A W-Au-Ag mine located on 12 unpatented claims in South-central sec. 30 & North-central sec. 31, T.23S., R.20E., in Bear Canyon on the SW side of the Huachuca Mountains; about 40 miles by road SW from Tombstone, and a short distance SW of the Harper prperty. Discovered 1905. First produced 1918. Owned/operated by H.G. Van Horn (1943).

Mineralization is several narrow quartz veins/stringers containing locally rich pockets of scheelite and minor spotty gold and silver values, cutting Cretaceous Bisbee Group sedimentary and volcanic rocks.

Workings are only shallow openings. Minor amounts of tungsten ore were produced during WWI and 25 to 30 units of tungsten concentrates were produced in 1943-1945.
