Location: This lode prospect is at an elevation of about 1,800 feet in locally-named Sargent Creek (Richter and Herreid, 1965). Sargent Creek was called Crevice Creek by Jasper (1953, 1956). The prospect is near the center of the N1/2 SW1/4 sec. 15, T. 12 S., R. 32 W., Seward Meridian. The prospect coincides with number 7 of Richter and Herreid (1965) and may correspond approximately wth locality 19 of Detterman and Cobb (1972). The location is accurate within 500 feet.
Geology: The country rocks at this prospect are chiefly intermediate and basic volcanic rocks of the Jurassic Talkeetna Formation (Richter and Herreid, 1965; Detterman and Reed, 1980). The deposit was largely snow covered when visited by Richter and Herreid, but they described dump samples of epidote-garnet tactite (skarn), garnet-magnetite skarn, massive magnetite, and massive magnetite-calcite rock. The samples were copper-stained, presumably by malachite and azurite, and contained chalcopyrite.
Workings: Test pits were largely snow covered when visited by Richter and Herreid (1965); the claim-owner (Sargent) reported good showings of disseminated chalcopyrite. The deposit was probably covered by the McNeil (IL043) claims.
Age: Probably Jurassic, the age of the nearby Pilot Knob granodiorite (IL041) (Richter and Herreid, 1965).
Alteration: Contact metasomatism. Oxidation of copper.
Commodities (Major) - Au, Cu, Fe; (Minor) - Ag
Development Status: None
Deposit Model: Fe skarn, Cu skarn (Cox and Singer, 1986; models 18d, 18b).
