Other/historical names associated with this locality:
Cabin shaft; Frontier Mine; Blanket vein
A former Pb-Au-Zn-U-Fe occurrence/mine located in the NW¼NE¼NW¼ sec. 18, T22N, R17W, G&SRM, on Bureau of Land Management administered land. Owned by Triangle Mining Company, Nevada (1956). Owned by Edwin White (1977). The USGS MRDS database stated accuracy for this locality is 100 meters.
BLANKET VEIN PROPERTY.
The Blanket Vein property is about half a mile southwest of the Gem mine, just below the mouth, of Charcoal Canyon. It is principally owned by the Golden Star Mining and Milling Company. The deposit is a gold-bearing quartz vein, resting on pre-Cambrian granite. It dips northeasterly at the low angle of about 30°, and is unique in being now bared, the granite having been completely removed from the upper surface by erosion over a nearly equidimensional area of about 500,000 square feet.
The vein is about 1 foot in average thickness and is said to contain about $8 in gold to the ton, or a total value of more than $90,000 for the area of the deposit thought to be in sight. Hornings and assays show portions of the deposit to contain as high as $20 in gold to the ton. The gold is mostly free milling. The quartz also contains some iron, principally hematite and limonite, derived from pyrite by oxidation.
