We have learned over the years that no matter how good some mining property is, most beginners and moderately-experienced prospectors might need a little help in figuring out how to locate high-grade gold deposits. This is partly because different geographical areas may have been affected by different types and magnitudes of geological events which may have deposited gold in different ways. While the fundamentals will be the same everywhere, finding high-grade gold deposits in our part of the world may require a different prospecting focus than elsewhere.

Some people arrive in Happy Camp who have never even prospected for gold before. Some have never seen gold in its raw state. Some who arrive do not even believe there is any gold left to be found! Just about everyone arrives needing some amount of assistance in understanding how successful gold prospecting is being accomplished along our mining properties.

This is why we started organizing weekend group mining projects, and have been scheduling them throughout each mining season for the past 20 years. We know how important it is for members to get off to the right start on our mining properties. So I personally join in and supervise nearly all of these weekend projects, myself. I also get a lot of help from other experienced members who enjoy going out on a weekend and finding gold; sometimes, lots of it.

We had a number of experienced helpers along on this particular weekend project. Otto Gaither is often referred to as “The High-banker Kid.” That’s because his personal high-banking machine is always producing in good gold. Otto has been helping out on all of the weekend projects for several years. Craig Colt has also been helping for years. Craig’s nick name on the river is “The Nose.” This is because Craig can smell-out a high-grade pay-streak better than anyone else that I know. While we went into one of Otto’s favorite high-banking areas on this project, it was Craig that found the rich gold deposit. Together, we make a great management team for these weekend gold mining projects!

 

The way that Craig finds these gold deposits, is that he just aggressively follows our basic sampling plan. It is the very same plan that we use in all of our gold mining projects. This is a simple plan that we have developed over many, many years of serious prospecting. Because it is the plan that will get you into high-grade gold every time, we devote a big part of these weekend projects explaining and demonstrating for everyone how it is done. In fact, this is the reason we organize these projects in the first place; to get as many members as possible following a sampling plan that works!

Our weekend high-banking projects are free. But you must be either a Full, Associate or Affiliate Member to participate. Each participant receives an equal share of all the gold that we recover on Sunday.

Weekend projects begin at 9 am on Saturday morning. Participants arrive at our headquarters (from all over the world), and are directed down to the Happy Camp Lions Hall where there is a comfortable place to sit down. A fresh pot of hot coffee is always ready to go. After introductions, we devote the remainder of Saturday morning to a discussion about where we will be going, and about how we will all be working together to locate a high-grade gold deposit. Using a chalkboard to demonstrate the theory, I invest a few hours into providing a substantial explanation of what the basic sampling plan is, and why this plan will always lead you into high-grade (as long as high-grade exists within the area that you are prospecting). I make it a point to answer any and all questions.

After lunch, we meet back at headquarters and carpool to whatever mining property we have chosen for the project. Sometimes we use a boat to get everyone across the river.


This particular project found us prospecting on the Highway 96-side of upper K-15A, otherwise known as the “Upper Mega-Hole.” Participants are supposed to bring their own basic prospecting tools, and especially a gold pan. They should wear clothes and foot ware that they don’t mind getting dirty and wet. A container or two of drinking water is always a good idea!

After everyone is gathered together out on the mining property, I take a moment to relay all or most of

the important information that we have collected from previous mining activity in the area. This is veryimportant; because knowing where others have found high-grade in the past will allow everyone a head start in being able to find more during the project.

Because gold is very heavy, it follows a common path down the waterway, and nearly always deposits along the bottom-edge of hard-packed layers of streambed. So if you know where others have already found high-grade in the area, you then know where to target your samples to find it again. This is what the basic sampling plan is all about! Since we do not have much time on a 2-day project, my personal mission is to direct as much energy as possible towards the areas where the gold is most likely to be found. The following video sequence captured some of our beginning moments as we began sampling for high-grade:

Once we are out there, the first thing everyone needs to do is demonstrate that they can operate a gold pan well. The remainder of Saturday will be devoted to locating a rich gold deposit with the use of gold pans. If your panning method is not capturing every speck of gold, you can easily miss the pay-streak even if you place your samples right down in the middle of a good deposit!

So after providing a panning demonstration to everyone who wanted to see it, I devoted the first hour or so just going around and critiquing everyone’s panning methods. Otto also helps with this. It usually comes down to just a few people who need some extra help. We focus on that until everyone in the program knows how to pan for gold without losing any in the process.

Since it is also important that we find high-grade before Saturday is finished out on the river, Craig and other experienced helpers usually get started in a serious sampling effort as soon as we get out on the river. This day was no different. Craig disappeared soon after we arrived on the river. So, as soon as everyone was panning alright, I went hunting for Craig to see if he had made any important gold strikes, yet. I found him towards the upper-end of K-15A. Craig was digging around the top layer of big rocks within the top layer of hard-pack.

Hard-packed streambed viewed from the surface.
Fortunately, most of the high-grade gold deposits that we find in surface mining (out of the water) are located around the top layer of imbedded rocks. I say “fortunately” because it means you usually do not need to dig very deep to recover the gold. We believe most of the gold that we find in this top layer of hard-pack is gold that has washed down during large winter storms. This is why some prospectors call it “flood gold.” Imbedded rocks which protrude up through the surface layer form natural riffles. Gold being washed downstream during high-water becomes trapped between the rocks. Sampling is mainly a matter of freeing-up the top layer of embedded rocks, and panning the gravel-material that is between and just under them.

Craig was busy following the basic sample plan when I found him. He had placed himself in the same path, just a short distance upstream from where some earlier prospector had made a strike. Craig was gathering his sample along the bottom of the same layer of streambed that the other prospector was finding his gold. As Craig was digging in hard-pack, he already knew that no other prospector had been there since the flood layer was created by a major flood storm (probably the great flood of 1964)

In gold prospecting, the bigger the sample, the more accurate and dependable the result is going to be. Since we cannot make our gold pans bigger, we compensate by using a classification screen to eliminate larger-sized gravel and rocks. This allows us to double or triple the amount of gold-bearing-sized material that we actually process in the pan. Craig was screening his sample into his gold pan through an 8-mesh screen. The larger-sized material was being tossed to the side of where he was digging.

I showed up just in time to watch Craig work his sample down in the gold pan. And sure enough, there was a good showing of gold in the pan; 3 or 4 nice middle-sized flakes. Craig told me that the previous several pans were about the same. So Craig had already made a strike for this weekend project, just in case we were not able to find something better during the next few hours. This was good; my worries were pretty-much over for this project! Craig is my personal insurance plan that we will always recover some amount of gold on these projects!

Having been managing these prospecting events for more than 20 years, my worries come down to: (1) don’t hurt anyone, and (2) make sure everyone leaves knowing how to operate a gold pan, and (3) send everyone home with as much gold as possible!

Wandering back down to where most of the others were actively sampling, several participants already had some pretty encouraging results of their own to show me. This is always the most rewarding part of the weekend for me. My job out there is to look at and compare the results of all the sampling. Someone is always finding something that looks encouraging. So, I ask others who have not been finding very much to help expand the sampling effort where we are finding more gold. Within an hour or so, we usually have everyone out there doing pan-samples in several different strikes. There can be a lot of excitement to go along with this. This is especially true with people who have never found their own gold before!

Here is a video sequence that captured how we were all working together to establish some high-grade gold:

One of the most valuable things we do during these weekend projects is show all of the participants exactly what hard-packed streamed is. “Hard-pack” is streambed that is formed by a major flood storm after pay-streaks are already formed. There is a world of difference between loose material or tailings from earlier mining activity, and naturally-formed streambed material (hard-pack). It is vital to know the difference, because almost all of the high-grade gold you will find along New 49’er mining properties will be located at the bottom-edge of one or more layers of hard-packed streambed. Knowing what to look for allows you to target your sampling activity at the right areas.

Another very important thing we do in these weekend projects is demonstrate how to place a relative value upon the amount of gold that is being found in a pan-sample. It is not unusual for a person to walk up with a great sample result, and say, “I didn’t get very much!” And it’s true that there is not very much gold in the pan. But that small amount of gold is only from about a single shovel of streambed material. That is a very small volume! Getting 4 or 5 nice little flakes of gold in a single pan can relate to a half-ounce or more of gold on Sunday when we have a dozen people shoveling the very same material into a high-banker!

 

A small showing of gold in a single pan-sample can add up to a lot of gold once you start processing more volume!

So, one of our goals during these projects is to help all of the participants gain the ability to relate how the gold found in pan-samples (on Saturday) will add up in a high-banker that will process more volume of the same material (on Sunday). While I am evaluating pan-sample results on Saturday afternoon, I make it a point to show around the sample results coming from the areas that we will work as a team on Sunday. I also try and get everyone to do some personal panning in those very same areas. This goes a long way to help beginners form a personal judgment about what is a good sample result when panning.

But on this particular day, most of the participants were totally absorbed in all the gold they were finding. Everyone gets to keep for themselves all the gold they find on Saturday afternoon. There was a lot of excitement going on; some people were yelling out their enthusiasm, having found their first-ever gold!

We do a weekly potluck gathering at the Happy Camp Lions hall nearly every Saturday evening during the season. The gathering starts at 6:30 pm, and we start dinner at around 7 pm. Then we do a short meeting and have a prize drawing. We have a lot of fun, and it gives members a chance for a weekly get-together.

Some members look to the Saturday evening potluck as the highlight of their week!

To give everyone some time to clean up and pull something together to contribute to the evening meal, we wrapped up the sampling program out on the river at around 4:30 pm. Some participants were having too much fun out there to quit when we did. Still, I did notice that they made it to the potluck in time for dinner! We filled the Lions hall that evening, as we usually do.

Sunday morning found our energetic group packing several motorized high-bankers over to where we had made our strikes the day before. A high-banker is basically a sluicing device which can be set up near to where you want to dig. This way, your pay-dirt can either be shoveled or dredged directly into the recovery system, rather than packed some distance across land. A motorized pump provides water to the system through a flexible pressure hose.

With all that help, it did not take us very long to get things set up. We split the group into three different teams, each to operate their own high-banker. It wasn’t long before team leaders on each crew organized the activity. Some people were tossing the top loose rocks into piles. Others were using picks and pry bars to loosen-up the top layer of hard-pack. Others were filling 5-gallon buckets about half-full and packing the pay-dirt just a short distance to the high-bankers. Others were pouring a steady feed of material into the high-bankers. There was a whole lot of productive activity going on! Check out the following video sequence:


Once I was sure the high-bankers were operating with the proper water flow, and that they were being fed with pay-dirt at a good speed (not too fast, not too slow), my focus turned to the tailings water coming off the high-bankers. Dirty water is not allowed to flow back into the river. This is something that always determines where we set up the high-bankers in the first place! In this case, we had found a location where natural contours up on the gravel bar had already created a place that would trap the dirty water. That water was seeping into the gravel bar about as fast as we were pumping it up there. So we were not going to have any worries about washing dirty water back into the river.

The other main job I have is to keep an eye on what participants are shoveling into the 5-gallon buckets that will be fed into the high-bankers. We only want high-grade material in those buckets! Once in a while, we get someone trying to help things along by shoveling sand or low-grade material into the buckets. That is counter-productive, because those low-grade buckets will ultimately be processed instead of other buckets that would contain high-grade material (more gold). Why do people do this? It’s usually because the loose material is easier to dig, and everyone wants to feel like they are helping.


You learn early in gold mining that you can work all day and not recover very much gold if you are shoveling the wrong kind of material! But this particular group had been listening when I talked to them about this, and they were focused upon filling buckets with material from the layer of streambed that we had identified as being the pay-dirt.

After a few hours of good hard work, we shut everything down for lunch and took a look in our recovery systems. There was lots of gold to be seen there. Some people were hooping and hollering, which is music to my ears. Enthusiasm is a good thing!


We don’t normally clean-up the recovery systems at lunch. This is because the process generally is time-consuming and would likely subtract from the amount of digging we can accomplish after lunch. After seeing all that gold, everyone ate just a little faster than normal so they could get back to work! This is pretty normal. Several participants were already filling buckets even before I finished my peanut butter and jelly sandwich. Gold fever! Everyone was pretty excited!

 

We processed more pay-dirt for another hour and a half after lunch. I closely watched how things were going. It gets pretty hot out there on Sunday afternoon. When people start slowing down, I know its time to begin shutting things down for the day.
Of course, the first part of shutting things down involves removing all of the gold concentrates from each recovery system. This was the part everybody had worked so hard for all day! The following video sequence captured some of those magic moments as we all got our first good look at the gold that we had recovered:

While one part of the crew cleaned the concentrates from the recovery systems, everyone else pitched in by back-filling our excavations with the rocks that we had been carefully placing in piles all day. By the time we left the area, you could not tell we had ever even been digging or prospecting there. This is the right way to leave a prospecting excavation when you are finished with it!

This is what an area should look like after you have finished prospecting there!

Note: I returned there a few weeks later with the top minerals officer for the Klamath National Forest, and he was not able to point out any of the places where we had been mining!

We timed things so that we were back at headquarters in Happy Camp with our final concentrates at around 2:30 on Sunday afternoon. What do I mean by “concentrates?” Like most other gold recovery systems, high-bankers do not just recover the gold. They recover a concentrate of all the heavy materials which have been shoveled into them. Concentrates normally consist of some (iron) black sands, along with the gold that has been recovered.


Back at our headquarters in Happy Camp, our mission for Sunday afternoon was to separate all of our gold from the other concentrated material. We have a special garage area in the back of our building where this final clean-up process is accomplished. As this is something that every prospector needs to know how to do, we always invite all of the participants to either watch or help with the process. This enthusiastic group was all too ready to help!

We use a special device for final gold separation which is called the “Gold Extractor.” This is basically a finely-tuned, narrow sluice that uses very low-profile riffles. In 30 years as a serious prospector, I have never seen a more effective portable tool for reducing concentrates down to a very small volume (about the amount of a rounded tablespoon) – with zero loss of gold during the process. The whole idea is to reduce the amount of concentrates down to a small enough volume that can be dried for final separation.

Our most experienced panners went through the tailings from the Gold Extractor and were not able to locate a single speck of lost gold. Everyone was happy about that!

After drying our final concentrates, we passed them over a set of final clean-up classification screens to separate the material into several different sizes. The different sizes of concentrate were then placed on separate clean sheets of paper so we could carefully complete the final separation – mainly by gently blowing away the iron sands. This is usually not very hard to do, because the iron is about 3 times lighter than the gold.


By around 5 pm, we had all the gold cleaned up and on the weight scale. It weighted out at about 13.3 pennyweights. That’s almost 3/4 of an ounce. This was pretty good for about 3 ½ hours of hard work! It was especially good, being that none of us even knew that particular gold deposit existed on Saturday morning!


After taking a few moments to pat ourselves on the backs for a job well done, I carefully weighed the gold into equal shares for everyone who participated. I like to place the gold shares in small glass sample viles. But some people prefer to keep their shares in small zip lock baggies. Here is a video sequence that captured part of the final clean-up:



The project was over by 6 pm on Sunday evening. Some participants went away with the first gold they had ever found. Most went away with big smiles on their faces. Everyone went away with a full understanding of how successful gold prospecting is accomplished, from pan-sampling, to production-mining on a small scale, to final clean-up and gold separation. That was going help each of them to become more successful in their own prospecting activities.
