Economic information

Comments on the ore body information

  • Strathmore Minerals Corp. owns the Ketchum Buttes Property (no detailed information about the exact location or extent of their property as of 2006). They report a near surface uranium deposit with a planned conventional open-pit uranium mine in sandstone and conglomerate of the Miocene Browns Park Formation. Purchased from Pathfinder Mines Corp (part of AREVA (Cogma)). Historic non-43-101 compliant demonstrated resource of 1,135,000 tons @ 0.064% U3O8 containing 1,454,900 lbs (not tons) of U3O8.

Mining district

District name Ketchum Buttes uranium area

Production statistics

  • Year 2010
    Material 2061 short tons ore
    Ore mined 1869.7mt

Comments on the production information

  • According to the values reported on MS-94 (Gregory and others, 2010), the 2 productive mines in the district produced a total of 2061 tons of ore (not uranium). There is no mention of the ore grade, therefore total contained uranium can not be estimated. Ketchum Buttes produced 143 tons, Del Oro produced 2,048 tons.
