/CNW/ -

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 (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% CuEqRec

1

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% CuEqRec

1

in hole PML-25-022 (inclusive of

5.35m

of 16.35% CuEqRec

1

), and

5.90m

@ 10.43% CuEqRec

1

in hole

PML-25-022, included within

27.50m

@ 2.75% CuEqRec

1

. 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 (CuEqRec

)

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% CuEqRec

1

) 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).

just below the next image.

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 km

2

to 313 km

2

.

Figure 2: Land package showing land additions (Li-Fi & Hydro Land Expansion and new claims) (CNW Group/Power Metallic Mines Inc.)

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.

Figure 3: Nisk / Lion / Hydro land showing 2D Residual magnetic intensity of interpreted ultramafic structures and fold hinge (CNW Group/Power Metallic Mines

Inc.)

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.

Figure 4: Cross-section through the Thompson Structure facing northeast (line Y-Y’, figure 9; Bleeker 1990). (CNW Group/Power Metallic Mines Inc.)

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.
