Gold Deposition and Gradients of Placer Streams—Part I
June 2012 by Jim HalloranWhen placer miners from the gold rush era began experimenting with the slope of their sluices, they must have pondered the ideal slope for trapping gold in a creek bed too. Logic suggests the same is true for streams...
The process of recognizing ores all starts with being able to recognize some basic minerals and knowing what hard rock ore looks like in the districts where you prospect.
My partner had the contacts and it wasn’t long before we had an agreement in place and the company had a geologist on site. I recall a time when he was getting the lay of the land, so to speak, and he broke off a rock sample and inspected it with his magnifier.
The Beatty Mining District in south-central Nevada has been one of the most productive Mining Districts in the state, producing millions of ounces of gold together with silver, fluorite, mercury and other valuable minerals.
Mining “giant” John A. Miscovich died August 22, 2014, at the age of 96. He was the well-known inventor of the “Intelligiant” water cannon.
While 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.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
It is a gemstone, and yet it is also closely associated with many types of metal ores. It's valuable itself but often points toward other valuable minerals—that is certainly something prospectors want to know more about!
