Location and accuracy This prospect is at an elevation of about 3,150 feet on the west flank of Wells Mountain, approximately 2.8 miles west-southwest of VABM Wells and 1.1 mile north-northwest of hill 4035. The prospect is in the NW1/4SW1/4 sec. 20, T. 27 N., R. 1 E., Seward Meridian. The location is accurate to within 1/4 mile. This is locality 86 of Csejtey and Miller (1978).

Geologic setting

Geologic description

This prospect is in altered granodiorite that contains disseminated pyrite (Csejtey and Miller, 1978). Samples collected by the U.S. Geological Survey contain up to 70 parts per million molybdenum and 100 parts per million copper (Miller and others, 1978). Cities Service Minerals Co collected 75 soil samples and 25 rock samples here (Don Stevens, written communication, 1992).
