The Project originally formed part of the Henry Mountains Complex, which consisted of the currently inactive Tony M mine and deposit, collectively known as the 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 remain under EFR ownership. |

Summary:
The Bullfrog Project consists of two separate contiguous deposits, also known as Copper Bench and Indian Bench.
The Copper Bench and Indian Bench Deposits are classified as sandstone hosted uranium deposits. Sandstone-type uranium deposits typically occur in fine to coarse grained sediments deposited in a continental fluvial environment. The uranium may be derived from a weathered rock containing anomalously high concentrations of uranium, leached from the sandstone itself or an adjacent stratigraphic unit. It is then transported in oxygenated groundwater until it is precipitated from solution under reducing conditions at an oxidation-reduction interface. The reducing conditions may be caused by such reducing agents in the sandstone as carbonaceous material, sulfides, hydrocarbons, hydrogen sulfide, or brines.
Uranium mineralization on the Bullfrog 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. Uranium 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.

Summary:
The Project originally formed part of the Henry Mountains Complex, which consisted of the currently inactive Tony M mine and deposit, collectively known as the Tony M property, and the Southwest, Copper Bench, and Indian Bench deposits, collectively known as the Bullfrog property.
The Project is currently in the resource delineation phase and EFR envisages this as an underground operation in which the ore will be processed at Energy Fuels' White Mesa Mill, 117 road miles (mi) away in Blanding, Utah. The Mill is on a reduced operating schedule while processing materials as they become available.
Based on the similarity of the Bullfrog deposit to other past producing uranium deposits in the Colorado Plateau and the Henry Mountain Mining District, the proposed mining methods at Bullfrog will include a combination of long-hole stoping, and a random room and pillar operation with pillar extraction by a retreat system.
