The Pinyon Plain Project (the name of the Canyon Mine was changed to the Pinyon Plain Mine in 2020.) is a fully-permitted uranium project with all surface facilities and a shaft in place.
During 2021, a water treatment plant was installed to process water for offsite transport. The water treatment plant was commissioned in April 2021.
In 2022, the Company plans to maintain the Pinyon Plain Project in compliance with all applicable permits as well as conduct engineering work that needs completed prior to restart of mining activities. The timing of the Company’s plans to extract and process mineralized material from the Pinyon Plain Project will be based on market conditions, available financing, and sales requirements. |

Summary:
The surface expression of the Canyon pipe is a broad shallow depression in the Permian Kaibab Formation. The pipe is essentially vertical with an average diameter of less than 200 ft., but it is considerably narrower through the Coconino and Hermit horizons (80 ft.). The cross sectional area is approximately 20,000 ft.2 to 25,000 ft.2. The pipe extends for at least 2,300 ft. vertically from the Toroweap limestone to the upper Redwall horizons. The ultimate depth of the pipe is unknown. Uranium mineralization is concentrated in an annular ring within the breccia pipe.
The Canyon Mine breccia pipe is surrounded by bleached zones, particularly notable in the Hermit Formation where unaltered red sediments contrast sharply with grey-green bleached material. Bleaching is common within 100 ft. of the pipe boundary. Sulphide mineralization, commonly pyrite, is found as streaks or blebs within the bleached zones.
Mineralization extends vertically both inside and outside the pipe over about 1,700 vertical ft., but high grade mineralization has been found mainly in the collapsed portions of the Coconino, Hermit, and Esplanade horizons and at the margins of the pipe in fracture zones. Sulphide zones are found scattered throughout the pipe but are especially concentrated (within a sulphide cap) near the Toroweap-Coconino contact, where the cap averages 20 ft. thick and consists of pyrite and bravoite, an iron-nickel sulphide. The ore assemblage consists of uranium- ........
Summary:
The Pinyon Plain Project is a fully constructed and partially developed underground uranium project with a head frame, a hoist, a compressor and a completed shaft.
At the Pinyon Plain Project, all surface facilities are in place. During 2017, an underground drilling program was completed, shaft sinking continued, and a large water tank was installed. The shaft sinking was completed by mid-March 2018. The depth of the shaft is approximately 1,470 feet below ground surface. Shaft stations are developed at depths of 1,000 feet (elevation 5,506 feet above sea level), 1,220 feet (elevation 5,286) and 1,400 feet (elevation 5,106).
