Location and accuracy This occurrence is on an east-west-trending ridge that separates two headwater forks of Ganes Creek in the Beaver Mountains. This occurrence is at an elevation of about 2,600 feet, about 0.7 mile northeast of peak 3490, and about 0.6 mile northwest of the center of section 25, T. 32 N., R. 41 W, of the Seward Meridian. The location is accurate.

Geologic setting

Geologic description

This occurrence is a mineralized, iron-stained, fracture zone in monzonite (Miller, Bundtzen, and Gray, 2005). One grab sample collected by the U.S. Geological Survey in 1986 contained 1.0 part per million (ppm) silver, more than 2,000 ppm boron, 300 ppm copper, 100 ppm lead, and 0.32 ppm mercury (McGimsey and others, 1988). Two grab samples collected by Battle Mountain Mining Company contained up to 941 parts per billion (ppb) gold, 88.5 ppm silver, 1,180 ppm copper, 3.16 percent lead, 1,784 ppm zinc, more than 2,000 ppm arsenic, 904 ppm antimony, more than 50 ppm mercury, and 68 ppm tin (Szumigala, 1993).
