Power Metallic Mines Inc. pleased to announce the return of the final 11 holes from the winter 2025 drilling campaign focused on the Lion Zone (9 holes) and Nisk East (2 holes). The nine holes at lion (PML-25-005 to 013) were testing multiple areas of the Lion Zone, including the down plunge extent, shallow sub-crop projections, in-fill drilling of the Lion Zone, and testing of off-hole EM (BHEM) anomalies west of Lion. The nine holes reported in this release were testing the deeper plunge extent on the western side of the Lion Zone; shallow sub-cropping interpreted locations of the Lion Zone, and internal in-fill drilling to better define the heterogenous width and grade of the Lion Zone in preparation for a future mineral resource estimate.

Holes PML-25-005 and 012a were testing the down plunge extent of the western side of the Lion Zone. Both holes intersected substantial polymetallic zones indicating a potential shift to the west for the plunge of the high grade portion of the Lion zone. This plunge direction will be followed up by early drill holes in the spring/summer drill campaign starting in early June.

Holes PML-25-006 through 009a tested interpreted shallow sub-crop locations for the Lion Zone. The shallow areas of Lion were gaps in knowledge of the deposit. All holes hit low grade hanging-wall style mineralization but failed to intersect the high-grade zones encountered in deeper drill holes.

Hole PML-25-13 was specifically targeted on a wide gap in drill spacing that was interpreted as a relatively low grade portion of the Lion Zone. This hole intersected better than expected mineralization including 0.15 g/t Au, 3.73 g/t Ag, 1.48% Cu, 1.49 g/t Pd and 0.44 g/t Pt over 5.83 meters, effectively filling a hole in the projection of the Lion Zone. Two holes were targeted on areas east of the Nisk Deposit (MRE 2023), termed Nisk East in previous press releases.

Historical drilling in the area had given indications of possible Lion, or Lion-Nisk hybrid style mineralization through indicator minerals located in stratigraphic positions conducive for Lion style zones. Hole PMN-25-003 failed to intersect any significant mineralization, but hole PMN-25-004 hit Lion style mineralization on the stratigraphic footwall to the ultra-mafic sill, like Lion's location. Additional mineralization extended into the ultra-mafic with Ni-Cu Nisk style sulphide mineralization.

This discovery will be followed up by drilling in the spring/summer drill campaign and this success provides proof of exploration concepts along the untested target strike length between the Nisk and Lion zones.
