Description
George R. Simpson was issued Navajo Tribal Mining Permit No. 48 in the northwestern Carrizo Mountains, Apache County, Arizona on August 6, 1954. This permit was one mile square (Figure 1). On this permit, three uranium-vanadium mines were developed. Two and one-half years after the mines were closed and the mining permit cancelled, Gloria Emerson acquired Mining Permit No. 535 on August 25, 1961. This permit of 80 acres covered two of the Simpson mines in the southeast comer of former Mining Permit 48. A small amount of ore was mined from a trench south of one of the Simpson mines. This mine was called the Last Chance. In the official U.S. Atomic Energy Commission (AEC) ore production records (DOE, 1997) now available to the public at the National Archives, Rocky Mountain Region, Bloomfield, Colorado, the annual ore production from the Simpson mines and the Last Chance mine is mixed up. The purpose of this report is to record the correct ore production figures for all three Simpson mines and the Last Chance mine.
