Blackrock Announces C$6 Million Private Placement, Led by a C$2 Million Investment from First Majestic Silver

Vancouver, October 20, 2021 - Blackrock Silver Corp. (TSXV: BRC) (the "Company") is pleased to announce a non-brokered private placement (the "Offering") of 7,500,000 units (the "Units") at a price of C$0.80 per Unit for gross proceeds of C$6,000,000. The Company is pleased to advise that First Majestic Silver Corp. has agreed to purchase C$2 million of the Offering. Each Unit will be comprised of one common share and one-half of one share purchase warrant. Each whole warrant will entitle the holder to acquire one additional common share in the capital of the Company at a price of C$1.20 for a period of two years from the date the Units are issued.

The Offering is scheduled to close on or about October 29, 2021, and is subject to certain conditions including, but not limited to, the receipt of all necessary approvals including the approval of the TSX Venture Exchange. The Units to be issued under the Offering will have a hold period of four months and one day from the closing. The net proceeds of the Offering will be used by the Company for expansion drilling at Tonopah West and for scout drilling at Tonopah North, in addition to general working capital.

Andrew Pollard, Blackrock President & CEO, commented, "We're very happy to see First Majestic increase their equity position in Blackrock. These funds will be used to daylight additional blue sky at the project, both in terms of expansion drilling at DPB, and for scout exploration on our new Tonopah North claims. With 24 drillholes pending, our resource definition program nearing completion, and our geologic model demonstrating significant expansion potential, we're very excited to have the funds to allow us to continue to aggressively prove up this discovery while we await delivery of our maiden resource estimate."

The Company may pay finder's fees on a portion of the Offering of up to 6% in cash and, for those applicable, finder's warrants equal to 3% of such Units placed by the finder, each finder's warrant exercisable for one common share for a 2 year term at a price of $1.20. The finder's fees shall be paid in accordance with applicable securities laws and the policies of the TSX Venture Exchange.

It is anticipated that certain directors, officers and other insiders of the Company may acquire Units under the Offering. Such participation will be considered to be "related party transactions" within the meaning of TSX Venture Exchange Policy 5.9 (the "Policy") and Multilateral Instrument 61-101-Protection of Minority Security Holders in Special Transactions ("MI 61-101") adopted in the Policy. The Company intends to rely on the exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101 in respect of related party participation in the Offering as neither the fair market value (as determined under MI 61-101) of the subject matter of, nor the fair market value of the consideration for, the transaction, insofar as it involves interested parties, is expected to exceed 25% of the Company's market capitalization (as determined under MI 61-101).

The securities offered have not been, and will not be, registered under the U.S. Securities Act of 1933, as amended (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, United States persons absent registration or any applicable exemption from the registration requirements of the U.S. Securities Act and applicable U.S. state securities laws. This news release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
