Vancouver, British Columbia, November 5th, 2025 TheNewswire – Prismo Metals Inc. (the ‘ Company ‘ ) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce that Walnut Mines LLC, the owner of the Hot Breccia claims optioned as to 75% by the Company, has agreed to extend certain dates to complete cash payments and exploration expenditures.

Alain Lambert, CEO 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 cooperation 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 LLC, 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 $1,750,000 from January 31, 2026 to January 31, 2027; and (ii) extend the milestone date to complete exploration expenditures of $2,000,000 from January 31, 2027 to January 31, 2028 and (iii) extend the milestone date to complete the final cash payment of $275,000 to Walnut Mines LLC from January 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 (see Figure 1).

Figure 1. Location of the Hot Breccia Project in the Arizona Copper Belt.

Historical drilling carried out 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 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 cross cutting 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 Cu-bearing skarn, the 2023 ZTEM survey as well as the results of an AI study. The anomalous target area identified in Prismo ‘ s modelling measures 1,100 meters by 1,150 meters.

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 kilometers 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 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 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 (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 dacite dikes 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.

Toronto, Ontario November 4, 2025 TheNewswire – Laurion Mineral Exploration Inc. (TSX.V: LME | OTC: LMEFF) (‘LAURION’ or the ‘Corporation’) is pleased to announce encouraging results from its 7,700-metre Summer 2025 drill exploration program at the 100%-owned Ishkõday Project, located 220 km northeast of Thunder Bay in Greenstone, Ontario. The first five drill results were announced in the Corporation’s press releases dated August 19, 2025 and September 23, 2025, respectively, which targeted the high-grade gold-bearing vein systems of the Sturgeon River Mine area. Reference is also made to the Corporation’s press releases dated September 5, 2025, May 27, 2025 and May 8, 2025.

The reported drill holes below, LME25-061 and LME25-062, totalling 954 m were designed to evaluate the mineralized system at the historic Brenbar Mine area, stepping out to the north and northeast of the of the historic mine shaft.

Highlights of Drill Holes LME25-061 and LME25-062

LME25-061

• 2.70 m @ 0.22 g/t Au from 152.6 m to 155.3 m

• 2.50 m @ 0.20 g/t Au from 167.5 m to 170 m

• 2.25 m @ 0.88 g/t Au from 213.85 m to 216.10 m, including 1.70 m @ 1.10 g/t Au from 214.4 m

LME25-062

• 3.00 m @ 0.49 g/t Au from 304.0 m to 307 m, including 1.0 m @ 1.34 g/t Au from 304.0 m

• 2.00 m @ 0.50 g/t Au from 111.0 m to 113.0 m, including 0.5 m @ 1.45 g/t Au from 111.80 m

• 1.20 m @ 0.76 g/t Au from 105.7 m to 106.9 m, including 0.7 m @ 1.07 g/t Au from 105.7 m

• 1.05 m @ 2.68 g/t Au from 117.6 m to 118.65 m, including 0.5 m @ 5.18 g/t Au from 118.15 m

• 1.15 m @ 0.39 g/t Au from 310.7 m to 311.85 m

• 1.10 m @ 1.63 g/t Au from 454.4 m to 455.5 m

These new intercepts not only confirm the continuity of gold-bearing structures near the Brenbar Shaft, but also demonstrate how far our understanding of Ishk õ day has advanced since the early 2010 drilling campaigns,’ said Cynthia Le Sueur-Aquin, President and CEO of Laurion Mineral Exploration Inc. ‘Our 2025 drill core is fully oriented, allowing precise structural interpretation and integration into our evolving 3D geological model — a critical step toward defining the geometry and scale of the mineralized system.’

The 2025 drill program targeted a cluster of complex folded gold-bearing vein structures in the Brenbar Shaft namely No 1, 2, 2A and No. 7 vein sets confirmed in historic drilling by Prodigy Gold Inc. ( Jamie Solomon & Jerry Light, June 13, 2011 ). That work returned multiple higher-grade intercepts, including 3.77 g/t Au over 1.30 m and 1.33 g/t Au over 1.0 m in BB09-03 , 5.50 g/t over 2.5 m, 1.39 g/t Au over 1.0 m and 1.47 g/t Au over 1.0 min BB09-04 , 2.29 g/t Au over 1.10 m and 0.39 g/t Au over 15.90 m in BB09-09 , 0.549 g/t Au over 12.50 m in BB09-10 , and 1.56 g/t Au over 1.0 m, 0.51 g/t Au over 6.30 m, 3.26 g/t Au over 0.80 m and 0.66 g/t Au over 8.20 min BB10-27 which tested No. 15 Vein, #25 trench vein . The results confirm high-grade quartz-vein hosted gold within sheared volcanic rocks. They provide the basis for LAURION’s 2025 program to test continuity and strike length at Brenbar, and to collect oriented core for detailed structural analysis and 3D modeling.

Note: (Intervals represent core length; true widths are estimated at ~70–90% of reported intervals.)

Sampling and QA/QC Protocols

All drill core is transported and stored inside the core facility located at the Ishkõday Project in Greenstone, Ontario. LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a ‘rice’ white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (InductivelyCoupledPlasma – AtomicElement-Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.

A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QAQC were verified, and no contamination or bias have been observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Beardmore and moved to the core storage facility at the Ishkõday Project.
