41405

Long-form identifier:

mindat:1:2:41405:7

GUID (UUID V4):

Deposit: Fissure veins in zone of silicified devitrified rhyolite. Zone is cut by 3 of 4 parallel veinlets carrying quartz, argentite & free gold. Located near frazier creek, the only developement is a 100 ft. Tunnel driven northward along strike of a silicified Fe-stained zone of rhyolite ; info.src : 1 pub lit

Deposit type: Epithermal vein, Comstock

Geology: The mine is in an area of white devitrified rhyolite whidh is similar to that east in gold circle district proper. A zone of silicified rhyolite is cut by three or four parallel veinlets up to 10in wide which carry ribbons of quartz, argentite, and free gold.
