An Au,Ag,Cu,Ni,Pt,Pb mine

This mine is located 4 miles north-northwest of Harts Pass.

It worked a fracture zone in limey and graphitic argillite that contains interlacing quartz veinlets, graphitic shear zones, and breccia zones cemented by quartz and sulfides.

Developments include several tousand feet of workings on six levels as of 1956.

It produced 60,000 tons of ore in the early 1900s, several tons of high grade ore from 1940-1942, 24 tons of concentrates in 1947, 300 tons of ore in 1949, 300 tons in 1963, and 7 tons of ore in 1978.

The total production is estimated to be about $1,250,000.
