Location: This placer mine is at an elevation of approximately 1,800 feet in a small basin, 1.2 mile west-northwest of Sheep Mountain, 3/4 mile north of Roberts Peak, and 1.5 miles west of Clark Peak. It is in the NE1/4SW1/4 section 20, T. 41 S., R. 68 E. of the Copper River Meridian. The location is accurate.
Geology: The Lurvey placer was discovered in 1881 in a small basin near the Perseverance Mine (JU168). It was developed by a 343-foot drainage tunnel and a 90-foot raise (Spencer, 1906).

The basin is approximately 700 feet long, 300 feet wide, and up to 20 feet deep. Approximately 40,000 cubic yards were mined but there are no production records available (Redman and others, 1989).
