History & Geology
The Long Road to Gold Point, Nevada
September 2013 by Bill Rich
Apart from the hard rock mines, there are abundant gold-bearing placers, especially in the areas in and around Oriental Wash.
Copper Deposits of Alaska
Only the famous Kennecott copper mine was able to continue operating through the Depression owing to the exceptional richness of its ore.
Enrichment of Mineral Deposits by Weathering—Part I
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.Potholes and Other Bedrock Traps
Potholes in bedrock can trap placer minerals and even be glory holes. They are, at least, interesting geologic phenomena, and at best, a treasure trove of gold nuggets.
Epithermal Gold and Silver Deposits
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.
Prospecting for Diamonds in Kimberlite
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
Prospecting Homonyms
Three homonyms come to mind when I think of gemstones, gold and vegetables: carrot, carat and karat. Let’s look at carrot first.
The Preacher of Sheeps**t Flats
It seemed that the preacher always gave the same answer to anyone who asked where his gold had come from. His answer was, “If you know your gold, you can find it. However, you will have to find it the hard way, the way I found it.”
