Blackrock Silver Enters into Option Agreement with Tearlach Resources to Develop the Tonopah North Lithium Project

Vancouver, January 10, 2023 - Blackrock Silver Corp. (TSXV: BRC) (the "Company" or "Blackrock") is pleased to announce that its wholly-owned Nevada subsidiary, Blackrock Gold Corp. ("Blackrock Gold") has entered into an option agreement (the "Option Agreement") with Tearlach Resources Ltd. (TSXV: TEA) and its wholly-owned Nevada subsidiary, Pan Am Lithium (Nevada) Corp. (collectively, "Tearlach") pursuant to which Tearlach has been granted the option to acquire, in two stages, up to a 70% interest in the lithium minerals in certain unpatented mining claims forming a portion of the Company's Tonopah North project (the "Tonopah North Project") in Esmeralda County and Nye County, Nevada, upon incurring cumulative exploration expenditures of US$15,000,000 and the completion of a Feasibility study within 5 years. Information concerning the discovery of lithium during the Company's first exploration drill program on the Tonopah North Project was announced in the Company's news release dated October 25, 2022.

Andrew Pollard, President and Chief Executive Officer of Blackrock, commented: "This deal creates significant value for Blackrock shareholders by pairing our emerging lithium discovery with a world-class lithium technical team while retaining shareholder upside in potential new silver and gold discoveries on our underexplored Tonopah North project. Tearlach has an impressive team with recognized expertise specifically relating to lithium claystone deposits, and has proposed an aggressive exploration plan that will see up to US$15,000,000 spent as the project is quickly drilled and advanced towards development studies. This transaction allows Blackrock shareholders to gain an interest in an active lithium project while allowing the Company to focus its resources on our high-grade precious metal discoveries. With one of the highest-grade undeveloped silver-gold resources in the world at the adjacent Tonopah West¹ project, a new bonanza gold & silver discovery at Silver Cloud, and this transaction, which provides for advancement of our lithium interests, Blackrock is poised for significant growth across our entire project portfolio, and is emerging as a player within the domestic green energy metals space."

Morgan Lekstrom, Chief Executive Officer of Tearlach, commented, "With initial mapping completed and a world-class-Nevada based team with significant geological and processing experience in lithium-bearing clays, we have a roadmap to accelerate and aggressively drill. We plan to drill a much larger core program and advance to the resource estimate while concurrently running engineering and process models."

Option Agreement

Under the terms of the Option Agreement, Tearlach has the right to explore for, and the exclusive option (the "First Option") to earn a 51% interest in, the lithium minerals from the topographical surface to 650 feet below the surface of a portion of the Tonopah North Project (the "Optioned Zone") by incurring expenditures for exploration and development work on the Tonopah North Project ("Expenditures") in the aggregative amount of at least US$5,000,000 consisting of: (i) at least US$500,000 in Expenditures on or before January 9, 2024; and (ii) at least US$4,500,000 in Expenditures on or before January 9, 2026 (collectively, the "Initial Earn-In").

Subject to Tearlach completing the Initial Earn-In, under the terms of the Option Agreement, Tearlach shall have the option (the "Second Option") to elect within thirty (30) days of completing the Initial Earn-In to earn an additional 19% interest in lithium minerals in the Optioned Zone for an aggregate interest of 70% by: (i) expending an additional US$10,000,000 in Expenditures; and (ii) by bearing the costs of preparation of a National Instrument 43-101 compliant bankable feasibility study for the development and construction of a lithium mine on the Tonopah North Project (collectively, the "Additional Earn-In"), with such Second Option terminating if not exercised by Tearlach by January 9, 2028.

In addition, pursuant to the Option Agreement, Tearlach has agreed to pay the Company the sum of US$100,000 in cash on or before April 30, 2024, failing which the Company shall have the right to terminate the Option Agreement.

The exploration and development rights conferred to Tearlach under the Option Agreement in respect of the Tonopah North Project are exclusive to lithium minerals in the Optioned Zone. Subject to the terms of the Option Agreement, Blackrock retains and reserves the rights to explore for, develop and mine all minerals (including gold and silver) other than lithium on the entire Tonopah North Project, including the Optioned Zone.

Joint Venture

Upon Tearlach completing the Initial Earn-In and exercising the First Option, Tearlach and Blackrock Gold shall enter into a definitive mining joint venture agreement (the "Joint Venture Agreement") in respect of the management and ownership of the Optioned Zone of the Tonopah North Project (the "Joint Venture"). After completion of the Additional Earn-In, Tearlach may elect to exercise the Second Option, upon which its participation interest in the Joint Venture shall increase by an additional 19% to a total of 70%. The parties to the Joint Venture shall contribute to future Expenditures in accordance with their respective participating interests as prescribed in the Joint Venture Agreement.

Pursuant to the Joint Venture Agreement, if at any time a party's participating interest in the Joint Venture is diluted to below 5%, the diluted party shall be deemed to have withdrawn from the Joint Venture and its participating interest in the Joint Venture shall be converted to a non-administrative, non-executive and non-working mineral production royalty of two percent 2.0% of the gross revenues from the sale of lithium minerals and lithium mineral products produced from the Tonopah North Project.

Subject to the terms of the Joint Venture Agreement, Tearlach shall be the initial manager of the Joint Venture and shall have control of the activities and operations of the Joint Venture.
