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.

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.

Comments
Comment (Production): "During the underground mine life from 1960 to 1963, approximately 99.8 kt (110,000 st) of ore was mined containing 544,311 kg (1.2 million lb) U3O8" (Ritchie, 1990, p. 1151) MS-94 credts this mine with total production of 7,170,586 short tons (6,505,046 mt).
Comment (Ownership): "In December, 1976,, Pathfinder Mines Corporation (knownw as Lucky Mc Uranium Corporation) was incorporated as a wholly owned subsidiary of Utah Internation Inc. [...]" (Ritchie, 1990)
Comment (Workings): Underground mine access was through a 12 ft diam. circular, concrete-lined, four-compartment vertical shaft 365 ft deep. The shaft was sunk in 1959. Development was by haulage drifts on the 6790 ft level at a dept of 324 ft, driven south and southwesternly along the trends of the 6780 ft and 6820 ft. roll front systems. (Ritchie, 1990, p. 1152) Operations converted to open-pit sometime after Nov. 1968 (Ritchie, 1990, p. 1154-1155). Mine was still active in 1983 when Ritchie wrote his paper for the 1990 volume (p. 1156)
Comment (Location): Corrected location from T27N to T28N as shown on pl. 7 (#2) in MINOBRAS, 1976. This location is for Utah Mines, which someone has coded as a synonym for this Shirley Basin mine. Verified location by comparing http://www.nrc.gov/info-finder/decommissioning/uranium/is-pathfinder-shirley-basin.pdf fig. 2 to current (2011) satellite imagery in ARC GIS.
