Prismo Metals Assay Results at Silver King Show Highs of 1.73% copper, 30 ppm molybdenum, 1,362 g/t silver, 4.1% lead, and 1.3 g/t gold

Prismo Metals Inc. (the “Company”) (CSE: PRIZ) (OTCQB: PMOMF) is pleased to announce assay results from its previously reported reconnaissance program at its Silver King Project in central Arizona (see news release dated May 12, 2026).

Additional days of field work are planned to complete coverage of the property, together with collection of approximately 25 more samples.

Highlights of the Reconnaissance Program Collected 23 rock samples, with results showing highs of 1.73% copper, 30 ppm molybdenum, 1,362 g/t silver, 4.1% lead, and 1.3 g/t gold ( Table 1 Completed 50% of the planned reconnaissance geologic mapping and sampling, progressed from Peachville Wash westward through Silverado Wash and inward toward the central Silver King shaft, including portions of Comstock Wash and the Crown zone ( Figure 1 ).

Mapped two broad, apparently separate “pyrite halo” zones, one approximately 800 m wide necked down to the south but open to the north, and a second centered on Silver King extending roughly 600 m wide northwest by at least 1,300 m northeast, with potential to expand further.

Discovered previously unmapped hydrothermal/magmatic breccias in Silverado Wash exhibiting milled polylithic fragments in a chlorite-pyrite matrix, some exhibiting pyrite, chalcopyrite and/or copper oxides, invaded by later quartz diorite; and a second similar polylithic breccia (lacking pyrite) located 700 m to the southwest. The Crown stockwork may be an additional hydrothermal breccia, known to assay good gold and copper values (reported previous...
