Organization, Consolidation and Presentation of Financial Statements [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" or the "Company") is a Canadian-based Company advancing its flagship copper projects at Yerington, Nevada through an option to earn-in agreement with Rio Tinto. The Company is incorporated in British Columbia, Canada. Its registered and records offices are located at 1200 - 750 West Pender Street, Vancouver, British Columbia, Canada, V6C 2T8. On November 22, 2021, the Company changed its name from Quaterra Resources Inc. to Lion Copper and Gold Corp. The shares of the Company commenced trading under the new name at the open of trading on November 23, 2021. The Company's common shares are listed on the TSX Venture Exchange ("TSXV") under the symbol "LEO" and trade on the OTCQB Market under the symbol "LCGMF". The Company acquires its mineral properties through option or lease agreements and capitalizes all acquisition 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 economically recoverable mineral reserves and obtaining the necessary funding to complete the development of these properties. These condensed interim 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 the date of approval from the Board of Directors. The Company has incurred ongoing losses and expects to incur further losses in the advancement of its business activities. For the three months ended March 31, 2023 and 2022, the Company incurred a net loss of $2,116 (2022 - $1,405). As at March 31, 2023, the Company had cash of $10,597 (December 31, 2022 - $1,365), working capital deficit of $65 (December 31, 2022 - deficit of $556) and an accumulated deficit of $123,787 (December 31, 2022 - $121,834). 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 cast substantial doubt on the Company's ability to continue as a going concern. If the going concern assumptions were not appropriate for these condensed interim consolidated financial statements, then adjustments would be necessary to the carrying values of assets, liabilities, the reported expenses, and the condensed interim consolidated statement of financial position classifications used. Such adjustments could be material.

It was announced that more than 50% of the Company's common shares are held by U.S. stockholders, and the Company no longer meets the definition of a foreign private issuer under the United States securities laws. As a result, commencing in 2023, the Company is required to use forms and rules prescribed for U.S. domestic companies, including the requirement that condensed interim consolidated financial statements be presented in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") instead of International Financial Reporting Standards ("IFRS") as issued by the IAASB. The Company's common shares will continue to be listed on the TSX Venture Exchange and quoted on the OTCQB. These condensed interim consolidated financial statements have been prepared in accordance with U.S. GAAP. These condensed interim consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission (the "SEC"), effective for the three months ended March 31, 2023. Certain information or footnote disclosures normally included in condensed interim consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying condensed interim consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The accompanying condensed interim consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2022. The interim period results do not necessary indicate the results that may be expected for any other interim period or for the full fiscal year. Comparative figures, which were previously presented in accordance with IFRS as issued by the International Accounting Standards Board have been adjusted as necessary to be compliant with the Company's policies under U.S. GAAP. These condensed interim consolidated financial statements have been prepared on a historical cost basis except for certain financial instruments which are measured at fair value. In addition, these condensed interim consolidated financial statements have been prepared using the accrual basis of accounting, except for the cash flow information. The Company consolidates an entity when it has power over that entity, is exposed, or has rights, to variable returns from its involvement with that entity and can affect those returns through its control over that entity. All material intercompany transactions, balances and expenses are eliminated on consolidation. These condensed interim consolidated financial statements include the condensed interim consolidated financial statements of Lion Copper and Gold Corp., and its subsidiaries: Percentage ownership Subsidiaries March 31, 2023 December 31, 2022 Country of incorporation Quaterra Alaska Inc.

In early March 2021, the Company filed an application with the State of Nevada Division of Water Resources ("NDWR") to change the manner of use of the water rights from mining to agriculture and their place of use ("Change Application"). The Change Application was subsequently withdrawn on October 17, 2022. Under the terms of the Purchase and Sale Agreement, Desert Pearl made a $1,000 initial payment to the Company on March 5, 2021. On May 26, 2022, the company announced it had reached an amicable agreement with Desert Pearl Farms to terminate the contract on the sale of the Company's water rights. As a consequence of the termination, the Company will recover the water permit designated for mining and milling use. The $1,000 deposit has been returned to Desert Pearl Farms. This water permit is currently subject to court proceedings and settlement discussions between the Company and the State of Nevada, as discussed in the following paragraph. On July 23, 2021, the Company received a notice from the State of Nevada that three water rights permits had been forfeited. Further, the application for an extension of time to prevent forfeiture of a fourth certificate was denied. The Company is vigorously appealing the State's decision and hired legal counsel to challenge and reverse the State's decision. As discussed in the previous paragraph, one of the permits affected by the State's letter was subject to 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 vigorously undertake the appeal process. SPS subsequently filed and was granted a Stay of the Forfeiture Notice on September 15, 2021. SPS filed its Opening Brief on March 28, 2022. The State Engineer filed its Answering Brief on July 8, 2022. SPS filed its Reply Brief on August 25, 2022. A hearing regarding the status of the forfeiture appeal was held in the Third Judicial Court District in Lyon County on November 4, 2022. On December 6, 2022, the Judge remanded the case back to the State for further written findings based on issues raised at the hearing. The Company has not received a response from the State since the Remand Order was issued. Since receipt of the Forfeiture Notice, SPS has been in contact with the State Engineer's office in an attempt to resolve the Forfeiture Notice.

During the year ended December 31, 2021, the lease agreement was further extended from six to seven years, providing the Company more time to make the required exploration expenditures and lump sum payment. To earn the 90% interest, the Company must fund a total of $5,000 ($2,839 funded) of exploration expenditures and make a lump sum payment to Chuchuna of $3,000 by the end of April 20, 2024.

On April 5, 2022, the Company completed the assignment of the two option agreements for the Butte Valley Property and the Company received 16,049,444 common shares of Falcon Butte with a fair value of $1,906 and $500 cash for the property, resulting in a gain on sale of $2,207 (Note 5, 13). On April 13, 2022, the Company amended the agreement. Pursuant to the addendum Falcon Butte had the option to pay a total of $500 in exchange for a 0.5% buy-down and retirement of certain NSRs held by the Company. As of December 31, 2022, the Company has received the full consideration of $500, which is recorded as other income. On December 13, 2022, the Butte Valley Royalty rights were transferred from Quaterra Alaska to BCRC (Note 7). f) On August 25, 2021, the Company entered into a non-binding letter of intent (the "LOI") with Houston Minerals Ltd. ("Houston") setting forth the terms of an option whereby the Company may acquire a 100% interest in the Chaco Bear Property located directly east of the Golden Triangle of British Columbia, and the Ashton Property located near Lytton, British Columbia (Collectively, the "Properties"). f) Under the terms of the LOI, the Company and Houston proposed to enter into a definitive agreement whereby the Company can earn up to a 100% interest in the Properties by making the following issuances and payments over a four-year period: issuing 8,000,000 common shares of the Company on closing (issued on March 17, 2022); making annual lease payments on the Properties after 2021; incurring CAD$150 of exploration expenditures on the Chaco Bear Property and CAD$50 of exploration expenditures on the Ashton Property before the end of 2021 for CAD$200 (paid); incurring exploration expenditures of at least the value of the annual assessment multiplied by 1.5 for periods after 2021 (claims were renewed and extended through to early 2025, resulting in no obligation on exploration expenditures until 2024); paying CAD$1,500 for the Chaco Bear Property and CAD$1,000 for the Ashton Property on or before 4 years from the closing, which amounts are payable in cash or common shares of the Company; and making annual advance royalty payments in the fourth and fifth year from the closing in the amounts of CAD$250 on the Chaco Bear Property and CAD$150 on the Ashton Property. On September 17, 2021, the parties agreed to an amendment to the LOI to include a 2.5% NSR on each property. Prior to feasibility, the Company may reduce the NSR to 1.0% on the Chaco Bear Property in consideration for a payment of CAD$6,000 and 1.0% on the Ashton Property for a payment of CAD$3,000. Post feasibility, the Company may purchase the remaining 1.0% NSR on the Chaco Bear Property for CAD$12,000 and the remaining 1.0% NSR on the Ashton Property for CAD$6,000. On January 26, 2022, the Company entered into an option agreement with Houston Minerals Ltd. to replace the LOI dated August 25, 2021. Pursuant to the terms of the option agreement, the Company may acquire a 100% interest in the Chaco Bear Property located directly east of the Golden Triangle of British Columbia, and the Ashton Property located near Lytton, British Columbia, subject to a 2.5% net smelter returns royalty. The terms of the option agreement are unchanged from the LOI except that the term of the option has changed from a four year period to a ten year period and annual advance royalty payments in the amounts of CAD$250 on the Chaco Bear Property and CAD$150 on the Ashton Property are to be paid starting on the fifth year from closing through to the ninth year from closing instead of only in the fourth and fifth years from the closing. All other consideration terms remain unchanged. In addition, commencing on January 31, 2022, and on January 31 of each year thereafter during the Option Period, Lion CG shall pay the following option maintenance fees to Houston: (a) CAD$60 in respect of the Chaco Bear Property; and (b) CAD$40 in respect of the Ashton Property. The maintenance fee for the year ended December 31, 2023 has not been paid as of March 31, 2023 and the Company has until June 4, 2023 to procure the maintenance fee. Lion CG funded an initial work program in 2021 of CAD$200 on the Properties in consideration for the grant of the Option, and on March 16, 2022, the transaction was closed. The Company may exercise the Option for a period of up to ten years to acquire (i) the Chaco Bear property by paying CAD$1,500 to Houston, in cash or in common shares of the Company at the Company's option; and/or (ii) the Ashton Property by paying CAD$1,000 to Houston in cash or in common shares of the Company at the Company's option, and in either case common shares will be valued using the volume weighted average trading price of the Company's common shares for the twenty trading day period ending three trading days prior to the date of issuance of such Lion CG shares, with such cash payments being subject to a discount of between 5% and 15% based on the timing of exercise and cumulative exploration expenditures incurred as at the time of exercise. Houston will retain a 2.5% net smelter returns royalty on any of the Properties for which an Option has been exercised by the Company. g) During the year ended December 31, 2021, Blue Copper LLC acquired and staked a district scale exploration and resource discovery opportunity (the "Blue Copper Prospect"), comprising more than 7,430 acres in Powell County and Lewis & Clark County in Montana, USA. The area is prospective for high grade copper-gold skarns and porphyry copper-gold mineralization. The claim block encompasses a group of more than fourteen historic small mines that produced high grade gold, copper, and tungsten. As a part of the transaction, Blue Copper LLC entered into a purchase agreement with Four O Six Mining & Exploration LLC to acquire certain existing and additional unpatented mining claims. In exchange for the unpatented mining claims, as part of the closing of the transaction, the Company issued 1,500,000 common shares of the capital of the Company (Note 11) and provided a NSR of 2.0% with a buy-down of 1% NSR for 1,500. Blue Copper LLC has staked an additional 131 claims to expand the Blue Copper Prospect. The Company has provided a NSR of 2% with a buy-down of 1% NSR for $600 to Four O Six Mining & Exploration LLC for these claims. On February 14, 2022, as a part of the Blue Copper Prospect transaction, the Company issued 1,500,000 common shares as part of the closing of the transaction (Note 11). On December 13, 2022, Quaterra Alaska's interest in Blue Copper LLC was transferred to BCRC (Note 7). On October 28, 2022, prior to the transaction in Note 7, Blue Copper LLC entered into a mining lease agreement with Snowshoe Creek LLC ("Snowshoe"), a Montana limited liability company owned by the CEO of the of the Company. Pursuant to the Agreement, Snowshoe will lease the Arnold, Snowbird and Montana property, including the patented mining claims on such property, to Blue Copper LLC for a term of 20 years and extendable on sole discretion of Blue Copper LLC. Blue Copper LLC has the ability to extend the term in 12-month increments upon providing written notice no later than 180 days prior to the expiration of the current term. As consideration, 15,000,000 preferred stock in Blue Copper Resources Corp. was issued to the CEO of the Company. The transaction was measured using the fair value of the asset received as the cost was more clearly evident. The fair value of the asset received was calculated using the original cost incurred to acquire the property and was determined to be $500. h) During the three months ended March 31, 2023, the Company, through Blue Copper Resources Corp, incurred $99,000 in evaluation expenditures on these properties in order to determine whether they warranted further pursuit. i) On March 18, 2022, the Company entered into an Option to Earn-in Agreement with Rio Tinto America Inc. ("Rio Tinto") to advance studies and exploration at Lion CG's copper assets in Mason Valley, Nevada. Under the agreement, Rio Tinto has the option to earn a 65% interest in the assets, comprising 34,494 acres of land, including the historic Yerington mine, greenfield MacArthur Project, Wassuk property, the Bear deposit, and associated water rights (the "Mining Assets"). In addition, Rio Tinto will evaluate the potential commercial deployment of its Nuton™ technologies at the site. Nuton™ offers copper heap leaching technologies developed by Rio Tinto to deliver greater copper recovery from mined ore and access new sources of copper such as low-grade sulphide resources and reprocessing of stockpiles and mineralized waste. The technologies have the potential to deliver leading environmental performance through more efficient water usage, lower carbon emission, and the ability to reclaim mine sites by reprocessing waste. The stages of the Agreement are set out below. Stage 1 Rio Tinto will pay up to four million U.S. dollars ($4,000) for an exclusive earn-in option and agreed-upon Mason Valley study and evaluation works to be completed by Lion CG no later than December 31, 2022 (Note 6).

Stages 1 and 2 may be accelerated at Rio Tinto's option. Stage 3 - Feasibility Study Within sixty (60) days of the completion of Stage 2, Rio Tinto shall provide notice to Lion CG whether Rio Tinto will exercise its Option and fund a Feasibility Study based on the results of the Stage 1 and Stage 2 work programs. Rio Tinto will fully-fund the Feasibility Study and ancillary work completed by Lion CG in amount not to exceed fifty million U.S. dollars ($50,000). Investment Decision Upon completion of the Feasibility Study, Rio Tinto and Lion CG will decide whether to create an investment vehicle into which the Mining Assets will be transferred, with Rio Tinto holding not less than a 65% interest in the investment vehicle. • If Rio Tinto elects to not to create the investment vehicle, then Lion CG shall grant to Rio Tinto a 1.5% NSR on the Mining Assets. • If Rio Tinto elects to create the investment vehicle but Lion CG elects not to create the investment vehicle, then, at Rio Tinto's option, Lion CG shall create the investment vehicle and Rio Tinto will purchase Lion CG's interest in the investment vehicle for fair market value. Project Financing • • • On April 27, 2022, the Company TSX Venture Exchange approved the Company's Option to Earn-in Agreement with Rio Tinto America Inc. On May 15, 2022, Rio Tinto approved the Stage 1 Work Program and provided $4,000 to the Company for the development of the Mason Valley projects, which has been completed as of December 31, 2022. The remaining funds of the $4,000 will be spent per agreement with Rio Tinto in 2023 for Stage 2. (Note 6). On January 13, 2023, the Company reached an agreement with Rio Tinto on the scope of the Stage 2 Program of Work. As a result, the Company received $7,500, comprising of $5,000 for Stage 2 work and $2,500 as an immediate advance on part of the Stage 3 financing (Note 6).

Convertible Debt [Abstract]
CONVERTIBLE DEBENTURES [Text Block]	9. CONVERTIBLE DEBENTURES On June 17, 2022, the Company closed the first tranche of its non-brokered private placement of unsecured convertible debentures for gross proceeds of $1,075 (Note 12). The debentures bear interest at a rate of 14% per annum and mature on February 17, 2024 and are convertible into shares of the Company at $0.067 ($0.085 CAD) per share until June 17, 2023 and thereafter at $0.078 ($0.10 CAD) per share. The holder also has the option to elect at any time prior to the election date to be repaid by way of shares the Company owns of Falcon Butte (Note 5) at the rate of $0.25 per Falcon Butte share. In conjunction with the first tranche of the convertible debt financing, the Company issued 16,044,774 warrants. The warrants are exercisable into one common share of the Company at $0.067 ($0.085 CAD) per share and expire on February 17, 2024. The convertible debentures were determined to be a financial instrument comprising a host debt component, a conversion feature classified as a derivative liability, and freestanding warrants classified as a derivative liability. The warrants and conversion features were determined to be derivative liabilities because the exercise prices are denominated in both the functional currency of the Company and a foreign currency. Thus, the instrument fails to meet the criterion of an equity instrument that states that the instrument must be indexed to its own stock. On initial recognition, the warrants and the conversion feature were fair valued, with the proceeds first allocated to the freestanding warrants, then the conversion feature. The residual proceeds are then allocated to the host debt component with an effective interest rate of 27.90%. Regarding the warrant and conversion feature, the volatility input was calibrated such that the conversion feature, warrants, and host debt component, on issuance date, equates proceeds. The fair values of the freestanding warrants and conversion features were calculated to be $143 and $77, respectively, and the fair value allocated to the host debt component was $855. On July 8, 2022, the Company closed the second tranche of its non-brokered private placement of unsecured convertible debentures for gross proceeds of $925 (Note 12). The debentures bear interest at a rate of 14% per annum and mature on March 8, 2024 and are convertible into shares of the Company at $0.067 ($0.085 CAD) per share until July 8, 2023 and thereafter at $0.078 ($0.10 CAD) per share. The holder also has the option to elect at any time prior to the election date to be repaid by way of shares the Company owns of Falcon Butte (Note 5) at the rate of $0.25 per Falcon Butte share. In conjunction with the second tranche of the convertible debt financing, the Company issued 13,805,964 warrants. The warrants are exercisable into one common share of the Company at $0.067 ($0.085 CAD) per share and expire on March 8, 2024. The convertible debentures were determined to be a financial instrument comprising a host debt component, a conversion feature classified as a derivative liability, and freestanding warrants classified as a derivative liability. On initial recognition, the warrants and the conversion feature were fair valued, with the proceeds first allocated to the freestanding warrants, then the conversion feature. The residual proceeds are then allocated to the host debt component with an effective interest rate of 14%-27.46%. Regarding the warrant and conversion feature, the volatility input was calibrated such that the conversion feature, warrants, and host debt component, on issuance date, equates proceeds. The fair values of the freestanding warrants and conversion features were calculated to be $104 and $54, respectively, and the residual value allocated to the host debt component was $767. On March 2, 2023, the Company closed a third tranche of its non-brokered private placement of unsecured convertible debenture for gross proceeds of $1,306 (Note 12). The debenture bear interest at a rate of 14% per annum and mature on November 2, 2024 and are convertible into shares of the Company at $0.070 ($0.095 CAD) per share. The holder also has the option any time prior to the election date to be repaid by way of shares the Company owns of Falcon Butte (Note 5) at the rate of $0.28 ($0.37 CAD) per Falcon Butte Share.

The warrants are exercisable into one common share of the Company at $0.070 ($0.095 CAD) per share and expire on November 2, 2024. The convertible debentures were determined to be a financial instrument comprising a host debt component, a conversion feature classified as a derivative liability, and freestanding warrants classified as a derivative liability. On initial recognition, the warrants and the conversion feature were fair valued, with the proceeds first allocated to the freestanding warrants, then the conversion feature. The residual proceeds are then allocated to the host debt component with an effective interest rate of 46.07%. Regarding the warrant and conversion feature, the volatility input was calibrated such that the conversion feature, warrants, and host debt component, on issuance date, equates proceeds. The fair values of the freestanding warrants and conversion features were calculated to be $280 and $247, respectively, and the residual value allocated to the host debt component was $778. The fair value of the warrants and conversion features were determined using the Black-Scholes Option Pricing Model using the assumptions set out as follows: Initial recognition Fair value at Initial recognition Fair value at Risk-free interest rate 3.20% - 3.84 4.07% 4.27 3.78 Expected volatility 10 10 10 10 Dividend yield 0 0 0 0 Expected life 1.36 - 1.67 years 1.13 - 1.19 years 1.67 years 0.88 - 1.59 years A continuity schedule of the Company's convertible debt is as follows: Balance as at January 1, 2022 $ - Issued 2,000 Fair value of conversion Note (131 ) Fair value of Warrants (247 ) Accretion 108 Interest 144 Balance as at December 31, 2022 $ 1,874 Issued 1,306 Fair value of conversion feature (280 ) Fair value of warrants (248 ) Accretion 74 Interest 83 Balance as at March 31, 2023 $ 2,809 Current 1,996 Long-term 813

SIMPLE AGREEMENT FOR FUTURE EQUITY [Text Block]	10. SIMPLE AGREEMENT FOR FUTURE EQUITY During the year ended December 31, 2022, Blue Copper Resources Corp. raised $198 with a valuation cap of $1,450 and $569 with a valuation cap of $4,120, respectively, by entering into Simple Agreement for Future Equity Notes ("SAFE Note") with several parties. During the three months ended March 31, 2023, BCRC raised an additional $100 with a valuation cap of $4,120 by entering into SAFE notes with several parties. The private placement described above in Note 7 was considered a triggering event, and the face value of SAFE Notes of $868 were converted into common shares of BCRC resulting in 21,629,382 common shares being issued. The valuation cap provides the basis for the price at which the SAFE notes are converted into common stock of BCRC. The SAFE Notes resulted in cash proceeds to the BCRC in exchange for the right to stock of the BCRC, or cash at a future date in the occurrence of certain events, as follows: If there is an equity financing before the expiration or termination of the instrument, the BCRC will automatically issue to the investor, a number of shares of common stock equal to the purchase amount divided by the conversion price. The conversion price is equal to the price per share equal to the Valuation Cap divided by the BCRC capitalization immediately prior to the transaction. If there is a liquidity event before the expiration or termination of the instrument, the investor will, at its option, either (i) receive a cash payment equal to the purchase amount, or (ii) automatically receive from the Company a number of shares of common stock equal to the purchase amount divided by the liquidity price, if the investor fails to select the cash option. If there is a dissolution event before the instrument expires or terminates, the BCRC will pay an amount equal to the purchase amount, due and payable to the investor immediately prior to, or concurrent with, the consummation of the dissolution event. The SAFE notes were classified as liabilities pursuant to ASC 480 as certain redemptions are based upon the occurrence of certain events that are outside of the control of the Company and were measured at fair value at each reporting period, with changes in fair value recorded within the condensed interim consolidated statements of operations and comprehensive loss.

Investments, All Other Investments [Abstract]
FINANCIAL INSTRUMENT RISKS [Text Block]	17. 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, accounts payable, Rio Tinto deposit, SAFE notes, convertible debentures, derivative liability conversion feature and derivative liability warrants. Financial instruments recorded at fair value on the condensed interim 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 stockholder 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. The carrying values of cash, accounts payable, and Rio Tinto deposit approximate their fair values because of their immediate or short term to maturity and the Company's convertible debentures are recorded at amortized cost. The Company's derivative liabilities is measured at its fair value at the end of each reporting period and is categorized as Level 2 in the fair value hierarchy. 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 Condensed Interim Consolidated Statements of Operations and are categorized as Level 3 in the fair value hierarchy. a) 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) 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 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.
