A former surface and underground Mn-W-Be-Li mine located on 3 unpatented lode claims in the SE¼ sec. 35, and in the SW¼SW¼SW¼ sec. 36, T8S, R22E, two miles NW of Battle Mountain on the SW slope of the Pinaleño Mountains, on National Forest land. Discovered by Mr. Lee in 1916 and re-discovered in 1952 by John Pospohola and A.A. Dankworth. Owned by W.L. Woodrow and M. Johnston of Arizona (1958); and by Mr. John Donowick of Arizona (1979). First produced 1955. Alternate coordinates provided: W 32°44'48"N, 109°14'23"W (places it in the Ask Peak District near the Greenlee Co. line. The primary coordinates provided in conjunction with the stated location in R22E indicate the location being in the Aravaipa District as stated.

Mineralization is a vein deposit associated with granite with seams and irregular veinlets of manganese minerals occurring in a vertical, N-trending fracture zone cutting volcanic rocks and schist. The ore zone is 60.96 meters long, with a depth to bottom of 12.19 meters, and a thickness of 1.22 meters, striking N53E and dipping steeply SE. Surface oxidation exists. Ore control was quartz veins cutting schist. Scheelite-bearing quartz veins cut Precambrian schists near a contact with Precambrian granite. At the SW corner of the opencut, a narrow dike of altered andesite cuts schist. Lime coats fractures in andesite.

M70 and M80 refer to the most heavily mineralized vein. Scheelite is sporadic but locally abundant in masses up to four inches in diameter. More tourmalinized veins strike N80E, dip 85 SE; strike N40W, dip 55 NE, and strike E-W, dip slightly N. The zone of scheelite-bearing veins is 25 feet wide, 200 feet long. Though some scheelite is found intermittantly over a distance of three miles.

Area structures include block faulting trending NNW. Regional trends: minor Pre-Cretaceous E- and NE-trending folds and major Post-Cretaceous NNW-trending faults; late Tertiary uplift and faulting. Area structures also include manganese deposits forming parallel seams and veinlets within the fracture zone with brecciated gangue; also steep northerly-trending zones of shearing and brecciation in volcanic rocks.

Workings include 1 opencut 12 by 50 feet and 15 feet deep; 2 small cuts, 1 shaft of unknown depth and a prospect trench 150 feet long. Production ceased after 1955. As of 1959 the following equipment was on the property: diesel generator, a 6 X 10 foot water tank, a jaw crusher, birating screens and a concentrating table.
