A former surface and underground W-Cu-Au-Ag-Mn mine located in sec. 21, T8S, R16E, in Tarr Wash, 2 miles NW of the former town of Tiger (Mammoth-St Anthony Mine) and about 5 miles north of Tarr's Camp and 11 miles NW of the town of Mammoth. Owned by M.G. Tarr. Produced until 1943. Additional location in the WΒ½ sec. 16. NOTE: The physical description of the mine's location is impossible. It can not be both 11 miles NW of Mammoth and 2 miles NW of the Mammoth-St Anthony Mine (Tiger), since Tiger is about 4 miles SW of Mammoth.
Mineralization is fine-grained, gneissic to schistose, brown porphyry that has undergone considerable hydrothermal and surface alteration. Cutting this formation are numerous north to NE fissures, of which some continuous quartz veins that range from seams to 6 inches (15 cm) wide. There are 7 quartz veins. Ore is in irregular stringers. Host rock unit is the Cloudburst Formation and Cretaceous or Tertiary latite flows thrust over Precambrian quartz monzonite. An associated rock unit is a quartz monzonite. Ore controls were faults. Area structures are block faulting trending NNW and regional trends of post-Cretaceous pre-Pliocene thrusts and high angle normal and reverse faults, plus Cretaceous-Tertiary intrusives and consequent faulting. A brecciated zone, identified by the presence of the 2 open pits, produced a small amount of scheelite and wolframite in quartz stringers
Workings include 1 vertical shaft several hundred feet deep, now inaccessible, and considerable lateral workings, and 2 shallow pits. There was some production.
