Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation These unaudited consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the SEC applicable to interim financial information and should be read in conjunction with the consolidated financial statements and notes thereto and the summary of significant accounting policies included in the Company’s Annual Report for the year ended December 31, 2025, which was filed with the SEC on March 31, 2026. The Company has prepared its consolidated financial statements in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) for all periods presented. In management’s opinion, the consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of the Company’s financial position and operating results. The results for the three and six months ended June 30, 2026 are not necessarily indicative of the results to be expected for the twelve months ending December 31, 2026. These financial statements are presented in thousands of United States Dollars (“USD”) unless otherwise noted. There are certain disclosures where the Company discloses the amount in Canadian Dollars (“CAD,”) if this is the currency in which the instrument is denominated. Principles of Consolidation These financial statements incorporate the financial statements of the Company and its controlled subsidiaries. The Company consolidates entities that it controls due to ownership of a majority voting interest and consolidates variable interest entities (“VIEs”) when it is the primary beneficiary. All intercompany transactions and balances have been eliminated. The Company has a 70% interest in the Alta Mesa Central Processing Plant (“CPP”) and Wellfield project (“Alta Mesa” or the “Alta Mesa Project”) with Boss Energy Limited (“Boss” or “Boss Energy”) owning the remaining 30%. The Company retained control after Boss acquired its interest in February 2024. Alta Mesa is considered a VIE, with the Company being considered the primary beneficiary. As a result, the Company consolidates the operations of Alta Mesa with an offsetting non-controlling interest being recorded. Non-controlling interests represent the portion of their equity which is not attributable, directly or indirectly, to the Company. The net income and equity attributable to Alta Mesa have been reported separately as required by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reported periods. Areas requiring significant judgments, estimates, and assumptions include the valuation of acquired mineral rights and properties, equity-method accounted investments, existence of impairment indicators for the Company’s long-lived assets, valuation and measurement of impairment losses on mineral rights and properties, valuation of asset retirement obligations, and valuation of stock options, share purchase warrants and share-based compensation. Other areas requiring estimates include depletion and amortization of mineral rights and properties and depreciation of property, plant and equipment. Actual results could differ significantly from those estimates and assumptions. Equity Method Investments Investments in an entity in which our ownership is greater than 20% but less than 50%, a 50/50 joint venture which the Company does not control, or an entity where other facts and circumstances indicate that we have the ability to exercise significant influence over its operating and financing policies, are accounted for using the equity method in accordance with FASB ASC Topic 323, Investments – Equity Method and Joint Ventures. The Company accounts for equity method investments over which the Company exerts significant influence, but not control, over the financial and operating policies through the fair value option of FASB ASC Topic 825, Financial Instruments. The fair value of the investee’s common shares is measured based on its closing market price. Subsequent to initial recognition, equity method investments are measured at fair value and changes therein are recognized as a component of gain (loss) on marketable securities, unrealized in the unaudited consolidated statements of operations. Revenue Recognition and Accounts Receivables Our revenues are primarily derived from the sale of uranium concentrates under contracts with major U.S. utilities. Revenue is recognized when delivery is evidenced by book transfer at the applicable uranium storage facility. The sales contracts specify the quantity to be delivered, the price, payment terms and the year of the delivery. Under these contracts, each product delivered to the customer represents a separate performance obligation. The Company's contracts with its customers include minimum quantities to be delivered over terms greater than one year and may include fixed prices, market-based prices, and other variable pricing. In many contracts the variable consideration is allocated entirely to a wholly unsatisfied performance obligation, having met the criteria to do so. Other contracts may require certain variable consideration to be estimated and constrained as part of the transaction price. Under the Company’s uranium contracts, it invoices customers after the performance obligations have been satisfied, at which point payment is unconditional. Accordingly, the Company’s uranium contracts generally do not give rise to contract assets or liabilities. The Company applies the optional exemption not to disclose the remaining transaction price that is variable and allocated to wholly unsatisfied future quantities. The Company expects to recognize revenue related to fixed and unconstrained variable consideration of $180,267 through December 31, 2029, and $128,615 thereafter under the non-cancelable portion of these contracts. Trade accounts receivables are recorded at the invoiced amount and do not bear interest. The Company evaluates its estimate of expected credit losses based on historical experience and current and forecasted future economic conditions for each portfolio of customers. As of June 30, 2026 and December 31, 2025, the Company did not have an allowance for expected credit losses for trade accounts receivable. As of June 30, 2026, the Company had no receivables from contracts with customers. As of December 31, 2025, the Company had $4,944 of receivables from contracts with customers. Recently Adopted and Issued Accounting Standards Recently Issued Accounting Standards In November 2024, the FASB issued Accounting Standards Update (“ASU’) 2024‑03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220‑40): Disaggregation of Income Statement Expenses. This ASU requires public business entities to disclose, in the notes to the financial statements, disaggregated information about certain expense categories included within income statement captions, without changing the presentation of the income statement. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASU on its unaudited consolidated financial statements and related disclosures, and we currently expect this ASU to have no impact to our results of operations, cash flows and financial condition. In December 2025, the FASB issued Accounting Standards Update ASU 2025‑12, Codification Improvements (Issue 4 - Calculation of Earnings per Share When a Loss from Continuing Operations Exists). This ASU clarifies the application of earnings per share (“EPS”) guidance when an entity reports a loss from continuing operations, including the interaction between basic and diluted EPS calculations in such circumstances. The amendments are intended to reduce diversity in practice without changing the underlying economics of EPS presentation. The guidance is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASU on its unaudited consolidated financial statements and related disclosures.
