Substantial Savings On Payments And Reduction of Work Obligations Realized

Vancouver, British Columbia--(Newsfile Corp. - October 27, 2023) - Blackrock Silver Corp. (TSXV: BRC) (the "Company" or "Blackrock") is please to announce that the Company has entered into a further amendment (the "Amendment") to the mineral lease agreement between the Company and Pescio Exploration, LLC (the "Owner") dated October 27, 2017, as amended June 1, 2019 (the "Lease") which provides for the exploration, development, mining and option to purchase of the Silver Cloud project situated in Elko County, Nevada ("Silver Cloud").

Pursuant to the terms of the Amendment:

(i) the annual cash payments required by the Company to maintain the Lease in good standing have been reduced and amended as follows:

(ii) the Company shall have the right, exercisable any time within 10 years of the date of the Amendment, to buy down the 3.5% royalty payable to the Owner to 2% by way of cash payment to the Owner of US$4.5 million;

(iii) in substitution of the previous drilling commitment on Silver Cloud provided for in the Lease, the Company is now required to incur work expenditures on Silver Cloud in a minimum amount of: (A) US$500,000 on or before October 27, 2030; and (B) a further US$500,000 on or before October 27, 2033, representing a cumulative total work commitment of $1,000,000;

(iv) the Company's option to purchase 100% of Silver Cloud (the "Purchase Option") has been amended to provide for a purchase price of: (A) US$5,000,000 if the Purchase Option is exercised on or before October 27, 2029; and (B) US$7,000,000 (subject to annual inflationary increases) if the Purchase Option is exercised after October 27, 2029; and

(v) the Company has agreed to pay to the Owner a one-time cash payment of US$75,000 in the event that the Company sells all or the majority of its interest in the mining claims comprising Silver Cloud or enters into or forms a joint venture on Silver Cloud wherein another party may earn an interest in at least fifty-percent (50%) of Silver Cloud.

Andrew Pollard, President and Chief Executive Officer of the Company, commented, "The restructuring of the underlying terms at Silver Cloud allow Blackrock to realize substantial savings, both immediate and over the long term, creating a compelling opportunity for our investors as we seek to see our early-staged bonanza grade discovery (see January 17, 2023 news release) advanced. With its large land package immediately adjacent to two of Nevada's highest-grade historic gold mines, Midas and Hollister, both of which are owned by Hecla, this deal makes us a stronger company over the coming years, while freeing up our treasury in the short term to be focused on the rapid advancement of our flagship Tonopah West project."
