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.

Land Status

Land ownership: BLM Administrative Area
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.

Comment (General): Laurence (Larry) P. James, Golden CO (visited USGS, Lakewood, April, 12, 2011) worked on this property. Suggests contacting Malcom Shannon, in Aurora CO, for more information.

Comment (Identification): West Alkali Creek is really the newer name, but no one knows it by that name.

Comment (Other Database): lists NRC Docket No. 40-9076.

Comment (Reserve-Resource): gives the following Reserves and Resources: Proven Reserves 1,323,000 tons U, Probable Reserves 653,000 tons U. Indicated Resources 1,623,000 tons U, Inferred Resources 420,000 tons U.

Comment (General): OPERATION SUSPENDED IN 1988.

Comment (General): Deleted MRDS record DE00263 (10021588) suggested that this was a past producer based on the comment "operation suspended in 1988). No proof that this was a productive mine.

Comment (Location): Location discrepancy. MINOBRAS clearly locates Bison Basin Project in Sec. 15, T26N, R96W in Sweetwater County, but this is not correct according to Larry James. Buffalo Basin itself is about 11 km (6 mi) to the NE of the coordinates given for this deposit. (p. 14 of 14), gives location of Bison Basin Project ISL as being in Fremont County. (Location given for Bison Basin mine, deleted MRDS record, was completely erroneous. Do not attempt to use that record to locate the mine.) In a visit by Laurence (Larry) James, to Anna Wilson on Jan. 31, 2012 at USGS, Larry located the Bison Basin on the Sulphur Bar Spring topo. It is clearly in Sec. 25, T97W, R27N. Many prospects shown on the topo in the SE4 of Sec. 25. Larry says at one time there was a power plant on the site, but it is fully reclaimed. Possibly just a concrete pier remains. Bison Basin is in Fremont County, not Sweetwater.
