For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Many locals are just waiting for California to allow dredging once more, especially with the current gold prices. There are still plenty of good opportunities for prospectors in this area, just as it has been for so many years.
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.
