A former Au-PGE (Pt)-Co-Ni-Sn mine located in secs. 1 & 12, T4S, R19E, MDM, 2.6 km (8,600 feet) W of Peachtree Bar, along Devil Gulch near its confluence with the South Fork Merced River (5 miles S of El Portal), on National Forest land. Owned by R. O. Donald and Marcus Shimski (1919). MRDS database stated accuracy for this location is 1,000 meters.
Mineralization is a vein deposit (Deposit Model code 273; USGS model code 36a; Deposit model name: Low-sulfide Au-quartz vein; Mark3 model number 27), with a vein 3 to 4 feet thick (1.22 meters), hosted in Late Permian slate. Local rocks include Paleozoic marine rocks, undivided, unit 4 (Western Sierra Nevada). Pt reported discovered in 1919. It was reported in 2 zones a few inches wide on both sides of a barren quartz vein. The report was unverified. The reported association was considered improbable by Bowen (1957), who thought that the minerals had been misidentified.
Workings include surface and underground openings with an overall depth of 12.19 meters, and comprised of a 40 foot shaft in 1920.
Production data are found in: Laizure, Clyde McK (1928).
A small amount of Au ore was produced in 1919, which ran $44/ton (period values).
Analytical data results: $90/ton Pt, $44/ton Au. Reported grade of 2.13 ounces/ton (73 ppm) Au and 0.81 ounce/ton (28 ppm) Pt.
