A former Au-Ag-Zn-Cu-Fe-As-Pb mine located in sec. 29, T8S, R31E, MDM, 1.5 km (0.9 mile) SSW of Aspendell, along the Middle Fork Bishop Creek (1 mile N of Lake Sabrina). The property consisted of 34 claims, 14 of which are patented (Rocky Point group). MRDS database stated accuracy for this location is 10 meters.

Mineralization is hosted in quartzite. The ore body strikes N55W and dips 70NE at a thickness of 4.88 meters. Ore controls included a fracture zone. An intrusive monzonite-granite, 800 feet wide, cuts quartzite. The contact strikes N50W and dips 60SW. The veins average 8 feet thick. There are 4 ore shoots, 20 to 300 feet long, 6 to 16 feet thick. Ore contains free gold and sulfides. Associated rocks include monzonite. Local rocks include Paleozoic marine rocks, undivided, unit 3 (Eastern Sierra Nevada).

Local structures include the Haggerty Fault which strikes N60E and dips 45 SE, displacing the ore bodies 130 feet to the NW. It also displaces granitic sills that cut the ore bodies.

Workings include underground openings with an overall depth of 274.32 meters, and comprised of a 600 foot deep shaft. The first 100 feet are vertical and the remaining 500 feet are inclined 68NW. There are levels at 60, 200, 300, 400, 500 & 600 feet. There are 1,400 feet of drifts on the 200 foot level, driven to the NW. In all, there are about 4 miles (about 6.6 km) of drifts and raises.

Production data are found in: Tucker and Sampson (1938), and in Goodwin (1957).

Production information: Approximately 99% of the ore was Au with a little Cu & Ag. The ratio of concentration in the mill was 30:1, with a recovery of 92%. No other production record was found.

Analytical data results: Ore assayed $10 to $12/ton (period values).
