PRISMO METALS TO INCREASE HOT BRECCIA INTEREST TO 95%, SECURES OPTION FOR FULL CONTROL

Prismo Metals Inc. has entered into an agreement with Infinitum Copper Corp., whereby Prismo will increase its interest in the Hot Breccia copper project, located in the heart of Arizona's prolific copper belt, from 75 per cent to 95 per cent, In addition, Prismo has obtained an irrevocable option to acquire Infinitum's remaining 5-per-cent interest, providing a clear path to 100-per-cent interest in the project.

Alain Lambert, chief executive officer of Prismo, commented: "The absence of a clear mechanism to secure full ownership at Hot Breccia had previously limited our ability to fund drilling and pursue potential third party partnerships. The transaction announced today totally removes that constraint and materially improves the strategic flexibility of the project."

He added: "Prismo remains firmly committed to advancing Hot Breccia. The recent extension of certain milestone obligations under the option agreement with Walnut Mines LLC, the owner of the Hot Breccia claims, together with the deal announced today, provides the company with additional flexibility as we evaluate a range of strategic alternatives. Each of these pathways is intended to position Prismo to commence drilling on what we consider to be 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 Mines is solidly in favour of any action that moves Hot Breccia closer to a serious drill program. We are hopeful that this transaction will accomplish that goal in 2026. In our opinion, this property remains one of the best copper exploration opportunities in North America."

Under the terms of the transaction, Prismo will pay Infinitum $185,000 to acquire a 20-per-cent additional interest in the Hot Breccia project and assume all of Infinitum's remaining obligations under the option agreement to issue shares to Walnut, which is currently evaluated at approximately $54,000 through the issuance of Prismo common shares at a deemed issue price of 11 cents per share, subject to adjustments at closing. Prismo has also agreed to pay 5 per cent of any consideration received in connection with a transaction in which Prismo assigns its interest in Hot Breccia to a third party. The cash payment will be financed through a third party as an advance to the company and will not utilize its working capital, which is earmarked for the advancement of the Silver King project. Closing of the transaction is expected to take place on or around Jan. 16.

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 (Z-tipper electromagnetic) 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 of 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 m 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 historical 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 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 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 historical 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 and 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.
