Nature and continuance of operations and going concern

Bunker Hill Mining Corp.

(the “Company”) was incorporated under the laws of the state of Nevada, U.S.A on February 20, 2007 under the name Lincoln Mining Corp.

Pursuant to a Certificate of Amendment dated February 11, 2010, the Company changed its name to Liberty Silver Corp., and on September 29, 2017 the Company changed its name to Bunker Hill Mining Corp.

The Company’s registered office is located at 1802 N.

Carson Street, Suite 212, Carson City Nevada 89701, and its head office is located at 401 Bay Street, Suite 2702, Toronto, Ontario, Canada, M5H 2Y4.

As of the date of this Form 10-Q, the Company had two subsidiaries, Bunker Hill Operating LLC, a Colorado corporation that is currently dormant, and American Zinc Corp., an Idaho corporation created to facilitate the work being conducted at the Bunker Hill Mine in Idaho.

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.

These unaudited condensed interim consolidated financial statements have been prepared on a going concern basis.

Bunker Hill Mining Corp.

(the "Company") has incurred losses since inception resulting in an accumulated deficit of $64,192,278 and further losses are anticipated in the development of its business.

under the name Lincoln Mining Corp.

Pursuant to a Certificate of Amendment dated February 11, 2010, the Company changed its name

to Liberty Silver Corp., and on September 29, 2017 the Company changed its name to Bunker Hill Mining Corp.

The Company’s

registered office is located at 1802 N.

Carson Street, Suite 212, Carson City Nevada 89701, and its head office is located at

82 Richmond Street East, Toronto, Ontario, Canada, M5C 1P1.

As of the date of this Form 10-Q, the Company had one subsidiary,

Silver Valley Metals Corp.

at the Bunker Hill Mine in Idaho.

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.

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 $60,251,064 and further losses are anticipated in the development

of its business.

The Company does not have sufficient working capital needed to meet its current fiscal obligations and commitments.

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 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, obtaining additional financing to continue operations, explore and develop the mineral properties and the discovery, development, and sale of reserves.

The Company’s operations could be significantly adversely affected by the effects of a widespread global outbreak of a contagious disease, including the recent outbreak of respiratory illness caused by 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.

Basis of presentation

The accompanying unaudited condensed interim 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 condensed interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Amended Form 10-K/A, which contains the annual audited consolidated financial statements and notes thereto, together with the Management’s Discussion and Analysis, for the year ended June 30, 2020.

The interim results for the period ended September 30, 2020 are not necessarily indicative of the results for the full fiscal year.

The unaudited interim condensed consolidated financial statements are presented in USD, which is the functional currency.

New and recently adopted technical and accounting pronouncements

On July 1, 2020, the Company adopted Account Standards Update (ASU) 2016-03, Financial Instruments - Credit Losses (Topic 326):

Measurement of Credit Losses on Financial Instruments ("ASU 2016-13").

ASU 2016-13 changed the impairment model for most financial instruments.

Previous guidance required the recognition of credit losses based on an incurred loss impairment methodology that reflects losses once the losses are probable.

Under ASU 2016-13, the Company is required to use a current expected credit loss ("CECL") model that immediately recognizes an estimate of credit losses that are expected to occur over the life of the financial instruments that are in the scope of the update, including trade receivables.

The CECL model uses a broader range of reasonable and supportable information in the development of credit loss estimates.

The adoption of ASU 2016-13 did not have a material impact on the unaudited condensed interim consolidated financial statements, as the Company's accounts receivable only consisted of sales taxes receivable.

Restatement of previously issued financial statements

In November 2020, it was determined that the Company has underaccrued for invoices issued by the United States Environmental Protection Agency ("EPA") for excess water treatment costs relating to years ended June 30, 2018, 2019 and 2020, interest payable on the outstanding EPA balance, and for a finder's fee related to the Company's February 2020 private placement, which resulted in an understatement of liabilities for 2019 and 2020, an overstatement of additional paid-in-capital for 2020, an understatement of opening and closing deficit for 2019 and 2020, and an understatement of exploration expenses and net losses for 2019 and 2020.

The following tables present the impact of the restatement adjustments on the Company's previously issued condensed interim consolidated financial statements for the three months ended September 30, 2019.

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 (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 as part of this Letter of Intent.

These amounts were initially capitalized and subsequently written off during fiscal 2018 and were included in exploration expenses.

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 million bonus payment to Placer Mining no later than October 31, 2017, which payment was made, along with two additional $500,000 bonus payments in December 2017.

The 24-month lease commenced November 1, 2017.

During the term of the lease, the Company was to $100,000 monthly mining lease payments, paid quarterly.

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 million with purchase payments to be made over a ten-year period to Placer Mining.

Under terms of the agreement, there is a 3% net smelter return royalty (“NSR”) on sales during the Lease and a 1.5% NSR on the sales after the purchase option is exercised, which post-acquisition NSR is capped at $60 million.

On October 2, 2018, the Company announced that it was in default of its Lease with Option to Purchase Agreement with Placer Mining.

The default arose as a result of missed lease and operating cost payments, totaling $400,000, which were due at the end of September and on October 1, 2018.

As per the Agreement, the Company had 15 days, from the date notice of default was provided (September 28, 2018), to remediate the default by making the outstanding payment.

While Management worked with urgency to resolve this matter, Management was ultimately unsuccessful in remedying the default, resulting in the lease being terminated.

On November 13, 2018, the Company announced that it was successful in renewing the lease, effectively with the original Agreement intact, except that monthly payments are reduced to $60,000 per month for 12 months, with the accumulated reduction in payments of $140,000 per month (“deferred payments”) being accrued.

As at September 30, 2020, the Company has accrued for a total of $1,787,300 (June 30, 2020 - $1,847,300), which is included in accounts payable.

These deferred payments will be waived should the Company choose to exercise its option.

On October 22, 2019, the Company signed a further amendment to the Agreement.

The key terms of this amended agreement are as follows:

* The lease period has been extended for an additional period of nine months to August 1, 2020, with the option to extend for a further 6 months based upon payment of a 1 time $60,000 extension fee (extended).

* The Company will continue to make monthly care and maintenance payments to Placer Mining of $60,000 until exercising the option to purchase.

* The purchase price is set at $11 million for 100% of the marketable assets of Bunker Assets to be paid with $6,200,000 in cash, and $4,800,000 in shares.

The purchase price also includes the negotiable EPA costs of $20 million.

The amended lease provides for the elimination of all royalty payments that were to be paid to the mine owner.

Upon signing the amended agreement, the Company paid a one-time, non-refundable cash payment of $300,000 to the mine owner.

This payment will be applied to the purchase price upon execution of the purchase option.

In the event the Company elects not to exercise the purchase option, the payment shall be treated as an additional care and maintenance payment.

On August 12, 2020, the Company extended the lease with Placer Mining for further 18 months for a $150,000 extension fee.

This extension expires on August 1, 2022.

In addition to the payments to Placer Mining, and pursuant to an agreement with the United States Environmental Protection Agency (“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 million.

The agreement calls for payments starting with $1 million 30 days after a fully ratified agreement was signed followed by a payment schedule detailed below:

the Company had 15 days, from the date notice of default was provided (September 28, 2018), to remediate the default by making

the outstanding payment.

While management worked with urgency to resolve this matter, management was ultimately unsuccessful in

remedying the default, resulting in the Agreement being terminated.

November 13, 2018, the Company announced that it was successful in renewing the Agreement, effectively with the original Agreement

intact, except that 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.

of $nil (December 31, 2020 - $nil), which is included in accounts payable.

These deferred payments will be waived should

Deferred share units

Effective April 21, 2020, the Board of Directors approved a Deferred Share Unit ("DSU") Plan to grant DSUs to its directors.

The DSU Plan permits the eligible directors to defer receipt of all or a portion of their retainer or compensation until termination of their services and to receive such fees in the form of cash at that time.

Upon vesting of the DSUs or termination of service as a director, the director will be able to redeem DSUs based upon the then market price of the Company's common share on the date of redemption in exchange for cash.

The following table summarizes the DSU activity during the periods ended September 30, 2020:

Unvested as at June 30, 2019 and September 30, 2019

Company was incorporated for the purpose of engaging in sustainable mineral exploration, development and mining activities.

Company’s sole focus is the Bunker Hill mine and assets related thereto (the “Mine”), as described below.

August 28, 2017, the Company announced that it signed a definitive agreement with Placer Mining Corporation (“Placer Mining”),

the current owner of the Mine, for the lease and option to purchase the Mine in Idaho (the “Lease and Option Agreement”).

November 1, 2019, the Lease and Option Agreement was amended (the “Amended Agreement”).

Under the terms of the Amended

Agreement, the Company has an option to purchase the marketable assets of the Mine for a purchase price of $11,000,000 at any

time prior to the expiration of the Amended Agreement, payable $6,200,000 in cash, and $4,800,000 in unregistered Common Shares

of the Company (calculated using the market price at the time of exercise of the purchase option).

Upon signing the Amended Agreement,

the Company paid a one-time, non-refundable cash payment of $300,000 to Placer Mining.

This payment will be applied to the cash

portion of the purchase price upon execution of the purchase option.

In the event the Company elects not to exercise the purchase

option, the payment shall be treated as an additional care and maintenance payment.

An additional term of the Amended Agreement

provides for the elimination of all royalty payments that were to be paid to Placer Mining.

the terms of the Amended Agreement, during the term of the lease, the Company must make care and maintenance payments in the amount

of $60,000 monthly plus other expenses, i.e., taxes, utilities and mine rescue payments.

July 27, 2020, the Company announced that it secured, for a $150,000 cash payment, a further extension to the Lease and Option,

Amended and Extension Agreements to purchase the Mine from Placer Mining (the “Second Extension”).

The Second Extension

is for a further 18 months and is in addition to the 6-month extension.

This Second Extension expires on August 1, 2022.

November 20, 2020, the Company successfully renegotiated the Amended Agreement.

Under the new terms, the purchase price has been

decreased from $11,000,000 to $7,700,000, 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 an aggregate of $5,400,000 payable in cash outstanding)

and $2,000,000 in Common Shares of the Company.

The reference price for the payment in Common Shares will be based on the share

price of the last equity raise before the option is exercised.

The Company will continue to make a monthly care and maintenance

payment of $60,000 to the Lessor in return for on-going technical support to the Company.

Under this amendment to the Amended

Agreement, the Company’s contingent obligation to settle $1,787,300 of accrued payments due to the Lessor has been waived.

Further, under the amendment to the Amended Agreement, the Company is to make an advance payment of $2,000,000 to Placer Mining,

which shall be credited toward the purchase price of the Mine when the Company elects to exercise its purchase right.

that the Company irrevocably elects not to exercise its purchase right, the advance payment of $2,000,000 will be repaid to the

Company within twelve months from the date of such election.

The Company made this advance payment, 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.

a part of the purchase price, the Amended Agreement also requires payments pursuant to an agreement with the U.S.

Environmental

Protection Agency (“EPA”) whereby for so long as the Company leases, owns and/or occupies the Mine, the Company will

make payments to the EPA on behalf of Placer Mining in satisfaction of the EPA’s claim for cost recovery.

These payments,

if all are made, will total $20,000,000.

The agreement calls 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 5

anniversaries with a final $2,000,000 payment on November 1, 2024.

In addition to these 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 estimated costs of maintaining and treating

water at the water treatment facility with a true-up to be paid by the Company once the actual costs are determined.

1, 2018, December 1, 2018, June 1, 2019, November 1, 2019 and November 1, 2020 payments, totaling $8,960,000, were not made, and

concurrent with discussions concerning the long-term water management solutions the Company is having discussions with the EPA

in an effort to reschedule these payments in ways that enable the sustainable operation of the Mine as a viable long-term business.

believes the Amended Agreement will provide the Company time to complete exploratory drilling, engineering studies, produce a

mine plan and raise the money needed to move forward.

Management continues to push forward and advance the timeline to realizing

shareholder value.

Mine remains the largest single producing mine by tonnage in the Coeur d’Alene lead, zinc and silver mining district in

Northern Idaho.

Historically and according to the Bunker Hill Mines Annual Report 1980, the Mine produced over 35,000,000 tonnes

of ore grading on average 8.76% lead, 3.67% zinc, and 155 g/t silver.

The Mine is the Company’s only focus, with a view

to raising capital to rehabilitate the mine and put it back into production.

Company believes that there are numerous exploration targets of opportunity left in the Mine from surface, in parallel to known

and mined mineralization and at depth, below existing workings.

In addition to the zinc-rich zones, these also include high-grade

lead-silver veins which are currently the primary focus of the Company’s exploration programs.

Mine is a lead-silver-zinc Mine.

When back in production, the Company intends to mill mineralized material on-site or at a local

third-party mill to produce both lead-silver and zinc concentrates which will then be shipped to third party smelters for processing.

Company will continue to explore the property with a view to proving additional resources.

Infrastructure

acquisition of the Mine includes all mining rights and claims, surface rights, fee parcels, mineral interests, easements, existing

infrastructure at Milo Gulch, and the majority of machinery and buildings at the Kellogg Tunnel portal level, as well as all equipment

and infrastructure anywhere underground at the Bunker Hill Mine Complex.

The acquisition also includes 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.

Regulation and Approval

current exploration activities and any future mining operations are subject to extensive laws and regulations governing the protection

of the environment, waste disposal, worker safety, mine construction, and protection of endangered and protected species.

Company has made, and expects to make in the future, significant expenditures to comply with such laws and regulations.

changes in applicable laws, regulations and permits or changes in their enforcement or regulatory interpretation could have an

adverse impact on the Company’s financial condition or results of operations.

It is anticipated that it may be necessary

to obtain the following environmental permits or approved plans:

● Reclamation

and Closure Plan

Discharge Permit

Quality Operating Permit

Water Rights for Operations

Amended Agreement includes mineral rights to approximately 440 patented mining claims covering over 5700 acres.

Of these claims,

35 include surface ownership of approximately 259 acres.

The transaction also includes certain parcels of fee property which includes

mineral and surface rights but not patented mining claims.

Mining claims and fee properties are located in Townships 47, 48 North,

Range 2 East, Townships 47, 48 North, Range 3 East, Boise Meridian, Shoshone County, Idaho.

Amended Agreement specifically excludes the following:

the Machine Shop Building and Parcel number 21 including all fixed equipment

located inside the building and personal property located upon this parcel;

unmilled ore located at the Mine yard;

lead/zinc ore mined and broken, but not removed from the Mine.

rights were originally owned by various previous owners of the claims until the acquisition of the properties by Bunker Limited

Partners (“BLP”).

BLP sold off surface rights to various parties over the years while maintaining access to conduct

mining operations and exploration activities as well as easements to a cross over and access other of its properties containing

mineral rights.

Said rights were reserved to its assigns and successors in continuous perpetuity.

Idaho Law also allows mineral

right holders access to mine and explore for minerals on properties to which they hold minerals rights.

mining claims in the State of Idaho do not require permits for underground mining activities to commence on private lands.

permits associated with underground mining may be required, such as water discharge and site disturbance permits.

The water discharge

is being handled by the EPA at the existing CTP.

The Company expects to take on the water treatment responsibility in the future

and obtain an appropriate discharge permit.

Company competes with other mining and exploration companies in connection with the acquisition of mining claims and leases on

zinc and other base and precious metals prospects as well as in connection with the recruitment and retention of qualified employees.

Many of these companies are much larger than the Company, have greater financial resources and have been in the mining business

for much longer than it has.

As such, these competitors may be in a better position through size, finances and experience to acquire

suitable exploration and development properties.

The Company may not be able to compete against these companies in acquiring new

properties and/or qualified people to work on its current project, or any other properties that may be acquired in the future.

the size of the world market for base precious metals such as silver, lead and zinc, relative to the number of individual producers

and consumers, it is believed that no single company has sufficient market influence to significantly affect the price or supply

of these metals in the world market.

Company has three employees in executive positions.

The balance of the Company’s operations is contracted for as consultants.

Work and Future Plan of Operations

as of January 12, 2021, the Board appointed Mr.

David Wiens to the role of Chief Financial Officer and Corporate Secretary of

the Company, replacing Mr.

Wayne Parsons, who continues to serve on the Board.

February 24, 2021, the Company closed a non-brokered private placement of 19,994,080 Units of the Company at $0.40 per Unit for

gross proceeds of approximately C$8,000,000.

Each Unit consists of one Common Share of the Company and one Common Share purchase

Each whole warrant entitles the holder to acquire one Common Share of the Company at a price of C$0.60 per Common Share

for a period of five years.

Pursuant to the offering, certain directors and officers of the Company acquired 626,580 Units.

issuance of such Units in connection with the offering was considered a “related party transaction”

as such term is

defined under Multilateral Instrument 61-101 –

Protection of Minority Security Holders in Special Transactions (“MI

61-101”).

Resources and Exploration

with the digitization work, and since March 2020, the Company has been working systematically to bring a number of mineralized

zones into accordance with National Instrument 43-101 –

Standards of Disclosure for Mineral Projects (“NI 43-101”)

through drilling and channel sampling of the open stopes.

This work focused upon the mineralization that is closest to the existing

infrastructure and above the current water-level.

March 19, 2021, the Company announced an updated mineral resources estimate consisting of a total of 4.4 million tons in the Indicated

category, containing 3.0 million ounces of silver, 487 million pounds of zinc, and 176 million pounds of lead;

and a total of

5.6 million tons in the Inferred category, containing 8.3 million ounces of silver, 548 million pounds of zinc, and 312 million

pounds of lead.

May 3, 2021, the Company filed a technical report entitled “Technical Report for the Bunker Hill Mine, Coeur d’Alene

Mining District, Shoshone County, Idaho, USA”

with an effective date of March 22, 2021 prepared in accordance with NI 43-101

in support of such mineral resources estimate.

Further details regarding the Company’s mineral resources estimate, including

estimation methodologies, can be found in the technical report filed on EDGAR and SEDAR.

should be noted that mineral resources as stated above, including those delineated in the Inferred, Measured and Indicated categories,

are not mineral reserves as defined by SEC guidelines, and do now show demonstrated economic viability.

Due to the uncertainty

that may be attached to Inferred mineral resources, it cannot be assumed that all or any part of an Inferred mineral resource

will be upgraded to an Indicated or Measured mineral resource as a result of continued exploration.

Company currently anticipates that its 2021 drilling program will comprise approximately 32,000 feet to 39,000 feet of drilling

Silver-Focused

the completion of exploration drilling related to the updated mineral resources estimate as announced on March 19, 2021 (as described

above), the Company’s exploration strategy has been focused on high-grade silver targets within the upper areas of the Mine

that have been identified by the data review and digitization process.

The aim of this program is to identify, develop and add

high-grade silver resources in ways that materially increase the relative quantity of silver resources relative to lead and zinc.

with that strategy and concurrent with the announcement of the updated mineral resources estimate, the Company announced the identification

of a new silver exploration opportunity in the hanging wall of the Cate Fault which it intends to include in its ongoing drilling

In conjunction with this drilling campaign, continued digitization, geologic modeling and interpretation will continue

to focus on identifying additional high grade silver exploration targets.

March 29, 2021, the Company announced multiple high-grade silver mineralization results through chip-channel sampling of newly

accessible areas of the Mine identified through the Company’s proprietary 3D digitization program, and as part of its ongoing

silver-focused drilling program.

An area was identified on the 9-level that resulted in ten separate chip samples greater than

900 g/t AgEq (1) , each with minimum 0.6m length.

Mineralization remains open up dip, down dip and along strike from

the sampling location.

The Company also reported drill results including a 3.8m intercept with a grade of 996.6 g/t AgEq (1) ,

intersected at the down-dip extension of the UTZ zone at the 5-level.

The Company will continue to report mineralized drill intercepts

concurrent with its ongoing exploration program that is currently envisaged to comprise 10,000 to 12,000 feet in 2021.

used to calculate Ag Eq are as follows:

and Ag=$20/oz.

Management Optimization

EPA currently provides mine water treatment services for the Mine to ensure compliance with existing discharge standards.

is done via its management of the EPA’s Central Treatment Plant (“CTP”), located adjacent and downstream to

Although it also treats other contaminated water collected from other sources in the vicinity, with respect to its service

to the Mine, this facility treats all the water that exits the Kellogg Tunnel before it is discharged into the South Fork of the

Coeur D’Alene River.

September 2020, the Company began its water management program with the goal of improving the understanding of the Mine’s

water system and enacting immediate improvement in the water quality of effluent leaving the mine for treatment at the CTP.

by historical research provided by the EPA, the Company initiated a study of the water system of the mine to:

i) identify of the

areas where sulphuric acid (Acid Mine Drainage, or “AMD”) is generated in the greatest and most concentrated quantities,

and ii) understand the general flow paths of AMD on its way through and out of the mine as it travels to the CTP.

its improved understanding through this study, on February 11, 2021, the Company announced the successful commissioning of a water

pre-treatment plant located within the Mine, designed to significantly improve the quality of Mine water discharge, which in turn

would support a rapid re-start of the Mine.

Specifically, the water pre-treatment plant achieves this goal by reducing significantly

the amount of treatment required at the CTP, and the associated costs, before the Mine water is discharged into the south fork

of the Coeur D’Alene River, removing over 70% of the metals from water before it leaves the Mine, with the potential for

further improvements.

an effort to improve transparency to all stakeholders with regard to the results of this system, the Company launched a water

quality tracking platform on its website on March 15, 2021, which uploads real-time data every five minutes and provides an interactive

database to allow detailed historical analysis.

Infrastructure

Mine main level is termed the nine level and is the largest level in the Mine.

It is connected to the surface by the approximately

12,000 foot-long Kellogg Tunnel.

Three major inclined shafts with associated hoists and hoistrooms are located on the nine level.

These are the No.

1 shaft, which is used for primary muck hoisting in the main part of the Mine;

2 shaft, which is a primary

shaft for men and materials in the main part of the Mine;

3 Shaft, which is used for personnel, materials and muck

hoisting for development in the northwest part of the Mine.

top stations of these shafts and the associated hoistrooms and equipment have all been examined by Company personnel and are in

moderately good condition.

The Company believes that all three shafts remain in a condition that they are repairable and can be

bought back into good working order over the next few years.

water level in the Mine is held at approximately the ten level of the Mine, roughly 200 feet below the nine level.

historically developed to the 27 level, although the 25 level was the last major level that underwent significant development

and past mining.

Each level is approximately 200 feet vertically apart.

southeastern part of the Mine was historically serviced by the Cherry Raise, which consisted of a two-compartment shaft with double

drum hoisting capability that ran at an incline up from the nine level to the four level.

The central part of the Mine was serviced

upward by the Last Chance Shaft from the nine level to the historic three or four level.

Neither the Cherry Raise or the Last

Chance shaft are serviceable at this time.

However, the upper part of the Mine from eight level up to the four level has been

developed by past operators by a thorough-going rubber tire ramp system, which is judged to be about 65% complete.

Company has repaired the first several thousand feet of the Russell Tunnel, which is a large rubber-tire capable tunnel with an

entry point at the head of Milo Gulch.

This tunnel will provide early access to the UTZ Zone, and Quill and Newgard Zones, following

ramp and access development.

The Company has made development plans to provide interconnectivity of the ramp system from the Russell

Tunnel at the four level down to the eight level, with further plans to extend the ramp down to the nine level.

Thus rubber-tired

equipment will be used for mining and haulage throughout the upper Mine mineral zones, which have already been identified, and

for newly found zones.

Kellogg Tunnel will be used as a tracked rail haulage tunnel for supply of personnel and materials into the Mine and for haulage

of mined material out of the Mine.

Historically, the Kellogg Tunnel was used in this manner when the Mine was producing upwards

of 3,000 tons per day of mined material.

The Company has inspected the Kellogg Tunnel for its entire length and has determined

that significant timbered sections of the tunnel will need extensive repairs.

These are areas that intersect various faults passing

through the Kellogg Tunnel at normal to oblique angles and create unstable ground.

Company has determined that all of the track, as well as spikes, plates and ties holding the track will need to be replaced, and

has started that process in support of the on-going exploration program.

Additionally, the water ditch that runs parallel to the

track will need to be thoroughly cleaned out and new timber supports and boards that keep the water contained in its path will

need to be installed.

All new water lines, compressed air lines and electric power feeds will also need to be installed.

cost estimate for this Kellogg Tunnel work is still in process as of the date hereof, but the time estimate for these repairs

is approximately twelve months.

Hill Mine Re-start Developments and Preliminary Economic Assessment

November 2020, the Company launched a Preliminary Economic Assessment (“PEA”) to assess the potential for a rapid

re-start of the Mine for minimal capital by focusing on the de-watered upper areas of the Mine, utilizing existing infrastructure,

and based on truck haulage and toll milling methods.

support the Company’s strategy of targeting a rapid production re-start as outlined above, development drilling subsequent

to November 2020 focused on targets in the upper levels of the Mine located in close proximity to existing infrastructure, aimed

at expanding the resource base for the PEA.

January 2021, the Company reported continued progress towards completing a PEA and further detailed the potential parameters of

the re-start, including:

i) low up-front capital costs through utilization of existing infrastructure, potentially enabling a

rapid production re-start;

ii) a staged approach to mining, potentially supporting a long-life operation;

iii) underground processing

and tailings deposition with potential for high recovery rates;

iv) development of a sustainable operation with minimal environmental

and v) potential increase in the existing resource base.

April 20, 2021, the Company reported the results of its PEA for the Mine.

The PEA contemplates a $42 million initial capital cost

(including 20% contingency) to rapidly restart the Mine, generating approximately $20 million of annual average free cash flow

over a 10-year mine life, and producing over 550 million pounds of zinc, 290 million pounds of lead, and 7 million ounces of silver

at all-in sustaining costs of $0.65 per payable pound of zinc (net of by-products).

The PEA contemplates a low environmental footprint,

long-term water management solution, and significant positive economic impact for the Shoshone County, Idaho community.

is based on the mineral resources estimate described above and published on March 22, 2021, following the drilling program conducted

in 2020 and early 2021 to validate the historical reserves.

The PEA includes a mining inventory of 5.5Mt, which represents a portion

of the 4.4Mt Indicated mineral resource and 5.6Mt Inferred mineral resource.

Further details regarding the PEA can be found in

the news release dated April 20, 2021 on EDGAR, SEDAR and the Company’s website www.bunkerhillmining.com.

PEA is preliminary in nature and includes Inferred mineral resources that are considered too speculative geologically to have

the economic considerations applied to them that would enable them to be categorized as mineral reserves.

There is no certainty

that the project described in the PEA will be realized.

Mineral resources that are not mineral reserves do not have demonstrated

economic viability.

April 27, 2021, the Company announced that it had engaged Cutfield Freeman & Co.

to provide independent advice on all aspects

of restart mining finance related to the Mine.

should be noted that mineral resources as stated above, including those delineated in the Inferred, Measured and Indicated categories,

are not mineral reserves as defined by SEC guidelines, and do now show demonstrated economic viability.

Due to the uncertainty

that may be attached to Inferred mineral resources, it cannot be assumed that all or any part of an Inferred mineral resource

will be upgraded to an Indicated or Measured mineral resource as a result of continued exploration.

of Operations

following discussion and analysis provides information that the Company believes is relevant to an assessment and understanding

of its results of operation and financial condition for the three months ended March 31, 2021 as compared to the three months

ended March 31, 2020.

Unless otherwise stated, all figures herein are expressed in U.S.

dollars, which is the functional currency

of the Company.

of the three months ended March 31, 2021 and March 31, 2020

the three months ended March 31, 2021 and March 31, 2020, the Company generated no revenue.

the three months ended March 31, 2021, the Company reported total operating expenses of $4,623,974 as compared to $1,362,960 during

the three months ended March 31, 2020, an increase of $3,261,014 or approximately 239%.

increase in total operating expenses was primarily due to an increase in exploration expense of $2,172,561 ($3,088,302 in the

three months ended March 31, 2021 compared to $915,741 in the three months ended March 31, 2020) due to increased exploration

activities aimed at expanding the resource base for the PEA.

Increases in operating and administration ($837,945 in the three

months ended March 31, 2021 compared to $183,724 in the three months ended March 31, 2020), legal and accounting ($219,108 in

the three months ended March 31, 2021 compared to $62,408 in the three months ended March 31, 2020), and consulting ($478,619

in the three months ended March 31, 2021 compared to $201,087 in the three months ended March 31, 2020) were due to increased

corporate activities, including professional and consulting expense related to the most recent financing and support for completion

financial accounting purposes, the Company reports all direct exploration expenses under the exploration expense line item of

the Condensed Interim Consolidated Statements of Income and Comprehensive Income.

Certain indirect expenses may be reported as

operation and administration expense or consulting expense on the statement of operations.

Net Incomes and Comprehensive Income

Company reported net income and comprehensive income of $5,837,809 for the three months ended March 31, 2021, compared to net

income and comprehensive income of $9,301,597 for the three months ended March 31, 2020, a decrease of $3,463,788 or approximately

The decrease in net income and comprehensive income was primarily due to an increase in operating expenses and a lower gain

related to the valuation of derivative liabilities in the three months ended March 31, 2021, relative to the three months ended

March 31, 2020.

Company reported a gain related to the change in derivative liability of $10,475,376 in the three months ended March 31, 2021,

as compared to a gain of $10,845,404 in the three months ended March 31, 2020.

The gains in each three-month period related to

a decrease in the fair value of the Company’s outstanding warrants due to a significant decrease in the Company’s

The Company’s share price decreased from C$0.52 on December 31, 2020 to C$0.35 on March 31, 2021.

OF FINANCIAL CONDITION

and Capital Resources

Company does not have sufficient working capital needed to meet its current fiscal obligations and commitments, including commitments

associated with the acquisition of the Mine.

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.

Management is considering various financing alternatives including, but not limited

to, raising capital through the capital markets and debt financing.

noted previously, the Company has engaged Cutfield Freeman & Co.

to provide independent advice on all aspects of restart mining

finance related to the Mine, including the acquisition of the Mine.

Company is also working to secure adequate capital to continue making lease payments, payments to the EPA, conduct exploration

activities on site and cover general and administrative expenses associated with managing a public company.

February 2021, the Company closed a non-brokered private placement of 19,994,080 units of the Company at C$0.40 per unit for gross

proceeds of C$7,997,632.

Each unit consists of one Common Share of the Company and one Common Share purchase warrant, which entitles

the holder to acquire one Common Share at a price of C$0.60 per Common Share for a period of five years.

In connection with the

financing, the Company paid a cash commission of C$140,400 and issued 351,000 finder options, which are exercisable into units

at an exercise price of C$0.40 for a period of three years.

Pursuant to the offering, certain directors and officers of the Company

acquired 626,580 Units.

This issuance of such Units in connection with the offering was considered a “related party transaction”

as such term is defined under MI 61-101.

Company has accounted for the warrants issued through units issuance in accordance with ASC Topic 815.

These warrants issued through

units issuance are considered derivative instruments as they were issued in a currency other than the Company’s functional

currency of the U.S.

The estimated fair value of warrants accounted for as liabilities was determined on the date of issue

and marks to market at each financial reporting period.

The change in fair value of the warrant liability is recorded in the interim

condensed consolidated statements of income and comprehensive income as a gain or loss and is estimated using the Binomial model.

Company’s operations could be significantly adversely affected by the effects of a widespread global outbreak of a contagious

disease, including the current outbreak of respiratory illness caused by 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.

Assets and Total Assets

of March 31, 2021, the Company’s balance sheet reflects that the Company had:

i) total current assets of $6,012,261, compared

to total current assets of $4,045,618 at December 31, 2020, an increase of $1,966,643 or approximately 49%;

and ii) total assets

of $8,619,234, compared to total assets of $6,709,016 at December 31, 2020, an increase of $1,910,218 or approximately 28%.

increase in current assets was impacted by the increase in cash and cash equivalents, primarily due to proceeds from the non-brokered

private placement which closed on February 24, 2021.

Current Liabilities and Liabilities

of March 31, 2021, the Company’s balance sheet reflects that the Company had total current liabilities of $13,939,595 and

total liabilities of $31,315,245, compared to total current liabilities of $14,178,553 and total liabilities of $38,246,613 as

of December 31, 2020.

The decrease in total liabilities is reflective of a decrease in derivative warrant liability as a result

of a decrease in the Company’s share price.

of March 31, 2021, the Company had negative working capital of $7,927,334 compared to negative working capital of $10,132,935

as of December 31, 2020.

The decrease in negative working capital is due the increase in cash and cash equivalents primarily related

to the proceeds of the non-brokered private placement in February 2021, noted previously.

the three months ended March 31, 2021, cash was primarily used to fund activities at the Mine operations.

The Company reported

a net increase in cash of $1,944,737 during the three months ended March 31, 2021 as a result of net proceeds of $6,008,672 from

the non-brokered private placement which closed on February 24, 2021, offset by cash flows of $4,031,935 used in operating and

financing activities.

unaudited interim condensed consolidated financial statement filings have been prepared on the going concern basis, which assumes

that adequate sources of financing will be obtained as required and that the Company’s assets will be realized, and liabilities

settled in due course of business.

Accordingly, the interim condensed consolidated unaudited financial statements do not include

any adjustments related to the recoverability of assets and classification of assets and liabilities that might be necessary should

the Company not be able to continue as a going concern.

The going concern assumption is discussed in the financial statements

Note 1 –

Nature and Continuance of Operations and Going Concern .

ACCOUNTING ESTIMATES

The preparation of the interim condensed

consolidated financial statements in conformity with U.S, GAAP requires management to make estimates and assumptions that affect

the reported amounts of assets, liabilities and contingent liabilities at the date of the financial statements and reported amounts

of expenses during the reporting period.

Estimates and judgments are continuously evaluated and are based on management’s

experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

Actual outcomes can differ from these estimates.

The key sources of estimation uncertainty that have a significant risk of causing

material adjustment to the amounts recognized in the financial statements are:

Share-based payments

Management determines costs for share-based

payments using market-based valuation techniques.

The fair value of the share awards and warrant liabilities are determined at

the date of grant using generally accepted valuation techniques and for warrant liabilities at each balance sheet date thereafter.

Assumptions are made and judgment used in applying valuation techniques.

These assumptions and judgments include estimating the

future volatility of the stock price and expected dividend yield.

Such judgments and assumptions are inherently uncertain.

in these assumptions affect the fair value estimates.

Sheet Arrangements

Company has no off-balance sheet arrangements.
