Comments on the site identification

  • South Mountain formerly known as Top of the World. (Top of the World was also in MAS, but as of 14-JUL-10 was not in newMRDS). At some point the records were probably recognized as duplicates and consolidated.

Ownership information

  • Type Operator

Comments on the workings information

  • "Phosphate Fertilizer, Inc., of Kemmerer operated an underground phosphate mine on Commissary Ridge during 1948-1949. The company installed a mill with a capacity of 200 tons of phosphate rock per day." (WGS Bull. 50, p. 147). Said mill, was probably in the flat spot just below the location of the now reclaimed adit on the 1985 provisional 24k Sublet topo.

General comments

Subject category Comment text
Deposit Mine is a Phosphate deposit but there are reports of uraniferous phosphate in the Meade Peak Member of the Phosphoria Formation.
General Entire area has been completely reclaimed, probably in the past decade (as of site visit by Wilson and Heran, USGS, 7-Aug-2010). Only hints remain of the dump at the adit on the topo. Upper slopes have been graded and reseeded.
