Prismo Engages Windfall Geotek for Data Analysis at Hot Breccia

(TheNewswire)

Vancouver, British Columbia TheNewswire – August 18th, 2025 Prismo Metals Inc. (the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce that its has engaged Windfall Geotek Inc. to apply its proprietary Windfall AI System to integrate and analyze geophysical data, topography data and drill hole data at Prismo’s Hot Breccia copper project located in Arizona.

Dr. Craig Gibson, Chief Exploration Officer of Prismo Metals commented: ‘The Hot Breccia Project should be an ideal place to apply the Windfall AI System. It lies in the world-famous Arizona copper belt, between several very well understood world-class copper mines including Christmas, Morenci, Ray and Resolution. (Figure 1) Hot Breccia shows many features in common with these neighboring systems, most prominently a swarm of porphyry dikes and series of breccia pipes containing numerous fragments of well copper-mineralized rocks mixed with fragments of volcanic and sedimentary derived from considerable depth.’

Gord Aldcorn, President of Prismo said: ‘Prismo remains committed to advancing its Hot Breccia copper project, located in the heart of the Arizona copper belt. The engagement of Windfall Geotek is consistent with that commitment. Their work will provide valuable information as we continue to hold discussions with potential strategic partners present in the district or wanting to gain a foothold in the district. The goal remains to conduct a minimum of 5,000 meters of drilling. Results from the Windfall Geotek study are expected to be received by the beginning of September.’

Windfall Geotek, located in Montreal, Canada, is a mining and technology services company and a leader in the application of Artificial Intelligence (AI) for mineral exploration since 2005. The Windfall AI System is a state-of-the-art computerized analysis method that uses the latest Artificial Intelligence (Machine Learning) and pattern recognition algorithms to analyze large digital exploration data sets and produce exploration targets.

Historical drilling was carried out at Hot Breccia in the mid to late 1970’s by a Rio Tinto subsidiary intersected high-grade copper mineralization at depths ranging from 640 to 830 meters below the surface in several holes that targeted one of the magnetic highs, believed to be caused by the magnetite skarn that was cut in the holes and that occurs in xenoliths in cross cutting dikes exposed at the surface. Prismo believes those intercepts cut the periphery of the upper portion of a large mineralized system as interpreted from our exploration program. Historical drill holes cut high grade skarn mineralization including 23 meters with 0.54% Cu at 640 meters depth (hole OC-1), 18 m with 1.4% Cu and 4.65% Zn at 830 meters depth (hole OCC-7), and 7.6 m with 1.73% Cu and 0.11% Zn at 703 meters and 4.6 meters with 1.4% Cu and 0.88% Zn at 716 meters (OCC-8).

Mineralization occurs within a several hundred-meter-thick altered zone hosted in favorable Paleozoic carbonate rocks that underly a sequence of Cretaceous andesitic volcanic rocks. These carbonates are the same rocks that host the high-grade copper mineralization at Freeport’s nearly Christmas mine.

The historic drilling intersected a blind mineralized intrusion associated with the skarn mineralization, providing an immediate drill target that is believed to be the source of the mineralization at Hot Breccia (Figure 2). Several magnetic highs in the region surrounding the proposed intrusion may also indicated buried skarn mineralization and provide additional exploration targets.

About Hot Breccia

The Hot Breccia property consists of 1,420 hectares in 227 contiguous mining claims located in the world class Arizona Copper Belt between several very well understood world-class copper mines including Morenci, Ray and Resolution (Figure 1). Hot Breccia shows many features in common with these neighboring systems, most prominently a swarm of porphyry dikes and series of breccia pipes containing numerous fragments of well copper-mineralized rocks mixed with fragments of volcanic and sedimentary derived from considerable depth. Prismo performed a ZTEM survey last year that identified a very large conductive anomaly directly beneath the breccia outcrops.

Sampling at the project has shown the presence of copper mineralization associated with polylithic breccia pipes that transported fragments of strongly mineralized carbonate rocks to the surface from depths believed to be 400-1,000 meters. Drilling deep holes is necessary to tap into the source of these mineralized fragments found at surface.

Assay results from historic drill holes are unverified as the core has been destroyed, but information has been gathered from memos, photos and drill logs that contain some, but not all, of the assay results and descriptions. Technical information from adjacent or nearby properties does not mean nor does it imply that Prismo will obtain similar results from its own properties.

Data on previous drilling and geophysics is historical in nature and has not been verified, is not compliant with NI 43-101 standards and should not be relied upon; the Company is using the information only as a guide to aid in exploration planning.
