Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Location): Location given in original record as R91W, but in TEI-440 as R92W.

Comment (Deposit): Quoted from TEI-440: "This locality is in NW1/4NW1/4SE1/4, sec. 2, T35N, R92W. A uranium mineral similar to schroeckingerite occurs in coarse-grained arkosic gray sandsstone with a clayey matrix in the Tepee Trail (?) formation. The most radioactive spot is about 3 feet above the overlap content of this formation on brown coarse-grained granite, about 50 feet west of a small reservoir. The sandstone contains much black earthy material and sparse small pockets of a brilliant green fluorescent crystalline mineral that is probably schroeckingerite. A scintillation counter shows a maximum of 3 mr/hr in the vicinity of the pockets of uranium mineral."
