Geologic setting

Geologic description

Christie (1974) described a color anomaly associated with a weak gossan developed at the contact of a quartz diorite pluton with volcanic rocks of the Belkofski Formation. Volcanic rocks include andesitic crystal tuffs and flows. The area of gossan is a maximum of 5,000 by 3,000 ft (1,500 by 900 m) and shows disseminated pyrite mineralization, generally in trace amounts, but locally as high as 2 percent. Approximately half of the pyrite is fracture controlled in local zones of higher pyrite content.

Mineral deposit model Epithermal gold vein
Mineral deposit model number 25
Age of mineralization Pliocene or younger
Alteration of deposit Propylitic and argillic alteration reported along with weak leaching.

Production and reserves

Workings or exploration Brief reconnaissance geologic mapping and a few soil and silt samples. Gold, silver, and zinc were slightly anomalous, at 0.02, 1.4, and 104 ppm , respectively. Copper and molybdenum were at background levels.
Indication of production None

Additional comments

In Christie's (1974) evaluation, this occurrence had no sufficiently large covered area to hide a porphyry system and no copper mineralization was suggested.
