Power Metallic Mines Inc.  (TSX-V: PNPN) (OTCBB: PNPNF) (Frankfurt: IVV1) is pleased to provide a release of assays from its fall drill program

Summer-Fall Drilling Release 4 – Lion

The summer-fall 2025 drilling program was designed to search for extensions to the Lion Zone, specifically down plunge from known mineralization, and to infill drilling the Lion deposit to define the zone geometry to a confidence level that would allow a future mineral resource estimate to be carried out to an Indicated Resource classification.

As assay results are returned from this exploration drilling, they have continued to successfully define the Lion mineralization. The holes in this release are extensions down-plunge from high-grade shoots that are internal to the Lion zone for future MRE modelling. Drilling reported here intersected mineralization below the central high-grade zone of Lion, including a high-grade palladium-platinum-gold-copper intersection of 8.40m @ 8.05% CuEqRec¹ included within 20.40m @ 4.11% CuEqRec¹ in hole PML-25-046; and 5.10m @ 9.86% CuEqRec¹ included in 8.60m of 6.34% CuEqRec¹ in hole PML-25-045.

Highlighting the polymetallic nature of Lion the reported results from hole PML-25-046 was expected to be a relatively low-grade hole based on initial observations based on the amount of copper mineralization in the core (veins, stringers, and disseminations). Subsequently the assay results indicated that the 20.4m of moderate copper mineralization (0.88% Cu) carried high values of Pd (5.01 g/t) as well as Pt and Au. Power Metallic is now developing logging procedures to help identify these higher-grade precious metal zones that form part of this orthomagmetic polymetallic deposit.

Extensional intersections on the west side of Lion included 7.66m @ 2.69% CuEqRec¹in hole PML-25-34a, again with significant metal value carried by Pd-Pt. These holes have largely confirmed the grade of the Lion zone as well as increasing the size of the interpreted higher-grade lodes.

Hole PML-25-036 is approximately 150m west of the main Lion zone. This intersection is indicative of another lens of polymetallic mineralization west of Lion and will be followed up by future drilling to expand this zone.

¹Copper Equivalent Rec Calculation (CuEqRec¹)

CuEqRec in represents CuEq calculated based on the following metal prices (USD) : 2,360.15 $/oz Au, 27.98 $/oz Ag, 1,215.00 $/oz Pd, 1000.00 $/oz Pt, 4.00 $/lb Cu, 10.00 $/lb Ni and 22.50 $/lb Co., and recovered grades based on recent locked-cycle metallurgical recoveries by SGS Canada Inc (see press release Jan 21, 2026).

“We have made a lot of progress on the Lion Zone. The continuity and growth of the higher-grade core of Lion zone with in-fill drill holes (MRE holes), coupled with our amazing metal recovery numbers that we reported a couple of weeks ago puts us in great shape to ramp up exploration this year. Commented Power Metallic Ceo Terry Lynch

Exploration Update

Power Metallic is expecting to receive the balance of the fall drill holes within the month of February. It will provide a detailed update on the exploration the company is conducting on Lion West, The Hydro lands, Tiger Deep and the Elephant exploration plays as well as initial exploration on the Li-FT acquisition ground. In addition, there will be further updates on the Lion Zone East expansion drilling following the recently recognized high grade east plunging mineralization structures extending from the Lion main zone.

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 ~212.86 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 JabalSaid 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.
