Photo No. 45. No. 1 Shaft, Atolia Mining Company,Atolia, San Bernardino County. Black Hawk Tungsten Mine. This mine is situated in the Atoliadistrict, 1 mile east of town of Atolia. The holdings consist of 5 claims,known as the Halloran and Leonard group, one of which, a patentedclaim, is the only break in the continuity of the main group of theAtolia Mining Companys claim. The scheelite veins on these claimsare parallel and overlap each other, and are not continuous for anyconsiderable distance. The veins vary from mere seams up to 3 feet inwidth. The scheelite is associated with quartz and calcite. Veins strike10 degrees south of west and the dip varies from 20 degrees to 80degrees north. Veins occur in the granite. Developments consist ofthree shafts. Main working shaft was sunk to a vertical depth of 500feet, with idea of cutting the different parallel veins that were pro-ductive both east and west on the Atolia Mining Companys claim.
