Geologic setting

Geologic description

Color anomaly 1.0 by 0.5 mi (1,600 by 800 m) elongate in northwest direction. Anomaly is in volcanic and epiclastic rocks intruded by granodiorite. Disseminated pyrite is source of color anomaly.

Mineral deposit model Copper porphyry, epithermal gold vein
Mineral deposit model number 17, 25
Age of mineralization Miocene or younger
Alteration of deposit Propylitic based on presence of chlorite.

Production and reserves

Workings or exploration Brief reconnaissance geologic mapping and collection of a few silt samples reported by Christie (1974). Samples showed moderate silver (up to 1.5 ppm) and gold to 0.03 ppm. Copper, molybdenum, and zinc were all at low levels.
Indication of production None
