Prismo extends milestone dates for Hot Breccia option

Mr. Alain Lambert reports PRISMO METALS PROVIDED EXTENSIONS ON HOT BRECCIA COPPER PROJECT Walnut Mines LLC, the owner of the Hot Breccia claims optioned as to 75 per cent by Prismo Metals Inc., has agreed to extend certain dates to complete cash payments and exploration expenditures. Alain Lambert, chief executive officer of Prismo, said: "Prismo remains firmly committed to advancing the Hot Breccia project, located in the heart of Arizona's historic copper belt. We appreciate the co-operation of Walnut Mines LLC in extending certain milestone obligations, which provides the company with additional flexibility as we assess a range of strategic alternatives. Each of these paths is designed to position Prismo to commence drilling on what we consider one of the most compelling copper exploration opportunities in Arizona and the broader United States." Dr. Linus Keating, manager of Walnut Mines, enthusiastically commented: "Walnut and Prismo remain firmly dedicated to advancing Hot Breccia towards drill discovery. Accomplishing that goal requires that we continue to work together and support each other. This extension will provide the necessary time and better focus resources to succeed at Hot Breccia." More specifically, the extensions are as follows: (i) extend the milestone date to complete exploration expenditures of $1.75-million from Jan. 31, 2026, to Jan. 31, 2027; (ii) extend the milestone date to complete exploration expenditures of $2-million from Jan. 31, 2027, to Jan. 31, 2028; and (iii) extend the milestone date to complete the final cash payment of $275,000 to Walnut Mines from Jan. 31, 2026, to July 31, 2026. Prismo's Hot Breccia project lies at the heart of the Arizona copper belt, which hosts several globally significant porphyry copper deposits. Examples of these significant deposits are Freeport McMoRan's Miami-Inspiration mining complex, BHP's San Manuel mine, Rio Tinto and BHP's Resolution deposit, and others. Historical drilling carried out in the mid- to late 1970s by a Rio Tinto subsidiary intersected high-grade copper mineralization at depths ranging from 640 to 830 metres below surface. Several holes targeted an area with a coincident magnetic high, believed to be caused by magnetite skarn that was cut in the drill holes and that occurs in xenoliths in crosscutting dikes exposed at the surface. Prismo believes those intercepts may represent the periphery of the upper portion of a large mineralized system. Support for the company's mineralization model at the project comes from several sources, including the results of historical drilling, geophysical surveys, distribution of dikes with xenoliths of copper-bearing skarn, the 2023 ZTEM survey as well as the results of an AI (artificial intelligence) study. The anomalous target area identified in Prismo's modelling measures 1,100 metres by 1,150 metres. Dr. Craig Gibson, chief exploration officer of Prismo, stated: "The copper exploration target at Hot Breccia has geophysical, geochemical and geological features characteristic of many porphyry copper deposits. The project area has a regional setting similar to BHP-Rio Tinto's Resolution copper deposit, located 40 kilometres to the northwest of Hot Breccia and which is considered to be one on the greatest copper discoveries in the history of North American mining." He added: "The drill program is intended to drill through the entire prospective Paleozoic carbonate stratigraphy into the postulated porphyry body/breccia zone. The exploration team will take advantage of geological information provided by each hole during drilling to refine targeting of subsequent holes." Historical drill holes cut high-grade skarn mineralization, including 23 metres with 0.54 per cent copper at 640 metres depth (hole OC-1), 18 metres with 1.4 per cent copper and 4.65 per cent zinc at 830 metres depth (hole OCC-7), and 7.6 metres with 1.73 per cent copper and 0.11 per cent zinc at 703 metres and 4.6 metres with 1.4 per cent copper and 0.88 per cent zinc at 716 metres (OCC-8). Mineralization occurs within a several-hundred-metre-thick altered zone hosted in favourable Paleozoic carbonate rocks that underlie a sequence of Cretaceous andesitic volcanic rocks. These carbonates are the same rocks that host the high-grade copper mineralization at Freeport's nearby 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. 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. Hot Breccia shows many features in common with these neighbouring systems, most prominently a swarm of porphyry dikes and a 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 (Z-tipper electromagnetic) 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 dacite dikes that transported fragments of strongly mineralized carbonate rocks to the surface from depths believed to be 400 to 1,000 metres. 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 are historical in nature, have not been verified, are not compliant with National Instrument 43-101 standards and should not be relied upon; the company is using the information only as a guide to aid in exploration planning. Qualified person Dr. Craig Gibson, PhD, CPG, a qualified person as defined by NI 43-01 regulations and chief exploration officer and a director of the company, has reviewed and approved the technical disclosures in this news release.
