The Goldfield Mining District, Nevada—Part II
July 2017 by Chris Ralph
The majority of the gold produced in Goldfield has come from ores that are close enough to the surface to be oxidized by the air. This oxidized ore is normally a soft, shattered, earthy material usually stained yellow to brown by oxides of iron.
These were the men who periodically picked up the gold amalgam from the tables and sluices in the dredge, processed it, and transported the gold ingots to the railroad express office in Alder. Their trustworthiness must have commanded a prominent wage.
When my field assistant Jay Roberts and I entered the mine, it appeared as if someone just walked out of the mine, turned off the lights and never returned.
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.
Prospecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.

• By the numbers...
I’ve been taking a look at the mining and uses of a number of critical metals in series of articles, and it’s time to take a look at antimony.
Apart from the hard rock mines, there are abundant gold-bearing placers, especially in the areas in and around Oriental Wash.
