Nature and Continuance of Operations and Going Concern | 1. Nature and Continuance of Operations and Going Concern Bunker Hill Mining Corp. (the “Company”) was incorporated under the laws of the state of Nevada The Company was incorporated for the purpose of engaging in mineral exploration activities. It continues to work at developing its project with a view towards putting it into production. Going Concern: These unaudited condensed interim consolidated financial statements have been prepared on a going concern basis. The Company has incurred losses since inception resulting in an accumulated deficit of $ 69,801,410 Management is considering various financing alternatives including, but not limited to, raising capital through the capital markets, debt, and closing on the multi-metals stream transaction (see note 7). These unaudited interim consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts of and classification of liabilities that might be necessary in the event the Company cannot continue in existence. The Russia/Ukraine Crisis: The Company’s operations could be adversely affected by the effects of the Russia/Ukraine crisis and the effects of sanctions imposed against Russia or that country’s retributions against those sanctions, embargos or further-reaching impacts upon energy prices, food prices and market disruptions. The Company cannot accurately predict the impact the crisis will have on its operations and the ability of contractors to meet their obligations with the Company, including uncertainties relating the severity of its effects, the duration of the conflict, and the length and magnitude of energy bans, embargos and restrictions imposed by governments. In addition, the crisis could adversely affect the economies and financial markets of the United States in general, resulting in an economic downturn that could further affect the Company’s operations and ability to finance its operations. Additionally, the Company cannot predict changes in precious metals pricing or changes in commodities pricing which may alternately affect the Company either positively or negatively. | 1. Nature and continuance of operations and going concern Nature and Continuance of Operations and Going Concern Bunker Hill Mining Corp. (the “Company”) was incorporated under the laws of the state of Nevada, U.S.A. on February 20, 2007, under the name Lincoln Mining Corp. Pursuant to a Certificate of Amendment dated February 11, 2010, the Company changed its name to Liberty Silver Corp., and on September 29, 2017, the Company changed its name to Bunker Hill Mining Corp. The Company’s registered office is located at 1802 N. Carson Street, Suite 212, Carson City, Nevada 89701, and its head office is located at 82 Richmond Street East, Toronto, Ontario, Canada, M5C 1P1. As of the date of this Form 10-Q, the Company had one subsidiary, Silver Valley Metals Corp. (“Silver Valley”, formerly American Zinc Corp.), an Idaho corporation created to facilitate the work being conducted at the Bunker Hill Mine in Kellogg, Idaho. The Company was incorporated for the initial purpose of engaging in mineral exploration activities at the Mine. The Company has moved into the development stage concurrent with (i) purchasing the Mine and a process plant, (ii) completing successive technical and economic studies, including a Prefeasibility Study, (iii) delineating mineral reserves, and (iv) conducting the program of activities outlined above. Going Concern: These consolidated financial statements have been prepared on a going concern basis. The Company has incurred losses since inception resulting in an accumulated deficit of $ 71,592,559 Management is considering various financing alternatives including, but not limited to, raising capital through the capital markets, debt, and closing on the multi-metals stream transaction (see note 8). These consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts of and classification of liabilities that might be necessary in the event the Company cannot continue in existence. COVID-19: The Company’s operations could be significantly adversely affected by the effects of a widespread global outbreak of epidemics, pandemics, or other health crises, including the recent outbreak of respiratory illness caused by the novel coronavirus (“COVID-19”). Although the pandemic has subsided significantly, the Company cannot accurately predict the impact a COVID-19 resurgence would have on its operations and the ability of others to meet their obligations with the Company, including uncertainties relating to the ultimate geographic spread of the virus, the severity of the disease, the duration of the outbreak, and the length of travel and quarantine restrictions imposed by governments of affected countries. In addition, a significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could further affect the Company’s operations and ability to finance its operations. The Russia/Ukraine Crisis: The Company’s operations could be adversely affected by the effects of the Russia/Ukraine crisis and the effects of sanctions imposed against Russia or that country’s retributions against those sanctions, embargos or further-reaching impacts upon energy prices, food prices and market disruptions. The Company cannot accurately predict the impact the crisis will have on its operations and the ability of contractors to meet their obligations with the Company, including uncertainties relating the severity of its effects, the duration of the conflict, and the length and magnitude of energy bans, embargos and restrictions imposed by governments. In addition, the crisis could adversely affect the economies and financial markets of the United States in general, resulting in an economic downturn that could further affect the Company’s operations and ability to finance its operations. Additionally, the Company cannot predict changes in precious metals pricing or changes in commodities pricing which may alternately affect the Company either positively or negatively.

Significant Accounting Policies | 2. Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed interim consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the United States Securities and Exchange Commission for interim financial information. Accordingly, they do not include all the information and footnotes necessary for a comprehensive presentation of financial position, results of operations, shareholders’ deficiency, or cash flows. It is management’s opinion, however, that all material adjustments (consisting of normal recurring adjustments) have been made which are necessary for a fair financial statement presentation. The unaudited condensed interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, which contains the annual audited consolidated financial statements and notes thereto, together with the Management’s Discussion and Analysis, for the year ended December 31, 2022. The interim results for the period ended March 31, 2023, are not necessarily indicative of the results for the full fiscal year. The unaudited interim condensed consolidated financial statements are presented in United States dollars, which is the Company’s functional currency. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes for items such as mineral reserves, useful lives and depreciation methods, potential impairment of long-lived assets, deferred income taxes, settlement pricing of commodity sales, fair value of stock based compensation, accrued liabilities, estimation of asset retirement obligations and reclamation liabilities, convertible debentures, and warrants. Estimates are based on historical experience and various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates. | 3. Significant accounting policies Significant Accounting Policies The following is a summary of significant accounting policies used in the preparation of these consolidated financial statements. Basis of consolidation These consolidated financial statements include the assets, liabilities and expenses of the Company and its wholly owned subsidiary, Silver Valley Metals Corp. (formerly American Zinc Corp.). All intercompany transactions and balances have been eliminated on consolidation. Cash and cash equivalents Cash and cash equivalents may include highly liquid investments with original maturities of three months or less. Mineral rights, property and acquisition costs The Company transitioned from the exploration stage to the development stage at the beginning of the fourth quarter of 2022. The Company has not yet realized any revenues from its planned operations. The Company capitalizes acquisition and option costs of mineral rights as intangible assets when there is sufficient evidence to support probability of generating positive economic returns in the future. Upon commencement of commercial production, the mineral rights will be amortized using the unit-of-production method over the life of the mineral rights. If the Company does not continue with exploration after the completion of the feasibility study, the mineral rights will be expensed at that time. The costs of acquiring mining properties are capitalized upon acquisition. Mine development costs incurred to develop and expand the capacity of mines, or to develop mine areas in advance of production, are also capitalized once proven and probable reserves exist and the property is a commercially mineable property. Costs incurred to maintain current exploration or to maintain assets on a standby basis are charged to operations. Costs of abandoned projects are charged to operations upon abandonment. The Company evaluates the carrying value of capitalized mining costs and related property and equipment costs, to determine if these costs are in excess of their recoverable amount whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Evaluation of the carrying value of capitalized costs and any related property and equipment costs are based upon expected future cash flows and/or estimated salvage value in accordance with Accounting Standards Codification (FASB ASC) 360-10-35, Impairment or Disposal of Long-Lived Assets. Equipment Equipment is stated at cost less accumulated depreciation. Depreciation is provided principally on the straight-line method over the estimated useful lives of the assets, which range from 3 10 The Company periodically evaluates whether events and circumstances have occurred that may warrant revision of the estimated useful lives of equipment or whether the remaining balance of the equipment should be evaluated for possible impairment. If events and circumstances warrant evaluation, the Company uses an estimate of the related undiscounted cash flows over the remaining life of the equipment in measuring their recoverability. Bunker Hill Mining Corp. Notes to Consolidated Financial Statements Years Ended December 31, 2022 and December 31, 2021 (Expressed in United States Dollars) Leases Operating lease right of use (“ROU”) assets represent the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the adoption date in determining the present value of future payments. Lease expense for minimum lease payments is amortized on a straight-line basis over the lease term and is included in operation and administration expenses in the consolidated statements of Income (loss) and comprehensive Income (loss). The Company is required to make additional payments for certain variable costs. These costs are expensed and included in operation and administration expenses in the consolidated statements of loss and comprehensive loss. Rental income obtained through subleases is recorded as income over the lease term and is offset against operation and administration expenses. Impairment of long-lived assets The Company reviews and evaluates long-lived assets for impairment when events or changes in circumstances indicate the related carrying amounts may not be recoverable. The assets are subject to impairment consideration under FASB ASC 360, Property, Plant and Equipment, if events or circumstances indicate that their carrying amount might not be recoverable. When the Company determines that an impairment analysis should be done, the analysis is performed using the rules of FASB ASC 930-360-35, Extractive Activities – Mining, and 360-10-15-3 through 15-5, Impairment or Disposal of Long-Lived Assets. Various factors could impact the Company’s ability to achieve forecasted production schedules. Additionally, commodity prices, capital expenditure requirements and reclamation costs could differ from the assumptions the Company may use in future production cash flow models when compared to factors used to assess impairment. The ability to achieve the estimated quantities of recoverable minerals from development stage mineral interests involves further risks in addition to those factors applicable to mineral interests where proven and probable reserves have been identified, due to the lower level of confidence that the identified mineralized material can ultimately be mined economically. Fair value of financial instruments The Company adopted FASB ASC 820-10, Fair Value Measurement. This guidance defines fair value, establishes a three-level valuation hierarchy for disclosures of fair value measurement and enhances disclosure requirements for fair value measures. The three levels are defined as follows: ● Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. ● Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. ● Level 3 inputs to valuation methodology are unobservable and significant to the fair measurement. The carrying amounts reported in the consolidated balance sheets for cash, restricted cash, accounts receivable excluding HST, accounts payable, accrued liabilities, interest payable, promissory notes payable, environmental protection agency water treatment payable, environmental protection agency cost recovery payable, and lease liability, all of which qualify as financial instruments, are a reasonable estimate of fair value because of the short period of time between the origination of such instruments and their expected realization and current market rate of interest. The carrying amounts of convertible loans are reported at estimated fair values as a result of the application of fair value models at each quarter end. The Company measured its DSU liability at fair value on recurring basis using level 1 inputs. Derivative warrant liabilities and convertible debentures are measured at fair value on recurring basis using level 3 inputs. Environmental expenditures The operations of the Company have been, and may in the future be, affected from time to time, in varying degrees, by changes in environmental regulations, including those for future reclamation and site restoration costs. Both the likelihood of new regulations and their overall effect upon the Company vary greatly and are not predictable. The Company’s policy is to meet, or if possible, surpass standards set by relevant legislation, by application of technically proven and economically feasible measures. Environmental expenditures that relate to ongoing environmental and reclamation programs are expensed as incurred or capitalized and amortized depending on their future economic benefits. Estimated future reclamation and site restoration costs, when the ultimate liability is reasonably determinable, are charged against earnings over the estimated remaining life of the related business operation, net of expected recoveries. Bunker Hill Mining Corp. Notes to Consolidated Financial Statements Years Ended December 31, 2022 and December 31, 2021 (Expressed in United States Dollars) Income taxes The Company accounts for income taxes in accordance with Accounting Standard Codification 740, Income Taxes (“FASB ASC 740”), on a tax jurisdictional basis. The Company files income tax returns in the United States. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax bases of assets and liabilities and the consolidated financial statements reported amounts using enacted tax rates and laws in effect in the year in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets when it is determined to be more likely than not that the deferred tax asset will not be realized. The Company assesses the likelihood of the consolidated financial statements effect of a tax position that should be recognized when it is more likely than not that the position will be sustained upon examination by a taxing authority based on the technical merits of the tax position, circumstances, and information available as of the reporting date. The Company is subject to examination by taxing authorities in jurisdictions such as the United States. Management does not believe that there are any uncertain tax positions that would result in an asset or liability for taxes being recognized in the accompanying consolidated financial statements. The Company recognizes tax-related interest and penalties, if any, as a component of income tax expense. FSAB ASC 740 prescribes recognition threshold and measurement attributes for the consolidated financial statements recognition and measurement of a tax position taken, or expected to be taken, in a tax return. FASB ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in periods, disclosure and transition. At December 31, 2022, December 31, 2021, the Company has not taken any tax positions that would require disclosure under FASB ASC 740. Basic and diluted net income (loss) per share The Company computes net income (loss) per share in accordance with FASB ASC 260, Earnings per Share (“FASB ASC 260”). Under the provisions of FASB ASC 260, basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options, RSU’s, warrants and the conversion of convertible loan payable. As of December 31, 2022, 9,005,636 162,129,064 5,470,799 9,053,136 111,412,712 3,590,907 Stock-based compensation In December 2004, FASB issued FASB ASC 718, Compensation – Stock Compensation (“FASB ASC 718”), which establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. FASB ASC 718 focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions. FASB ASC 718 requires that the compensation cost relating to share-based payment transactions be recognized in the consolidated financial statements. That cost will be measured based on the fair value of the equity or liability instruments issued. The Company accounts for stock-based compensation arrangements with non-employees in accordance with ASU 505-50, Equity-Based Payments to Non-Employees, which requires that such equity instruments are recorded at the value on the grant date based on fair value of the equity or goods and services whichever is more reliable. Restricted share units (“RSUs”) The Company estimates the grant date fair value of RSUs using the Company’s common shares at the grant date. The Company records the value of the RSUs in paid-in capital. Deferred share units (“DSUs”) The Company estimates the grant date fair value of the DSUs using the trading price of the Company’s common shares on the day of grant. The Company records the value of the DSUs owing to its directors as DSU liability and measures the DSU liability at fair value at each reporting date, with changes in fair value recognized as stock-based compensation in profit (loss). Bunker Hill Mining Corp. Notes to Consolidated Financial Statements Years Ended December 31, 2022 and December 31, 2021 (Expressed in United States Dollars) Use of estimates and assumptions Use of Estimates Many of the amounts included in the consolidated financial statements require management to make judgments and/or estimates. These judgments and estimates are continuously evaluated and are based on management’s experience and knowledge of the relevant facts and circumstances. Actual results may differ from the amounts included in the consolidated financial statements. Areas of significant judgment and estimates affecting the amounts recognized in the consolidated financial statements include: Going concern The assessment of the Company’s ability to continue as a going concern involves judgment regarding future funding available for its operations and working capital requirements as discussed in note 1. Accrued liabilities The Company has to make estimates to accrue for certain expenditures due to delay in receipt of third-party vendor invoices. These accruals are made based on trends, history and knowledge of activities. Actual results may be different. The Company makes monthly estimates of its water treatment costs, with a true-up to the annual invoice received from the Idaho Department of Environmental Quality (“IDEQ”). Using the actual costs in the annual invoice, the Company then reassesses its estimate for future periods. Given the nature, complexity and variability of the various actual cost items included in the invoice, the Company has used the most recent invoice as its estimate of the water treatment costs for future periods. Convertible loans, promissory notes and warrants Estimating the fair value of derivative warrant liability requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the issuance. This estimate also requires determining the most appropriate inputs to the valuation model including the expected life of the warrants derivative liability, volatility and dividend yield and making assumptions about them. The assumptions and models used for estimating fair value of warrants derivative liability are disclosed in Notes 9 and 11. The fair value estimates of the convertible loans use inputs to the valuation model that include risk-free rates, equity value per common share, USD-CAD exchange rates, spot and futures prices of minerals, expected equity volatility, expected volatility in minerals prices, discount for lack of marketability, credit spread, expected mineral production over the life of the mine, and project risk/estimation risk factors. See Note 11 for full disclosures related to the convertible loans and promissory notes. The fair value estimates may differ from actual fair values and these differences may be significant and could have a material impact on the Company’s balance sheets and the consolidated statements of operations. Assets are reviewed for an indication of impairment at each reporting date. This determination requires significant judgment. Factors that could trigger an impairment review include, but are not limited to, significant negative industry or economic trends, interruptions in exploration activities or a significant drop in precious metal prices. Reclassifications Certain reclassifications have been made to conform prior year’s data to the current presentation. The reclassifications have no effect on the results of reported operations or stockholders’ deficit or cash flows. Concentrations of credit risk The Company’s financial instruments that are exposed to concentrations of credit risk primarily consist of its cash and restricted cash. The Company places its cash with financial institutions of high credit worthiness. At times, its cash equivalents with a particular financial institution may exceed any applicable government insurance limits. The Company’s management also routinely assesses the financial strength and credit worthiness of any parties to which it extends funds and as such, it believes that any associated credit risk exposures are limited. Risks and uncertainties The Company operates in the mineral resource exploration and mine development industry that is subject to significant risks and uncertainties, including financial, operational, and other risks associated with operating a mineral resource exploration business, including the potential risk of business failure. Bunker Hill Mining Corp. Notes to Consolidated Financial Statements Years Ended December 31, 2022 and December 31, 2021 (Expressed in United States Dollars) Foreign currency transactions The Company from time to time will receive invoices from service providers that are presenting their invoices using the Canadian dollar. The Company will use its U.S. dollars to settle the Canadian dollar liabilities and any differences resulting from the exchange transaction are reported as gain or loss on foreign exchange. Convertible loans and promissory notes payable The Company reviews the terms of its convertible loans and promissory notes payable to determine whether there are embedded derivatives, including the embedded options, that are required to be bifurcated and accounted for as individual derivative financial instruments. In circumstances where the convertible loans or the promissory note contains embedded derivatives that are to be separated from the host contracts, the total proceeds received are first allocated to the fair value of the derivative financial instruments determined using the binomial model. The remaining proceeds, if any, are then allocated to the debenture cost contracts, usually resulting in those instruments being recorded at a discount from their principal amount. This discount is accreted over the expected life of the instruments to profit (loss) using the effective interest method. In circumstances where the convertible loans or the promissory note contains embedded derivatives that are not separated from the host contracts, the fair values of the host contract and the derivative are valued together, with the change in fair value accounted through earnings, profit and loss for each period reported. The debenture host contracts are subsequently recorded at amortized cost at each reporting date, using the effective interest method. The embedded derivatives are subsequently recorded at fair value at each reporting date, with changes in fair value recognized in profit (loss). The Company applies ASC 480 distinguishing liabilities from equity and ASC 815 derivatives and hedging in determining the appropriate accounting treatment for hybrid instruments. The embedded options within the convertible loans are not bifurcated and measured at fair value at each period end. Recent Accounting Pronouncements Accounting Standards Updates Adopted In August 2020, No. 2020 06 470 20 815 40 Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

The package comprises substantially all processing equipment of value located at the Pend Oreille mine site, including complete crushing, grinding and flotation circuits suitable for a planned ~1,500 ton-per-day operation at the Bunker Hill site, and total inventory of nearly 10,000 components and parts for mill, assay lab, conveyer, field instruments, and electrical spares. The purchase of the mill has been valued at: - Cash consideration given, comprised of $ 500,000 231,000 731,000 - Value of common shares issued on May 13, 2022 at the market price of that day, a value of $ 1,970,264 - Fair value of the warrants issued together with the inputs, as determined by a binomial model, resulted in a fair value of $ 1,273,032 - As a result, the total value of the mill at the time of purchase was determined to be $ 3,974,296 341,004 The process plant was purchased in an assembled state in the seller’s location, and included major processing systems, significant components, and a large inventory of spare parts. The Company has disassembled and transported it to the Bunker Hill site, and will be reassembling it as an integral part of the Company’s future operations. The Company determined that the transaction should be accounted for as an asset acquisition, with the process plant representing a single asset, with the exception of the inventory of spare parts, which has been separated out and appears on the balance sheets as a non-current asset in accordance with a preliminary purchase price allocation. As the plant is demobilized, transported and reassembled, installation and other costs associated with these activities will be captured and capitalized as components of the asset.

Commitments and Contingencies | 12. Commitments and Contingencies As stipulated in the agreement with the EPA and as described in Note 6, the Company is required to make two types of payments to the EPA and IDEQ, one for historical water treatment cost-recovery to the EPA, and the other for ongoing water treatment. Water treatment costs incurred through December 2021 are payable to the EPA, and water treatment costs incurred thereafter are payable to the IDEQ. The IDEQ (as done formerly by the EPA) invoices the Company on an annual basis for the actual water treatment costs, which may exceed the recognized estimated costs significantly. When the Company receives the water treatment invoices, it records any liability for actual costs over and above any estimates made and adjusts future estimates as required based on these actual invoices received. The Company is required to pay for the actual costs regardless of the periodic required estimated accruals and payments made each year. On July 28, 2021, a lawsuit was filed in the US District Court for the District of Idaho brought by Crescent Mining, LLC (“Crescent”). The named defendants include Placer Mining, Robert Hopper Jr., and the Company. The lawsuit alleges that Placer Mining and Robert Hopper Jr. intentionally flooded the Crescent Mine during the period from 1991 and 1994, and that the Company is jointly and severally liable with the other defendants for unspecified past and future costs associated with the presence of AMD in the Crescent Mine. The plaintiff has requested unspecified damages. On September 20, 2021, the Company filed a motion to dismiss Crescent’s claims against it, contending that such claims are facially deficient. On March 2, 2022, Chief US District Court Judge, David C. Nye granted in part and denied in part the Company’s motion to dismiss. The court granted the Company’s motion to dismiss Crescent’s Cost Recovery claim under CERCLA Section 107(a), Declaratory Judgment, Tortious Interference, Trespass, Nuisance and Negligence claims. These claims were dismissed without prejudice. The court denied the motion to dismiss filed by Placer Mining Corp. for Crescent’s trespass, nuisance and negligence claims. Crescent later filed an amended complaint on April 1, 2022. Placer Mining Corp. and Bunker Hill Mining Corp are named as co-defendants. Bunker Hill responded to the amended filing, refuting and denying all allegations made in the complaint except those that are assertions of fact as a matter of public record. The Company believes Crescent’s lawsuit is without merit and intends to vigorously defend itself, as well as Placer Mining Corp. pursuant to the Company’s indemnification of Placer Mining Corp in the Sale and Purchase agreement executed between the companies for the Mine on December 15, 2021. During the three months ended March 31, 2023, the Company entered into a lease agreement with C & E Tree Farm LLC for the lease of a land parcel overlaying a portion of the Company’s existing mineral claims package.

Significant Accounting Policies (Policies) | 3 Months Ended | 12 Months Ended |
Mar. 31, 2023 | Dec. 31, 2022 | |
Accounting Policies [Abstract] | ||
Basis of consolidation | Basis of consolidation These consolidated financial statements include the assets, liabilities and expenses of the Company and its wholly owned subsidiary, Silver Valley Metals Corp. (formerly American Zinc Corp.). All intercompany transactions and balances have been eliminated on consolidation. | |
Cash and cash equivalents | Cash and cash equivalents Cash and cash equivalents may include highly liquid investments with original maturities of three months or less. | |
Mineral rights, property and acquisition costs | Mineral rights, property and acquisition costs The Company transitioned from the exploration stage to the development stage at the beginning of the fourth quarter of 2022. The Company has not yet realized any revenues from its planned operations. The Company capitalizes acquisition and option costs of mineral rights as intangible assets when there is sufficient evidence to support probability of generating positive economic returns in the future. Upon commencement of commercial production, the mineral rights will be amortized using the unit-of-production method over the life of the mineral rights. If the Company does not continue with exploration after the completion of the feasibility study, the mineral rights will be expensed at that time. The costs of acquiring mining properties are capitalized upon acquisition. Mine development costs incurred to develop and expand the capacity of mines, or to develop mine areas in advance of production, are also capitalized once proven and probable reserves exist and the property is a commercially mineable property. Costs incurred to maintain current exploration or to maintain assets on a standby basis are charged to operations. Costs of abandoned projects are charged to operations upon abandonment. The Company evaluates the carrying value of capitalized mining costs and related property and equipment costs, to determine if these costs are in excess of their recoverable amount whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Evaluation of the carrying value of capitalized costs and any related property and equipment costs are based upon expected future cash flows and/or estimated salvage value in accordance with Accounting Standards Codification (FASB ASC) 360-10-35, Impairment or Disposal of Long-Lived Assets. | |
Equipment | Equipment Equipment is stated at cost less accumulated depreciation. Depreciation is provided principally on the straight-line method over the estimated useful lives of the assets, which range from 3 10 The Company periodically evaluates whether events and circumstances have occurred that may warrant revision of the estimated useful lives of equipment or whether the remaining balance of the equipment should be evaluated for possible impairment. If events and circumstances warrant evaluation, the Company uses an estimate of the related undiscounted cash flows over the remaining life of the equipment in measuring their recoverability.

Leases | Leases Operating lease right of use (“ROU”) assets represent the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the adoption date in determining the present value of future payments. Lease expense for minimum lease payments is amortized on a straight-line basis over the lease term and is included in operation and administration expenses in the consolidated statements of Income (loss) and comprehensive Income (loss). The Company is required to make additional payments for certain variable costs. These costs are expensed and included in operation and administration expenses in the consolidated statements of loss and comprehensive loss. Rental income obtained through subleases is recorded as income over the lease term and is offset against operation and administration expenses. | |
Impairment of long-lived assets | Impairment of long-lived assets The Company reviews and evaluates long-lived assets for impairment when events or changes in circumstances indicate the related carrying amounts may not be recoverable. The assets are subject to impairment consideration under FASB ASC 360, Property, Plant and Equipment, if events or circumstances indicate that their carrying amount might not be recoverable. When the Company determines that an impairment analysis should be done, the analysis is performed using the rules of FASB ASC 930-360-35, Extractive Activities – Mining, and 360-10-15-3 through 15-5, Impairment or Disposal of Long-Lived Assets. Various factors could impact the Company’s ability to achieve forecasted production schedules. Additionally, commodity prices, capital expenditure requirements and reclamation costs could differ from the assumptions the Company may use in future production cash flow models when compared to factors used to assess impairment. The ability to achieve the estimated quantities of recoverable minerals from development stage mineral interests involves further risks in addition to those factors applicable to mineral interests where proven and probable reserves have been identified, due to the lower level of confidence that the identified mineralized material can ultimately be mined economically. | |
Fair value of financial instruments | Fair value of financial instruments The Company adopted FASB ASC 820-10, Fair Value Measurement. This guidance defines fair value, establishes a three-level valuation hierarchy for disclosures of fair value measurement and enhances disclosure requirements for fair value measures. The three levels are defined as follows: ● Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. ● Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. ● Level 3 inputs to valuation methodology are unobservable and significant to the fair measurement. The carrying amounts reported in the consolidated balance sheets for cash, restricted cash, accounts receivable excluding HST, accounts payable, accrued liabilities, interest payable, promissory notes payable, environmental protection agency water treatment payable, environmental protection agency cost recovery payable, and lease liability, all of which qualify as financial instruments, are a reasonable estimate of fair value because of the short period of time between the origination of such instruments and their expected realization and current market rate of interest. The carrying amounts of convertible loans are reported at estimated fair values as a result of the application of fair value models at each quarter end. The Company measured its DSU liability at fair value on recurring basis using level 1 inputs. Derivative warrant liabilities and convertible debentures are measured at fair value on recurring basis using level 3 inputs. | |
Environmental expenditures | Environmental expenditures The operations of the Company have been, and may in the future be, affected from time to time, in varying degrees, by changes in environmental regulations, including those for future reclamation and site restoration costs. Both the likelihood of new regulations and their overall effect upon the Company vary greatly and are not predictable. The Company’s policy is to meet, or if possible, surpass standards set by relevant legislation, by application of technically proven and economically feasible measures. Environmental expenditures that relate to ongoing environmental and reclamation programs are expensed as incurred or capitalized and amortized depending on their future economic benefits. Estimated future reclamation and site restoration costs, when the ultimate liability is reasonably determinable, are charged against earnings over the estimated remaining life of the related business operation, net of expected recoveries.

Income taxes | Income taxes The Company accounts for income taxes in accordance with Accounting Standard Codification 740, Income Taxes (“FASB ASC 740”), on a tax jurisdictional basis. The Company files income tax returns in the United States. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax bases of assets and liabilities and the consolidated financial statements reported amounts using enacted tax rates and laws in effect in the year in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets when it is determined to be more likely than not that the deferred tax asset will not be realized. The Company assesses the likelihood of the consolidated financial statements effect of a tax position that should be recognized when it is more likely than not that the position will be sustained upon examination by a taxing authority based on the technical merits of the tax position, circumstances, and information available as of the reporting date. The Company is subject to examination by taxing authorities in jurisdictions such as the United States. Management does not believe that there are any uncertain tax positions that would result in an asset or liability for taxes being recognized in the accompanying consolidated financial statements. The Company recognizes tax-related interest and penalties, if any, as a component of income tax expense. FSAB ASC 740 prescribes recognition threshold and measurement attributes for the consolidated financial statements recognition and measurement of a tax position taken, or expected to be taken, in a tax return. FASB ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in periods, disclosure and transition. At December 31, 2022, December 31, 2021, the Company has not taken any tax positions that would require disclosure under FASB ASC 740. | |
Basic and diluted net income (loss) per share | Basic and diluted net income (loss) per share The Company computes net income (loss) per share in accordance with FASB ASC 260, Earnings per Share (“FASB ASC 260”). Under the provisions of FASB ASC 260, basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options, RSU’s, warrants and the conversion of convertible loan payable. As of December 31, 2022, 9,005,636 162,129,064 5,470,799 9,053,136 111,412,712 3,590,907 | |
Stock-based compensation | Stock-based compensation In December 2004, FASB issued FASB ASC 718, Compensation – Stock Compensation (“FASB ASC 718”), which establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. FASB ASC 718 focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions. FASB ASC 718 requires that the compensation cost relating to share-based payment transactions be recognized in the consolidated financial statements. That cost will be measured based on the fair value of the equity or liability instruments issued. The Company accounts for stock-based compensation arrangements with non-employees in accordance with ASU 505-50, Equity-Based Payments to Non-Employees, which requires that such equity instruments are recorded at the value on the grant date based on fair value of the equity or goods and services whichever is more reliable. | |
Restricted share units (“RSUs”) | Restricted share units (“RSUs”) The Company estimates the grant date fair value of RSUs using the Company’s common shares at the grant date. The Company records the value of the RSUs in paid-in capital. | |
Deferred share units (“DSUs”) | Deferred share units (“DSUs”) The Company estimates the grant date fair value of the DSUs using the trading price of the Company’s common shares on the day of grant. The Company records the value of the DSUs owing to its directors as DSU liability and measures the DSU liability at fair value at each reporting date, with changes in fair value recognized as stock-based compensation in profit (loss).

Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes for items such as mineral reserves, useful lives and depreciation methods, potential impairment of long-lived assets, deferred income taxes, settlement pricing of commodity sales, fair value of stock based compensation, accrued liabilities, estimation of asset retirement obligations and reclamation liabilities, convertible debentures, and warrants. Estimates are based on historical experience and various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates. | Use of estimates and assumptions Use of Estimates Many of the amounts included in the consolidated financial statements require management to make judgments and/or estimates. These judgments and estimates are continuously evaluated and are based on management’s experience and knowledge of the relevant facts and circumstances. Actual results may differ from the amounts included in the consolidated financial statements. Areas of significant judgment and estimates affecting the amounts recognized in the consolidated financial statements include: Going concern The assessment of the Company’s ability to continue as a going concern involves judgment regarding future funding available for its operations and working capital requirements as discussed in note 1. Accrued liabilities The Company has to make estimates to accrue for certain expenditures due to delay in receipt of third-party vendor invoices. These accruals are made based on trends, history and knowledge of activities. Actual results may be different. The Company makes monthly estimates of its water treatment costs, with a true-up to the annual invoice received from the Idaho Department of Environmental Quality (“IDEQ”). Using the actual costs in the annual invoice, the Company then reassesses its estimate for future periods. Given the nature, complexity and variability of the various actual cost items included in the invoice, the Company has used the most recent invoice as its estimate of the water treatment costs for future periods. Convertible loans, promissory notes and warrants Estimating the fair value of derivative warrant liability requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the issuance. This estimate also requires determining the most appropriate inputs to the valuation model including the expected life of the warrants derivative liability, volatility and dividend yield and making assumptions about them. The assumptions and models used for estimating fair value of warrants derivative liability are disclosed in Notes 9 and 11. The fair value estimates of the convertible loans use inputs to the valuation model that include risk-free rates, equity value per common share, USD-CAD exchange rates, spot and futures prices of minerals, expected equity volatility, expected volatility in minerals prices, discount for lack of marketability, credit spread, expected mineral production over the life of the mine, and project risk/estimation risk factors. See Note 11 for full disclosures related to the convertible loans and promissory notes. The fair value estimates may differ from actual fair values and these differences may be significant and could have a material impact on the Company’s balance sheets and the consolidated statements of operations. Assets are reviewed for an indication of impairment at each reporting date. This determination requires significant judgment. Factors that could trigger an impairment review include, but are not limited to, significant negative industry or economic trends, interruptions in exploration activities or a significant drop in precious metal prices. |
Reclassifications | Reclassifications Certain reclassifications have been made to conform prior year’s data to the current presentation. The reclassifications have no effect on the results of reported operations or stockholders’ deficit or cash flows. | |
Concentrations of credit risk | Concentrations of credit risk The Company’s financial instruments that are exposed to concentrations of credit risk primarily consist of its cash and restricted cash. The Company places its cash with financial institutions of high credit worthiness. At times, its cash equivalents with a particular financial institution may exceed any applicable government insurance limits. The Company’s management also routinely assesses the financial strength and credit worthiness of any parties to which it extends funds and as such, it believes that any associated credit risk exposures are limited. | |
Risks and uncertainties | Risks and uncertainties The Company operates in the mineral resource exploration and mine development industry that is subject to significant risks and uncertainties, including financial, operational, and other risks associated with operating a mineral resource exploration business, including the potential risk of business failure. | |
Foreign currency transactions | Foreign currency transactions The Company from time to time will receive invoices from service providers that are presenting their invoices using the Canadian dollar. The Company will use its U.S. dollars to settle the Canadian dollar liabilities and any differences resulting from the exchange transaction are reported as gain or loss on foreign exchange. | |
Convertible loans and promissory notes payable | Convertible loans and promissory notes payable The Company reviews the terms of its convertible loans and promissory notes payable to determine whether there are embedded derivatives, including the embedded options, that are required to be bifurcated and accounted for as individual derivative financial instruments. In circumstances where the convertible loans or the promissory note contains embedded derivatives that are to be separated from the host contracts, the total proceeds received are first allocated to the fair value of the derivative financial instruments determined using the binomial model. The remaining proceeds, if any, are then allocated to the debenture cost contracts, usually resulting in those instruments being recorded at a discount from their principal amount. This discount is accreted over the expected life of the instruments to profit (loss) using the effective interest method. In circumstances where the convertible loans or the promissory note contains embedded derivatives that are not separated from the host contracts, the fair values of the host contract and the derivative are valued together, with the change in fair value accounted through earnings, profit and loss for each period reported. The debenture host contracts are subsequently recorded at amortized cost at each reporting date, using the effective interest method. The embedded derivatives are subsequently recorded at fair value at each reporting date, with changes in fair value recognized in profit (loss). The Company applies ASC 480 distinguishing liabilities from equity and ASC 815 derivatives and hedging in determining the appropriate accounting treatment for hybrid instruments. The embedded options within the convertible loans are not bifurcated and measured at fair value at each period end. | |
Recent Accounting Pronouncements | Recent Accounting Pronouncements Accounting Standards Updates Adopted In August 2020, No. 2020 06 470 20 815 40 Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements. | |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed interim consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the United States Securities and Exchange Commission for interim financial information. Accordingly, they do not include all the information and footnotes necessary for a comprehensive presentation of financial position, results of operations, shareholders’ deficiency, or cash flows. It is management’s opinion, however, that all material adjustments (consisting of normal recurring adjustments) have been made which are necessary for a fair financial statement presentation. The unaudited condensed interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, which contains the annual audited consolidated financial statements and notes thereto, together with the Management’s Discussion and Analysis, for the year ended December 31, 2022. The interim results for the period ended March 31, 2023, are not necessarily indicative of the results for the full fiscal year. The unaudited interim condensed consolidated financial statements are presented in United States dollars, which is the Company’s functional currency. |

Thereafter, the Stream would apply to 2% of payable metals sold. If the Company elects to draw less than $37,000,000 under the Stream, the percentage and quantities of payable metals streamed will adjust pro-rata. The delivery price of streamed metals will be 20% of the applicable spot price. The Company may buy back 50% of the Stream Amount at a 1.40x multiple of the Stream Amount between the second and third anniversary of the date of funding, and at a 1.65x multiple of the Stream Amount between the third and fourth anniversary of the date of funding.
