Power Metallic Intercepts 5.35 Meters of 11.97% Cu in Hole 25-022 Infill Drilling Expanding the Lion Zone and Updates on fall, Winter Drill Program and Land Assembly

TORONTO – Power Metallic Mines Inc.(the ‘Company’ or ‘Power Metallic’) (TSXV: PNPN) (OTCBB: PNPNF) (Frankfurt: IVV1) is pleased to provide a release of assays from its summer drill program, an update on its land assembly activities together with an outlook to the fall and winter key exploration objectives.

Summer Drilling Release 2 – Lion – Tiger Area

The summer drilling program was designed to search for extensions to the Lion Zone, specifically down plunge from known mineralization, and to infill drill, including ‘edge’ holes, on the Lion zone 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.

Extensional Drilling Results

Extensional drilling was slow during the summer program as technical problems with the helicopter supported drills led to lost holes (such as holes PML-25-019 and 024a in this release) that did not reach the mineralization horizon for Lion. Hole PML-25-017 has extended the zone to the west but failed to intersect the High-grade massive sulphide portion of the Lion zone and returned a disseminated zone of 7.00m @ 1.41% CuEqRec1 that confirms the extension of the mineralizing Lion structure which will see continued follow-up in the 2025 fall program.

The Company intends to use more powerful skid drills when possible going forward when testing the Lion Zone extension at depth to avoid similar issues.

Mineral Resource(MRE) Drilling Results

In-fill drilling has successfully defined mineralization along some of the high-grade shoots that are internal to the Lion zone and defined the edges of the Lion zone for future MRE modelling. Drilling reported here intersected mineralization on Hanging-wall, High-grade, and Footwall portions of Lion, including High-grade sulphide intersections of 6.85m @ 13.15% CuEqRec1 in hole PML-25-022 (inclusive of 5.35m of 16.35% CuEqRec1), and 5.90m @ 10.43% CuEqRec1 in hole PML-25-022, included within 27.50m @ 2.75% CuEqRec1. All the in-fill drilling to date has largely confirmed the size, grade, and orientation that was modelled prior to the drilling, leading to increased confidence in the interpreted zones.

Terry Lynch, CEO of Power Metallic states ‘These are some amazing high-grade intersections. Any hole delivering over 50 meter % (Grade % Metres) scores is an extremely lucrative hole. We have extended the known resource area and increased our understanding of the plunge of the Lion Zone. Our objective with drilling this summer was to extend the Lion Zone which is being accomplished and also to discover the next Lion Zone. That part we have not yet completed. But we have gained excellent insight that is guiding our fall and winter drilling program. In addition, we didn’t drill our highest priority drill targets due to their proximity to the land assembly activities we were working on. With that ground now secured we can discuss those targets below.’

Copper Equivalent Rec Calculation (CuEqRec1)

CuEqRec 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 a recovery grade of 80% for all commodities, consistent with comparable peers.

Tiger Deep Target

Three holes reported here (PML-25-021, 026a, 030) were drilled below the depth resolution of the recent 2025 airborne VTEM survey completed by Power Metallic. These holes were testing the area between Lion and Tiger to intersect the mineralized horizon and provide drill holes for BHEM surveys. Although essentially blind exploration drill holes, evidence from previous work, including shallow drilling, including intercepts of >2% Ni with >5% CuEq, suggested a high potential for mineralized zones between Lion and Tiger.

Hole PML-25-026, drilled closest to Lion returned no significant assays, while the BHEM survey off-hole conductors were pointing to the presence of the Lion deposit. Hole PML-25-021 intersected a modest Lion style mineralized zone (3.70m @ 1.48% CuEqRec1) and indicated an off-hole anomaly separate from the Lion deposit. This location is proximal to a postulated off-set shoot from the Lion zone, or possibly could be indicating a new Lion style zone.

Hole PML-25-030 did not intersect significant mineralization, but the BHEM survey produced a large, possibly thick bodied anomaly deeper and to the east of the hole. The BHEM panel defined at Tiger Deep represents one of the biggest EM panels identified to date, larger than the original Lion airborne VTEM panel. This location is proximal to a postulated ‘Deep Tiger’ target that is based on reinterpretation of previous Tiger drilling and surface mapping that suggests Tiger is made up of ‘rip-up’ blocks of massive sulphides carried in a tonalitic intrusion from a deeper and larger deposit. Both the PML-25-030 and PML-25-021 BHEM anomalies are being prioritised for drilling (the PML-25-030 BHEM is currently being drilled).
