A Au-Cu property located in sec. 11, T4S, R21E, 3 miles SW of Bylas on the flank of Mount Turnbull. Discovered July 1, 1920, by B.F. Biker & others.

Mineralization is an ore zone 6.1 meters wide, related to a medium- to fine-grained dioritic rock that is intrusive into granite, both rocks of unknown age and both faulted and fractured. The shaft was sunk on an outcrop of chloritized dioritic rock cut by narrow fractures along which are scattered grains of quartz and sulfides.

Workings include a 100 foot (30.48 meters) deep shaft and 2 shallow cuts. No production.
