Report: This mine has been divided into two main areas of workings although the occurrence and minor workings stretch along the entire ridge, from 6800 feet elevation to 8000 feet elevation. Pattee (1960) shows maps of most of the workings in detail. According to Pattee, the area has been explored since 1907 with a concentrated effort in the 1950's when 21,150 tons of 0.18% WO3 was mined. Ore minerals include scheelite, with powellite and malachite occurring in metamorphosed Amsden intruded by Mount Torrey quartz monzonite. Again according to Pattee, workings near the "H" adit include open pits, trenches and one open main adit. Faulting and barren lenses of country rock break up the continuity of the deposit. The adit has a gate on it but the locks have been broken off the hasps. Until the gate is secured with new locks, it should be considered hazardous.
