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 $ 75,372,036 and further losses are anticipated in the development of its business. Additionally, the Company owes a total of $ 17,497,236 to the Environmental Protection Agency (“EPA”) (see Note 6) that is classified as current liability unless the Company can consummate financial assurances that would reclassify $ 12,000,000 of this liability to long-term debt. The Company owes a total of $ 3,540,852 , net of discount, to the EPA that is classified as long-term debt. The Company does not have sufficient cash to fund normal operations and meet debt obligations for the next 12 months without deferring payment on certain current liabilities and/or raising additional funds. In order to continue to meet its fiscal obligations in the current fiscal year and beyond, the Company must seek additional financing. This raises substantial doubt about the Company’s ability to continue as a going concern. Its ability to continue as a going concern is dependent upon the ability of the Company to generate profitable operations in the future and/or to obtain the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. The accompanying condensed interim consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Management is considering various financing alternatives including, but not limited to, raising capital through the capital markets and debt financing. 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. The ability of the Company to emerge from the exploration stage is dependent upon, among other things, obtain additional financing to continue operations, explore and develop the mineral properties and the discovery, development, and sale of reserves. 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”). The Company cannot accurately predict the impact COVID-19 will 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 escalating 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. | Nature and continuance of operations and going concern Nature and Continuance of Operations and Going Concern Bunker Hill Mining Corp.

Significant accounting policies | 3. 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 has been in the exploration stage since its formation on February 20, 2007 and has not yet realized any revenues from its planned operations. It is primarily engaged in the acquisition and exploration of mining properties. 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. 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 loss and comprehensive 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 cash flow models used to assess impairment. The ability to achieve the estimated quantities of recoverable minerals from exploration 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, accounts receivable excluding HST, accounts payable, accrued liabilities, interest payable, convertible loan payable, promissory notes payable, lease liability, and other liabilities, 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 Company measured its DSU liability at fair value on recurring basis using level 1 inputs and derivative warrant liabilities 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. 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, 2021, December 31, 2020, and June 30, 2020, the Company has not taken any tax positions that would require disclosure under FASB ASC 740. Basic and diluted net loss per share The Company computes net loss per share in accordance with FASB ASC 260, Earnings per Share (“FASB ASC 260”). Under the provisions of FASB ASC 260, basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net 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 and warrants and the conversion of convertible loan payable. As of December 31, 2021, 9,053,136 111,412,712 3,590,907 8,015,159 95,777,806 3,239,907 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). Use of estimates and assumptions 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 and conversion feature derivative 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 and conversion feature derivative liability, volatility and dividend yield and making assumptions about them. The assumptions and models used for estimating fair value of warrants and conversion feature derivative liability are disclosed in notes 8 and 10. 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. 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 mineralized material exploration industry that is subject to significant risks and uncertainties, including financial, operational, and other risks associated with operating a mineralized material exploration business, including the potential risk of business failure. 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 conversion option, that are required to be bifurcated and accounted for as individual derivative financial instruments. In circumstances where the convertible debt 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. 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 presents its embedded derivatives and related debenture host contracts as separate instruments on the consolidated balance sheets. |

Mining Interests Bunker Hill Mine Complex On November 27, 2016, the Company entered into a non-binding letter of intent with Placer Mining Corp. (“Placer Mining”), which letter of intent was further amended on March 29, 2017, to acquire the Bunker Hill Mine in Idaho and its associated milling facility located in Kellogg, Idaho, in the Coeur d’Alene Basin (as amended, the “Letter of Intent”). Pursuant to the terms and conditions of the Letter of Intent, the acquisition, which was subject to due diligence, would include all mining claims, surface rights, fee parcels, mineral interests, existing infrastructure, machinery and buildings at the Kellogg Tunnel portal in Milo Gulch, or anywhere underground at the Bunker Hill Mine Complex. The acquisition would also include all current and historic data relating to the Bunker Hill Mine Complex, such as drill logs, reports, maps, and similar information located at the mine site or any other location. During the year ended June 30, 2017, the Company made payments totaling $ 300,000 On August 28, 2017, the Company announced that it signed a definitive agreement (the “Agreement”) for the lease and option to purchase the Bunker Hill Mine assets (the “Bunker Assets”). Under the terms of the Agreement, the Company was required to make a $ 1,000,000 500,000 100,000 The Company had an option to purchase the Bunker Assets at any time before the end of the lease and any extension for a purchase price of $ 45,000,000 3 1.5 60,000,000 On October 2, 2018, the Company announced that it was in default of the Agreement. The default arose as a result of missed lease and operating cost payments, totaling $ 400,000 On November 13, 2018, the Company announced that it was successful in renewing the Agreement, effectively with the original Agreement intact, except monthly payments were reduced to $ 60,000 per month for 12 months, with the accumulated reduction in payments of $ 140,000 per month (“deferred payments”) being accrued. On November 1, 2019, the Agreement was amended (the “Amended Agreement”). The key terms of the Amended Agreement are as follows: ● The lease period was extended for an additional period of nine months to August 1, 2020, with the option to extend for a further six months based upon payment of a one-time $ 60,000 ● The Company will make monthly care and maintenance payments to Placer Mining of $ 60,000 ● The purchase price is set at $ 11,000,000 100 6,200,000 4,800,000 20,000,000 300,000 On July 27, 2020, the Company extended the lease with Placer Mining for a further 18 months for a $ 150,000 On November 20, 2020, the Company signed a further amendment to the Amended Agreement. Under the terms of this amendment: ● The Company will continue to make monthly care and maintenance payments to Placer Mining of $ 60,000 ● The purchase price was reduced to $ 7,700,000 5,700,000 300,000 5,400,000 2,000,000 ● The Company’s contingent obligation to settle $ 1,787,300 1,787,300 ● The Company is to make an advance payment of $ 2,000,000 2,000,000 3,400,000 2,000,000 As at December 31, 2021 and 2020, the Company accrued for a total of $nil for each year (June 30, 2020 - $ 1,847,300 Purchase of the Bunker Hill Mine: In December 2021, the Company announced its intention to purchase the mine complex, which was consummated subsequent to the close of the period. With the execution of the EPA settlement agreement amendment described below and the expected receipt of $ 8,000,000 proceeds from the Royalty Convertible Debenture, the Company has contracted to purchase the Bunker Hill Mine from Placer Mining Corp. and a definitive agreement has been signed by both parties. The terms of the purchase were modified to a purchase price of $ 7,700,000 300,000 2,000,000 5,400,000 in cash, from $ 3,400,000 of cash and $ 2,000,000 of common shares in the Company. Purchase of the mine consists of over 400 patented mining claims and 5,800 acres of private land. Closing of the transaction occurred in January 2022, concurrent with funding of the Royalty Convertible Debenture, approval of the transaction by Placer Mining Corp. shareholders, and satisfaction of other closing conditions. See Note 16, Subsequent Events. Environmental Protection Agency Agreement: In addition to the payments to Placer Mining described above, and pursuant to an agreement with the EPA whereby for so long as Bunker leases, owns and/or occupies the Bunker Hill Mine, the Company will make payments to the EPA on behalf of the current owner in satisfaction of the EPA’s claim for cost recovery. These payments, if all are made, will total $ 20,000,000 1,000,000 Schedule of Payments for Mining Date Amount Action Within 30 days of the effective date $ 1,000,000 Paid November 1, 2018 $ 2,000,000 Not paid November 1, 2019 $ 3,000,000 Not paid November 1, 2020 $ 3,000,000 Not paid November 1, 2021 $ 3,000,000 Not paid November 1, 2022 $ 3,000,000 November 1, 2023 $ 3,000,000 November 1, 2024 $ 2,000,000 The total unpaid EPA cost recovery payments under the agreement was $ 11,000,000 8,000,000 5,000,000 In addition to these cost recovery payments, the Company is to make semi-annual payments of $ 480,000 on June 1 and December 1 of each year, to cover the EPA’s costs of operating and maintaining the water treatment facility that treats the water being discharged from the Bunker Hill Mine. The Company also has received invoices from the EPA for additional water treatment charges for the periods from December 2017 to May 2021, and has accrued costs for estimated water treatment costs through December 31, 2021. A total of $ 5,110,706 was outstanding as at December 31, 2021 (December 31, 2020 - $ 3,136,050 and June 30, 2020 - $ 2,309,388 , respectively). In December 2021, the Company entered into a Settlement Amendment, described below, under which a payment of $ 2,963,111 would be made toward water treatment liabilities, representing the balance of liabilities owed for the 2020 and earlier invoices, net of payments made through the end of September 2021. In consultation with the EPA, the Company has committed to meet this obligation by 180 days from the effective date of the Amended Settlement Agreement. The unpaid EPA balance is subject to interest at the rate specified for interest on investments of the EPA Hazardous Substance Superfund, which was 0.10 % at December 31, 2021. As at December 31, 2021, the interest accrued on the unpaid EPA balance was $ 306,502 (December 31, 2020 - $ 162,540 and June 30, 2020 - $ 89,180 , respectively). During the year ended December 31, 2021, the Company has accrued an estimate for additional water treatment charges based on an invoice received covering the period of November 2019 to October 2020 and a further invoice covering the period of November 2020 to May 2021. The Company believes that the charges in this latter invoice, of approximately $ 165,000 per month, represent the best estimate of unbilled charges for the period of June 2021 to December 2021, and has accrued for these charges accordingly. Net of a total of $ 880,000 cash payments made to the EPA during the year, the total accrual for EPA water treatment charges is $ 5,110,706 as of December 31, 2021, before consideration of unpaid cost recovery payments. The Company has included all unpaid and accrued EPA payments and accrued interest in accounts payable and accrued liabilities, totaling $ 16,417,208 due to the EPA at December 31, 2021 (December 31, 2020 - $ 11,298,594 and June 30, 2020 - $ 7,915,235 , respectively). For the year ended December 31, 2021, water treatment costs of $ 5,998,615 3,873,359 5,905,235 EPA Settlement Agreement Amendment: In December 2021, in conjunction with its intention to purchase the mine complex, the Company entered into an amended Settlement Agreement (the “Amendment”) between the Company, Idaho Department of Environmental Quality, US Department of Justice and the EPA, modifying the payment schedule and payment terms for recovery of historical environmental response costs at Bunker Hill Mine incurred by the EPA. With the purchase of the mine subsequent to the end of the period, the remaining payments of the EPA cost recovery liability would be assumed by the Company, resulting in a total of $ 19,000,000 liability to the Company, an increase of $ 8,000,000 . The new payment schedule includes a $ 2,000,000 payment to the EPA within 30 days of execution of this amendment, which was paid subsequent to December 31, 2021. The remaining $ 17,000,000 will be paid on the following dates: Schedule of Payments for Mining Date Amount November 1, 2024 $ 3,000,000 November 1, 2025 $ 3,000,000 November 1, 2026 $ 3,000,000 November 1, 2027 $ 3,000,000 November 1, 2028 $ 3,000,000 November 1, 2029 $ 2,000,000 The resumption of payments in 2024 were agreed in order to allow the Company to generate sufficient revenue from mining activities at the Bunker Hill Mine to address remaining payment obligations from free cash flow. In addition to the cost recovery payments outlined above, the Amendment includes payment for outstanding water treatment costs that have been incurred over the period from 2018 through October 2020. This approximately $ 2,900,000 payment would be made within 90 days of the execution of the Amendment. On March 22, 2022, the Company reported that in consultation with the EPA, it has committed to meet the approximately $ 2,900,000 The changes in payment terms and schedule, are contingent upon the Company securing Financial Assurance in the form of performance bonds or letters of credit deemed acceptable to the EPA totaling $ 17,000,000 As at December 31, 2021, the Company had not secured the interim financial assurance, and therefore the contingency had not been removed or satisfied. Further, as of the date of this filing, the financial assurance has not been secured, and as a result, the liability to the EPA is accounted for with no effectivity of the Amendment, with the liabilities each reflected as current liabilities.

Convertible loan payable On June 13, 2018, the Company entered into a loan and warrant agreement with Hummingbird Resources PLC (“Hummingbird”), an arm’s length investor, for an unsecured convertible loan in the aggregate sum of $ 1,500,000 10 one year 229,464 229,464 8.50 two years In the event that a notice of conversion would result in the lender holding 10% or more of the Company’s issued and outstanding shares, then, in the alternative, and under certain circumstances, the Company would be required to pay cash to the lender in an amount equal to C$ 8.50 In August 2018, the amount of the Hummingbird convertible loan payable was increased to $ 2,000,000 1,500,000 45,824 116,714 4.50 1,500,000 8.50 229,464 8.50 500,000 4.50 116,714 4.50 During the year ended June 30, 2019, Hummingbird agreed to extend the scheduled maturity date of the loan to June 30, 2020 1,195,880 In June 2019, the Company settled $ 100,000 2,660,000 8,193 In February 2020, the Company settled $ 300,000 696,428 9,407 In June 2020, Hummingbird agreed to extend the scheduled maturity date of the loan to July 31, 2020 In October 2020, the Company settled the full amount of the outstanding loan by issuing 5,572,980 0.49 23,376 The Company has accounted for the conversion features and warrants in accordance with ASC Topic 815. The conversion features and warrants are considered derivative financial liabilities as they are convertible into common shares at a conversion price denominated in a currency other than the Company’s functional currency of the U.S. dollar. The estimated fair value of the conversion features and warrants was determined on the date of issuance and marks to market at each financial reporting period. As at December 31, 2020, the fair values of the conversion feature and warrants were $nil (June 30, 2020 - $nil).

Promissory Note Payable and Convertible Debentures | 7. Promissory Note Payable and Convertible Debentures On September 22, 2021, the Company issued a non-convertible promissory note in the amount of $ 2,500,000 bearing interest of 15% per annum and payable at maturity. The promissory note matured on March 15, 2022 ; however, the note holder agreed to accept $ 500,000 payment, which the Company paid, by April 15, 2022, and the remaining principal and interest was deferred to June 20, 2022. Interest expense for the three months ended March 31, 2022 and 2021 was $ 92,466 and $ nil , respectively. At March 31, 2022 interest of $ 195,205 is included in interest payable on the condensed consolidated balance sheet. $50,000,000 Project Finance Package On December 20, 2021, the Company executed a non-binding term sheet outlining a $ 50,000,000 The non-binding term sheet with SRSR outlined a $ 50,000,000 project financing package that the Company expects to fulfill the majority of its funding requirements to restart the Mine. The financing package consisted of an $ 8,000,000 royalty convertible debenture (the “RCD”), a $ 5,000,000 convertible debenture (the “CD”), and a multi-metals stream of up to $ 37,000,000 (the “Stream”, together with the RCD and the CD, the “Project Financing Package”). Total finance costs for legal fees associated with the two convertible debentures was $ 795,100 , of which $ 67,435 associated with the derivative portions of the financing was recognized as a period expense and $ 727,665 was allocated to the CD and RCD pro-ratably based on their fair value on the issuance date, with $ 300,579 427,086 $8,000,000 Royalty Convertible Debenture The Company closed the $ 8,000,000 RCD on January 7, 2022. The RCD bears interest at an annual rate of 9.0% , payable in cash or Common Shares at the Company’s option, until such time that SRSR elects to convert a royalty, with such conversion option expiring at the earlier of advancement of the Stream or 18 months. In the event of conversion, the RCD will cease to exist and the Company will grant a royalty for 1.85% of life-of-mine gross revenue from mining claims considered to be historically worked, contiguous to current accessible underground development, and covered by the Company’s 2021 ground geophysical survey (the “SRSR Royalty”). A 1.35% rate will apply to claims outside of these areas. The RCD is secured by a share pledge of the Company’s operating subsidiary, Silver Valley, until a full security package was put in place concurrent with the consummation of the CD. In the event of non-conversion, the principal of the RCD will be repayable in cash. $6,000,000 Convertible Debenture The Company closed the $ 6,000,000 CD on January 28, 2022, which was increased from the previously-announced $ 5,000,000 . The Convertible Debenture bears interest at an annual rate of 7.5% , payable in cash or shares at the Company’s option, and matures on July 7, 2023 . The CD is secured by a pledge of the Company’s properties and assets. Until the closing of the Stream, the CD is convertible into Common Shares at a price of C$ 0.30 per Common Share, subject to stock exchange approval. Alternatively, SRSR may elect to retire the CD with the cash proceeds from the Stream. The Company may elect to repay the CD early; if SRSR elects not to exercise its conversion option at such time, a minimum of 12 months of interest would apply. Bunker Hill Mining Corp. Notes to the Condensed Interim Consolidated Financial Statements (Unaudited) Three Months Ended March 31, 2022 (Expressed in United States Dollars) The Company determined that the conversion features in both the RCD and CD were not closely related to their respective debt components, and should be considered as derivatives under ASC 815. As such, these derivative components were bifurcated, accounted for and valued separately under the framework prescribed by ASC 820. The fair value of the derivative components in the RCD included the utilization of payable metal production estimates from the Company’s Preliminary Economic Assessment published in November 2022, and a Monte Carlo Simulation approach that included simulating the future prices of metals, and application of an appropriate project discount rate, as well as key inputs included in the table below. The value of the conversion feature in the CD was determined with the binomial model which involves the modelling of stock prices over the applicable term to evaluate the payouts under ‘hold’, ‘convert’, and ‘prepay’ decisions and select the decision that would maximize the fair value from a market participant’s perspective. The derivative components will be fair valued at each reporting period, with changes in fair value recorded as a gain or loss in the statement of profit or loss. The debt components of the RCD and CD were initially measured by first valuing the derivative components as described above, and are accounted for separately as financial liabilities that will be subsequently measured at amortized cost. Consistent with the approach above, the following table summarizes the key valuation inputs: Schedule of Key Valuation Inputs Reference (2)(4) (5) Valuation date Maturity date Contractual Stock price (US$) Expected equity volatility Credit spread Risk-free rate Risk-adjusted rate CD note (1)(3) 01-28-22 07-07-23 7.50 % 0.230 120 % 8.70 % 0.92 % 16.18 % RCD note (stream not advanced scenario) 01-07-22 07-07-23 9.00 % 0.242 130 % 9.21 % 0.65 % 16.39 % RCD note (stream advanced) scenario 01-07-22 06-30-22 9.00 % 0.242 130 % 9.16 % 0.23 % 15.96 % CD note (1)(3) 03-31-22 07-07-23 7.50 % 0.235 120 % 8.85 % 1.80 % 17.12 % RCD note (stream not advanced scenario) 03-31-22 07-07-23 9.00 % 0.235 120 % 8.85 % 1.80 % 17.12 % RCD note (stream advanced) scenario 03-31-22 06-30-22 9.00 % 0.235 120 % 8.78 % 0.52 % 15.88 % (1) The CD carries a Discount for Lack of Marketability (“DLOM”) of 5.0 (2) All instruments carry an instrument-specific spread of 7.23 (3) The conversion price of the CD is $ 0.235 (4) A project risk rate of 13.0 (5) The probabilities for the stream being advanced and the stream not being advanced is 55 45 The resulting fair values of the CD and RCD at the issuance dates, and as of March 31, 2022 were as follows: Schedule of Fair Value Derivative Liability Instrument Description Valuation Date Value of the Debt Component, Net of Finance Costs Value of the Embedded Derivatives Total Value CD January 28, 2022 4,991,976 1,028,252 6,020,228 RCD January 7,2022 7,092,978 159,129 7,252,107 Total 12,084,954 1,187,381 13,272,335 Instrument Description Valuation Date Value of the Debt Component Including Interest at Effective Rates(1) Value of the Embedded Derivatives Total Value CD March 31, 2022 5,173,075 997,614 6,170,689 RCD March 31,2022 7,379,995 263,236 7,643,231 Total 12,553,070 1,260,850 13,813,920 (1) The effect rates for the CD and RCD are 21.357 17.795 The Company performs quarterly testing of the covenants in the RCD and CD.

The promissory note was scheduled to mature on the earlier of March 15, 2022 ; however, the note holder agreed to accept $ 500,000 payment by April 15, 2022, and the remaining principal and interest was deferred to June 20, 2022. See Note 16 Subsequent Events concerning a financing anticipated to close on March 31, 2022. The Company purchased a land parcel for approximately $ 200,000 subsequent to December 31, 2021, which may be used as security for the promissory note. Interest expense for the year ended December 31, 2021 was $ 102,740 , which is reflected in Interest payable on the Company’s balance sheet at December 31, 2021. $50,000,000 Project Finance Package On December 20, 2021, the Company executed a non-binding term sheet with Sprott Resource Streaming and Royalty (“SRSR”) and other investors outlining a $ 50,000,000 project finance package that the Company expects to fulfill the majority of its funding requirements to restart the mine and reach commercial production in mid-2023. The package consists of an $ 8,000,000 5,000,000 37,000,000 (collectively, the “Stream”). Subject to settlement of definitive documentation with SRSR, the $ 8,000,000 was advanced under the Royalty Convertible Debenture in January 2022. These proceeds funded the purchase of the Bunker Hill Mine and near-term working capital requirements, including a $ 2,000,000 payment to the EPA in January 2022. The Royalty Convertible Debenture will initially bear interest at an annual rate of 9.0 %, payable in cash or shares at the Company’s option, until such time that SRSR elects to convert it into a Royalty, with such conversion option expiring at the earlier of advancement of the Stream or 18 months. In the event of conversion, the Royalty Convertible Debenture will cease to exist and the Company will grant a Royalty for 1.85 % of life-of-mine gross revenue from mining claims considered to be historically worked, contiguous to current accessible underground development, and covered by the Company’s 2021 ground geophysical survey. A 1.35% rate will apply to claims outside of these areas. The Royalty Convertible Debenture will initially be secured by a share pledge of the Company’s operating subsidiary, until such time that a full security package is put in place. In the event of non-conversion, the principal of the Royalty Convertible Debenture will be repayable in cash. Subject to settlement of definitive documentation with SRSR and other investors, the $ 5,000,000 was increased to $ 6,000,000 , and was advanced under the Convertible Debenture, also in January 2022. These proceeds will fund capital expenditures and working capital requirements in Q1 2022. The Convertible Debenture will bear interest at an annual rate of 7.5 %, payable in cash or shares at the Company’s option, and a maturity of 18 months from the closing of the Royalty Convertible Debenture. Until the closing of the Stream, the Convertible Debenture is convertible into shares of the Company at a share price of CAD 0.30 per share. Alternatively, SRSR may elect to retire the Convertible Debenture with the cash proceeds of the Stream. The Company may elect to re-pay the Convertible Debenture early; if SRSR elects not to exercise its conversion option at such time, a minimum of 12 months of interest would apply. Subject to SRSR internal approvals, further technical and other diligence (including confirmation of full project funding by an independent engineer appointed by SRSR), and satisfactory definitive documentation, the Company expects to close the Stream concurrent with a formal construction decision being made by Q2 2022. A minimum of $ 27,000,000 and a maximum of $ 37,000,000 (the “Stream Amount”) will be made available under the Stream, at the Company’s option, once the conditions for availability of the Stream have been satisfied. Assuming the maximum funding of $37,000,000 is drawn, the Stream would apply to 10% of payable metals sold until a minimum quantity of metal is delivered consisting of, individually, 55 million pounds of zinc, 35 million pounds of lead, and 1 million ounces of silver. 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. The Company will be permitted to incur additional indebtedness of $ 15,000,000 13,000,000 The Royalty Convertible Debenture and Convertible Debenture closed subsequent to the end of the year. See Note 16 Subsequent Events. In support of plans to rapidly restart the Mine, the Company worked systematically through 2020 and 2021 to delineate mineral resources and conduct various technical studies. Executing this strategy may require securing additional financing, which may include additional indebtedness of $ 15,000,000 13,000,000 |

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 (formerly 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. As at March 31, 2022 and December 31, 2021, $ 5,185,709 and $ 5,110,706 , respectively, is payable to the EPA and IDEQ, which has been included in accounts payable and accrued liabilities. The majority of these amounts relate to the EPA, given that they primarily relate to costs incurred through December 2021. The Company pays a lease under a lease agreement which expires in May 2022 .

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.

On August 13, 2021, the Company filed a motion to dismiss the claim for lack of jurisdiction and standing. On September 3, 2021, the plaintiff responded to the motion to dismiss and agreed that Placer Mining should be dismissed for lack of jurisdiction. The Company, as well as other named defendants, filed replies in support of the motions to dismiss and argued that Placer Mining is an indispensable party and with dismissal of Placer Mining the lawsuit should be dismissed. The US District Court has not ruled on the motions to dismiss but the Company believes the motion to dismiss will be granted and the lawsuit dismissed.

The terms of the purchase price were modified to $5,400,000 in cash, from $3,400,000 of cash and $2,000,000 of Common Shares. The purchase price of the mine totaled $7,342,638 was capitalized, after taking into effect the deposits previously made, the credits given and closing costs. Additionally, a total of $442,147 of legal costs were capitalized . Concurrent with the purchase of the Mine, the Company assumed the balance of the EPA liability totaling $17,000,000 (after the payment of the $2,000,000 on January 7, 2022), an increase of $8,000,000 of which $3,000,000 is current liability and $5,000,000 is long-term in nature. The long-term portion was discounted at an interest rate of 16.5% to arrive at a net present value of $3,402,425 after discount. During the quarter ended March 31, 2022, $138,427 of the discount was amortized to interest expense. At Marc h 31, 2022, the total EPA cost recovery liability was $ 17,000,000 1,457,147 15,540,853 The current portion of the EPA cost recovery liability at March 31, 2022 was $ 12,000,000 Schedule Of Environmental Cost Recover Liability Amount EPA cost recovery payable at December 31, 2021 $ 11,000,000 Payment as part of mine purchase on January 7, 2022 (2,000,000 ) Assumed with mine purchase – current portion 3,000,000 EPA cost recovery at March 31, 2022 $ 12,000,000 The balance of the NPV of the long-term portion of the EPA cost recovery payable at March 31, 2022 was $ 3,540,853 Schedule Of Net Present Value of Environmental Protection Agency Agreement Amount Long-term portion of NPV of EPA cost recovery payable at purchase of mine on January 7, 2022 $ 3,402,425 Accretion of NPV discount during the quarter 138,427 Long-term portion of NPV of EPA cost recovery payable at March 31, 2022 $ 3,540,853 In addition to these payments, the Company makes a monthly accrual of $ 165,000 140,000 The balance of EPA/IDEQ water treatment liability at March 31, 2022 was $ 5,185,706 Schedule Of EPA/IDEQ Water Treatment Liability Amount EPA/IDEQ water treatment liability at December 31, 2021 $ 5,110,706 Payments during the quarter (420,000 ) Accruals during the quarter 495,000 EPA/IDEQ water treatment liability at March 31, 2022 $ 5,185,706 Bunker Hill Mining Corp.

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 has been in the exploration stage since its formation on February 20, 2007 and has not yet realized any revenues from its planned operations. It is primarily engaged in the acquisition and exploration of mining properties. 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 loss and comprehensive 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 cash flow models used to assess impairment. The ability to achieve the estimated quantities of recoverable minerals from exploration 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, accounts receivable excluding HST, accounts payable, accrued liabilities, interest payable, convertible loan payable, promissory notes payable, lease liability, and other liabilities, 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 Company measured its DSU liability at fair value on recurring basis using level 1 inputs and derivative warrant liabilities 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, 2021, December 31, 2020, and June 30, 2020, the Company has not taken any tax positions that would require disclosure under FASB ASC 740. |
Basic and diluted net loss per share | Basic and diluted net loss per share The Company computes net loss per share in accordance with FASB ASC 260, Earnings per Share (“FASB ASC 260”). Under the provisions of FASB ASC 260, basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net 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 and warrants and the conversion of convertible loan payable. As of December 31, 2021, 9,053,136 111,412,712 3,590,907 8,015,159 95,777,806 3,239,907 |
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 and assumptions | Use of estimates and assumptions 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 and conversion feature derivative 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 and conversion feature derivative liability, volatility and dividend yield and making assumptions about them. The assumptions and models used for estimating fair value of warrants and conversion feature derivative liability are disclosed in notes 8 and 10. 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. 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 mineralized material exploration industry that is subject to significant risks and uncertainties, including financial, operational, and other risks associated with operating a mineralized material 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 conversion option, that are required to be bifurcated and accounted for as individual derivative financial instruments. In circumstances where the convertible debt 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. 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 presents its embedded derivatives and related debenture host contracts as separate instruments on the consolidated balance sheets. |
