Prismo Metals Assays up to 5.69% Copper at the Hot Breccia Project in the Arizona Copper Belt

Vancouver, British Columbia--(Newsfile Corp. - March 26, 2024) - Prismo Metals Inc. (CSE:PRIZ) (OTCQB: PMOMF) ("Prismo" or the "Company") is pleased to announce assay results for samples taken in February during our ongoing exploration program at the Hot Breccia Project located in the heart of the prolific Arizona Copper Belt. The Hot Breccia property hosts a cluster of hydrothermal breccia pipes originating from at least 1 kilometer depth that incorporated a wide range of wallrock fragments including variably copper and gold mineralized sedimentary and intrusive units. These include a fragment of mineralized magnetite skarn encased within a quartz diorite porphyry that assayed 5.69% copper, 0.24 g/t gold and 32.8 g/t silver. Limited historical drilling in the area intersected similarly mineralized magnetite skarn at depth, apparently in place, indicating that extensive porphyry-related copper mineralization occurs at depth in the system. Prismo's recent (2023) ZTEM geophysical survey shows a large conductive feature (Figure 5) adjacent to the historical drilling that is interpreted to be a Resolution-like(1) porphyry-skarn mineralized centre.

"The widespread high-grade copper and gold mineralization we're finding on the property, combined with the features we're seeing in the breccia, suggests a potential large, mineralized porphyry centre at depth," said Dr. Craig Gibson, Prismo's President and CEO. "Rio Tinto and BHP's proposed Resolution Copper underground mine is expected to become the largest copper mine in North America, capable of producing up to 25 percent of U.S. copper demand each year at an average grade of 1.5% copper(1). We are also excited to note that some breccia fragments are derived from the same favorable sedimentary units that host South-32's Taylor-Hermosa deposit(2) (Figure 3), further suggesting that strong potential exists at Hot Breccia for similar, extensive carbonate replacement style mineralization surrounding the postulated porphyry centre."
