Mineralization involves a partially masked elliptical outcrop of tactite 350 feet long and 200 feet wide surrounded by granite, contains a little scheelite in irregular, narrow zones that trend E and W. Most of the tactite is barren; however, at the E edge is a single streak of high-grade ore 6 feet wide, 15 feet long and exposed to a depth of 10 feet. It appears under the ultra-violet lamp to contain about 5% WO3 and may amount to 90 tons. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).
