Geologic setting

Geologic description

This occurrence consists of locally mineralized quartz veins in dolomite (Chipp, 1972). A selected sample of quartz with unspecified sulfides and malachite contains 2,100 ppm copper and 2.4 ppm, silver. A second sample of vein quartz, taken approximately 0.2 miles to the north, contains malachite but no elevated metal values. The rocks in the vicinity are Devonian schist and phyllite (Chipp, 1972). No other information is available.
