A former lode W occurrence/mine located in the SE¼NW¼ (estimated) sec. 33, T26S, R34E, 6.9 km (4.3 miles) SW of Weldon, at the mouth of Long Canyon. Produced during the periods of 1952, 1954 & 1955. MRDS database stated accuracy for this location is 100 meters.
The ore body is generally elongate, strikes N50W and dips steeply SW at a width of 3.05 meters and a length of 91.44 meters. The tactite body is bordered on the SW by coarsely crystalline, pale marble. It is 3 to 10 feet wide, is crudely layered, and nearly everywhere it contains closely spaced shears that trend parallel to the strike of the tactite body. Associated rocks include quartz monzonite. Local rocks include Quaternary alluvium and marine deposits.
Workings include underground openings comprised of 2 adits. The upper drift adit extends several tens of feet S40E, along the contact of marble and quartz monzonite on the NE side of the pendant. The lower adit is driven 50 feet NE.
Production data are found in: Troxel, Bennie Wyatt & P.K. Morton (1962).
Several units of W concentrates were recovered from the mined rock. Earlier history was not discovered.
