Description

Excerpt from Ore Deposits of the Silver Peak Quadrangle, Nevada

A special type Of auriferous deposits in the Mineral Ridge district is represented by the Great Gulch mine. This is a deposit of auriferous arsenopyrite, which is believed to be similar in age and origin to the subsequent ores of the previously described gold mines.

On the margins of the auriferous quartz district Of Mineral Ridge are a number of mines and prospects containing more silver than gold. The general geology is like that Of the gold-bearing ores. Alaskite and quartz lenses are intrusive into metamorphosed sediments and are accompanied by greenstone dikes. The ore, how ever, is subsequent and has formed along cracks in the primary quartz. The whole history indicated is analogous to those auriferous quartz mines of the Mineral Ridge district which show notable subsequent mineralization, although the char acter of the ore in the silver mines is somewhat different, in that more silver and copper in proportion to the gold are present. Another type of silver-bearing veins has a gangue of contemporaneous quartz, and has formed by replacement of dolomite near the edge of the auriferous quartz district.
