Exploratory Drilling Costs Capitalization and Impairment, Policy [Policy Text Block]	Exploration Stage We have established the existence of mineralized materials for certain uranium projects, including our Palangana and Christensen Ranch Mines (collectively, the “ISR Mines”). We have not established proven or probable reserves, as defined by the United States Securities and Exchange Commission (“SEC”) subpart 1300 of Regulation S-K (“S-K 1300”), through the completion of a “final” or “bankable” feasibility study for any of our uranium projects, including our ISR Mines. Furthermore, we have no plans to establish proven or probable reserves for any of our uranium projects for which we plan on utilizing in-situ recovery (“ISR”) mining, such as our ISR Mines. As a result, and despite the fact that we commenced extraction of mineralized materials at our ISR Mines, we remain an Exploration Stage company, as defined by the SEC, and will continue to remain as an Exploration Stage company until such time proven or probable reserves have been established. Beginning with our Annual Report on Form 10-K for Fiscal 2022, we report our mineral holdings in accordance with the SEC’s S-K 1300. Since we commenced extraction of mineralized materials at our ISR Mines without having established proven or probable reserves, any mineralized materials established or extracted from our ISR Mines should not in any way be associated with having established or produced from proven or probable reserves. In accordance with U.S. GAAP, expenditures relating to the acquisition of mineral rights are initially capitalized as incurred while exploration and pre-extraction expenditures are expensed as incurred until such time as we exit the Exploration Stage by establishing proven or probable reserves. Expenditures relating to exploration activities, such as drill programs to establish mineralized materials, are expensed as incurred. Expenditures relating to pre-extraction activities, such as the construction of mine wellfields, ion exchange facilities and disposal wells, are expensed as incurred until such time that proven or probable reserves are established for that project, after which expenditures relating to mine development activities for that particular project are capitalized as incurred. Companies in the Production Stage, as defined by the SEC, having established proven and probable reserves and exited the Exploration Stage, typically capitalize expenditures relating to ongoing development activities, with corresponding depletion calculated over proven and probable reserves using the units-of-production method and allocated to future reporting periods to inventory and, as that inventory is sold, to cost of goods sold. We are in the Exploration Stage which has resulted in our Company reporting larger losses than if it had been in the Production Stage due to the expensing, instead of capitalization, of expenditures relating to ongoing mine development activities. Additionally, there would be no corresponding depletion allocated to future reporting periods of our Company since those costs would have been expensed previously, resulting in both lower inventory costs and cost of goods sold and results of operations with higher gross profits and lower losses than if we had been in the Production Stage. Any capitalized costs, such as expenditures relating to the acquisition of mineral rights, are depleted over the estimated extraction life using the straight-line method. As a result, our consolidated financial statements may not be directly comparable to the financial statements of companies in the Production Stage.

Exploration Stage

We have established the existence of mineralized materials for certain uranium projects, including our Palangana and Christensen Ranch Mines (collectively, the “ISR Mines”). We have not established proven or probable reserves, as defined by the United States Securities and Exchange Commission (“SEC”) subpart 1300 of Regulation S-K (“S-K 1300”), through the completion of a “final” or “bankable” feasibility study for any of our uranium projects, including our ISR Mines. Furthermore, we have no plans to establish proven or probable reserves for any of our uranium projects for which we plan on utilizing in-situ recovery (“ISR”) mining, such as our ISR Mines. As a result, and despite the fact that we commenced extraction of mineralized materials at our ISR Mines, we remain an Exploration Stage company, as defined by the SEC, and will continue to remain as an Exploration Stage company until such time proven or probable reserves have been established.

Beginning with our Annual Report on Form 10-K for Fiscal 2022, we report our mineral holdings in accordance with the SEC’s S-K 1300.

Since we commenced extraction of mineralized materials at our ISR Mines without having established proven or probable reserves, any mineralized materials established or extracted from our ISR Mines should not in any way be associated with having established or produced from proven or probable reserves.

In accordance with U.S. GAAP, expenditures relating to the acquisition of mineral rights are initially capitalized as incurred while exploration and pre-extraction expenditures are expensed as incurred until such time as we exit the Exploration Stage by establishing proven or probable reserves. Expenditures relating to exploration activities, such as drill programs to establish mineralized materials, are expensed as incurred.
