United States Department of the Interior, Geological Survey Bulletin 922-Q, 1941, ppgs. 513 & 514 : The Western Tungsten Company Mine, formerly the Pacific Tungsten Company, is developed by an adit 170 feet long, 270 feet of drifts, a small glory hole and numerous raises. The ore body has decreased in length from 200 feet at the surface to 80 feet at the adit level, about 80 feet below. In the adit the ore is 35 feet wide. The decrease in length is caused by the convergence of the granite contact, which dips 45 degrees south, with the north-dipping fault. Beyond this, no work has been done to the south. The ore body above the adit contains roughly 25,000 tons, the average grade of which is probably less than 0.5% of WO3. The depth to which the ore extends below the adit is unknown, although it is probably at least than 50 feet and may be 100 feet or more. The pendant apparently extends deeper than any other in the district.
