• Prismo Metals outlined a porphyry-copper exploration thesis at its Silver King project in Arizona, citing a deep drill hole that intersected quartz monzonite intrusion with strong potassic alteration and local chalcopyrite below historic mine workings.
• Phase 1 drilling totaled 8 holes for 1,272 meters, including a 1,600-foot (488-meter) deep test that management views as first clear evidence of hypogene copper mineralization at depth beneath shallow, high-grade silver zones.
• Assay results from all eight holes are expected in June 2026, with surface mapping and geochemistry to be released at the same time.
• Phase 2 work targets a larger, deeper step-out drill program, with downhole geophysics planned to refine 3D targeting; drill program design is expected in July/August 2026.
• Presentation also highlighted proximity to Resolution Copper, described as a Rio Tinto-BHP joint venture with an estimated 1.859 billion metric ton resource grading about 1.52% copper, placing Silver King about 3.4 km from the deposit.
