The summer drilling program was designed to search for extensions to the Lion Zone, specifically down plunge from known mineralization, and to infill drill on 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.
Lion Resource Drilling (Table 1, Figure 1) Drilling has successfully defined mineralization extending down-plunge some of the 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 High-grade sulphide intersections of 4.40m @ 14.34% CuEqRec1 in hole PML-25-029b included within 20.40m of 3.58% CuEqRec1), and 1.59m @ 27.92% CuEqRec1 in hole PML-25-025, included in 19.8m of 2.71% CuEqRec1). Extensional intersection on the west side of Lion included 2.65m @ 17.79% CuEqRec1 in hole PML-25-31 included within 8.10m of 7.13% CuEqRec1). These holes have largely confirmed the grade of the Lion zone as well as increasing the size of the interpreted high grade lodes.

1Copper 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.
Terry Lynch, CEO of Power Metallic states "another good round of results showing very solid increases in the known mineralized area in the Lion Zone. At the moment even as we continue to test the extension of Lion and grow its mineralized area we have three strategic target areas supported by geology and borehole EM that look promising to deliver our next big breakthrough. Hole 64 which we talk about below and the very promising large off hole anomaly that sits in our interpreted fold hinge will be targeted by a series of holes as soon as drilling commences in 2026. This delay is to enable the heavier land rigs to be mobilized for this deep drill target. Tiger Deep the anomaly we discussed in our last release is being targeted prior to the Christmas break as are initial holes on the Hydro Lands.
Our integrated geophysical and geochemical toolkit has delivered for us in the past, and our exploration team has never been more optimistic than it is today. We are well funded for our 2025–2026 work programs and have announced our plan to list on the NYSE to access deeper U.S. capital markets. As we move into the upcoming winter and summer 2026 drill campaigns across the district, we've asked the team to systematically pursue the highest–priority targets, and while we haven't yet defined a second Lion or Nisk–style zone, we believe this is one of the most target–rich exploration opportunities over the next 12 months."
Nisk East Drilling (Table 1) Drilling at the Nisk East target includes holes PMN-25-005 thru PMN-25-011. Modest intersections of Ni-Cu-Pd mineralization was intersected in holes PMN-25-005, 008 and 011, including 4.00m of 2.34% CuEqRec1 in hole PMN-25-005. The Nisk East area is now being re-assessed with the recent land acquisition to the west (see news release November 4, 2025) which now allows Power Metallic to effectively target the extension of the geology that hosts this Ni-Cu system (Figure 2) and is on strike with the Lion and recently intersected Lion West zone (assays pending).
Power Metallic has also received assay results from the first 7 holes on the recent Li-FT acquisition (PMX-25-001 thru PMX-25-007). All holes were targeting airborne EM anomalies, and all holes intersected semi-massive to massive sulphides explaining the EM conductors. No significant metal values were intersected. Currently the PMX program is focusing on the recently acquired 'Hydro Lands' which is interpreted to be the folded extension of the Nisk-Lion system (see news release November 4, 2025). Drill permits have now been granted for this area allowing drilling to commence on this important target area.
Lion-Tiger Deep Target 'Deep Tiger' is a target that is based on reinterpretation of previous Tiger drilling that suggests Tiger is made up of 'rip-up' blocks of massive Ni-Cu sulphides carried in a tonalitic intrusion from a deeper larger deposit (Figure 3). This is supported by the fact that Tiger massive sulphides are hosted in a late tonalitic intrusion, and that recent surface mapping in the area discovered similar 'rip-up' blocks in outcrop (Figure 4) of both massive sulphides, and ultra-mafic in tonalite intrusions. Using various vectoring techniques Power Metallic believes it is directing exploration proximal to the source of this mineralization.
As reported on November 4, 2025, three holes (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.
As previously reported 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 Lion style mineralization (3.70m @ 1.48% CuEqRec1) and indicated an off-hole anomaly (Figure 2) east of the Lion deposit. Subsequent drilling of this BHEM off-hole target (PML-25-038) intersected more Lion style mineralization (assays pending) and BHEM surveys are currently being conducted on this hole.
The most easterly hole, PML-25-030 (assays pending) did not intersect significant visual mineralization, but the BHEM survey produced a large, possibly thick bodied anomaly deeper and to the east of the hole. This BHEM panel was tested by hole PML-25-035 (assays pending), which intersected sulphide mineralization in ultra-mafic host rock. This better refined the off-hole BHEM anomalies (Figure 2) which are currently being tested with drilling.
Lion-Tiger Deep Target – Hole PN-24-064 During drilling in 2024 on the Lion deposit, one hole, PN-24-064 was extended well beyond the Lion Zone and the hole ended at 1046 meters. Subsequent BHEM surveys indicated a very large off-hole anomaly, but the full anomaly couldn't be modelled as the conductor was below and in front of the end of the hole. This hole was subsequently extended 300 meters (end at 1347 meters) and resurveyed with BHEM. This has resulted in the largest off-hole conductor to date on the project.
This conductor stretches in front of the mineralization and conductors developed in holes PML-25-021, 030, 035 and 038 (Figure 1). It sits on both our original Nisk lands and the Li-FT acquisition claims which Power Metallic own 100% (Figure 2). The BHEM panel is on strike with the newly acquired 'Hydro Lands'. It occurs in the interpreted location of a fold hinge which has developed into a priority target area for Power Metallic to find more Cu-Ni mineralization.
The location of the anomaly, its large size, its proximity to subsidiary BHEM anomalies, and indications of mineralization (Holes PML-25-021, 035, and 038) are all positive supporting evidence for advancing this target. Power Metallic is currently assessing the logistically options for drilling into this anomaly, with the extension of PML-25-021, that sits at approximately 700m depth already, as a prime candidate for extension and testing of the BHEM panel. Power Metallic will update this target's advancement in the coming weeks.
