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.
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.
Three homonyms come to mind when I think of gemstones, gold and vegetables: carrot, carat and karat. Let’s look at carrot first.
