Geographic coordinates

Geographic coordinates: -144.20264, 62.85968 (WGS84)
Relative position 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).

Comments on the geologic information

  • Geologic Description = 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).
  • Ore Material = Uranium
  • Ore Material = thorium are concentrated in iron oxides
  • Age = Probably associated with emplacement of Richter's (1966) Permian or possibly Jurassic, diorite to quartz-diorite complex.
