Enrichment of Mineral Deposits by Weathering—Part II
April 2016 by Chris RalphWhile both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.
Many locals are just waiting for California to allow dredging once more, especially with the current gold prices. There are still plenty of good opportunities for prospectors in this area, just as it has been for so many years.
Even though these were some of the earliest placer deposits to be worked, there is still plenty of gold left today—it just takes more work to recover. Knowing about the old locations where gold has been found is the first step to success.
Sylvester Smith and his younger brother Nathan were among this group who rode and led their Indian ponies, while climbing the rugged Salmon River breaks and rockhewn mountains, looking for a path that would lead them up and over the uncharted wilderness.
This mine was a real wonder of engineering, and the water supply and drifts had to be carefully managed to keep it in operation. In fact, it didn’t close due to lack of gold, but instead closed with the fall of the Roman Empire.
What many people don’t realize is that the Comstock Lode produced over 8,000,000 ounces of gold…
There are a load of ways to do research, and I’m going to talk about how I do it—maybe you’ll get some ideas that will work for you, too.
In 1967, a local resident showed me a pouch of small gold nuggets and flakes. Several years later I asked the same person where that gold was found. He responded, “From the streambed below the old stamp mill at Apex.”
