Researching Mineralized Areas
December 2015 by Chris RalphThere 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.
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
Silver Peak is a small mining community in Esmeralda County in west-central Nevada, about 30 miles west of Goldfield. Although it’s fairly remote, it’s been an important mining center since the early days.
How rich does a hard rock ore have to be for it to be worthwhile to process and extract the gold?
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
Only the richest ores could be worked and shipped off for processing at a profit. As a result, early mining in the southern part of the Humboldt Range was short-lived. In the 1880s, placers were discovered in Spring Valley and American Valley on the east side of the range...
The excitement over IOCG deposits began with the discovery of a monster deposit at Olympic Dam in Australia in 1976. The discovery was accidental as the operator was searching for strata-bound copper deposits.
We descended hunched over, down a long, steep, wooden staircase to the 1,000-level.
