Bunker Hill Mining Corp.

82 Richmond Street East

Toronto, ON M5C 1P1

Dear Sirs/Mesdames:

Echelon Wealth Partners Inc. (“Echelon”) and Roth Capital Partners, LLC (“Roth” and together with Echelon, the “Lead Agents”), as co-lead agents and joint bookrunners, and Laurentian Bank Securities Inc. (together with the Lead Agents, the “Agents”) understand that Bunker Hill Mining Corp. (the “Corporation”) proposes to issue and sell, in one or more tranches: (i) special warrants of the Corporation (the “Initial Special Warrants”) at a price of $0.12 per Initial Special Warrant (the “Issue Price”); and (ii) units of the Corporation (the “Private Placement Units”) at the Issue Price, on a commercially reasonable, “best efforts” private placement basis for aggregate gross proceeds of up to $9,000,000 (the “Offering”).

Each Private Placement Unit will consist of one share of common stock of the Corporation (each a “PP Unit Share”) and one common share purchase warrant of the Corporation (each a “PP Warrant”). Each PP Warrant will entitle the holder thereof to acquire one share of common stock of the Corporation (a “PP Warrant Share”) at an exercise price of $0.15 per PP Warrant Share, until the date which is thirty-six (36) months following the applicable Closing Date, subject to adjustment in certain events. The PP Warrants will also be exercisable on a cashless basis in the event the Registration Statement (as hereinafter defined) is not effective on the date of exercise of such Warrants. The PP Warrants will be governed by PP Warrant certificates (collectively, the “PP Warrant Certificates”) to be issued by the Corporation in form and substance satisfactory to the Corporation and Echelon. The description of the PP Warrants herein is a summary only and is subject to the specific attributes and detailed provisions of the PP Warrant Certificate. In the case of any inconsistency between the description of the PP Warrants in this Agreement and their terms and conditions as set forth in the PP Warrant Certificate, the provisions of the PP Warrant Certificate will govern.

In addition, the Corporation hereby grants the Agents an option (the “Agents’ Option”), exercisable in whole or in part, to arrange for the sale of up to such additional number of special warrants only (and for greater certainty, not an additional number of Private Placement Units) as is equal to 15% of the aggregate amount of Initial Special Warrants and Private Placement Units, being up to 11,250,000 special warrants (the “Additional Special Warrants”, and, together with the Initial Special Warrants, the “Special Warrants”), at the Issue Price per Additional Special Warrant. The Agents’ Option is exercisable at any time up to 48 hours prior to the final Closing Date (as hereinafter defined).

The Special Warrants will be duly and validly created and issued pursuant to, and governed by, a special warrant indenture (the “Special Warrant Indenture”) to be entered into effective on the date hereof between the Corporation and Capital Transfer Agency ULC (or such other agent determined by the Corporation and the Lead Agents), as special warrant agent in respect of the Special Warrants (the “Special Warrant Agent”). Each Special Warrant shall be automatically exercisable (without payment of any further consideration and subject to customary anti-dilution adjustments) into one unit of the Corporation (a “Unit”) on the date (the “Automatic Exercise Date”) that is the earlier of: (i) the date that is three (3) Business Days following the date on which the Corporation has obtained notification that the Registration Statement (as hereinafter defined) of the Corporation filed with the SEC (as hereinafter defined) has been declared effective by the SEC (the “Qualification Event”); and (ii) the date that is six months following the applicable Closing Date. The description of the Special Warrants herein is a summary only and is subject to the specific attributes and detailed provisions of the Special Warrants to be set forth in the Special Warrant Indenture. In the case of any inconsistency between the description of the Special Warrants in this Agreement and their terms and conditions as set forth in the Special Warrant Indenture, the provisions of the Special Warrant Indenture will govern.

Each Unit will consist of one share of common stock of the Corporation (each a “Unit Share”) and one common share purchase warrant of the Corporation (each a “Warrant”). Each Warrant will entitle the holder thereof to acquire one share of common stock of the Corporation (a “Warrant Share”) at an exercise price of $0.15 per Warrant Share, until the date which is thirty-six (36) months following the applicable Closing Date, subject to adjustment in certain events. The Warrants will also be exercisable on a cashless basis in the event the Registration Statement is not effective on the date of exercise of such Warrants. The Warrants shall be duly and validly created and issued by the Corporation pursuant to, and governed by, the terms of a warrant indenture (the “Warrant Indenture”) to be entered into on the date hereof between the Corporation and Capital Transfer Agency ULC (or such other agent determined by the Corporation and the Lead Agents), in its capacity as warrant agent in respect of the Warrants (the “Warrant Agent”). The description of the Warrants herein is a summary only and is subject to the specific attributes and detailed provisions of the Warrants to be set forth in the Warrant Indenture. In the case of any inconsistency between the description of the Warrants in this Agreement and their terms and conditions as set forth in the Warrant Indenture, the provisions of the Warrant Indenture will govern.

The Corporation will use its commercially reasonable efforts to complete the Qualification Event on or before the date that is six (6) months following the Initial Closing Date; provided, however, that there is no assurance that a Qualification Event will be completed. In the event that the Qualification Event has not been completed on or before four months following the Initial Closing Date, each unexercised Special Warrant will thereafter entitle the holder to receive, upon the exercise thereof, at no additional cost, a penalty unit (each, a “Penalty Unit”) per Special Warrant. Each Penalty Unit will consist of 1.2 shares of common stock of the Corporation and 1.2 common share purchase warrants of the Corporation.

Upon and subject to the terms and conditions set forth herein, the Agents hereby agree to act, and upon acceptance hereof, the Corporation hereby appoints the Agents, as the Corporation’s exclusive agents, to offer for sale by way of private placement on a commercially reasonable “best efforts” agency basis, without underwriter liability, the Special Warrants and the Private Placement Units to be issued and sold pursuant to the Offering and the Agents agree to arrange for purchasers of the Special Warrants and the Private Placement Units in the Designated Jurisdictions (as hereinafter defined) and in those jurisdictions outside Canada where the Special Warrants and the Private Placement Units may lawfully be sold pursuant to the terms and conditions hereof.

In consideration of the services to be rendered by the Agents hereunder, on the applicable Closing Date, the Agents will receive a cash commission fee (the “Agents’ Commission”) equal to 6.0% of the aggregate gross proceeds of the Offering in such applicable Closing. As additional consideration for their services, the Agents shall receive from the Corporation on the applicable Closing Date that number of compensation options (the “Agents Compensation Options”), registered in such manner as directed by the Agents, exercisable to purchase that number of Units (each a “Compensation Unit”), as is equal to 6.0% of the aggregate number of Special Warrants and Private Placement Units issued pursuant to the Offering on such Closing Date. Each Agents Compensation Option will entitle the holder to acquire one Compensation Unit at the Issue Price until the date that is thirty-six (36) months following the applicable Closing Date. Each Compensation Unit will be comprised of one Agents’ Commission Share (as hereinafter defined) and one Agents’ Commission Warrant (as hereinafter defined). Each whole Agents’ Commission Warrant will entitle the holder thereof to acquire one Agents’ Commission Warrant Share (as hereinafter defined) at an exercise price of $0.15, until the date that is thirty-six (36) months following the applicable Closing Date.

The Corporation shall be entitled to designate in writing a list of purchasers (the “President’s List”) who may purchase Special Warrants and/or Private Placement Units under the Offering. Notwithstanding the foregoing, the Agents’ Commission payable by the Corporation to the Agents for subscriptions received from the President’s List Purchasers shall be reduced to 3.0% of the aggregate gross proceeds from President’s List Purchasers and the number of Agents Compensation Options shall be reduced to 3.0% of the number of Special Warrants and Private Placement Units sold to the President’s List Purchasers.

Additionally, the Corporation shall be entitled to sell Special Warrants to Valuestone Global Resources Fund I LP (or an affiliate of), management, the board of directors or insiders of the Corporation (the “Company Purchasers”).

The parties acknowledge that the Special Warrants and the Private Placement Units have not been and will not be registered under the U.S. Securities Act (as hereinafter defined) or the securities laws of any state of the United States and may not be offered or sold in the United States, or to or for the account or benefit of, U.S. Persons (as hereinafter defined), except pursuant to exemptions from the registration requirements of the U.S. Securities Act and the applicable laws of any state of the United States in the manner specified in this Agreement and pursuant to the representations, warranties, acknowledgments, agreements and covenants of the Corporation and the Agents and the U.S. Affiliates (as hereinafter defined) contained hereto. The Corporation has agreed that it will use commercially reasonable efforts to file the Registration Statement in order to register the Registrable Securities (as hereinafter defined) for the benefit of the Purchasers and the Agents. All actions to be undertaken by the Agents in the United States or to, or for the account or benefit of, U.S. Persons in connection with the matters contemplated herein shall be undertaken through a U.S. Affiliate.
