Bunker Hill Mining Corp. (Formerly Liberty Silver Corp.)

Notes to Unaudited Interim Condensed Consolidated Financial Statements

For the Six Months Ended December 31, 2017

Note 1 – Basis of Presentation and Going Concern

The accompanying unaudited interim condensed consolidated financial statements 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’ equity 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 interim condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, which contains the annual audited financial statements and notes thereto, together with the Management’s Discussion and Analysis, for the year ended June 30, 2017. The interim results for the period ended December 31, 2017 are not necessarily indicative of the results for the full fiscal year. The interim unaudited condensed consolidated financial statements are presented in USD, which is the functional currency.

These unaudited interim condensed consolidated financial statements have been prepared on a going concern basis. The Company has incurred losses since inception resulting in an accumulated deficit of $21,837,898 and further losses are anticipated in the development of its business. The ability of the Company to emerge from the exploration stage is dependent upon, among other things, obtaining additional financing to continue operations, explore and develop the mineral properties and the discovery, development, and sale of reserves. In order to continue to meet its plans and fiscal obligations in the current fiscal year and beyond, the Company must seek additional financing. 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 unaudited condensed consolidated interim 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 interim condensed 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, obtaining additional financing to continue operations, explore and develop the mineral properties and the discovery, development, and sale of reserves.  These factors, among others, raise substantial doubt about the Company’s ability to continue as a going concern.

Note 2 – Nature of Operations

Bunker Hill Mining Corp. (formerly Liberty Silver Corp.) (the “Company” or “Bunker”) was incorporated under the laws of the state of Nevada U.S.A, 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 401 Bay82 Richmond Street Suite 2702,East, Toronto, Ontario, Canada, M5H 2Y4, and its telephone number is 888-749-4916.M5C 1P1. As of the date of this Form 10-K,10-Q, the Company had two subsidiaries, Bunker Hill Operating LLC, a Colorado corporation that is currently dormant, andone subsidiary, Silver Valley Metals Corp. (“Silver Valley”, formerly American Zinc.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 purpose of engaging in mineral exploration activities. It continues to work at developing its projectsproject with a view towards putting themit 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 $59,626,902 and further losses are anticipated in the development of its business. Additionally, the Company owes a total of $3,847,141 to the Environmental Protection Agency (“EPA”) (see Note 6) for water treatment that is classified as current. The Company also owes a total of $7,420,024, 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 unaudited 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, debt, and closing on the multi-metals stream transaction (see note 7). These unaudited condensed 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.

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.

Three and Nine Months Ended September 30, 2022

(Expressed in United States Dollars)

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 sheet as a 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.

At September 30, 2022, the asset consists of the following:

5. Mining Interests

Bunker Hill Mine Complex

The Company purchased the Bunker Hill Mine located(the “Mine”) in Kellogg, Idaho, inJanuary 2022, as described below.

Prior to purchasing the Coeur d’Alene Basin (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.

The Company made certain payments totaling $300,000 as part of this Letter of Intent.  During the quarter ended September 30, 2017, additional payments totaling $200,000 were made to extend the negotiation period.  On August 28, 2017, the Company announced that it signedhad entered into a definitive agreement (the “Agreement”series of agreements with Placer Mining Corporation (“Placer Mining”), the prior owner, for the lease and option to purchase the Mine. The first of these agreements was announced on August 28, 2017, with subsequent amendments and/or extensions announced on November 1, 2019, July 7, 2020, and November 20, 2020.

Under the terms of the November 20, 2020 amended agreement (the “Amended Agreement”), a purchase price of $7,700,000 was agreed, with $5,700,000 payable in cash (with an aggregate of $300,000 to be credited toward the purchase price of the Mine as having been previously paid by the Company) and $2,000,000 in Common Shares of the Company. The Company agreed to make an advance payment of $2,000,000, credited towards the purchase price of the Mine, which had the effect of decreasing the remaining amount payable to purchase the Mine to an aggregate of $3,400,000 payable in cash and $2,000,000 in Common Shares of the Company.

The Amended Agreement also required payments pursuant to an agreement with the EPA whereby for so long as the Company leases, owns and/or occupies the Mine, the Company would make payments to the EPA on behalf of Placer Mining in satisfaction of the EPA’s claim for historical water treatment cost recovery in accordance with the Settlement Agreement reached with the EPA in 2018. Immediately prior to the purchase of the Mine, the Company’s liability to EPA in this regard totaled $11,000,000. (See also Note 6 Environmental Protection Agency Agreement and Water Treatment Liabilities).

The Company completed the purchase of the Mine on January 7, 2022. 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. Concurrent with the purchase of the Mine, the Company assumed incremental liabilities of $8,000,000 to the EPA, consistent with the terms of the amended Settlement Agreement with the EPA that was executed in December 2021 (see “EPA Settlement Agreement” section below).

The $5,400,000 contract cash paid at purchase was the $7,700,000 less the $2,000,000 deposit and $300,000 credit given by the seller for prior years’ maintenance payments. The carrying cost of the Mine is comprised of the following:

Schedule of Mining Interests

Management has determined the purchase to be an acquisition of a single asset as guided by ASU 805-10. During the three and nine months ended September 30, 2022, the Company has spent an additional $356,149 and $356,149, respectively, in mine improvements.

Land Purchase

On March 3, 2022, the Company purchased a 225-acre surface land parcel for $202,000 which includes the surface rights to portions of 24 patented mining claims, for which the Company already owns the mineral rights.

6. Environmental Protection Agency Agreement and Water Treatment Liabilities

Historical Cost Recovery Payables

As a part of the lease of the Mine, the Company was required to make payments pursuant to an agreement with the Environmental Protection Agency (the “EPA”) whereby for so long as the Company leases, owns and/or occupies the Mine, the Company was required to make payments to the EPA on behalf of Placer Mining in satisfaction of the EPA’s claim for cost recovery related to historical treatment costs paid by the EPA from 1995 to 2017. These payments, if all are made, will total $20,000,000. The agreement called for payments starting with $1,000,000 30 days after a fully ratified agreement was signed (which payment was made) followed by $2,000,000 on November 1, 2018, and $3,000,000 on each of the next five anniversaries with a final $2,000,000 payment on November 1, 2024. The November 1, 2018, November 1, 2019, November 1, 2020, and November 1, 2021, payments were not made. As a result, a total of $11,000,000 was outstanding as of December 31, 2021, accounted for within current liabilities. As the purchase of the Bunker Hill Mine assets (the “Bunker Assets”)(see note 5). All payments related(which would trigger the immediate recognition of the remaining liabilities due through November 1, 2024) had not yet taken place, the remaining $8,000,000 cost recovery liabilities were not recognized on the Company’s balance sheet as of December 31, 2021.

Three and Nine Months Ended September 30, 2022

(Expressed in United States Dollars)

Through 2021, the option is exercisedCompany engaged in discussions with the EPA to reschedule these payments in ways that enable the sustainable operation of the Mine as a viable long-term business.

Effective December 19, 2021, the Company entered into an amended Settlement Agreement between the Company, Idaho Department of Environmental Quality, US Department of Justice, and the $500,000 previously capitalized hasEPA (the “Amended Settlement”). Upon the effectivity of the Amended Settlement, the Company would become fully compliant with its payment obligations to these parties. The Amended Settlement modified the payment schedule and payment terms for recovery of the aforementioned historical environmental response costs. Pursuant to the terms of the Amended Settlement, upon purchase of the Bunker Hill Mine and the satisfaction of financial assurance commitments (as described below), the $19,000,000 of cost recovery liabilities will be paid by the Company to the EPA on the following dates:

Schedule of Amended Settlement Environmental Protection Agency Agreement

In addition to the changes in payment terms and schedule, the Amended Settlement included a commitment by the Company to secure $17,000,000 of financial assurance in the form of performance bonds or letters of credit deemed acceptable to the EPA within 180 days from the effective date of the Amended Settlement Agreement. Once put in place, the financial assurance can be drawn on by the EPA in the event of non-performance by the Company of its payment obligations under the Amended Settlement (the “Financial Assurance”). The amount of the bonds will decrease over time as individual payments are made.

The Company completed the purchase of the Mine (see note 5) and made the initial $2,000,000 cost recovery payment on January 7, 2022. Concurrent with the purchase of the Mine, the Company assumed the balance of the EPA liability totaling $17,000,000, an increase of $8,000,000.

As of March 31, 2022, the financial assurance had not yet been expensedsecured, and as such the Company accounted for the $17,000,000 liabilities according to the previous payment schedule, resulting in $12,000,000 classified as a current liability and $5,000,000 as a long-term liability. 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 June 30, 2022, the Company was successful in obtaining the final financial assurance. Specifically, a $9,999,000 payment bond and a $7,001,000 letter of credit were secured and provided to the EPA. This milestone provides for the Company to recognize the effects of the change in terms of the EPA liability as outlined in the December 19, 2021 agreement. Once the financial assurance was put into place, the restructuring of the payment stream under the Amendment occurred with the entire $17,000,000 liability being recognized as long-term in nature. The aforementioned payment bond is secured by a $2,475,000 letter of credit. The $2,475,000 and $7,001,000 letters of credit are secured by $9,476,000 of cash deposits under an agreement with a commercial bank. These cash deposits comprise the $9,476,000 of restricted cash shown within current assets as of September 30, 2022.

Under ASC 470-50, Debt Modifications and Extinguishments, the Company performed a comparison of NPV’s of the pre-settlement Cost Recovery obligation to the post-settlement schedule of Cost Recovery obligation to determine this was an extinguishment of debt. The Company recorded a gain on extinguishment of debt totaling $8,614,103. The old debt, including any discount, was written off and the new payment stream of the amended $17,000,000 table, including the new discount of $9,927,590, using the effective interest rate of 19.95%, was recorded to result in a net liability of $7,072,410, which is due long-term. During the three and nine months ended September 30, 2022, the Company recorded combined discount amortization expense of $347,614 and $631,701 on the discounted pre- and post-extinguishment liability, respectively, bringing the net liability to $7,420,024 as of September 30, 2022. As at September 30, 2022 interest of $192,923 ($306,501 at December 31, 2017.2021) is included in interest payable on the condensed consolidated balance sheet.

Water Treatment Charges – EPA

Separate to the cost recovery liabilities outlined above, the Company negotiated an extensionis responsible for the payment of ongoing water treatment charges. Water treatment charges incurred through December 31, 2021 are payable to the commencementEPA, and charges thereafter are payable to the Idaho Department of Environmental Quality (“IDEQ”) given a handover of responsibilities for the Central Treatment Plant from the EPA to the IDEQ as of that date. The Company previously estimated a balance due to the EPA of $5,110,706 for ongoing water treatment through December 31, 2021. During the six months ended June 30, 2022, the Company received an invoice from the EPA for water treatment through October 2021. As a result, the Company reversed its previous accruals for this period and adjusted its estimated charges for November and December 2021. Through recent discussions with the EPA, the Company has confirmed that payments to the IDEQ for water treatment charges cannot be netted against invoices payable to the EPA. After taking this into account, the additional invoice received from the EPA, and a $1,000,000 payment made in April 2022, the Company has estimated water treatment payables to the EPA of $3,847,141 as of September 30, 2022 and $5,110,706 at December 31, 2021, which is reflected in current liabilities.

Water Treatment Charges – IDEQ

For water treatment charges beginning January 2022, the Company makes a monthly accrual of $80,000 to cover the IDEQ’s estimated costs of treating water at the water treatment facility. The Company also pays an agreed-upon monthly amount of $140,000, with a true-up to be recorded and credited to or paid by the Company once the actual annual costs are determined each year. At September 30, 2022, the Company has accrued $720,000 for water treatment costs to IDEQ and has prepaid $1,260,000, leaving a net prepaid of $540,000 ($nil at December 31, 2021) which is included in prepaid expenses on the unaudited condensed interim consolidated balance sheet.

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 was scheduled to mature 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. Prior to the revised maturity of June 20, 2022, the note holder agreed to accept a further $500,000 payment by June 30, 2022, which the Company paid, and the remaining principal and interest was deferred to November 30, 2022. The Company purchased a land parcel for approximately $202,000 on March 3, 2022, which may be used as security for the promissory note. At September 30, 2022, the Company owes $1,500,000 in promissory notes payable, which is included in current liabilities on the condensed consolidated balance sheet. Interest expense for the three and nine months ended September 30, 2022 was $56,712 and $224,589, respectively. For the three and nine months ended September 30, 2021, interest expense was $8,219 and $8,219, respectively. At September 30, 2022 interest of $327,329 ($102,740 at December 31, 2021) is included in interest payable on the condensed consolidated balance sheet.

Project Finance Package with Sprott Private Resource Streaming & Royalty Corp.

On June 17, 2022, the Company consummated a new $15,000,000 convertible debenture (the “CD2”). As a result, total potential funding from SRSR was further increased to $66,000,000 including the RCD, CD1, CD2 and the Stream (together, the “Project Financing Package”).

$8,000,000 Royalty Convertible Debenture (RCD)

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 leaseStream or July 7, 2023 (subsequently amended as described below).

A 1.35% rate will apply to claims outside of these areas. The RCD was initially 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 CD1. In the event of non-conversion, the principal of the RCD will be repayable in cash.

$6,000,000 Series 1 Convertible Debenture (CD1))

The Company closed the $6,000,000 CD1 on January 28, 2022, which was increased from the previously-announced $5,000,000.

The Company determined that the amendments in the terms of the RCD should not be treated as an extinguishment of the CD1, and have therefore been accounted for as a modification as a result of the treatment the Company reported a gain of $179,046 in the statement of operations for the period ended September 30, 2022

The Stream

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 of availability of the Stream have been satisfied, including confirmation of full project funding by an independent engineer appointed by SRSR. If the Company draws the maximum funding of $37,000,000, 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 (subsequently amended, as described below). 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. As of September 30, 2022, the Stream had not been advanced.

Concurrent with the funding of the CD2 in June 2022, the Company and SRSR agreed that the minimum quantity of metal delivered under the Stream, if advanced, will increase by 10% relative to the amounts noted above.
