SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2023
Accounting Policies [Abstract]
Accounting estimates and judgments [Policy Text Block]	Accounting estimates and judgments The preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the application of policies, reported amounts and disclosures. By their nature, these estimates and judgments are subject to uncertainty and the effect on these consolidated financial statements of changes in such estimates in future years could be significant. Actual results could differ from those estimates. Key sources of estimation uncertainty that has a significant risk of causing material adjustment to the amounts recognized in the consolidated financial statements exist as follows: Share‐based payments: The Company has a stock option plan pursuant to which the fair value of options issued is estimated by using the Black Scholes option pricing model on the date of the grant based on certain assumptions. Those assumptions are described in Note 12 and include expected volatility, expected life of the options and number of options expected to vest. Investment in Associate: The Company received common shares of Falcon Butte Minerals Corp. during the year ended December 31, 2022 (Note 5). Due to Falcon Butte Minerals Corp. being a privately owned company, management estimated the value of the shares using the subscription price of units issued pursuant to a private placement completed on the same day as the transaction. Fair value of Simple Agreement for Future Equity ("SAFE") notes: During the year ended December 31, 2022, the Company entered into various SAFE agreements which are accounted for under ASC 480 which require revaluation to fair value. The determination of fair value was determined using valuation caps implicit to each SAFE agreement which required significant assumptions to be made by management. Valuation of warrants: During the year ended December 31, 2023 and 2022, the Company granted freestanding warrants pursuant to the closing of convertible debenture financings. The Black Scholes option pricing model was used to determine fair value for the warrants and required significant assumptions to be made by management. Valuation of derivative liabilities: During the year ended December 31, 2023 and 2022, the Company completed multiple tranches of convertible debenture financings. The convertible debentures include certain conversion features which were valued using the option pricing model and required significant assumptions to be made by management to value. Significant judgments used in the preparation of these consolidated financial statements include, but are not limited to: Mineral properties: Judgment is required in assessing whether certain factors would be considered an indicator of impairment. Both internal and external information is considered to determine whether there is an indicator of impairment present and, accordingly, whether impairment testing is required. Going concern: In the determination of the Company's ability to meet its ongoing obligations and future contractual commitments, management relies on the Company's planning, budgeting and forecasting process to help determine the funds required to support the Company's normal operations on an ongoing basis and its expansionary plans. The key inputs used by the Company in this process include forecasted capital deployment, results from operations, results from the exploration and development of its properties and general industry conditions; Influence over investment in associate: Classification of investments require judgment on whether the Company controls, has joint control or significant influence over the strategic, financial and operating decisions relating to the activity of the investee. In assessing the level of control or influence that the Company has over an investment, management considers ownership percentages, board representation as well as other relevant provisions in stockholder agreements; Valuation of the Arnold, Snowbird, and Montana property: During the year ended December 31, 2022, the Company entered into a property lease agreement with a related party. Management used judgment in determining the fair value of the leased property; and Control over FCC: During the year ended December 31, 2023, the Company's ownership in FCC decreased below 50%. Management has concluded that the Company still retains control over FCC as the Company has majority representation on the board of directors, and management of FCC and the Company is shared and will therefore consolidate FCC. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the year in which the estimates are revised and in any future years affected.
Investment in associate [Policy Text Block]	a) Investment in associate Investment in associate is comprised of the Company's investment in Falcon Butte Minerals Corp. ("Falcon Butte"). An associate is an entity over which the Company has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not in control or joint control over those policies. The Company's investment in Falcon Butte is accounted for using the equity method. Under the equity method, the investment in an associate or a joint venture is initially recognized at cost. The carrying amount of the investment is adjusted to recognize changes in the Company's share of net assets of the associate since the acquisition date. After application of the equity method, the Company determines whether a loss in the fair value of an investment below its carrying value is a temporary decline. If it is other than temporary, the investor calculates an impairment as the excess of the investment's carrying amount over the fair value. Reversals of impairments on equity method investments are prohibited. Upon loss of significant influence over the associate, the Company measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate upon loss of significant influence and the fair value of the retained investment and proceeds from disposal is recognized in profit or loss.
Translation of foreign currencies [Policy Text Block]	b) Translation of foreign currencies The functional currency for the Company and each of the Company's subsidiaries is the currency of the primary economic environment in which the entity operates. Determination of functional currency may involve certain judgments to determine the primary economic environment and the Company reconsiders the functional currency of its entities if there is a change in events and conditions that determined the primary economic environment. The Company's presentation currency is the U.S. dollar ("$" or "USD"). The functional currency of the Company and its significant subsidiaries is the USD. In preparing the financial statements, transactions in currencies other than an entity's functional currency ("foreign currencies") are recorded at the rates of exchange prevailing at the dates of the transactions. At each balance sheet date, monetary assets and liabilities are translated using the year‐end foreign exchange rate. Non‐monetary assets and liabilities are translated using the historical rate on the date of the transaction. All gains and losses on translation of these foreign currency transactions are included in the statement of loss.
Mineral properties [Policy Text Block]	c) Mineral properties Direct costs related to the acquisition of mineral properties held or controlled by the Company are capitalized on an individual property basis until the property transitions to the development stage, is sold, abandoned, or determined to be impaired. Exploration and administration costs are expensed as incurred. The Company classifies its mineral properties as exploration and evaluation assets until the technical feasibility and commercial viability of extracting a mineral resource are demonstrable. At this point, the mineral properties' carrying value is tested for impairment and subsequently transferred to property and equipment. The establishment of technical feasibility and commercial viability of a mineral property is assessed based on a combination of factors, such as the extent of established mineral reserves, the results of feasibility and technical evaluations, and the status of mineral leases or permits. Proceeds from the sale of properties are accounted for as reductions to the capitalized acquisition costs. Cash proceeds received from farm‐out option agreements are recorded as a liability once received and reduced as the obligation to incur expenditures related to the agreement are met. Funds received for expenditures incurred are recorded as an income in the consolidated statements of operations or as a reduction to the capitalized acquisition costs, depending on the nature of the expenditure incurred.
Impairment [Policy Text Block]	d) Impairment The Company assesses the carrying costs of the capitalized mineral properties for impairment indicators under ASC 360-10, "Impairment of long-lived assets". If impairment indicators are identified, the Company evaluates its carrying value under ASC 930-360, "Extractive Activities - Mining". An impairment is recognized if the sum of the expected undiscounted future cash flows is less than the carrying amount of the mineral properties. Impairment losses, if any, are measured as the excess of the carrying amount of the mineral properties over its estimated fair value. Based on the Company's evaluation, no impairment indicators were identified on the mineral properties for the years ended December 31, 2023 and 2022.
Share-based payments [Policy Text Block]	e) Share‐based payments The fair value of stock options granted to directors, officers, employees and consultants is calculated using the Black Scholes option pricing model and is expensed over the vesting periods. If and when stock options are exercised, the value attributable to the stock options is transferred to share capital.
Cash [Policy Text Block]	f) Cash Cash consists of cash on hand and bank deposits. As at December 31, 2023, the Company held $2 CAD (2022 - $15 CAD) in bank accounts denominated in CAD.
Financial instruments [Policy Text Block]	g) Financial instruments Financial instruments are recognized in the balance sheet when the Company becomes a party to a contractual obligation. At initial recognition, the Company classifies and measures its financial instruments as one of the following: held to maturity (amortized cost); available for sale (fair value through other comprehensive income); Fair value through other comprehensive income (FVOCI); otherwise, they are classified as trading (fair value through Profit and loss). Financial assets are classified and measured at fair value with subsequent changes in fair value recognized in either profit and loss as they arise unless restrictive criteria are met for classifying and measuring the asset at either amortized cost or FVOCI. Financial liabilities are measured at amortized costs unless they are elected to be or required to be measured at fair value through profit and loss. Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred, and the Company has transferred all risks and rewards of ownership. Financial liabilities are derecognized when the obligations specified in the contract are discharged, cancelled, or expire. The Company's cash, accounts payable, accrued liabilities and Rio Tinto deposit approximate fair value due to their short‐term nature. The convertible note is classified as a liability at amortized cost, with the conversion feature and related warrants classified as liabilities to be measured at fair value at each reporting period. The debt liability was initially recorded at the residual value after deducting the fair value of the conversion feature and warrants and is subsequently measured at amortized cost using the effective interest rate method and will be accreted to the face value over the term of the convertible debenture. The SAFE notes are classified as liabilities pursuant to ASC 480 and were measured at fair value at each reporting period, with changes in fair value recorded within the Consolidated Statements of Operations.
Provisions [Policy Text Block]	h) Provisions Provisions are recognized when a present legal or constructive obligation exists as a result of past events where it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and the amount of the obligation can be reliably estimated. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the reporting date, considering the risks and uncertainties surrounding the obligation. The Company had no material provisions as of December 31, 2023 and 2022.
SAFE Notes [Policy Text Block]	i) SAFE Notes The Company issued SAFE notes to investors during the year ended December 31, 2022 and determined that the SAFE notes are not a legal form of debt (i.e., no creditors' rights). The Company allowed for redemption based upon certain events that are outside of the control of the Company. Therefore, the SAFE Instruments were classified as liabilities pursuant to ASC 480 and were measured at fair value at each reporting period, with changes in fair value recorded within the Consolidated Statements of Operations. The safe notes were converted during the year ended December 31, 2023 due to a triggering event caused by a private placement from FCC and the SAFE notes were converted into common shares of FCC (Note 10).
Earnings (loss) per share [Policy Text Block]	j) Earnings (loss) per share Basic earnings (loss) per share is calculated using the weighted average number of common shares outstanding during the year. The Company uses the treasury stock method to compute the dilutive effect of options, warrants and similar instruments. Under this method, the dilutive effect on earnings per share is calculated, presuming the exercise of in‐the‐money outstanding options, warrants and similar instruments. It assumes that the proceeds of such exercise would be used to repurchase common shares at the average market price during the year. However, the calculation of diluted loss per share excludes the effects of various conversions and exercise of options and warrants that would be anti‐dilutive.
Income tax [Policy Text Block]	k) Income tax Income tax comprises current and deferred tax. Income tax is recognized in net loss, except to the extent it is related to items recognized directly in equity or other comprehensive loss. Deferred tax is recognized in respect of temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. Deferred tax is determined on a non‐discounted basis using tax rates and laws that have been enacted by the reporting date and are expected to apply when the deferred tax asset or liability is settled. Deferred tax assets are recognized to the extent that their recovery is more likely than not.
Non-controlling interest [Policy Text Block]	l) Non-controlling interest On December 13, 2022, Quaterra Alaska was issued 57,513,764 common shares of FCC which represented 79.3% of all issued and outstanding shares at December 31, 2022. For partially owned subsidiaries, the interest attributable to non-controlling shareholders is reflected in non-controlling interest. During the year ended December 31, 2023, FCC completed multiple financings throughout the year and at December 31, 2023, the Company held 47.7% (Note 19) of shares in FCC. In the absence of majority holdings, the Company will continue to consolidate FCC as it still has the control through its majority representation on the board of directors and its shared management with FCC (Note 7).
Asset retirement obligations [Policy Text Block]	m) Asset retirement obligations Liabilities for asset retirement obligations are recognized at the time of environmental disturbance, in amounts equal to the discounted value of expected future mine reclamation and closure costs. The provision for asset retirement obligations represents management's best estimate of the present value of the future cash outflows required to settle the liability. To the extent a legal obligation exists, an asset retirement obligation is recorded at its estimated fair value and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Because asset retirement obligations represent financial obligations to be settled in the future, uncertainties exist in estimating timing and amount of the associated costs to be incurred. As at December 31, 2023 and 2022, the Company does not believe it has any significant asset retirement obligations.
