Location and accuracy This lode prospect is at an elevation of about 300 feet on the north side of Dexter Creek (NM303) about 300 feet upstream of the mouth of Grouse Gulch and about 5,700 feet south of the summit of King Mountain. It is at the east-central edge of section 31, T. 10 S., R. 33 W., Kateel River Meridian. It is locality 49 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The location is uncertain, but it probably is within 1,000 feet.

Geologic setting

Geologic description

A 400-foot tunnel driven in or before 1907 was reported by Smith (1908, p. 240). The ore reportedly contained about 4 percent copper. Moffit (1913, p. 135) proposed that gold in the deposit was more valuable than the copper. Country rock is probably the marble-rich unit mapped by Hummel (1962 [MF 247]).
