Location: This prospect is on the west flank of Michaels Sword at an elevation of 5,697 feet. It is near the NE corner of section 27, T.36 S., R.69 E. of the Copper River Meridian. The prospect was originally described in MAS/MILS record 0021130003. It is also listed as Alaska Kardex file number 113-009. This is location T001 of Wells and others (1986). The location is accurate within 1/4 mile.
Geology: This prospect is in the Coast Range plutonic-metamorphic complex which consists of high-grade schist and gneiss intruded by Cretaceous and Tertiary granodiorite. The metamorphic rocks are derived from volcanic, pelitic and minor carbonate strata of unknown protolith age (Brew and Ford, 1974, 1984). The rocks at this prospect include granodiorite, quartz monzonite, and alaskite, and pendants of Eocene pyroclastic volcanic rocks, minor sedimentary rocks, and hornfels derived from pelitic and intermediate to mafic volcanic and volcaniclastic rocks (Brew and Ford, 1985). Little is known about the prospect; the last reported activity was in 1957 (Wells and others, 1986). The commodities suggest it could be a lead-zinc replacement deposit.
Workings: The last reported activity was in 1957 (Wells and others, 1986).
Commodities (Major) - Pb, Zn
Development Status: None
Deposit Model: Possible polymetallic replacement deposit (Cox and Singer, 1986; model 19a)
