The Cometoite #1 East Mine is a uranium mine located in Emery county, Utah at an elevation of 4,321 feet.

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.

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.

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 (Development): L60 - ECONOMIC STUDY (1957), L70 - ECONOMIC STUDY (1975 - 76)

Comment (Location): MORE EXACT MERIDIAN LOCATION NW 1/4 SW 1/4 SW 1/4 SEC. 36, T22S, R14E.

Comment (Production): URANIUM PRODUCTION - ITEM G7A IS ESTIMATED FROM A TOTAL PRODUCTION FIGURE FOR 3 MINES

Comment (Deposit): THE DEPOSITS ARE USUALLY ELONGATE ALONG CHANNEL SANDSTONE DEPOSITS

Comment (Geology): MINERALIZATION IS LARGELY CONFINED TO PALEOCHANNELS AND IS CLOSELY RELATED TO PLANT REMAINS, WHICH HAVE BEEN PARTIALLY OR WHOLLY REPLACED BY URANIUM AND/OR VANADIUM MINERALS.
