Location and accuracy The map site of this occurrence is at an elevation of 500 feet, 0.9 mile due south of the top Red Bluff Mountain (MacKevett and Holloway, 1977, locality 7; Wilson and others, 1988, locality 7). The location is accurate to within 1 mile.

Geologic setting

Geologic description

The rocks at this location consist of sedimentary units of the Paleocene to Eocene Tolstoy Formation (Wilson and others, 1995). The occurrence is described by MacKevett and Holloway (1977) as an altered zone associated with Tertiary granitic rocks. U.S. Geological Survey mapping in the mid-1980s shows no granitic plutons in the area (Wilson and others, 1988). Samples of sedimentary rock collected in this area by the U.S. Geological Survey in the mid-1980s contained as much as 100 ppm copper, 20 ppm lead, and 150 ppm zinc (Angeloni and others, 1985).

Production and reserves

Workings or exploration The U.S. Geological Survey mapped and sampled this area in the mid-1980s (Wilson and others, 1988). Samples of sedimentary rock contained as much as 100 ppm copper, 20 ppm lead, and 150 ppm zinc (Angeloni and others, 1985).
