Are modern geothermal waters in northwest Nevada forming epithermal gold deposits?

Hydrothermal systems currently are active near some gold deposits in northwestern
Nevada. Possible links of these modern systems to goldmineralization were evaluated
by chemically and isotopically analyzing water samples from the Brady, Dixie
Valley, Humboldt House, San Emidio-Empire, Soda Lake, andWabuska geothermal
areas. In addition, quartz veins from Humboldt House and the adjacent Florida Canyon
Mine were analyzed to compare ore and gangue phases with those predicted to
form from proximal hydrothermal fluids.
