Location: The Snipe uranium-thorium prospect is at an elevation of 4,300 feet in an unnamed west-flowing tributary to the upper East Fork of Indian Creek. It is about 3.4 miles north of the west end of Long Lake in the SW1/4SW1/4, section 36, T. 13 N., R. 6 E., Copper River Meridian. The prospect is limited to a 30 foot by 50 feet outcrop in a stream cut. (WGM 1979).
Geology: The Snipe prospect is in a coarse-grained potassic-diorite phase of the Pennsylvanian to Permian, Ahtell pluton, possibly near a contact with the Grubstake quartz monzonite phase (Richter, 1966). The prospect consists of vuggy quartz-tourmaline vein material bordered by bleached, clay-rich alteration zones in Indian Creek quartz monzonite, a phase of the Ahtell pluton defined by WGM Inc. (1979). Scintillometer readings vary up to 3,500 cps (over 8 times background) and grab samples contain up to 730 ppm uranium and 8,650 ppm thorium (WGM Inc.,1979). The prospect is limited to a 30 foot by 50 feet outcrop in a stream cut. (WGM Inc., 1979).
Workings: Shallow hand trenching in three areas.
Age: Probably associated with emplacement of Richter's (1966) Permian or possibly Jurassic, diorite to quartz-diorite complex.
Alteration: Marked by pyrite, quartz, tourmaline, and sericitized plagioclase.
Commodities (Major) - Th, U
Development Status: None
