A former W occurrence/mine located in the NW¼ sec. 19, T30S, R41E, MDM, 1.3 km (0.8 mile) WSW of Atolia (N of the Union Mine). Owned by the American Gold and Tungsten Corporation. MRDS database stated accuracy for this location is 100 meters.
Mineralization is hosted in quartz monzonite. Local alteration includes pyritization, sericitization and the veins exhibit signs of carbonatization. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).
Workings include underground openings with an overall depth of 50.29 meters and comprised of the Top Notch shaft, inclined at 38 degrees N. Another shallow, inclined shaft was sunk on a vein 150 feet N of the Top Notch. Several other shafts were sunk on another vein that strikes N32Wa and dips 40 to 60NE.
Production data are found in: Lemmon, Dwight Moulton (unpublished).
Little scheelite was produced from the Top Notch shaft. No production figures are available.
