Other/historical names associated with this locality:
Snow Creek Uranium


Alteration: 5.48% U3o8 In One Sample

Geology: Quartz veins and pegmatite dikes cut granitic intrusive rocks in the area.


Structure: High Angle Ne Fault 2 Km Se Of Occurrence Steeply-Dipping Ene Shears And Alaskitic Dikes

Alteration: Argillic, Sericitic, And Silicification

Tectonics: Mobile Belt

Deposit: Steeply dipping veins and a possible manto. 3 areas of exposed uraniferous rock lie in a 150 m by 300 m area, elongates ene. The most easterly exposure is the largest (30 x 100 m) and consists of radioactive chalcedony which appears to form a shallowly-dipping mass. Radioactvivity is generally restricted to ene shears and irregular chalcedon masses. In one place, uranium is concentrated along limonitized fracture in an alaskite dike. The uranium was probably introduced, along with silica by hot water ascending along ene fracture. A line of presently active cold water springs is along strike west of the occurrences. The large easterly exposure may be sinter mound formed around an extinct hot spring.

Deposit type: Polymetallic veins

Development: Drilling project active in 1980's. Area is enclosed by the proposed blue lake primitive area.

Ore(s): Intrusive Contact?
