Vancouver, British Columbia TheNewswire – October 20th, 2025 Prismo Metals Inc. (the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce a non-brokered private placement (the ‘ Private Placement ‘) of 12.5 million units of the Company (‘ Units ‘) at an issue price of $0.10 per Unit for minimum gross proceeds of $1,250,000. Each Unit will consist of one common share in the capital of the Company (a ‘ Share ‘) and one-half of one common share purchase warrant of the Company (each whole warrant, a ‘ Warrant ‘). Each Warrant will entitle the holder to purchase one Share for a period of thirty-six (36) months from the date of issue at an exercise price of $0.175. The Warrants will contain an accelerated expiry clause (the ‘ Acceleration Clause ‘). Pursuant to the Acceleration Clause, if the Shares of the Company close at or above $0.25 for ten (10) consecutive trading days on the Canadian Securities Exchange (‘ CSE ‘), then the Company may accelerate the expiry date of the Warrants by issuing a news release announcing the accelerated Warrant term, pursuant to which the Warrants will expire on the 30th calendar days after the date of such news release.

The Company intends to use the net proceeds of the Private Placement primarily for drilling at its Silver King project and for general corporate purposes . In August 2025, Prismo submitted a plan of operations for the drill program with the Forest Service in Arizona. The first phase of drilling at Silver King will consist of a minimum of 1,000 meters.

Dr. Craig Gibson, Chief Exploration Officer of Prismo commented: ‘This first phase is designed to test the upper half of the steeply dipping pipelike Silver King mineralized body as well as potentially mineralization adjacent to the dense stockwork that was the focus of historic mining. Follow up drilling will expand on the initial program based on the results and may include separate targets outside of the historic mining area, such as the polymetallic vein mentioned above. The discovery of the two mineralized veins and porphyry style mineralization has resulted in Prismo evaluating a larger drill program to test those targets.’

Dr. Gibson added: ‘We have also received the overlimit assays for silver for four samples from the Ripsey mine, which range from 132 to 224 g/t Ag. These results confirm the high-grade nature of the mineralization along the Ripsey vein, exposed at the surface and in underground workings over about 600 meters along strike.’

The Private Placement will also be made available to existing shareholders of the Company who, as of the close of business on October 18th, 2025, held Shares (and who continue to hold such Shares as of the closing date of the Private Placement), pursuant to the existing securityholder exemption set out in BC Instrument 45-534 – Exemption From Prospectus Requirement for Certain Trades to Existing Security Holders (the ‘ Existing Securityholder Exemption ‘). The Existing Securityholder Exemption limits a shareholder to a maximum investment of CAD$15,000 in a 12-month period unless the shareholder has obtained advice regarding the suitability of the investment and, if the shareholder is resident in a jurisdiction of Canada, that advice has been obtained from a person that is registered as an investment dealer in the jurisdiction. If the Company receives subscriptions from investors relying on the Existing Securityholder Exemption exceeding the maximum amount of the Private Placement, the Company intends to adjust the subscriptions received on a pro-rata basis.

The Units issued pursuant to the Private Placement, and the Existing Securityholder Exemption will be subject to a four-month hold period from the closing date of the Private Placement under applicable Canadian securities laws, in addition to such other restrictions as may apply under applicable securities laws of jurisdictions outside Canada.

The Company may pay finder’s fees to eligible finders in connection with the Private Placement, subject to compliance with applicable securities laws and Canadian Securities Exchange policies.

The securities being offered have not been and will not be registered under the U.S. Securities Act and may not be offered or sold in the United States, or to, or for the account or benefit of, U.S. persons or persons in the United States, absent registration or an applicable exemption from the registration requirements. This press 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 State in which such offer, solicitation or sale would be unlawful.

Ripsey Gold Project Overlimit Assay Results

About the Silver King

Discovered in 1875, the Silver King mine was one of Arizona ‘ s most important historic producers, yielding nearly 6 million ounces of silver at grades of up to 61 oz/t.  The Silver King mine sits only 3 km from the main shaft of the Resolution Copper project — a joint venture between Rio Tinto and BHP and one of the world ‘ s largest unmined copper deposits with an estimated copper resource of 1.787 billion metric tonnes at an average grade of 1.5% copper (1) . The unique land position is fully surrounded by Resolution Copper ‘ s claim block, offering strategic upside. Selected samples from small-scale production in the late 1990s returned grades as high as 644 oz/t silver (18,250 g/t) and 0.53 oz/t gold (15 g/t), indicating that high-grade mineralization remains.
