Geologic setting

Geologic description

Small-scale placer mining in 1902 and 1903 recovered about 60 ounces of gold from a bench along Grace Gulch (Collier and others, 1908). This bench is a possible continuation of the one mined on the south side of lower Buster Creek (NM304). A northeast-trending high-angle fault juxtaposes marble and schist units near this site (Hummel, 1962 [MF 247]).
