Alteration: Strong argillic alteration; silicification; large argillized area 1.25 miles square
Commodity: Ore Materials: gray sulfide minerals Gangue Materials: Clays, quartz; iron oxides after pyrite
Deposit: The deposit consists of a stockwork vein system in latite host in a pediment area exposed by recent erosion. Host rock has been affected by strong argillic alteration with some clays and iron-stained quartz. Minor wispy gray streaks of sulfides occur in quartz veining. Some siliceous sinter is associated with a rhyolite plug along the west edge of the altered area.
Deposit type: Epithermal vein, Comstock
