Prismo Metals Closes Hot Breccia Copper Project Transaction and Provides Drilling Update

Vancouver, British Columbia — March 5, 2026 — Leads & Copy —

Prismo Metals Inc. has announced the closing of a previously announced transaction with Blade Resources Inc., assigning all rights, interests, and obligations in the Hot Breccia copper project in Arizona to Blade. In return, Prismo received 6,755,000 common shares of Blade and a cash payment of $185,000.

Following the transaction, Prismo owns approximately 24% of Blade’s issued and outstanding shares, making it Blade’s largest single shareholder. Prismo retains the right to nominate one representative to Blade’s board of directors and participation rights in future equity offerings to maintain its ownership percentage.

Prismo’s CEO, Alain Lambert, stated that Hot Breccia is a compelling copper exploration opportunity and anticipates drilling this year, backed by Blade’s principals and financial backers.

Dr. Craig Gibson, Chief Exploration Officer of Prismo, also provided an update on the drilling program at the Silver King project in Arizona. The first drill hole, SK-26-01, reached a total depth of 477 feet (145 meters) and intersected two small voids likely from underground workings. Quartz veining extended from this level for about 100 feet down hole, with visible sulfide minerals and confirmed silver minerals, including native silver, using a handheld XRF analyzer. Minerals such as freibergite, stromeyerite, and acanthite are also present. The second hole, SK-26-02, is currently at a depth of 155 feet.

The Phase 1 drill program at Silver King includes 1,000 meters of diamond drilling to test the upper portion of the mineralized body. Additional drilling may be completed to test lower in the structure and adjacent mineralized areas. Initial drilling is estimated at 1,000 meters in nine holes, with a second phase dedicated to deeper levels and areas adjacent to the historic mine. The silver mineralization at Silver King is similar to the nearby Magma Mine.

The Magma Mine and Silver King Mine share a common regional geological framework in the Superior Mining District, characterized by a Precambrian to Paleozoic stratigraphic sequence including Pinal Schist basement, diabase sills, the Apache Group sediments, and Paleozoic limestones like the Martin Formation, all tilted eastward and intruded by Laramide-age igneous bodies such as quartz diorite stocks and andesite sills. While both exhibit fault-controlled mineralization—east-trending faults and veins with hydrothermal alteration like silicification and potassic zoning—Silver King features epithermal-mesothermal silver-dominant veins in porphyry with minerals like stromeyerite, tetrahedrite, and acanthite, contrasting Magma's mesothermal copper-focused veins and limestone replacement ores (mantos) rich in chalcopyrite and bornite. This vertical zoning suggests Silver King's shallower silver-enriched system may transition into deeper copper styles like Magma's, with overlapping sulfides indicating potential for untapped polymetallic extensions, especially given Magma's link to the underlying Resolution Copper porphyry deposit.

The transaction provides strategic benefits, including value creation, access to capital without direct dilution to Prismo shareholders, and strategic focus. Prismo will focus on its remaining Arizona projects, Silver King and Ripsey Gold, while Blade advances Hot Breccia. Blade’s potential 100% ownership of Hot Breccia may attract majors or strategic buyers.

Prismo’s early warning report will be available under Blade’s profile on SEDAR+.

Dr. Craig Gibson, a Qualified Person as defined by NI-43-01 regulations, has reviewed and approved the technical disclosures.

Prismo Metals Inc. is focused on advancing its Silver King, Ripsey, and Hot Breccia projects in Arizona and its Palos Verdes silver project in Mexico.

Blade Resources is focused on development of North American copper and precious metals projects.
