A former Au-Pb-Ag-Fe-Cu mine located in sec. 1, T22S, R45E, MDM, 4 miles S of Panamint, on National Park Service land (Death Valley National Park). Property consisted of 2 claims. MRDS database stated accuracy for this location is 10 meters.
In 1930 this gold mine was situated at the head of Happy Canyon, about four miles south of the Panamint City townsite.(Greene, Linda I. (1981): III.A.1.i.)(19))
Mineralization is a vein deposit hosted in conglomerate, schist and quartzite. The ore body is generally lenticular in form, strikes N25E and dips 50SE at a thickness of 9.14 meters. Controls for ore emplacement included the junctions of calcite stringers with quartz veins. There are a number of small veins, averaging 2 to 3 inches (5 to 7.5 cm) in thickness. According to the owner, the thicker veins are usually barren. They strike N35-50E and are apparently branches of the main vein, which was traceable for a short distance on surface. Calcite stringers join the main vein at acute angles and are confined to the footwall side. Post-mineralization faults of small displacement offset veins in many places. Hypogene minerals,. in order of abundance, include: Pyrrhotite, arsenopyrite, chalcopyrite, pyrite and gold. Local alteration included pyrrhotite metasomatically developed in wall rocks adjacent to the veins and replaces quartzite fragments in the country rock. Local rocks include Precambrian rocks, undivided, unit 1 (Death Valley).
Workings include surface and underground openings comprised of tunnels and a shaft plus many open cuts and trenches.
Production data are found in: Goodwin (1957).
A small amount of ore was produced in 1912 and ran 2.25% Pb and 14.0 ounces Ag/ton. The owner had fair returns and sold coarse gold specimens. Au averaged $9.00 per ton (period values).
