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 (Table 1, Figure 1)
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 (Table 1, Figure 1)
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.”

Note: Reported length is downhole distance; true width based on model projections is estimated as 85% of downhole length

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 (Table 1, Figure 1)

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 (Figure 1) 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).

Land Assembly Activities

Power Metallic’s discovery of the Lion Zone changed the geological understanding for the basin. We now understand that the Lion zone and the Nisk deposits are parts of a remobilized polymetallic Ni-Cu system, which are rare, but historically have always occurred at district scales and produce giant deposits. Based on this knowledge over the last several months we assembled more than a 600% increase in our land package growing from 46 km² to 313 km².

For now, we are in sole possession of the geological understanding about what works in respect to making discoveries in this regional Basin. Our search encompasses the entire basin, but we have acquired the local basin edges as the lowest hanging fruit to explore first (shallower deposits close to known mineralization), and this was the central strategy for acquiring the Li-FT ground in June (Figure 2). Subsequent exploration, including airborne VTEM and magnetics and field mapping and sampling, have developed dozens of target areas for Cu- Ni mineralization. These are currently being prioritized and drilled following receiving drill permits (ATIs in Figure 2).

Arguably our most important acquisition is land that had been under an exclusion from Hydro Quebec surface leases (Hydro ground – Figure 2). With the assistance of the James Bay Cree, we were able to successfully convince the Quebec government to open these lands for mineral staking, and we staked it in late September. This area is most important to Power Metallic as it covers the extension of the Lion mineralizing system (i.e. our discovery). Prior to the acquisition of the Hydro ground, we did not have claim ownership over a target area that contains an important fold axis through the mineralized geological horizons as seen by 2D Residual magnetic intensity interpreted ultramafic structures (Figures 3 and 4). In addition, the entire north limb of this fold hosting the strike length between Lion and Nisk was too close to the old property boundary to safely explore the ground, thus delaying exploration on our highest priority target.

The Hydro area covers an interpreted fold hinge that could provide a thickening of projected Cu and Ni mineralization proximal to the Lion and Tiger zones. An analogue deposit we believe is comparable to the Nisk and Lion deposits is the Thompson nickel deposit. A cross section of the Thompson deposit is shown in Figure 4.

The potential of a fold hinge target is supported by magnetic data (Figures 4 and 5) that has modelled the folded ultramafic host rocks. Subsequent BHEM anomalies in holes PN-24-064 (Figure 4) and PML-25-030 and 021 further suggest a large body of mineralization is coincident with the anticipated fold hinge. The BHEM anomaly detected in PN-24-064 had greater than one hundred meters of build up at the bottom of the hole however the hole didn’t have the required length to show the full anomaly. Re-entry of PN-24-064 is underway to extend the hole a further 250 meters – to fully define where the BHEM panel exists, and to potentially intersect a portion of the conductive body.

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.
