The current Energy Fuels Henry Mountains Complex consists of the currently inactive Tony M mine and deposit, collectively known as the former Tony M property, and the Southwest, Copper Bench, and Indian Bench deposits, collectively known as the Bullfrog Property.

In October 2021, Consolidated Uranium Inc. (CUR) acquired the Tony M property and Southwest deposit from EFR. The remaining deposits (Copper Bench and Indian Bench) that occur to the north as part of the historic Bullfrog property remains under EFR ownership.

  • Sandstone hosted


Summary:

Henry Mountains Basin, a subprovince of the Colorado Plateau physiographic province. The Henry Mountains Basin is an elongate north-south trending doubly plunging syncline in the form of a closed basin, flanked by the Monument Uplift to the southeast, Circle Cliffs Uplift to the southwest, and the San Rafael Swell to the north. The regional and local geology of the Henry Mountains Basin vanadium-uranium deposits has been the subject of intensive research by staff of the U.S. Geological Survey (USGS) as well as other workers, referenced below. The following descriptions follow Northrop and Goldhaber (1990).

Uranium mineralization on the Property is hosted by favorable sandstone horizons in the lowermost portion of the Salt Wash Member of the Jurassic age Morrison Formation, where detrital organic debris is present. Mineralization primarily consists of coffinite, with minor uraninite, which usually occurs in close association with vanadium mineralization. Mineralization occurs as intergranular disseminations, as well as coatings and/or cement on and between sand grains and organic debris. Vanadium occurs as montroseite (hydrous vanadium oxide) and vanadium chlorite in primary mineralized zones located below the water table (i.e., the northernmost portion of the Tony M deposit).

The vanadium content of the Henry Mountains Basin deposits is relatively low compared to many other Salt Wash hosted deposits on the Colorado Plateau. Furthermore, the Henry Mounta ........

Summary:

The current Energy Fuels Henry Mountains Complex consists of the currently inactive Tony M mine and deposit, collectively known as the former Tony M property, and the Southwest, Copper Bench, and Indian Bench deposits, collectively known as the Bullfrog Property. The Property, which will consist of the former Tony M property and the Southwest deposit, will be located in the southwest portion of the current Henry Mountains Complex, while the combined Copper Bench–Indian Bench uranium deposits, which will remain under Energy Fuels ownership, are located in the eastern and northern portions of the Henry Mountains Complex, respectively.

The former Tony M mine was designed as a random room and pillar operation with pillar extraction by a retreat system. The pillars are 136 ft by 136 ft and form a conventional room and pillar pattern.

The Tony M mine is accessed via a double entry system with two parallel declines spaced 50 ft apart on centres. The portals of the two 9 ft high by 12 ft wide main haulage ways are located on the northwesterly side of Shootaring Canyon near the south centre of Section 16 T35S R11E SLM with a sill elevation of approximately 4,546 feet above sea level (FASL). The declines follow a minus three percent grade (i.e., 3 ft/100 ft) along a trend of N22°W, and generally follow the long axis of the mineralized trend, extending approximately 10,200 ft from the portal. The declines intersected the natural water table approximately 5,300 ft ........
