Disclosure Of Nature Of Operations And Going Concern [Abstract]
NATURE OF OPERATIONS AND GOING CONCERN [Text Block]	1. NATURE OF OPERATIONS AND GOING CONCERN Lion Copper and Gold Corp. (together with its subsidiaries, " Lion CG Company TSXV The Company acquires its mineral properties through option or lease agreements and capitalizes all acquisition, exploration and evaluation costs related to the properties. The underlying value of the amounts recorded as mineral properties does not reflect current or future values. The Company's continued existence depends on discovering the economically recoverable mineral reserves and obtaining the necessary funding to complete the development of these properties. These consolidated financial statements are prepared on a going concern basis, which contemplates that the Company will be able to meet its commitments, continue operations and realize its assets and discharge its liabilities in the normal course of business for at least twelve months from December 31, 2021. The Company has incurred ongoing losses and expects to incur further losses in the advancement of its business activities. For the year ended December 31, 2021, the Company incurred a net loss of $3,024 and used cash in operating activities of $2,078. As at December 31, 2021, the Company had cash and cash equivalents of $842, working capital deficit of $522 and an accumulated deficit of $94,636. The Company continues to incur losses, has limited financial resources and has no current source of revenue or cash flow generated from operating activities. To address its financing requirements, the Company plans to seek financing through, but not limited to, debt financing, equity financing and strategic alliances. However, there is no assurance that such financing will be available. If adequate financing is not available or cannot be obtained on a timely basis, the Company may be required to delay, reduce the scope of or eliminate one or more of its exploration programs or relinquish some or all of its rights under the existing option and acquisition agreements. The above factors give rise to material uncertainties that may cast significant doubt on the Company's ability to continue as a going concern. If the going concern assumptions were not appropriate for these consolidated financial statements, then adjustments would be necessary to the carrying values of assets, liabilities, the reported expenses and the consolidated statement of financial position classifications used. Such adjustments could be material.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2021
Disclosure Of Significant Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES [Text Block]	3. SIGNIFICANT ACCOUNTING POLICIES a) The preparation of the consolidated financial statements in conformity with IFRS 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 the consolidated financial statements of changes in such estimates in future periods could be significant. Actual results could differ from those estimates. A key source of estimation uncertainty that has a significant risk of causing material adjustment to the amounts recognized in the consolidated financial statements exists in relation to share-based compensation: 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 8 and include expected volatility, expected life of the options and number of options expected to vest. 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; and • Taxes: Judgement is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable income realized, including the usage of tax planning strategies. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. b) The functional currency for 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 (" $ USD In preparing the financial statements, transactions in currencies other than an entity's functional currency (" foreign currencies c) Direct costs related to the acquisition and exploration 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. Administration costs and general exploration 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, property water rights or cash proceeds received from farm-out option agreements are recorded as a reduction of the related mineral property, with any excess proceeds accounted for in the statements of loss and comprehensive loss. d) The Company's assets are reviewed for the indication of impairment at each reporting date in accordance with IFRS 6 - Exploration for and evaluation of mineral resources. If any such indication exists, an estimate of the recoverable amount of the asset is undertaken, being the higher of an asset's fair value, less costs of disposal and its value in use. If the asset's carrying amount exceeds its recoverable amount, an impairment loss is recognized in the statement of loss. Impairment indicators are considered to exist if (i) the right to explore the area has expired or will expire in the near future with no expectation of renewal; (ii) Substantive expenditure on further exploration for and evaluation of mineral resources in the area is neither planned nor budgeted; (iii) No commercially viable deposits have been discovered, and the decision had been made to discontinue exploration in the area; and (iv) Sufficient work has been performed to indicate that the carrying amount of the expenditure carried as an asset will not be fully recovered. An impairment loss is reversed if there is an indication that there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that this does not exceed the original carrying amount that if no impairment loss had been recognized. e) 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 the stock options are exercised, the value attributable to the stock options is transferred to share capital. f) Cash and cash equivalents consist of cash on hand, bank deposits and highly liquid investments with an original maturity of 90 days or less. g) Financial instruments are recognized in the statement of financial position 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: • at amortized cost, if they are held to collect contractual cash flows which solely represent payments of principal and interest; • at fair value, through other comprehensive income (" FVOCI • otherwise, they are classified at fair value through profit or loss (" FVPL 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 accounts payable approximate fair value due to their short-term nature. The marketable securities are a Level 1 fair value measurement; the derivative warrants are a Level 2 fair value measurement. The convertible note is classified as a liability at amortized cost, with the conversion feature classified as a derivative liability. The debt liability was initially recorded at fair value 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. h) 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, 2021 and 2020. i) 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. j) 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 or substantively 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 probable. k) IAS 12 Income Taxes On May 7, 2021, IASB issued amendments to IAS 12 which require companies to recognize deferred tax on transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences. The amendments are effective for annual reporting periods beginning on or after 1 January 2023. The impacts of the above amendments to IAS 12 on the Company's consolidated financial statements have not yet been evaluated.

It has an option to earn a 100% interest in the Bear, Wassuk, and Butte Valley properties in Nevada, a 100% interest in the Blue Copper Project in Montana, and a 90% interest in the Groundhog property in Alaska. a) On February 24, 2021, the Company announced a purchase and sale agreement to sell certain primary groundwater rights to Desert Pearl Farms LLC (" Desert Pearl Purchase and Sale Agreement NDWR Change Application On July 23, 2021, the Company received a notice from the State of Nevada that three water rights permits had been forfeited. Further, that the application for an extension of time to prevent forfeiture of a fourth certificate was denied. The permits affected are components of the Purchase and Sale Agreement announced on February 24, 2021. On August 20, 2021, the Company filed a Petition for Judicial Review of the Forfeiture Notice and has retained legal counsel to initiate and vigorously undertake the appeal process. Should the appeal be unsuccessful or Desert Pearl elects to terminate the Purchase and Sale Agreement, the Company will be obligated to refund the $1,000 initial payment to Desert Pearl (therefore, it has been treated as an accrued liability on the balance sheet) and the $1,910 balance of the water rights proceeds would be forfeited. b) The Company has five option agreements, entered from March 2013 to May 2015, to acquire a 100% interest in private land in Yerington, Nevada, known as the Bear deposit. Under the terms of these option agreements, as amended, the Company is required to make $5,673 in cash payments over 15 years ($5,029 paid) to maintain the exclusive right to purchase the land, mineral rights, and certain water rights and to conduct mineral exploration on these properties. Two of the properties are subject to a 2% NSR upon commencing commercial production, which can be reduced to a 1% NSR in consideration of $1,250 total. Outstanding payments due under the five option agreements by year are as follows: • $193 due in 2021 (paid); • $193 due 2022; • $201 due in 2023; • $50 due in years 2024 to 2028. c) The Wassuk property consists of 310 unpatented lode claims totaling approximately 6,400 acres on lands administered by the BLM. The Company has completed all requirements to earn a 100% interest in certain unpatented mining claims in Lyon County, Nevada, ($1,405 in cash payments and a work commitment of $50) and is in the process of exercising its option to purchase these claims. During 2021 two final option payments of $125 due by August 1, 2021, and the final $125 due by October 10, 2021, were both paid and form part of the total payments of $1,405.

FINANCIAL INSTRUMENT RISKS

FINANCIAL INSTRUMENT RISKS	12 Months Ended

Disclosure Of Financial Instrument Risk [Abstract]
FINANCIAL INSTRUMENT RISKS [Text Block]	15. FINANCIAL INSTRUMENT RISKS The board of directors has overall responsibility for establishing and oversight of the Company's risk management framework. The Company examines the various financial instrument risks to which it is exposed and assesses the impact and likelihood of those risks. Financial instruments consist of cash and cash equivalents, marketable securities, accounts payable and derivative liabilities. Financial instruments recorded at fair value on the consolidated statements of financial position are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The three levels of the fair value hierarchy are: • Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and • Level 3 - Inputs that are not based on observable market data. The Company's activities expose it to financial risks of varying degrees of significance, which could affect its ability to achieve its strategic objectives for growth and shareholder returns. The principal financial risks to which the Company is exposed are, liquidity risk, currency risk, interest rate risk, credit risk and commodity price risk. The Board of Directors has overall responsibility for the establishment and oversight of the Company's risk management framework and reviews the Company's policies on an ongoing basis. a) Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk through the management of its capital structure. To mitigate this risk, the Company has a planning and budgeting process in place to determine the funds required to support its ongoing operations and capital expenditures. The Company ensures that sufficient funds are raised from equity offerings or debt financings to meet its operating requirements, after considering existing cash and expected exercise of stock options and share purchase warrants. See Note 1 for further discussion. b) Currency risk Foreign exchange risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. The Company operates in the United States and Canada; therefore, it is exposed to currency risk from transactions denominated in CAD. Currently, the Company does not have any foreign exchange hedge programs and manages its operational CAD requirements through spot purchases in the foreign exchange markets. Based on CAD financial assets and liabilities' magnitude, the Company does not have material sensitivity to CAD to USD exchange rates. c) Interest rate risk Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in market interest rates. The Company is exposed to the interest rate risk on its liabilities through its outstanding borrowings and the interest earned on cash balances. The Company monitors its exposure to interest rates and maintains an investment policy that focuses primarily on the preservation of capital and liquidity. d) Credit risk is the risk of a financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company is exposed to credit risk through its cash and cash equivalents. Cash and cash equivalents are held in large Canadian financial institutions that have high credit ratings assigned by international credit rating agencies. e) The Company is exposed to market risk because of the fluctuating values of its publicly traded marketable securities. The Company has no control over these fluctuations and does not hedge its investments. Marketable securities; if any, are adjusted to fair value at each reporting date.

Disclosure Of Significant Accounting Policies [Abstract]
Accounting estimates and judgments [Policy Text Block]	a) The preparation of the consolidated financial statements in conformity with IFRS 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 the consolidated financial statements of changes in such estimates in future periods could be significant. Actual results could differ from those estimates. A key source of estimation uncertainty that has a significant risk of causing material adjustment to the amounts recognized in the consolidated financial statements exists in relation to share-based compensation: 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 8 and include expected volatility, expected life of the options and number of options expected to vest. 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; and • Taxes: Judgement is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable income realized, including the usage of tax planning strategies. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.
Translation of foreign currencies [Policy Text Block]	b) The functional currency for 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 (" $ USD In preparing the financial statements, transactions in currencies other than an entity's functional currency (" foreign currencies
Mineral properties [Policy Text Block]	c) Direct costs related to the acquisition and exploration 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. Administration costs and general exploration 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, property water rights or cash proceeds received from farm-out option agreements are recorded as a reduction of the related mineral property, with any excess proceeds accounted for in the statements of loss and comprehensive loss.
Impairment [Policy Text Block]	d) The Company's assets are reviewed for the indication of impairment at each reporting date in accordance with IFRS 6 - Exploration for and evaluation of mineral resources. If any such indication exists, an estimate of the recoverable amount of the asset is undertaken, being the higher of an asset's fair value, less costs of disposal and its value in use. If the asset's carrying amount exceeds its recoverable amount, an impairment loss is recognized in the statement of loss. Impairment indicators are considered to exist if (i) the right to explore the area has expired or will expire in the near future with no expectation of renewal; (ii) Substantive expenditure on further exploration for and evaluation of mineral resources in the area is neither planned nor budgeted; (iii) No commercially viable deposits have been discovered, and the decision had been made to discontinue exploration in the area; and (iv) Sufficient work has been performed to indicate that the carrying amount of the expenditure carried as an asset will not be fully recovered. An impairment loss is reversed if there is an indication that there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that this does not exceed the original carrying amount that if no impairment loss had been recognized.
Share-based compensation [Policy Text Block]	e) 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 the stock options are exercised, the value attributable to the stock options is transferred to share capital.
Cash and cash equivalents [Policy Text Block]	f) Cash and cash equivalents consist of cash on hand, bank deposits and highly liquid investments with an original maturity of 90 days or less.
Financial instruments [Policy Text Block]	g) Financial instruments are recognized in the statement of financial position 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: • at amortized cost, if they are held to collect contractual cash flows which solely represent payments of principal and interest; • at fair value, through other comprehensive income (" FVOCI • otherwise, they are classified at fair value through profit or loss (" FVPL 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 accounts payable approximate fair value due to their short-term nature. The marketable securities are a Level 1 fair value measurement; the derivative warrants are a Level 2 fair value measurement. The convertible note is classified as a liability at amortized cost, with the conversion feature classified as a derivative liability. The debt liability was initially recorded at fair value 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.
Provisions [Policy Text Block]	h) 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, 2021 and 2020.
Earnings (loss) per share [Policy Text Block]	i) 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]	j) 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 or substantively 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 probable.
Accounting Standards Issued but Not Yet Effective [Policy Text Block]	k) IAS 12 Income Taxes On May 7, 2021, IASB issued amendments to IAS 12 which require companies to recognize deferred tax on transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences. The amendments are effective for annual reporting periods beginning on or after 1 January 2023. The impacts of the above amendments to IAS 12 on the Company's consolidated financial statements have not yet been evaluated.
