Vancouver, May 29, 2024 - Blackrock Silver Corp. (TSXV: BRC) ("Blackrock" or the "Company") is pleased to announce that it has completed its previously announced "bought deal" public offering of 32,343,750 units of the Company (the "Units") at a price of $0.32 per Unit for aggregate gross proceeds to the Company of $10,350,000 (the "Offering"). The completed Offering includes the full exercise of the over-allotment option by the Underwriters (as defined herein) for the sale of 4,218,750 Units for proceeds of $1,350,000. Eric Sprott, through 2176423 Ontario Ltd, a corporation beneficially owned by him, participated in the Offering with a lead order of $4,000,000.

Each Unit consists of one common share of the Company (a "Common Share") and one-half of one Common Share purchase warrant of the Company (each whole warrant, a "Warrant").

Andrew Pollard, President & Chief Executive Officer of Blackrock, commented: "With a significant lead order from Eric Sprott, and the participation of a number of new as well as existing shareholders, proceeds from this Offering will see the drills return to Tonopah West this summer for our much anticipated resource conversion and expansion program. Roughly 20,000 metres (m) of drilling (8,000m of reverse circulation and 12,000m of core) is planned to convert inferred resources to M&I (measured & indicated) on our Merten and Bermuda veins that run along the southern edge of our DPB deposit. The program will crystalize further expansion potential across the 1km vein corridor in an effort to bridge the gap between the DPB and NW Step-out areas."

The net proceeds from the Offering will be used for exploration, resource expansion and conversion drilling, working capital and general corporate purposes.

The Offering was completed pursuant to an underwriting agreement dated May 23, 2024 entered into among the Company and a syndicate of underwriters led by Research Capital Corporation as the lead underwriter and sole bookrunner, on behalf of a syndicate of underwriters, including Canaccord Genuity Corp., Red Cloud Securities Inc. and Ventum Financial Corp.

The Offering remains subject to the final approval of the TSX Venture Exchange (the "TSX-V").
