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 (Deposit): From TEI-440, p. 175 (quoted in its entirety because this is a difficult to find source): Kermac No. 1 claim This claim is in SE1/4NE1/4NW1/4, sec. 3, T39N, R92W. The uranium mineral is pale yellowish green, highly fluorescent, and was identified by L.B. Riley as metaautunite. The sample contained 0.59% eU and 0.80% U. The mineral is in the lower 10 to 20 feet of a 50-foot exposure of the upper Eocene (?) Tepee Trail (?) formation which was deposited in a valley cut in brown pre-Cambrian granite. No extensive exploration had been done at the time of the examination. The metaautunite occurs abundantly in pale green bentonitic plastic claystone and green bentonitic coarse-grained arkosic sandstone. Maximum radioactivity noted on the surface was 3 mr/hr.
