The Kermac is a uranium mine located in Fremont county, Wyoming.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Mineral Deposit Model
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.
