Power Metallic Expands the Lion Zone - Exceptionally High Copper & Gold Grade Kicks on Deep Eastern Margin of Zone

Rhea-AI Summary

Power Metallic (PNPNF) announced significant drilling results from their Lion Zone winter 2025 campaign. The company reported exceptional findings from five drill holes, with standout intersections including:

A high-grade intersection in PN-25-096 yielding 13.54 g/t Au, 236.6 g/t Ag, and 1.08% Cu over 1.95 meters, and another notable result in PN-25-002 showing 7.78% Cu with significant precious metals content over 1.95 meters.

The drilling program revealed two key developments:

• Discovery of new mineralization within the ultra mafic layered intrusion, previously unseen in the Lion Zone
• Evidence of changing mineralization characteristics at depth, suggesting proximity to a potential Ni/Cu massive sulphide deposit

The company continues to expand the Lion Zone with nine holes still pending results. The winter 2025 campaign covers approximately 8km of favorable stratigraphy, including multiple zones: Lion, Nisk, Nisk East, and Tiger Zone.

Positive

• High-grade mineral discoveries: 13.54 g/t Au, 236.6 g/t Ag, 1.08% Cu over 1.95m in PN-25-096
• Successful expansion of Lion Zone with all 5 test holes hitting polymetallic mineralization
• Discovery of new mineralization in previously unexplored stratigraphic sequence
• Exceptional copper grades in eastern margin with up to 29.3% Cu in massive sulphides
• Multiple zones under exploration (Lion, Nisk, Nisk East, Tiger) covering 8km of favorable stratigraphy

Negative

• 13 holes still pending assay results, creating uncertainty in full exploration outcomes
• Narrowing of mineralization zones in deeper eastern side, missing lower grade disseminated mineralization

13.54 g/t Au, 236.6 g/t Ag, 1.08% Cu, 0.21g/t Pd – Cu EqRec¹ 12.64% over 1.95 m in PN-25-096

0.19 g/t Au, 50.68 g/t Ag, 7.78% Cu, 0.38g/t Pd, 1.09 g/t Pt and 0.20 Ni – Cu EqRec¹ 7.97% over 1.95 m in PN-25-002

TORONTO, April 30, 2025 /PRNewswire/ - Power Metallic Mines Inc. (the "Company" or "Power Metallic") (TSXV: PNPN) (OTCBB: PNPNF) (Frankfurt: IVV) is pleased to announce the return of 5 holes from the winter 2025 drilling campaign focused on the Lion Zone. The five holes (PN-25-096, 097, 100; and PML-25-001 and 002) were testing the down plunge extent of the Lion Zone, and a large off-hole EM (BHEM) anomaly detected in drill hole PN-24-093. All holes hit Lion style polymetallic mineralization (Table 1).

Power Metallic has been exploring multiple zones during the winter 2025 campaign, including the Lion Zone, Nisk Zone, Nisk East Zone, and Tiger Zone. The targets of the winter drilling extends over approximately 8km of strike of favorable stratigraphy. This news release is for Lion Zone drill holes (Figure 1).

Assay results are still pending from the winter 2025 program from extensional and definition drilling in the Lion area (9 holes remaining) and four holes from the Nisk deposit area.

LION ZONE DRILL RESULTS

The five holes reported in this release were testing the deeper plunge extent of the Lion Zone. Holes PN-25-096 and 097 intercepted wide zones (18.5 meters and 31.5 meters drill intercepts respectively) of lower grade disseminated mineralization in the structural hangingwall, as well as the narrower high grade zones characteristic of the Lion deposit (Table 1).

Of particular interest is high grade gold, silver, copper mineralization encountered within the ultra mafic (UM) layered intrusion (1.95 meters @ 13.54 g/t Au, 236.6 g/t Ag, 1.08% Cu, 0.21% Ni, 0.21 g/t Pd) in PN-25-096 (Table 1). This mineralization is in a stratigraphic sequence not previously seen to be mineralized at Lion (Lion occurs stratigraphically below the UM), and it appears to be a potential precursor to a more evolved polymetallic mineralization predicted in our exploration modelling.

In contrast holes PN-25-100 and PML-25-001 and 002 tested the deeper eastern side of the plunge on the Lion Zone. These holes are missing the lower grade disseminated mineralization, returning narrow high grade only. But the massive sulphide mineralization in these areas are very high grade and copper dominant. In particular, Holes PML-25-001 and 002 have sub-meter massive sulphides that graded 15% Cu and 29.3% Cu respectively, with significant Ni, Pd and Ag grades (Table 1).

These massive sulphide zones suggest a change in the character of Lion from the shallower drill intersections containing high precious metals (Pd, Pt, Ag, Au) that helped carry the CuEqRec¹ value. This change may represent possible closer proximity to a Ni/Cu massive sulphide deposit that is characteristic of other polymetallic districts in the world, but that have yet to be discovered at the Nisk project.

Terry Lynch, CEO of Power Metallic emphasized the high value of these results by stating, " "With each set of assays we are growing the Lion Zone. We are also still learning. We are defining some of the borders of the Zone even as we are advancing it at depth. The high grade hits here are exciting and we think meaningful clues on richer mineralized areas that are in close proximity. 

Figure 1 below shows a long-section with pierce points of the drill holes with assays reported in this news release. Included in Figure 1 are images of mineralization (assays pending) intersected in additional deep drill holes (PML-25-005 and 012a) that tested a BHEM anomaly projected along the plunge of the zone and suggesting a continuation of the high grade mineralization.
