Location and accuracy The Copper Kitty prospect is at an elevation of about 3,000 feet on the west wall of the valley of upper Copeland Creek. The map site is about 7 miles north of the junction of Copeland and Ohio creeks, in the Sw1/4 of sec. 29, T. 20 S., R. 11 W., of the Fairbanks Meridian. The location is accurate to within 0.5 mile. This is location E-28 of Balen (1990: OFR 34-90).

Geologic setting

Geologic description

The country rocks in the area of the Copper Kitty prospect are a tectonically mixed assemblage of Upper Devonian serpentinite, and subordinate basalt, chert, and gabbro. The deposit reportedly consists of pods of unspecified sulfide minerals, locally containing copper, gold(?) and silver (Balen, 1990: OFR 34-90). The hostrocks of the sulfide minerals also are not specified. Chromite apparently also occurs, presumably as magmatic segregations in the ultramafic rocks.

Mineral deposit model Podiform chromite?, Cyprus massive sulfide? (Cox and Singer, 1986; model 8a?, 24a?).
Mineral deposit model number 8a?, 24a?
Age of mineralization The (presumed) magmatic segregation are syngenetic with the Upper Devonian ultramafic host rocks.
