Blackrock Silver Announces Upsize to Previously Announced Bought Deal Financing to $3.7 Million

Vancouver, January 17, 2024 - Blackrock Silver Corp. (TSXV: BRC) (the "Company" or "Blackrock") is pleased to announce that due to significant investor demand, the Company has upsized its previously announced "bought deal" public offering (the "Offering") to C$3,700,000. Under the upsized Offering, the Underwriters (as defined herein) have agreed to purchase for resale 18,500,000 units of the Company (each, a "Unit") at a price of C$0.20 per Unit (the "Offering Price"). Red Cloud Securities Inc. is acting as lead underwriter and sole bookrunner on behalf of a syndicate of underwriters (collectively, the "Underwriters").

Each Unit will consist of one common share of the Company (each, a "Common Share") and one half of one Common Share purchase warrant (each whole warrant, a "Warrant"). Each whole Warrant shall entitle the holder to purchase one Common Share of the Company at a price of C$0.30 at any time on or before that date which is 36 months after the closing date of the Offering.

The Company has granted to the Underwriters an option exercisable at the Offering Price for a period of 30 days after and including the closing date of the Offering, to purchase for resale up to an additional 15% of the number of Units sold under the Offering to cover over allotments, if any, and for market stabilization purposes. The Offering is expected to close on or about January 26, 2024 (the "Closing Date") and is subject to certain conditions including, but not limited to, the receipt of all necessary regulatory approvals, including the approval of the TSX Venture Exchange.

The net proceeds raised under the Offering will be used by the Company to complete the final option payment on the Company's flagship Tonopah West project ("Tonopah West") in Nevada, after which the Company will own 100% of Tonopah West, continue with metallurgical characterization, engineering evaluation, and hydrological assessment, as well as for general working capital and corporate purposes.

The Units will be sold by way of a prospectus supplement to be filed in all of the provinces of Canada except Québec to supplement the short form base shelf prospectus of the Company dated August 4, 2023. The Units may also be sold in the United States on a private placement basis pursuant to one or more exemptions from the registration requirements of the United States Securities Act of 1933, as amended (the "U.S. Securities Act") and in such other jurisdictions outside of Canada and the United States, in each case in accordance with all applicable laws provided that no prospectus, registration statement or similar document is required to be filed in such jurisdiction.

The securities being offered pursuant to the Offering have not been, nor will they be, registered under the U.S. Securities Act or any U.S. state securities laws, and may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons absent registration or an applicable exemption from the registration requirements.

This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
