TORONTO, June 23, 2026 /PRNewswire/ – Power Metallic Mines Inc. (the “Company” or “Power Metallic”) (TSXV: PNPN) (OTCBB: PNPNF) (Frankfurt: IVV1) is pleased to provide additional assay results from its Winter 2026 drill program.
Summary
These additional assays from Power Metallic’s winter 2026 drill program is nearing the completion of winter drill results to be used for the initial NI-43-101 Mineral Resource Estimate (MRE) on Lion. Completion and reporting of the MRE estimates on Lion and the Nisk deposit is scheduled for the end of July. This MRE will form the basis for a Preliminary Economic Assessment (PEA) to begin immediately following the completion of the MRE.
Lion Zone MRE In-fill program
This news release includes drill holes defining the western side of the Lion Zone close to surface (Figure 1). All holes are in preparation for the 2026 Mineral Resource Estimate (MRE). The infill drill holes in this release were drilled to delimit the western side of Lion to increase the confidence of modelling the zone, particularly within the range of a potential future open pit.
In-fill drill holes in the shallow central parts of the deposit continue to report good near surface grades as evidenced by PML-26-115 which intersected high-grade copper near surface with 13.30 m @ 3.98% CuEqRec1 at 25m below surface, and PML-26-105 which intersected 5.26 m @ 8.45% CuEqRec1 at approximately 140m below surface (Table 1 and Figure 1).
Drill holes included in Figure 1 but not in the table of Lion results (Table 1) occur on the western side of Lion, delimiting the western edge for MRE resource modelling. These holes did intersect the favourable mineralized structure, but had low grade assays, including individual assays of up to 0.57% Cu and 1.22 g/t Pd. The fact that these holes are within a few 10s of meters of very high grade intersections is important for the continuing exploration in the Lion area. Understanding that good structure with low grade mineralization in exploratory drilling could indicating potential proximity to higher grades will help vector current and future drilling programs.

About Power Metallic Mines Inc.
Power Metallic is a Canadian exploration company focused on advancing the Nisk Project Area (Nisk–Lion–Tiger)—a high–grade Copper–PGE, Nickel, gold and silver system—toward Canada’s next polymetallic mine.
On 1 February 2021, Power Metallic (then Chilean Metals) secured an option to earn up to 80% of the Nisk project from Critical Elements Lithium Corp. (TSX–V: CRE). Following the June 2025 purchase of 313 adjoining claims (~167 km²) from Li–FT Power, the Company now controls ~330 km² and roughly 50 km of prospective basin margins.
Power Metallic is expanding mineralization at the Nisk and Lion discovery zones, evaluating the Tiger target, and exploring the enlarged land package through successive drill programs.
Beyond the Nisk Project Area, Power Metallic indirectly has an interest in significant land packages in British Columbia and Chile, by its 50% share ownership position in Chilean Metals Inc., which were spun out from Power Metallic via a plan of arrangement on February 3, 2025.
It also owns 100% of Power Metallic Arabia which owns 100% interest in the Jabul Baudan exploration license in The Kingdon of Saudi Arabia’s Jabal Said Belt. The property encompasses over 200 square kilometres in an area recognized for its high prospectivity for copper gold and zinc mineralization. The region is known for its massive volcanic sulfide (VMS) deposits, including the world-class Jabal Sayid mine and the promising Umm and Damad deposit.

QAQC and Sampling
GeoVector Management Inc (“GeoVector”) is the Consulting company retained to perform the actual drilling program, which includes core logging and sampling of the drill core.
All core in this news release is either HQ or NQ sized core. Drill core is re-fitted and measured. Geotech on core includes photographs (wet & dry), rock quality index, magnetic susceptibility, conductivity, and recovery estimates. Core is logged for lithology, mineralogy, and structural features, and sample intervals are delineated and tagged.
Sampled core is mechanically sawn, and half-core is retained for future reference. GeoVector’s QAQC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream with a stringent review of all results. QAQC and data validation was performed, and no material errors were observed.
All samples were submitted to and analyzed at Activation Laboratories Ltd (“Actlabs”), a commercial laboratory independent of Power Metallic with no interest in the Project. Actlabs is an ISO 9001 and 17025 certified and accredited laboratories. Samples submitted through Actlabs are run through standard preparation methods and analysed using RX-1 (Dry, crush (< 7 kg) up to 80% passing 2 mm, riffle split (250 g) and pulverize (mild steel) to 95% passing 105 μm) preparation methods, and using 1F2 (ICP-OES) and 1C-OES – 4-Acid near total digestion + Gold-Platinum-Palladium analysis and 8-Peroxide ICP-OES, for regular and over detection limit analysis. Pegmatite samples are analyzed using UT7 – Li up to 5%, Rb up to 2% method. Actlabs also undertake their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration.
