip, we met two other prospectors who were camped downstream from us. Larry and “‘Half-Bucket,” as he called himself (because he only moved a half bucket of dirt a day), kind of felt sorry for us and thought it would be nice to cook us a dinner. They had RV’s, so they did not have to cook under a tarp.

Gail and I are not in the habit of accepting invitations from strangers, but these gentlemen were gentlemen, and we felt it was all right to go for a dry meal. At dinner, Larry brought out some Irish Crème that he had made himself. Neither Gail nor I are really drinkers, but it sounded like a great idea on this cold and rainy night.

After drinking about a quarter-Dixie cup full, I realized something was very strange. I could not feel my legs! I was told later that I was walking and stepping as if I was trying to walk up steps — but there were no steps! I finally asked Larry how he made his Irish Crème, and he confessed that in place of whiskey, he used 190-proof moonshine that was being made by some hardrock miner down the road. I am not sure how Gail felt, but I felt as though I was under anesthesia for the next two days.
On the fifth day, our day of departure, we woke to rain again.

Have you ever tried to pack-up a six-person tent that is soaking wet? Not easy! We barely had enough dry clothes to wear for the trip up to Sacramento. I could not wait to get to the hotel. When: we arrived there, we immediately found a Laundromat to wash all of our “mud clothes.” Can you imagine looking so bad that people in a Laundromat were staring at you? And these people were campers as well!

After a night of rest in dry beds, Gail and I connected with Marc and W.R.C. for our first day of nugget shooting. Rain was again threatening, but we all figured we would go for it anyway. Marc had gone to great lengths to secure permission to detect the old bucket-line dredge tailings that were located on private property. But at the first site, after gearing up and getting started, we were asked to leave. Apparently, several owners were involved, and the two owners who had granted permission to Marc had not told the third owner of their actions.

On the second day, after arriving at an area that we could hunt, we found an incredible valley that went on for miles, covered totally with old bucket-line dredge tailings. Again, the weather was threatening; but the landscape was so beautiful, you could almost forget about the impending storm.

Most of the tailing piles were over 10-to 15-feet high and covered with various sizes of river rock. About mid-day, as I attempted to climb one of these, I lost my balance and fell forward, head first, and then down on my stomach. Down the tailing pile, I slid as if my body were a sled on a snow hill. When I finally hit bottom, as I lay there, I was looking around to see if any of the group had seen me exhibit this graceful attempt at metal detecting. I was a bit banged up, but nothing serious. We found no gold; but it certainly was not because we didn’t try.

On the last day, heading back to the hotel, it started to hail and I wondered — when were the locusts coming?

Gail and I decided on that last evening that we had better go back to Los Angeles for a couple of days, dry everything out, and then proceed on to the area above Death Valley. We re-mapped so that we could return on Highway 395, and I could drop Gail off in Upland.

Well — the curse was obviously not through with us! Just about eight miles out of the town of Mojave, we smelled something burning in the truck, and snap went the fan belt! There we were on a stretch of Highway 14 right between two high mountain peaks.

I mention that because, of course, my CB radio was worthless to me in the canyon. It was very windy and cold, and I was out making hand signals to the drivers of the big rigs to call for help. I am not sure how this looked; because some of them looked at me like I was crazy. I was crazy!
Finally, we saw a California Highway Patrol (CHP) car on the opposite side of the highway. He looked over at us, got off the freeway, came back on our side and drove right past us! We could hardly believe our eyes.

To make a long story short, a Deputy Sheriff finally stopped and called for a tow truck. He was kind enough to stay with us until the truck arrived. During the wait, CHP and other Sheriffs then stopped to see what was going on. It looked like a crime scene!

After a couple of hours in Mojave, and an unwanted repair bill, we finally headed back home. I enjoyed every minute of my two-day “drying out” time at home. The second leg of the trip would only be an overnighter, so at least I didn’t have to pack very much.

I picked Gail up and we were off to an area in the Clark Mountains above Death Valley. We had planned to go to an old abandoned mining camp that Gail had found and written about a few years earlier. This camp had been deserted for over 40 years; but when we got there, the old buildings had been replaced with new ones and the old mining equipment replaced with a new backhoe and trucks. There were “NO TRESPASSING” signs everywhere. We had just driven six hours to do some metal detecting at this place!.

We do not give up very easily, so down the road we went to investigate some other old mining areas. Darkness came quickly, and we had to find a place to camp for the night. After settling behind a large knoll, we emptied the truck only to find that the lantern had no mantles and the flashlight batteries were dead! We had not brought spares of either item. Can you believe that?

We left early the next morning for home. This was the last leg of our 12-day trip; and although we had our share of bad luck, we did have some good times, as well. That was, until while driving home on Highway 395, just five miles out of Kramer Junction, the clutch on my truck decided that it would quit working. This was just to show us that we were not yet done with our “trip from Hell!”
So remember O’Reilly’s Law, Murphy was definitely an optimist!

But don’t ever give up! My next trip, and all of our trips, will always bring a moment of joy that only we prospectors and treasure hunters understand. Good Luck!!

Sometimes, you will find that you are as close to winning as you can be, even though things have never looked worse!

Dave Mack
 
A short time ago, my dredging partner and I were sampling in a new section of river. We were looking for high-grade pay-streaks, dredging test holes, and hadn’t had any luck from five very well-done samples. We floated down to a new section of river, where the water was very fast. It was on the inside of the tail-end of a bend of the river–an excellent place to find a high-grade pay-streak.

The problem was that we hadn’t found a single speck of gold in the previous five sample holes. This was uncommonly-bad! Usually, we at least find some showing of flood-gold in every test hole in river-dredging. For the most part, I had decided that this section of river must have been very low-grade. We had about a half-mile left downriver to the next river access–where we would be able to pull the dredge back out of the river. So, we decided it was worth a few more sample holes as we drifted down in that direction.

This new section of river had slow water towards the bank. I had it figured that the pay-streak would be located out under the fast water — which is often the case. I don’t know why, but mother-nature often has a knack for hiding her natural treasures in areas which are more difficult to get into!

We set up the dredge in the slower water alongside the bank, got everything running, and I started the sample hole right out on the edge of the fast water. Once the hole was down far enough to protect me from the current, I pushed the hole out under the fast water where I figured the pay-streak would most likely be. This was very difficult, because the force of water was pushing very hard against the suction hose and my airline. I just muscled the work through against the current, but it took a great deal of effort. I was in that zone where heavy effort, physical pain, and emotional stress are all the same?

The suction hose was swept back into the current several times, which required me to go back, drag the hose over towards the bank, pull it back upstream, and get it back out into the sample hole. All this, to keep pushing the hole further out into the current, and deeper towards bedrock.

When I reached bedrock, I uncovered it slowly to see if there was any visible gold in the cracks. All I saw was a few small flecks–nothing to get excited about. It was gold, however; and seeing it on the bedrock was encouraging. It was the first gold we had seen in that section of river. Seeing the flecks on the bedrock meant that I was beginning to dial into the right wavelength!

Having it in mind that the best gold would be further out into the current, I pushed the hole in that direction. The further I pushed, the more difficult it was. The bedrock out there showed no gold. My arms felt like spaghetti!

So I pulled back into the original place where I spotted the gold flecks on bedrock, took another small cut off the front of the hole, and worked it down to bedrock slowly so I could see if there was anymore gold. I did not see any. So I assumed this area must also be low-grade and decided to call it quits.

As I was dragging the dredge’s suction hose in towards the bank, the thought crossed my mind that I ought to test the inside of the dredge hole–over towards the slow water.

If the streambed material had been deeper, it is likely I would not have tested toward the inside. Why? Because I had it in my mind that the pay-streak was out under the fast water; not under the slow water. But, because the streambed was shallow, and I had seen some gold on the bedrock where I first touched down, I decided to take a quick cut off the inside of the sample hole.

Sure enough, I spotted several small flakes of gold on the bedrock. So I took a larger cut off the inside, pushing towards the bank. About halfway down to bedrock, I started seeing flakes of gold in the gravel–kind of like Christmas. On the bedrock, I uncovered a pothole full of gold; it was about eight ounces in all–about half of it was jewelry gold. And that began one of the richest pay-streaks we ever found!

There is a lesson in this!

Everything we do, everywhere we go, is the result of the decisions we make. Sometimes we get going on a path which is just not the right direction! This is not just in gold mining. Sometimes the signals are there, telling us we are going the wrong way — often by the amount of pain and discomfort and effort it is taking to keep moving in the wrong direction. Have you ever found yourself in a major difficulty — only later, sometimes much later, to realize that it was one of the best things that ever happened to you?

The lesson is to never give up hope! Never say die! Sometimes, you will find that you are as close to winning as you can be, even though things have never looked worse. This is especially true in gold mining.

This is not to say that you should keep pushing hard in a direction that is not working. It is to say that if one direction does not seem to work, take it a little further, and then look around for another way to go. Don’t get fixed in one mind-set. Ask yourself what you are trying to accomplish, and keep your awareness open and your imagination working to find the available opportunities to accomplish your goal.

We manage group gold mining operations in northern California just about every other weekend during the spring, summer and fall months. During these operations, it is my personal responsibility to make sure that silt, sand and gravel are not washed back into the river off the bank from our tailings-water. This requires continuous effort to keep tailings water directed along the natural contours on the land outside of the river. Sometimes I spend a lot of time running up and down the bank trying to stop the water or slow it down. One thing for sure, if you stop the water in one place, pretty soon it is running down the bank somewhere else! Gravity is a force of energy that never stops.

In many ways, this is not dissimilar to a person’s intention to accomplish a goal. Sometimes, we will find our immediate progress slowed down or stopped altogether. But if we maintain our intention, and study the barriers to our progress, we can usually find other ways to make progress. The key is in maintaining the intention, keep pushing along, and having a little patience.

The best things in life usually take a little time to accomplish. And the best memories often come from the accomplishment of difficult goals.

“Dredging for Diamonds and Gold During the Rainy Season…”

Dave Mack

 

Author’s note: This story is dedicated to Alan Norton (“Alley”), the lead underwater mining specialist who participated in this project. Under near-impossible conditions, Alan made half of the key dives which enabled us to make this a very successful venture.
There are very few people I know, if any, with more courage, dedication and enthusiasm to successfully complete a difficult mission, than Alan.

If I can make it go right, I try and go overseas at least once or twice a year, usually during our winter months in California, to participate in some kind of a gold mining or treasure hunting adventure. Sometimes I am paid as a consultant to do preliminary evaluations for other companies. Sometimes I just go on my own. Doing these projects in remote and exotic locations is kind of like going back into time, or like going into a different universe. It is always a great adventure! Sometimes, on these different projects, everything goes smooth and easy. Sometimes we uncover fantastic riches. Sometimes we find nothing at all of great value. And, once in awhile, conditions are extraordinarily terrible and put all of our capability and courage to the final test. Such was the case on our recent testing project into the deep, dangerous jungles of southern Venezuela.

Venezuela lies on the north coast of South America along the Caribbean Sea. It is a South American country that ranks as one of the world’s leading producers and exporters of petroleum. Before its petroleum industry began to boom during the 1920’s, Venezuela was one of the poorer countries in South America. The economy was based on agricultural products, such as cocoa and coffee. Since the 1920’s, however, Venezuela has become one of the wealthiest and most rapidly changing countries on the continent. Income from petroleum exports has enabled Venezuela to carry out huge industrial development and modernization programs.

Columbus was the first European explorer to reach Venezuela. In 1498, Columbus landed on the Paria Peninsula. In 1498 and 1499, the Spanish explored most of the Caribbean coast of South America, and Spanish settlers were soon to follow the explorers.*

Almost all Venezuelans speak Spanish, the country’s official language. Indians in remote areas speak various tribal languages.*

I personally was contacted by an American investment group that was in partnership with a Venezuelan mining company. They hired me to spend around thirty days doing a preliminary testing evaluation on a concession (mining property) the company owns in the deep jungles of southern Venezuela. The property was reported to contain volume-amounts of gold and gem-quality diamonds. A river flows across the concession for approximately twenty-five miles.

The company had purchased a 6-inch dredge along with the support equipment. They wanted me to complete a dredge sampling program to see what kind of recovery we could obtain from the river. I brought one other experienced dredger along by the name of Alan Norton. Alan and I had spent several seasons dredging together on the Klamath River in northern California, and I had learned years ago to always bring at least one very capable teammate along when doing diving operations in the jungle environment. This proved to be a really wise decision!

We flew into Caracas, which is the capital of Venezuela, a very nice, modern city with big office buildings and hotels creating a beautiful skyline. Caracas enjoys the reputation of having one of the best night-lives in the world. Poverty is also visible along the outskirts of the city where thousands of people live in small shacks called Ranchos.

The company put us up in the Caracas Hilton where we spent a comfortable night, only to fly out the following morning to Ciudad Bolivar–which is a fairly large city, and the diamond capital of Venezuela.

Upon arriving in Ciudad Bolivar, we were promptly met by representatives of the company, along with the company’s bush boss, an American adventurer by the name of Sam Speerstra. Sam would make a good match for Indiana Jones. It was quickly apparent that he loved danger by the way he drove us through traffic to the small landing strip that we were to shortly depart from on our way to the concession. Sam had us unpack our bags while he arranged to have the aircraft pushed out onto the runway by a half dozen or so airport workers.

The dual engine aircraft was not in the best state of repair. The engine shrouds were held on with bailing wire, some of the cargo doors were held together with duct tape, and the instrument panel was held in place with safety pins, some which were not holding very well.

Sam enjoyed my apprehensive observations of the plane while our baggage was being loaded. Proudly, he told me the aircraft company we were using had the best record of non-accidents in the whole country. However, he also said the landing strip on the concession was quite small and hard to get into because of a large hill that had to be dropped over quickly in order to touch down at the beginning of the runway. In fact, he informed me the company had lost one of its planes trying to land on the concession during the week before. I asked if anyone was hurt. “All dead,” Sam responded, with a smile on his face. And he was serious! .

While, for proprietary reasons, I am not able to divulge the exact location where we were operating, I can say that we were at least several hundred miles into the jungle south of Ciudad Bolivar, towards the Brazilian border.

In this instance, we were asked to do this preliminary evaluation just as the rainy season was getting started. Shortly after taking off in the dual engine plane, we began seeing large rolling clouds. The further south we flew; the larger and more dense the clouds became.

About halfway to our destination, the pilot put down on a small landing strip in a relatively small village to pick up a full load of mining equipment which he had to leave there the day before. He had not been able to get out to the concession because of the almost zero visibility caused by the heavy rains and clouds. As we landed on this strip, the first thing we noticed was a completely wrecked plane that had crashed there. This added to our apprehension and to Sam’s sense of adventure.

It took about an hour to pack the airplane completely full of mining equipment. Since we had to remove the seats to make room for gear, Alley and I were directed to lay up on top of the gear that was stacked up in the belly of the plane. No seat belts! And the plane was loaded so heavily, even the pilot was not sure whether or not we were going to make it off the runway when we took off. We barely made it, and the plane was very sluggish to fly for the remainder of that trip.

We were in and out of clouds for the remainder of the flight, much of the time with zero visibility outside of the airplane. Occasionally, we would break through the clouds and see nothing but dense jungle below us as far as the eye could see in any direction. This was the Amazon! Sam took the time to educate us on the many different types of animals and insects which would certainly devour us if we were to have the bad fortune of crashing. Tigers and jaguars, driven out of some areas by villagers, only to be more hungry and ferocious in other areas. Six-foot long electric eels, called Trembladores by the natives, capable of electrocuting a man with 440 volts, and man-eating piranha were all through the rivers and streams, according to Sam. He told us of bushmaster snakes, the most dreaded vipers in all of South America. Sam said he personally had seen them up to twelve feet in length with a head about the size of a football. “Very aggressive–they have been known to chase a man down.” Sam said you could see the venom squirting out of the fangs even as the snake started to make a strike– one of the most horrifying experiences he had ever seen. “But, not to worry, I brought along a shotgun just in case we get in trouble,” Sam told us as hundreds of miles of jungle passed beneath us.

After quite some time, at a point when the clouds cleared away just long enough to see, Sam pointed down to a short runway cut out of the jungle. At first, we could not believe we truly were going to try and land there. Sure enough, it was the base camp for the concession. We made one low pass over it. The base camp looked large and well equipped. There was also a small local village right near the base camp. The landing strip was filled with puddles and looked to be mostly mud. Alley and I were a little nervous after Sam’s big buildup, and we had very good reason to be nervous.

In order to land on the strip properly, the pilot had to fly just over the treetops, around a ridge, to drop quickly over a hill almost into a dive to get low enough, fast enough, to meet the beginning of the runway. The pilot’s skill was very good, although it is the only time in my life I have ever been in a plane that actually tapped the tops of trees as it was going in for a landing. The thump, thump of the trees hitting the wheels of the plane put me in somewhat of a panic. But it was all for nothing, because within seconds we were safely down on the runway. The pilot and Sam seemed to think nothing of the hair-raising landing experience. Alley and I felt like cheering that we were still alive. This was the mental state we were in when we arrived in the jungle. And it was just the beginning!

Local villagers came out to help us unload the plane. They all seemed like very nice people. After having a chance to load our gear into the bungalow, Sam gave us a short tour of the base camp. The whole area was fenced in. There were numerous screened-in bungalows for the various crew member sleeping quarters, a large kitchen, an office, and a large screened-in workshop area. The company had spent a lot of money getting it all set up. There was a jeep and two off-road motorcycles—all in a poor state of repair. They operated, but without any brakes.

After we had a chance to relax a bit, Sam insisted we go meet the “Capitan,” who was the chief of the local village. We had to arrange for several boats and a small group of local Indians to support our operation along the river. Sam explained to us that public relations were very important and that we must go over and have a friendly drink with the Capitan. We assumed Sam was bringing the Capitan a bottle of Scotch or Brandy or something as a gift. But that’s not the way it happened. Sam preferred to drink the local mild alcoholic beverage called Cochili. This drink is made by the local Indians from squeezing the juice out of a special plant that they grow. The juice is allowed to ferment in the open air for several days or weeks, depending upon the weather. It is a milky white-like substance with clumps of bread-like soggy goo (kind of like pollywog eggs), along with some greenish-brown mold mixed in–it was great to behold! It smelled almost as bad as it looked.

We met the chief, who looked totally wasted on something–probably the Cochili drink. And immediately upon our arrival, the chief ordered some children to bring glasses and drink for everyone. Promptly, our glasses were filled to the rims. Sam quickly downed his first glass, licked his lips, smiled and said, “This is all in the name of good local public relations!” To be polite, I downed half my glass and did my best to choke back my gag. The stuff tasted terrible! I realized my mistake right away when one of the kids immediately took my glass and refilled it to the brim. Alley was paying close attention and slowly sipped his drink, and I followed suit. There was no place to spit if out without being seen, so we had to drink it down. Sam put down three or four more glasses and shortly was slurring his Spanish in final negotiations with the chief. I’m not really sure they understood each other concerning any of the details, but everyone seemed happy with the negotiation.

It was a good thing that the rainy season prevented the remainder of our mining equipment to arrive in the jungle for the next two days. Because I spent the next few days with a severe case of the jungle blues. I was popping Lomotil tablets left and right to try and dry up my system and finally started making progress on the third day in the jungle. Man was I sick!

Alan boasted that he never had a case of diarrhea in his life and that he never would. Sam spent several hours every evening drinking Cochili with the local Indians who would accompany us into the jungle. He was getting to know them better.

The weather was hot and muggy, although the heavy rains had not started yet in earnest. The jungle was alive, especially at night when the jungle noises were almost deafening. It was certainly not a nice place to go for a friendly, evening hike. We were glad for the fence that surrounded the compound.

On the third day, still weak from the fever, but feeling like I should be productive at something, I decided to take a motorcycle ride on the new jeep trail which had recently been hand-cut several miles to the river. Why is it that I always know when I am going to come upon a nasty snake just an instant before I see it? As I rounded the first corner on the trail, a large viper took off ahead of me up the trail faster than a man could run. No brakes! Finally, I stopped the bike, turned around, and returned to camp to rest up some more.

“Once the rains started, the water was so muddy we had zero visibility underwater and had to find our way through the broken branches of submerged trees by feel”

The remainder of our gear finally arrived on the following day. We assembled everything to make sure it was all there. It wasn’t. We were missing the assembly bolts for the six-inch dredge; we had only one weight belt; and we had no air reserve tank for the hookah system! This was not good!

We finally ended up using bailing wire to hold the dredge together, and had to settle for hooking the airline directly to the dredge’s air compressor. One weight belt was all we were going to get—not much margin for error! The entire operation would depend upon us not losing that single weight belt.

On the following day, all the equipment was packed to the river by the local villagers. This was not an easy two-mile pack, because the trail was very muddy and was quite steep up and down the whole distance. Alan and I were using one of the motorcycles to get up and down the trail, which was a real adventure with no brakes.

One very interesting thing about this jungle is that huge trees, for no apparent reason at all, come crashing down. At least several times a day, we would hear huge trees crashing down in a deafening roar. On one occasion, Alan and I were returning to base camp on the jeep trail. We had just come up that trail fifteen minutes before. As we were going down a muddy hill and rounding a bend, we ran smack right into a huge tree which had just fallen across the trail. Good thing I was driving! We smashed into the tree with both of us flying off the bike. Luckily, neither of us were hurt more than just a few bumps and bruises, although the front-end of the motorcycle was damaged. Chalk up one more for the jungle.

During the time while equipment was being transferred to the river and set up, we took several airplane rides to survey the section of river which we were planning to sample, and to make arrangements at a small village (with a landing strip) about twenty-five miles downstream to obtain fuel and some basic supplies as needed during our sampling trip. Once we started, we would not be in contact with the base camp until our sampling project was complete–which was to be about twenty-five to thirty days later. In flying around the area and landing on the two strips, it soon became apparent that the pilot was very skilled. While he definitely was flying by the seat of his pants, the conditions were normal and it was no big thing (to him). Sam just had the advantage of prior experiences at the concession and was psyching us out–all in fun. It only took a little while to catch onto his game.

One of the things we quickly learned in the South American jungle, is that you never stand still for more than just a few seconds. Otherwise, a steady line of ants, mites, and other meat-eating critters will crawl up your legs, inside or outside your pants, and go to work on you. We had plenty of mite bites–which hurt, itch, and generally drive you crazy for about five or six days before they start healing. And, we learned to never brush up against bushes as long as we could help it, for fear of getting fire ants all over us. They sting like crazy!

We never allowed our bare skin (especially bare feet) to come in contact with the bare ground in or around the camps. This is because of chiggers. Ants were everywhere. Whole armies of big ants could be seen to follow a single file line up and down the trail for a mile or more, carrying torn up leaves from a tree which was actively being stripped clean by other ants. The whole jungle was crawling with life. Every square inch had some creature that was starving to take a good bite out of us. Perhaps it was the muggy weather, or maybe weakness from the jungle fever, but my first impression of the South American jungle was that it was doing everything it could to suck the life energy out of my body.

On more than one occasion, some huge animal would go crashing through the jungle just a short distance from where we were standing. We never saw the animals, but had the continuous feeling that some huge cat or wild boar was ready to come smashing in on us. And, of course, the shotgun was never in my own hands when this occurred, which was probably a good thing for everyone else in the vicinity.

“We allowed the natives to swim in the river first to make sure there were not going to be problems with piranha and Trembladores”

While we were packing gear, one of the village-helpers came running in to show off a bird spider he had caught and skewered on the end of his machete. This spider was bigger than my hand; it looked like a huge tarantula. According to the natives, these fearsome spiders catch birds to feed on, not flies, in their webs.

Our first few days on the river were absolutely, breathtakingly, exotically beautiful. The sun came out. The river was low and semi-clear. The water was warm, but just cool enough to give us satisfaction from the muggy air temperatures. We did not need wetsuits other than to protect our bodies from scrapes and bruises. We dredged a half dozen or so easy sample holes. Gravel was shallow to bedrock. The first camp was quite comfortable. The Indians were using their bows and extra long arrows to catch great-tasting fish. Everything was perfect. I remember wondering why I had such a problem adapting to the jungle in the first place. It was like paradise on the river, and we were even getting paid to be there!

We allowed the natives to swim in the river first, to make sure there were not going to be problems with piranha and Trembladores. This is not a bad thing to do. We did not make them swim first. They simply dove in. We always watch for this in a jungle environment. The local Indians know what it is safe to do. After watching the Indians swim for quite some time, we decided it was safe.

The natives live under grass roof shelters–often with no sides. They hang hammocks from the supporting roof beams and sleep at least several feet off the ground. Since Ally and I don’t sleep very well in hammocks, we brought along cots, instead. On our first night in the jungle, Sam insisted the cots would be just fine on the ground. They had short legs which put the cots about six inches off the ground. Alan and I both had sleeping bags which could be zipped up. Sam simply had one dirty white sheet. About midway through the night, Sam’s cot collapsed on him. Shortly thereafter, he was dancing around the camp yelling, “Fleas!” He was barefooted, and the natives spent the next two weeks picking chigger eggs out of the bottom of his feet with sharp pointed sticks.

Let me explain chigger eggs: These critters somehow lay eggs inside the pores of your skin. The eggs grow larger and larger, causing an open sore. It keeps getting worse until you realize it is not just a mite bite. The egg has to be removed with a sharp piece of wood, kind of like a toothpick. The eggs I saw were about the size of a soft, white BB when removed. It was explained that this was really a sack full of eggs. The trick was to get rid of them before the sack broke. Otherwise, the problem was severely compounded. Apparently, the dogs carried these chiggers all over themselves. We were instructed to not pat the dogs for this reason. It was a good lesson for us, and we learned it quickly from Sam’s experience.

We had a three hundred-foot roll of half-inch nylon rope with us for the mining operation. The following day, Alley and I allocated one hundred and fifty feet of that rope to be used to tie our cots up into the shelter beams to keep us well away from the ground. Our Indian guides were quite amused by this. The rest of the rope was used in the dredging operation.

On about the fourth day on the river, Sam returned to the base camp to supervise the other surface digging testing operations. Our cook became extremely angry soon after Sam left. I later found out that he was contracted by Sam to spend only five days in the jungle. Sam left without taking him along. He was stuck with us in the jungle for the next twenty days or so, and we all paid for his anger in the food he prepared for us. We would get fresh-made pan-fried bread every morning that was so saturated with oil that you could squeeze the oil out of it in your hand. This, along with a can of sardines for breakfast. We got leftover bread from breakfast for lunch, along with more sardines. We also got sardines with stale bread for dinner. The cook was basically on strike. Luckily, there were plenty of banana and mango trees along the river to supplement our diet.

“It was easy to follow the tributary because it was running straight black mud”

But we had our attention on other matters. The heavy rains began on the day Sam departed. In one night, the river rose up at least fifteen feet. And it roared! Entire trees were washing downriver. It was a torrent. The water was the color of brown mud. The river rose up and spread out into the jungle, making the whole area into a huge, forested lake. There were no riverbanks to be found in most areas. Our own camp was within four feet of being washed away. We knew where the river was only because of the swift moving water. Some of the river was difficult to travel upon, because it was flowing through the treetop canopy, which was occupied here and there by huge nests of African killer bees and other hornets and varmints. It was a nightmare!

On top of that, the natives caught a hundred-pound Cayman (alligator) with a net out of one of our dredge holes where they had been fishing. It was certainly big enough to take a man’s arm off. At that point, the natives told us these animals came much larger on the river.

That was the day Alley decided to come down with his own bout of jungle fever.

Since Alley was incapacitated, I chose that day to hike back to the base camp and have a talk with Sam about the adverse diving conditions. Although we had recovered some diamonds and gold already, I was not comfortable with the recovery system for diamond recovery. I also was not excited about diving in the swollen, muddy river. I would like to get a look at what is going to eat me before I die! Even the natives, who were standing in line to dive in the clear water, absolutely refused to dive in the river once the rains started. This was definitely a very bad sign. Sam managed to get the big boss on the radio and I explained the problems to him. In turn, he told me that his entire company was depending upon the results of my sampling project to justify further investment in the project once the rainy season tapered off. “It all depends on you, Dave.” I told him we would do the best that we could.

The next day, Alan was so weak from diarrhea, that he was barely able to get out of his cot to do his duty outside of camp. I felt my own duty was to go do some sampling with the help of two natives as my tenders. Rather than dredge on the main river (which was raging), I decided to test one of the main tributaries which had the reputation of having lots of diamonds. The natives left me to keep an eye on the dredge, which was tied to the canopy of some trees at the mouth of this tributary, while they hacked a trail through the tree branches several hundred yards up this creek–which was now an endless lake out into the jungle. It took several hours for them to make the trail with their machetes. It was easy to follow the tributary because it was flowing straight, black mud, compared to the brown color of the river water.

While I was standing on the dredge waiting for the natives to finish the trail, a huge bee buzzed by my head. Within a couple minutes, there were about a dozen of these bees buzzing me. They were really mean! I had my hat off and was flailing around wildly trying to keep them away. There was no place I could go off to, to get away from them. Finally, I had to jump into the water and hide underneath the sluice box. This is where the natives found me when they returned. They were quite amused.

It took quite some time for us to drag the dredge up this tributary, because the branches were just hacked off at water level. I was looking for a place we could work off of a streambank, but eventually gave up on that idea. The water was simply too deep. I ended up throwing the suction hose over the side of the dredge, primed and started the pump, put on my seventy-pound lead weight belt and other diving gear, crawled over the side and shimmied carefully down the thirty-foot suction hose. The problem was feeling my way down through the submerged tree limbs to find bottom. There were logs and branches everywhere. I was in total darkness–complete zero visibility. Everything was done by feel, sensation and yes, fear. I finally found the bottom and estimated it to be about twenty-five feet deep by the amount of suction hose I had remaining with me on the bottom. It was scary down there!

After seeing the Cayman on the day before, I had visions of being grabbed by a huge alligator, and other visions of being grabbed by a huge python. A strong voice from inside my heart was telling me to end the dive. It was too darn dangerous! Any emergency would have me and my airline all tangled in the branches. Having to dump the weight belt would put an end to the entire program, because we only had one weight belt.

I decided that I should complete the sample after all we had gone through to get me on the bottom. This is what I was being paid to do.

As I dredged into the gravels on the bottom, by feel, I discovered more buried branches and logs. These, I simply tossed behind me just like I do with oversized rocks. I got into a pretty steady routine down there and was making good progress. But the strong picture of huge alligators and pythons was right there with me all the time. Do you know the feeling you have when watching a scary movie when you know something terrible is just about to happen? And when it happens suddenly it scares the heck out of you? This was the state I was in when something heavy jumped onto my back. I let go of the hose, turned on my back, and kicked this thing off of me like a crazy man–like I was fighting off an alligator. Then I realized it was just one of the water-logged heavy pieces of wood I had thrown behind me.

This was a terrible feeling of terror and embarrassment. I’m serious; I was so scared, I wanted to crawl right back up into my mother’s womb. I was left wondering what the heck I was doing there. Why was I doing this? It was nuts!

It is impossibly-difficult times like this, and how you manage them, that contribute to the definition of your personal character and integrity. And I freely admit that staying down there to finish the sample was one of the most difficult challenges I have ever overcome. This was a total mission-impossible situation! After a moment to get myself refocused, I turned around and finished the sample hole to bedrock. I carefully shimmied back up the suction hose, coiling my airline as I went, to make sure it was not tangled in branches. When we cleaned up the sluice boxes, we were rewarded with several gem-quality diamonds, one which was quite large and handsome.

“I let go of the hose, turned on my back, and kicked this thing off of me like a crazy man!”

When I got back to camp that night, Alan was still sick in his cot. I did not hesitate to tell him of my experience. I also told him he was doing half the diving from then on, starting the next day, with or without jungle fever!

And that’s the way it went for the next twenty days or so. We completed four samples per day, with Alan doing half of the diving. Some days, the river was so high we had to tie off on branches of trees out in the middle of the river. We would take turns watching for trees being washed down the river, and would pull each other out by the airline every time this occurred, to keep from getting snagged by the trees and dragged down river.

The diving was extremely dangerous. Each time one of us went down, we did so knowing there was a definite possibility that we would not live through it. The only other option was to give up. But, we had originally agreed to do our best to overcome the difficult conditions. That’s how we got the job in the first place. We didn’t really have any other choice. I look back on it now and can enjoy the adventure. At the time, however, it was not any fun at all. It was crazy!

The biggest problem was the lack of an air reserve tank on the dredge. Sometimes it would take as much as ten minutes to feel a way down through the submerged branches in the total darkness. We had to find a path. There was no easy, fast way to get back to the surface. Cutting the weight belt loose would probably be sure death. Not only that, but we would probably never recover the body! No reserve air tank meant almost no margin should the engine quit for any reason–which, luckily, it never did.

However, the heat from the compressor did melt the airline, causing it to blow off altogether when I was down on one dive. We run the airline around our neck and through our belt for safety. With no air reserve tank, we were able to hear the compressor working underwater by the vibrational sounds coming from the airline. I had just spent quite some time finding a path to the river bottom and started dredging gravel, when my air supply was abruptly cut off and I no longer heard the compressor noise from the airline. But the nozzle was still sucking. I stayed there for a few seconds trying to understand the problem and what to do, when suddenly my air supply returned and I heard the compressor noise again. I almost just kept on dredging, but decided after all to go up and see what had happened. When I got to the surface, Alan was holding the airline onto the compressor output with his bare hand. He got a pretty good burn out of it. An inexperienced underwater miner never would have known what to do. Alley saved my life. This is one of the reasons I seldom do these projects alone.

“He made his bow out of the core of a hardwood tree, using a machete to carve it exactly the way he wanted”

As we progressed with our sampling further down the river, the natives would move all the gear to new camps every three or four days. Some camps would be reconstructed out of already-existing structures. Other camps had to be built from scratch, using plastic sheeting for the roofing material.

Our main native guide was named Emilio. He was a real jungle man in every sense of the word. He walked with a limp because of an earlier airplane crash in which he was the sole survivor. His family hut had been hit by lightning several years before, and everyone in the hut was killed except Emilio. He was a real survivor! One night, he went hunting with our shotgun–which was only loaded with a single round of light bird shot. In the darkness of the jungle at three o’clock in the morning, Emilio snuck right up on a five-hundred pound female wild boar and shot it dead–right in the head. We had good meat for several days, and even the disgruntled cook cooperated with some excellent meals.

Emilio taught us how to hunt with bow and arrows–mainly for fish. But, he was able to bring in a few chicken-like birds on several occasions. The meat was tough and stringy, but that was probably because of the cook. He made his bow out of the core of a hardwood tree, using a machete to carve it exactly the way he wanted. The arrows were made from the same hard material, using poison from snake venom on the tips for big game hunting. The natives did not have any modem weapons whatsoever, other than the shotgun we let them use while we were there.

Even Emilio refused to dive during the rains. And, our doing so considerably raised the natives’ evaluation of our physical abilities and bravery, even if we were greenhorns in the way of the jungle.

Each Indian we met was very skilled and uncanny in jungle survival. They could tell a boat was coming up the river three hours before it arrived by hearing the change in bird sounds. You will never find a harder bunch of workers anywhere.

The canoes we used were also carved
out of the trunks of hardwood trees. A skilled native takes about six months to make a good dugout canoe, which sells for about sixty dollars. Mostly, the canoes are paddled. But the more affluent natives do have outboard motors, which make the canoes go along at a pretty good clip. The natives are very skilled at driving the

canoes over top of submerged logs and through rapids. A lot of the time the boats were loaded so heavily that there was only about a half-inch of freeboard on each side. Yet, we never swamped a boat.

The gold pans they used, called Beteas, are also carved out of huge logs. Several classifications of screens are used on top of the Beteas to classify material and screen for diamonds. The natives have a special way to quickly rotate the screens, which causes diamonds to move to the center of the screen where they are easily picked out. It is quite something to watch.

Many native miners only go after the diamonds. They know they only need to find about one or two diamonds a year to make it worth their while for the extra things they want. Otherwise, the jungle provides for all of the basic survival needs of the natives. They are quite self sufficient.

“I was running down the trail at full speed like a mad man out of control, swinging my hat about

The natives received about two dollars a day in wages and were happy to get it up until the end of our project. We wanted to extend one more week to really finish the job right. However, the natives made it clear that no amount of money could sway them from going back to harvest their gardens on time.

While we were hauling our gear along the mile and a half-long trail to the landing strip, I was swarmed by African killer bees. It was terrifying! I heard them coming from quite some distance away. It sounded like a bus coming through the jungle. First, there were only a few bees around me, then a whole bunch. In panic, I was running down the trail at full speed like a mad man out of control, swinging my hat about. Then they were gone. I put my hat back on only to get stung right on top of the head. I felt completely spent. It was time to go home.

When we returned to the base camp, we found out Sam had plenty of problems of his own. At least half his sampling crew had to be evacuated from the jungle due to an outbreak of malaria and yellow fever. When we arrived, he immediately needed our help to Griphoist the jeep out of a creek that it had crashed into. Apparently, the jeep had a problem jumping out of first gear while being driven down a hill. The lower gears needed to be used to keep the jeep from going too fast, because of the no-brakes situation. Sam was driving the jeep down a steep hill with four natives in the back. It popped out of gear and they made one mad roller-coaster ride to the bottom, only to smash right through their man-made bridge into the creek. Miraculously, no one was hurt and the jeep wasn’t wrecked. We managed to get the jeep back onto the trail and hightail it back to the base camp just as total darkness descended on the jungle. Sam looked at it as just another great adventure; just another day in the life of a jungle-man!

Our trip back from the jungle to Caracas was relatively uneventful, except that I was able to buy a nicely-cut diamond in Cuidad Bolivar for pennies on the dollar at U.S. prices. I presented this to my (ex) wife when I returned home and she was quite pleased to have it mounted on a ring.

Over all, our project was successful. We found diamonds, and we found some gold. We did exceptionally well considering the impossible conditions. The largest diamond located on the concession while we were there was over eight carats. But that came out of one of the test pits on Sam’s digging operation. We never found gravels deeper than three feet to bedrock, and there was very little oversized material to move by hand–other than submerged logs. The area would be a breeze to work in clear, slower water–like during the dry season. Everyone involved was impressed with our test results. We submitted a proposal to do a more extensive test/production project with more men and larger equipment, but internal politics within the company ultimately killed the program altogether.

I’ll say this: If we ever do go back, I guarantee it will not be during the rainy season. And we will have a cook who can find no better pleasure in life than to feed us well.

BY NANCY CRAGO

 

It is common knowledge that if one is both wealthy and strange, he or she is called eccentric. Most miners I have run across are not wealthy, but the word eccentric suits them very well.

There is a miner living in the Klamath National Forest who has four gnomes near his home. They are comfortably arranged in the fallen leaves under a majestic madrone tree. When it rains, it is difficult to distinguish the brightly colored ceramic gnomes from the brilliant orange bark of the tree. There is a legend that gnomes protect gold; and in this case, the array of possessions outside, too. Last winter, their bright red hats peeked out of the snow. Very close to them, next to the manzanita bush, was a life-size miner snowman kneeling with his gold pan and pick. What else would one expect at a miner’s home near Happy Camp?

This is only one example of the magical things I have seen since learning to view the world through miners’ eyes. The miners seem to blend right into the woods and rivers and are accepted by the creatures who live there. Could it be that the “eccentric” miners are better understood by the creatures of the woods than by their fellow “civilized” men?

Last summer, while dredging on the Klamath River, I met miner-Bob (miners rarely have last names). Bob was a great hulk of a man. He would always chat a bit when passing by on the trail on his way down river. When asked when he would be coming back after work, he would say, “That depends on when the black bears want their dinner — nothing should keep a man or bear from his food.”

It seems this man would work until dusk when he saw the black bears coming from across the river to eat their evening meal. Because the forest was so dense on the opposite side, few berries and apple trees grew there. But on our side, the wild blackberry bushes were everywhere with berries as big as your thumb. It was touching to think this man, wearing a custom-made wet suit, size XXXLarge, would respect a bear’s dinner-time.

One evening in the same area, the bears came across the river and tore up the campsite of another miner while looking for their dinner. They ate all the fresh fruit, eggs and meat (except for the bologna) and other packaged sandwich meat. They also left the white bread. Perhaps we can learn something from these bears!

As one drives west along the beautiful, wild and scenic Klamath River road, Highway 96, one eventually comes to the Dillon Creek area. Near this area is an old highway no longer maintained. This road, with weeds growing in the middle of it, wraps around the mountains. It ends abruptly at a bridge abutment left useless by the 1964 flood.

The area is much loved by the osprey, who build their nests on the broken off tops of dead trees, called snags. An old grizzled miner friend of mine went up that road on Sunday. He said, “It’s better than going to church for me, I can talk to God and his creatures up there.”

He told me as he was walking along the road in an unhurried fashion, an osprey suddenly flew from his nest and began calling to him. As the miner looked up, he thought, “What a magnificent creature you are and what beautiful feathers you have.” He was trying to imagine the view the bird would have 300 feet above the river. The miner’s view was almost overwhelming in its beauty, and he was only 100 feet or so above the river. With that, the bird continued to call the miner, flapped its wings with great force and seemed to stop in midair. From the bird, a perfect feather fell landing near where the miner stood. The feather is carefully and lovingly displayed in the miner’s home as a memento. He says it is a gift from “one of God’s creatures.”

A novice lady-miner friend of mine wanted a nugget for her husband’s birthday present. He had never dredged one up. Not having a great deal of extra money available, she decided the best way to get one was for her husband to dredge it up. When she and her husband set out that day toward their dredge on the river, she commented she just knew he would find something special that day. As the lady stood in the river tending the dredge, a Monarch butterfly flew near her head and landed on her wide brimmed straw hat. It made no attempt to flyaway.

She remembered a local Karuk Indian saying that butterflies are the communicators for the animals, and they will bring good luck. A short while later, she walked around the triple sluice box of the dredge and there in the second riffle from the bottom in the center box lay an exquisite 22-grain nugget. She thought immediately about what a third generation old miner, Allan Copp, said in his book, “The native nugget you find in a river is unique; it is one of its kind in all of creation, and no other human hand has ever touched it…don’t sell it.”

If you want to know where someone has “punched a hole” in the river, just follow the schools of happy little fish. They fill the Klamath River, especially during the summer months. As the dredgers displace rocks in different areas along the river-bottom, word quickly spreads in the fish community. No sooner has a rock been shifted than the little fish are there to gobble up the algae and other food growing on the rocks.

Another creature who loves the dredges is the lamprey eel. They hang out in a dredger’s hole during the evening. Because of the lack of current in the hole, this is an ideal spot for them to rest. Most dredgers, when they go to work in the morning, are surprised to see the long slender snake-like body in their “office”, as one miner refers to his hole.

Steelhead and salmon prefer spending time in dredge holes because the water is much cooler and deeper, and they can rest for a while before continuing their swim upriver to their spawning grounds where they were born. Cobbles and boulders piled up in the rear of a dredge hole create hiding spots where trout and salmon can rest in comfort from predators. These holes are quickly filled in by the first fall storm, and the tailing piles are leveled out. The soft pack remaining is a nice home for the Crayfish.

If one were to ask a miner about an Entosphenus tridentatus or an Ocorhynhus Kisutch or a Salmo Gairdneri, he would probably not be able to tell you these are a Pacific Lamprey, a Silver Salmon or a Steelhead Rainbow Trout in that order. Nevertheless, there is a working arrangement between the miner and the creatures of the river.

Perhaps the least welcomed by lady miners are the water snakes. They, too, tend to gather near the miners working near the bank, looking for food. I noticed the numbers grew during the summer months — again the word was out — food! Miners are not the type of people who make a big deal out of what they do — except when they find a good pay-streak. If they notice something that needs to be attended to, they do so — usually quietly.

A miner I met last year noticed the highway was littered with pop cans and trash. He mentioned this to a few buddies, and one bright sunny day 40 miners quietly picked up 20 miles of trash, loaded it into their pickup trucks, and took it to the dump. They were not paid by anyone. They did it because they wanted to and “it needed to be done,” said the miner who arranged it.

A mining couple who are friends with friendly smiles and shiny eyes volunteered a story to me. They returned to their campsite one cold evening a little discouraged from their day of sluice-mining. There on the top of their tent sat a fluffy owl peering through the darkness. They considered this a gift and positive omen of abundance. It was!

There are thousands of miners who flock to the river and creeks to enjoy, not destroy. They come to see their trees and to breathe the fresh air and to sleep under the stars. They come to see the wild mallards and the black-tail deer and the otter play. They come to share a mining experience with people they never met, and end up being partners before the season is over.

As one small-scale miner said, “I never knew how proud I was to be an American until I saw an American bald eagle fly up the river at dusk. I stood there and cried at its great strength and beauty and realized these freedoms are slowly being taken away from the miner and the American people.”

 

BY DON PADGETT

During my fourteen years of mining throughout the United States, with a variety of gold mining equipment, I’ve seen and processed a lot of black sand. And since the mining equipment I’ve used has ranged in size from gold pans and suction dredges to Caterpillars and heavy equipment, its been possible to approach “fine placer gold recovery” and its liberation from black and blonde sands from virtually every level.

Learning in any form takes time and usually a lot of practice, which all too often includes making a few mistakes. So I might as well begin this article by admitting that I’ve certainly left my share of gold on the ground, even after all the hard work of getting it out of some of nature’s most elusive hiding places.

Liberating gold from black sand can be a very difficult process, especially when the gold is extremely fine. The finer the gold, the more difficult the recovery seems to be. And whether you’re an experienced miner or a novice, it is certainly a waste to walk away from your fine gold, leaving it half processed in a pile of black and blonde’ sands at your clean-up site along the river bank or in your campground. For example, let me relate a true story of one of my own recent experiences:

During a recent winter, after a fairly good dredging season, the cold water and my own curiosity caused me to wander around and check out some of the black sand piles (left behind by other miners) I had noticed earlier in the season. Knowing from my own experiences how miners tend to lose gold during clean-up, I took along my gold pan to test with; and sure enough, in the first pile of sand I found two nuggets (about 1/4 and ½-pennyweight) along with plenty of color. I immediately went back to camp and returned shortly with my shovel and some buckets which I used to transport the heavy black sands back to my campsite where I do my own clean-ups. I use an industrial-type spiral-wheel which is larger and faster than the typical gold wheel sold in most mining supply stores. Gold wheels will do a great job of fine gold recovery providing they are set up and used properly. And since every wheel and concentrate deposit is unique, your ability to tune your wheel and work your sands will be the critical factors affecting your fine gold recovery, not a particular brand name.

During the past few months, I’ve also been running the final clean-ups from a number of mining operations along the Klamath River in northern California. In most cases what were only five gallon buckets of “previously processed” black sands magically changed within a few hours into literally pennyweights and ounces of liberated fine gold. You can just imagine the surprise and excitement experienced by these dredge operators when they saw that the black sand byproduct they had so very often considered “nearly worthless” or “unrecoverable” was in fact valuable and could even pay a substantial portion of their operating expenses.

Most of what I’ve learned was to a large extent the result of associating with some of the best clean-up men in the gold mining fields of Alaska. They had been liberating gold for more than fifty years when I first met them, and many are probably still at it today. If there is a single and most important key to unlocking the mysteries of fine gold recovery, it is “the basics always work.” So if you’re in fine gold, and you’re not able to recover it, remember to return to the basics.

What follows is a simple step-by-step process of the basics of fine gold recovery:

Without Classification, Liberation is not Possible

Virtually every piece of modern mining equipment currently available in local mining and equipment shops has its own inherent system of material classification. To classify, in mining terminology, simply means to separate the material (rocks, gold, and sand) by size and/or weight (usually by size). It only makes sense to take this process even further in handling the clean up of your concentrates.

Classification is often accomplished by using screens of various sizes or meshes, and while many gold miners choose to buy these screens from their gold mining supply store, it is not unusual at all to see lint screens, window screens, and even kitchen sifters alongside a clean-up operation. Classification screens come in many sizes: 4, 8, 12, 20, 30, 50, 100, and even smaller. These numbers represent the number of openings per linear inch. For example, a 4-mesh screen has four holes per linear inch or 16 holes per square inch, and allows material to drop through which is smaller in size than about 1/4 inch smaller, actually, because the wire in the screen takes up some of the space.

With a little practice and experimentation you will find out which screen will work the best for you and your particular clean-up operation.

Beginning Your Clean-Up

Start your clean-up by removing your concentrates from your sluice box. Next, use your #4 screen to classify and remove this spectrum of material, checking closely for nuggets and large, flat flakes. Surprisingly, many miners fail to inspect closely because they are working a deposit that only seems to produce fine gold. Nuggets can be lost because they are simply thrown out in this important stage of the process. Usually this first step is done right at the river bank, making what you must carry back to your camp less cumbersome. Now screen your materials though your #8 screen. What’s left on top of this screen will be easy and quick to pan at the river. Take what falls through the screen back to your wheel for processing.

Using Your Wheel

It is very important to go through the above steps before attempting to use your wheel to process your concentrates. Remember, the wheel works on the principles of weight, angle (pitch), and water-flow. In the following steps, you’ll be first separating the blonde sands from the heavier black sands. This process is called the “first split.”

This separation should be done using your wheel’s fastest speed if you have a variable speed wheel. This split will take a little time, but remember that if you were panning this material it would probably take as much time or more, and may not be as effective for fine gold recovery. Many people purchase a wheel to reduce the amount of panning time in their clean-up operation, as well as recovering more gold.

At this stage, you’ll want to pull the black sands and gold from the blonde sands. It’s okay if a small portion of the blondes are drawn up along with the blacks in this first split.

We have found that skimming the lighter sands off the top of the material being processed in the wheel (not in the riffles) can be more effective than allowing the tailings to simply run out of the wheel with excess water.

The best demonstration of how to use a gold wheel that I have ever seen is in Dave McCracken’s video, “Modern Gold Mining Techniques.

When running this first split, the wheel will pack just like the riffles of a dredge. When this occurs, for better results, you can spoon material from the bottom of the wheel up onto the riffles. We also seem to get better results by spooning material onto the drier section of the wheel so that it passes into the flow of water as the wheel turns. Watch yourself very closely because this is the step where many of the larger flat flakes are lost simply by scooping the material out of the wheel too soon. Once this split is complete, you should find that you have cut your material in half or more.

Now you should have what we call salt and pepper sand and gold. If you have only black sands at this point, you have probably lost some of the finer gold already. Look closely; and if this is the case, stop, back up and rerun this split again. Remember, the wheel will only recover as well as the skill of the operator permits. So take your time and make sure you’re not losing your fines at each stage of the process.

Next, classify the remaining concentrates once more using a #12 screen. This time you’ll only have half as much material so it will go very fast. The material on top of the screen produces your bigger gold; and if you’re in good gold, you’ll be able to still see it lying all over the surface of the screen. Sometimes, I find it easier to dry and run a magnet through the sands. This approach will usually remove 50% to 80% of the magnetic black sands, leaving your gold and just a little material to pan or blow off. These gold particles and flakes should be bright and beautiful and can be put in your gold jar.

Now it’s time to tackle the material that dropped though the #12 screen by running it through the wheel. When using a variable speed wheel, this split should be processed at the slowest speed, and the pitch of the wheel should be set at a steeper angle. Use a moderate-to-slow water flow, adjusting the wheel to pull just a little black sand, and all the gold. Once you’ve run it through, simply adjust the wheel a bit steeper and rerun this gold-laden material once more, only this time just pull the gold.

This process will leave you with all your gold, and perhaps just a very small amount of fine black sand. I find that if you dry this final product, it is very easy to blow the remaining black sand of by sorting through it on a clean piece of paper and blowing gently. It is a nice way to end your day!

And finally, if you’re having any trouble in your clean-ups, remember to return to the basics by watching your classifications, checking what you’re about to discard on a regular basis, and by making sure that you’re not leaving your fine gold for someone else to recover simply by re-running your old sand piles. I hope these hints are helpful, and good luck with your future clean-ups.

How to Determine what “Good Gold” Means to You

 

Damp soilThe meaning of “Good Gold” is a matter of perspective and experience. This phrase is generally used in terms of quantity and ease of extraction. A couple of old-timers, sitting around the fire talking gold, will often have enough shared-experiences to know what the other means by “good.”

“This soil is very damp.”

The captivating nature of gold brings out different emotional responses from each of us.

The problem lies in the fact that just about every novice miner starts with little or no knowledge of the realities in the activity of gold prospecting. Our story may serve to shed some light on what to expect from your own first few mining trips.

Jean and I live in San Diego. To start with, our part of the country is very dry. So, a lot of the gold hunting is accomplished using a dry-washer. There are a few placer areas within an hour’s drive of our house, but they have very limited access and the gold tends to be pretty sparse. We tried some gold panning and found a few specks of gold; but from what we could determine from the local prospector’s club and friends, the Pot Holes would be a better-than-average place to start. This area is about a three-hour drive from San Diego, and is near Yuma, Arizona, but still in California.

Dry-washerBuilding a workable dry-washer would be a snap. I have always been good at figuring out how machines work and how they should be constructed. Ten minutes with a friends’ bellows dry-washer was enough to get me started on our own machine. A few days later, we were packed and driving to the desert with our newly-built dry-washer and an old 3-horsepower Briggs and Stratton engine. I just had to test my new creation. When it comes to gold, to me, now is always better than later.

Our maps were good, so we had no trouble finding the bridge across the American Canal along with the road to the open recreational mining area just southwest of the old 3 C’s mine. The road in had a few rough spots, but nothing that our little Vega station wagon (with three-inch ground clearance) could not make. By the way, this location still remains open to anyone; and to this day, it is still productive.

The big problem was where to start. Book gold is a lot different than real gold. The books we read were small and the maps and locations where gold would be trapped seemed fairly straight forward. The Pot Holes was huge; and of course, we wanted to work in the best spots. We wanted to find some “Good Gold!” I had read several articles about the importance of prospecting and sampling before you decide to invest the bulk of your resources to any particular area.

Jean and I do argue on occasion; and as it turned out, picking-out our first dry-washing spot was a perfect time to disagree (Thirteen years later, so we can minimize disagreements, we now have two of almost all the equipment we use.). After about fifteen minutes, we jointly settled on a small wash. There were a few tree roots and some exposed bedrock to work. This wash was about a hundred yards from where we parked the car. After packing our gear to the site, we set the engine and dry-washer in place; with the engine upwind to keep it free from the dust generated by our dry-washer. Then, with the dry-washer delivering about 90 beats per minute (possibly a little fast for the conditions we were working), we proceeded to dig and feed gravel to the dry-washer for about a half-hour. We had brought along some water for the purpose, so we practically ran back to the Vega to pan our concentrates. Much to our surprise, we had almost no gold. We just had some small specks.

Our next spot was just down from where our first little wash emptied into a slightly larger dry-wash. The opposite bank looked good to me. There was some exposed bedrock, and the overburden was only about a foot deep. The digging was very easy; and after an hour, we decided once again to check our progress. I was impressed this time. There were lots of little flakes. Jean was not so favorably-disposed. It still looked like specks to her; and after a short time, it began to look that way to me, too. Another move seemed to be in order. We spent the next two and a half days moving from place to place, from specks of gold, to specks of gold.

Jean was getting a little frazzled, and I was getting more and more frustrated. I wanted to go back to the place that impressed me on the first day. The bank on the small wash gave up about 1 pennyweight (about l/20th of an ounce) of gold in an hour, even if they were only small specks. To us, it did not look like very much gold and I didn’t know if it was good or bad; but that spot seemed far better than the other places we had dry-washed during the past few days. I really wanted to go back.

Jean went back to camp to make lunch and I picked up the dry-washer, engine and the pick and shovel and started off to my spot. After about ten steps, I heard a rumble. My first thought was that it couldn’t be thunder, not here. A quick glance over to the west set me straight. Over my head, it was sunny and blue. A few miles away, it was dark, very dark. Even I knew that it was impossible to dry-wash in wet material.

The thunderstorm might move the other direction. But at worst, I would have a little time to work. I hobbled to my spot, carrying over 75 pounds of gear and equipment, and quickly set up the dry-washer and engine. If it was going to rain, then I was going to shovel as much material through the dry-washer as it would take. I worked hard as the storm crept closer. The first big drops of rain arrived about an hour later. Ten minutes after that, our dry-washing was finished for this trip. I had kept the riffle tray dry as I had been told. Dust and moisture in the riffle tray cloth create cement, and that combination will not pass air. No air means no gold; which in turn, means stretching a new cloth for the dry-washer.

Everything else was wet. We panned-out my concentrates, and our total gold for the trip filled a two-pennyweight vial and half of another. We had over 3 pennyweights, most which came in two hours of dry-washing at my spot. It still looked like specks, but there sure were a lot of them. Our problem was that we had no yardstick by which to judge “Good Gold.” Back home, we told some mining friends about our spot in some detail and about how we had done. We thought there might be some more gold there and we were going back in a couple of weeks, after things had dried out a bit. Our more-experienced friends were impressed when we showed them our gold from our very first prospecting trip.

If you have never dry-washed, you must remember that any moisture in the pay-dirt will make any dry-washer less efficient. An easy way to check for water-content is to squeeze a handful of your pay-dirt into a ball. Then open your hand. If the ball falls apart, the material is very dry. If the ball breaks into several smaller sections and tends to crumble, you are working with slightly-damp material. Most dry-washers will run this material, but the efficiency will be diminished somewhat. If the ball stays intact or breaks into two or three parts, the pay-dirt must be dried before running through the dry-washer. On a good day, most dry-washers will lose between 10% and 20% of the finer-sized gold which remains trapped in small dirt balls. They pass right through the machine!

When we got back to our spot three weeks later, the site had already been cleaned out. We did get a little more gold, but we later found out that a few of our more-experienced friends went in there before us and recovered about two ounces of gold during our absence. From that time forward, both Jean and I had a little better understanding of what the term “Good Gold” means!

To this day, I still have a hard time keeping my mouth shut when it comes to where we are working and what we are finding. Most gold prospectors that we meet find this an endearing, if not a foolish, trait to have. I am getting the idea that when it comes to gold, you have to be careful how you conduct your business affairs!

If you are just starting out, whether you are working on a river, stream or in the desert, or whether you are using a dry-washer, sluicing system or four-inch dredge, recovering a pennyweight of gold an hour is making “Good Gold.” Two-to-five pennyweights in a day’s work is fairly good for small equipment. I personally average a little over two pennyweights per day when I am sniping (finding gold with hand tools and a face mask) on my favorite rivers in the Mother Lode area.

Over the years, I have built over a hundred dry-washers, both the bellows and constant-air types. I have written books on the home-construction of small-scale mining equipment. Jean and I spend most of every summer looking for gold. More gold is always better than less gold; but to me, I feel I have done well if my final clean-up produces over two pennyweights in a day. This is my personal yardstick for how I am doing. The amount of gold we find is important, but we are also enjoying what we are doing.

Here is where you can buy a sample of natural gold.

It is nearly always important for a prospector to target his or her sampling efforts to reach the bottom of hard-packed streambeds.

Dave Mack

 

Successful mining in streambeds is generally accomplished in two steps: (1) prospecting and (2) production. This is true on any scale of operation. First, you need to find a gold deposit, usually a pay-streak. Once the deposit is located, then you can concentrate on a production program to recover the gold from the deposit.

Prospecting generally consists of digging or dredging sample-holes in different locations, then comparing the results of the different samples. Through trial and error, the positive signs are then followed into high-grade gold deposits.

In a waterway, the first effort should be to locate the common path along which most of the gold typically travels. Sampling is then performed along that path to find the pay-streaks. This system is thoroughly outlined in Gold Mining in the 21st Century, and Part 1 of Advanced Dredging Techniques.

Dave’s Books & Videos

The following video clip also demonstrates this very important principle:

When you are sampling, you should nearly always be looking for hard-packed streambed material. “Hard-pack” is created at the bottom of waterways during major flood-storms.

Generally, a winter storm, even a large winter storm, will not create enough turbulence and force within a river, creek or stream to redeposit the compacted streambeds that are already in place along the bottom.

Flood-storms of the magnitude to redeposit streambeds do not occur very often.

For example, on the Klamath River in northern California, where my own team dredging operations take place during the summer months, we believe the last time that a substantial amount of hard-packed streambed was formed was during the 1997 flood. An even larger storm took place in 1964. In many places, a 1964 flood-layer was laid down on top of a much older, harder-packed, virgin streambed — one formed perhaps thousands of years ago.

To give you an idea of the magnitude of storm that it takes to create hard-packed stream-beds, take a look at the following video sequence I captured just down river from Happy Camp during the flood of 1997:

So, it takes a major flood storm to move and lay down a hard-packed streambed. And, it takes a super-sized major flood storm to create enough force and turbulence in a river to break up ancient streambeds and redeposit them as newer hard-packed streambeds along the course of the waterway. This happens only very rarely.

The reason that hard-pack is important to a prospector is because gold nearly always concentrates at the bottom of hard-packed, flood layers. Therefore, it is nearly always important for a prospector to target his or her sampling efforts to reach the bottom of hard-packed streambeds.

The following video sequence shows exactly what hard-pack looks like. I captured this video during a Group Mining Project in a location where we were recovering a rich gold deposit from the bottom of an ancient streambed layer resting on bedrock:

Gold is about six times heavier, by volume, than the average weight of the sand, silt, and rocks that make up an average streambed. Because of this disparity in weight, when streambed material is being washed downriver during a major flood-storm, most of the gold will quickly work its way down to the bottom of the streambed material that is being carried along by the raging flood waters.

In the following video segment, watch how fast the gold penetrates average streambed material once it is placed into suspension. The second video segment provides a visual demonstration of this very important point:

Because the gold is so much heavier, it will work its way down along the river-channel more slowly than the other streambed materials. During major flood-storms, most of the gold moving in a waterway will be washed down across the bedrock, or across the surface of hard-packed streambed that is not being moved by the storm. At some point during the storm, gold becomes trapped out of the turbulent flow by dropping into irregularities, cracks and holes that are present along the surface over which it is traveling.

Placer Geology

As shown in the following video segment, other heavy materials, like lead and old iron objects, also travel and deposit in the same places as gold. These other materials can sometimes lead you right into a rich gold deposit:

Because of its enormous weight, gold also deposits much earlier during the course of the storm than the streambed material which eventually seats itself on top of a pay-streak. As the storm begins to taper off, and the water-forces begin to slow down, particles of gold will start dropping out of the flow. Along the path where most of the gold is traveling in the waterway, traces will be deposited, with more substantial pay-streaks forming within the larger, low-velocity areas. These gold deposits are being laid down even as the (much-lighter) rocks and gravel are still being washed down river with the storm flows. Streambeds form later in the storm, when the water-turbulence tapers off enough to allow the rocks, gravel, sand and silt to drop out of the flow and form a seated bed along the bottom (over top of the gold).

Streambed material that lies in on top of a pay-streak will nearly always be hard-packed. The reason for this is that if there is enough force and turbulence to move substantial amounts of gold in the waterway, then there is also enough force to create a naturally-formed streambed on top of the gold as the same storm tapers off.

How do natural streambeds form? First, the storm needs to be powerful enough to rip up the streambed material, put it into suspension, and wash it down the waterway. This process is similar to gravel washing through a sluice box, only on a much larger scale. During the later course of the storm, as the water-force and turbulence starts slowing down, natural obstructions or traps along the river-bottom will allow certain key rocks to become lodged or seated. An example might be a flat rock that drops into a bedrock indentation, with the forward edge of the rock pointing slightly downward into the flow. The water-current then holds the rock to the bottom. With this rock in place, new locations are formed for other rocks to become lodged. Smaller rocks, sand, gravel, and silt will fill every gap and crevice in a manner similar to the mortar used to cement layers of brick. More rocks then fall into place. More filler then packs the spaces created between the rocks, and the bed forms.

Hard-packed streambeds form mostly with the flat rocks lying horizontally and slightly tipped downward against the direction of the current. The way in which streambeds form during major flood storms leaves the bed-material seated and compacted together, much like a mechanical structure. In dredging, we call this structure “hard-pack.” Most of the gold in present waterways is covered over by hard-packed streambed. So it is very important to know what it is. The following video segment shows you exactly what to look for:

For substantial amounts of gold to move within a waterway, it requires a major flood-storm with enough power to blast up some of the pre-existing hard-packed streambeds. This is because most of the existing gold in the waterway is trapped below existing hard-packed streambeds.

It is the abrasive action of the streambed material (more like a huge band-saw), as it is being washed down along the bedrock during major flood-storms, that causes bedrock channels to cut deeper into the earth over geologic time. When such a storm tapers off, new hard-packed streambeds will form over top of the gold deposits.

“Loose-packed” material consists of sand, silt, rocks and gravel which possess little or no natural structural cohesiveness. When you dredge a hole down through loose streambed material, it keeps sliding in on you. Digging through loose-pack can be like trying to dig down through a pile of sand or gravel. The material keeps slipping into the hole. This makes for a much more difficult sample hole if the material runs deep.

Sometimes, loose material is resting on top of a hard-packed streambed and must be moved out of the way first, before the hard-pack can be properly sampled.

When you dredge a test hole through hard-pack, the streambed will generally hold up the wall surrounding the hole. In fact, many of the old-time operations tunneled underneath hard-pack. This was/is called “drift mining.” Sometimes they even tunneled directly under active rivers!

It is also important to be able to identify tailings. Tailings are easy to identify, as long as you understand how streambeds are mined. Tailings do not look either like hard-pack or loose streambed material.

When hard-packed streambed is being mined, the cobbles and boulders (i.e., rocks that are too large to pass through the recovery system) are tossed back onto a pile behind the production area. As the production area moves forward, piles of boulders and cobbles are left behind in place of the original hard-packed streambed. Sometimes, sand, silt and gravel that is processed through the recovery system is dropped on top of the cobbles. Later, winter storms also wash sand, silt and gravel across the top of the cobbles. The sand, silt and light gravel then filters down and fills in most of the space between the cobbles. Therefore, tailings usually end up as loose stacks of cobbles with sand, silt or light gravel filling the spaces.

A large flood-storm may wash the tailing-cobbles away at a later time and redeposit them into a newly-formed hard-packed streambed. Or, as in the case of the 1964 flood in northern California, rather than wash away all of the cobbles, many of the piles were leveled off by the storm, and a new layer of hard-packed streambed was deposited directly on top of the loose cobbles. When we dredge sample holes in those locations, we usually find a hard-packed streambed on top of the tailings (loose cobbles). If gold traveled in that part of the waterway, we find it concentrated at the bottom of the hard-pack, sitting on top of the tailings. Underneath, we find loose cobbles with sand and silt between them. These usually go all the way to bedrock. We find very little gold on bedrock, because it has not yet been directly exposed to a major flood storm since being mined.

  

Some waterways will have several different natural streambed layers, each with its own concentration of gold resting on top of the layer or bedrock below. Different streambed layers usually exhibit a different color and compactness. The “contact-zone” between the layers is generally pretty easy to spot. Within the contact zones between layers, and on top of bedrock, is where you will find most of the gold concentrations. Those areas, then, should be the target of your sample holes.

As shown in this following video segment, sometimes the highest-grade deposits will be found up on top of a layer of hard-pack in the streambed:

Seldom will you find rich pay-streak gold deposits associated with loose streambed material. However, it does occasionally happen. These occurrences are almost always the result of winter storms, and the resulting run-off, eroding away a hard-packed streambed along the bank — which washes the gold down into the waterway to rest with the loose material.

There are areas in Africa where streambeds consist entirely of loose gravels – sometimes which carry substantial amounts of gold and/or gemstones. But this is an exception to the rule.

Effective sampling is the key to a successful mining operation. And, when you are sampling, you should be looking for hard-packed streambed layers. Watch for the gold concentrations along the bottom of these layers, because that is where you will usually find them.

In the summer of 1850 the “Klamath River Indian Tribes” witnessed first-hand the ferocity of early American “Gold Fever.” White men soon came into the mountain forests of this winding river. At least three groups of prospectors ventured through Yurok and Hupa Indian lands into the territory of the Karuk people. Stories of hundreds of gold diggers coming into other valleys of California had come to the Klamath River Indians from Indian tribes like the Pomo, Wintun, and the Wiyot. Gold hungry men were coming into their territories. “White men like the rivers! White men dig up rocks,” said these peaceful Indians, bewildered by such behavior.

One group of early miners, approximately eighteen men, traveled the millennia-old foot-trails of the Karuk people, up to a place of broad gravel bars and exposed bedrock two miles upstream from Clear Creek. For thousands of years the Karuk Indians lived along the river on similar “flat” campgrounds, ancient gold-bearing deposits of river gravel!

The Karuk were a peaceful people. They believed that a great and peaceful race of white people lived here before the Karuk Tribe came to the Klamath River. They were uncertain of what they should do with regard to these white men. Were they the peaceful white people returning? Unfortunately, they would soon learn otherwise.

Some white prospectors took advantage of the Karuks. They used them for trail guides and as teachers of survival skills. Prospectors had a rough time living on only the meat that they hunted or the food they’d packed with them. The Karuk Indians utilized salmon, deer, and elk as their primary meat sources. They also gathered and used more than two hundred species of plants. Nutritious acorns of the tan oak and other oak species formed a large part of their diet. The Karuks used nearly as many plants and herbs for medicinal and spiritual purposes.

At times of peace and acquaintance, the two cultures learned many new things from each other. During times of conflict, powerful guns of the white men won most battles. Arrows and flint-knives had little chance against the power of guns. Revolvers like the .44 caliber Walker Colt and the .36 caliber Texas Colt gave the miners firepower. “Long-rifles,” like the .50 caliber Hawken, gave the owner the capability of killing a human, or a deer, at a range of 200 yards. The original 49’ers carried rifles, 5 and 6 shot revolvers, Derringers, pepperboxes, knives; or some such assortment. Outlaw miners in boomtowns were actually more of a danger than the so-called “wretched” Indians.

Good amounts of gold were first found at a campsite now known as Wingate bar. Digging produced much gold! Trouble came quickly. Two miners were killed by the Karuks at Wingate Bar, just north of the large Karuk village of Inaam, (Clear Creek). To avenge the killings, the white men formed a battle group. In a raid at first morning light, they killed all the Karuks present. Only a few got away. All the Karuk wood-plank homes were burned. Sporadic fighting went on for perhaps several weeks, with repeated attacks on the white men. These attacks finally caused the prospectors to pack their animals and head back down-river. They forded the river and climbed out of the river canyon, crossed the rugged terrain of the south Marble Mountains. It is believed that they took this route to avoid the large Karuk villages at the mouths of Ti Creek, Salmon River, and Camp Creek. There were seven villages at the mouth of the Salmon River. It was the “Center of the World” for the Karuk Tribe. They ended up in the Salmon River canyon, making winters’ camp at Brazill Flat (named after the great-great grandparents of the author.) This was at Forks of Salmon; land of the Konimihu Shasta Indians.

The second party of prospectors braving the wild country and tough Indians kept to the west and north sides of the Klamath River. Their travels took them along steep ridges and into scores of forested tributary watersheds of the Klamath River. (It must be understood that the forest was much more open then than now. White people began the suppressing of wildfires in the early decades of this century. The Karuk people allowed forest fires to burn, even setting fire to areas that were getting too brushy. This burning allowed new sprouts of grasses and shrubs to grow, made travel better, made hunting easier, and made spotting an enemy before he got too close more probable.)

This second party was headed for the Scott River. However, they must have traveled either through Seiad Low Gap into Horse Creek, or went up Johnny O’Neil Ridge and down Hamburg Gulch. They missed the mouth of the Scott River. They traveled up the Klamath River as far as the mouth of the Shasta River, in Shasta Indian territory. It’s believed that they wintered in the area soon to be called Thompson’s Dry Diggin’s; now known as Yreka. Gold was found there, but the land was dry; a high desert land. Gold was found in the ancient mixed soils of the valley bottom, including the roots of the bunch grass.

The third party searching for gold in these mountains in 1850 included the man now known to have made the biggest gold discovery in the Klamath Mountain Province, John Scott. It is still uncertain exactly what route they took before finally ending up at Scott’s discovery site of nuggets at Scott Bar. (The largest nugget found in later years, found by Wade & Lindsey, was “five inches long, three inches wide, and weighed 16 pounds!) It has been reported that this band of miners came inland from the port town of Trinidad in California. In the next several years, we know that supplies were brought to Scott’s Bar by way of Trinidad, Blackburn’s Ferry (Cappell Creek,) and the wind-swept summits of the Marble Mountains. Later supplies were brought by pack trail (named the Kelsey Trail after one of the mule packers) from Crescent City over the mountains of the South Fork of the Smith River, Bear Peak, and the northern Marble Mountains.

In 1851, the prospectors who had wintered near the Forks of Salmon, at Brazill Flat, lived through the winter pretty well. However, in the early months of spring they were surprised to see other eager and gold-hungry miners scurry into the Salmon River country. The new group crossed the Salmon Mountains before winter was really over. Spring snowstorms made life miserable for these hasty prospectors! As they waited for warm weather, they ended up eating all the stores of the miners already there. This was called “Starvation Times” in the Salmon River!

By July of 1851, the group of prospectors that retreated from Wingate Bar, led by Captains McDermitt and Thompkins, (owners of Blackburn’s Ferry), moved from the Salmon River back up the Klamath River. They found very large amounts of gold in the gravel at the mouth of Indian Creek. They’d survived the mountainous trails, the river fording, battles with the Karuk Indians, and “Starvation Times.” Now they had good food, warm weather, and lots of gold nuggets! This gold-rich location, and easy living circumstance, was named a “Happy Camp!
