Power Metallic Mines Inc. Intercepts Lion Style Sulphides And Reports Exploration Results
Power Metallic Mines Inc. provided an exploration update of recent drilling and results of regional exploration from its fall drill program. Structural analysis of mineralization orientation from Lion Zone drill core, while confirming the dominant steep westerly plunge of the Lion Zone, also identified a shallow easterly plunge that appears to control the highest-grade zones within the Lion Zone. Currently four easterly trending structures have been identified. Follow-up holes are currently being drilled to establish the size of these two extensions to Lion. The first hole drilled on this target (PML-25-040) collared in the UM, so was in front of the Lion Zone stratigraphy. This established that there is an offset from the edge of the Lion Zone shifting geology to the north. Despite missing the Lion stratigraphy, below the UM the hole hit mineralization over 0.31m consisting of massive nickeliferous sulphides (2.42% Ni, 1.83 g/t Pd, 0.11% Cu) within a tonalite dyke. This mineralization is like the 'rafted' rip-up blocks seen at the Tiger deposit and indicate that a Ni-Pd-Cu deposit exists somewhere below the rafted block. Power Metallic has subsequently moved the drill collar further north to intersect the Lion stratigraphy structurally above the UM, and that hole is currently being drilled. The summer-fall 2025 regional exploration program targeted EM anomalies identified in the summer airborne survey, supplemented by surface mapping to identify favourable rock types for Ni-Cu mineralization. The EM survey produced more than 100 conductors. The initial drilling tested a variety of target areas to ascertain their prospectivity for Nisk and Lion style mineralization. The Power Metallic properties now cover over 330 km2, and to date only 16 holes have been drilled within an area approximately 40km x 10 km in size. Each area drilled is separated by several kilometers, and individual holes are generally hundreds of meters apart, so this initial program should be treated as a first reconnaissance of the regional property. Five target areas were tested based on EM anomalies, structural complexity, and proximity to potential ultra-mafic source rocks for Ni-Cu mineralization. All holes intersected sufficient semi-massive to massive sulphides to explain the EM conductors. Zone 1 - Hinge/Hydro Lands – PMX-25-001, 002, 015, 016: This area produced the best indications of potential Ni-Cu mineralization, and possible mobilized polymetallic (Lion Style). Mineralization is dominantly pyrrhotite within or proximal to high magnesium basalts (komatiitic) and gabbros, with local pyroxenite. All holes intersected highly anomalous arsenic and tungsten in, or proximal to, the high magnesium rocks. Local indications of polymetallic mineralization include Pd (up to 0.10 g/t), Pt (0.11 g/t) in hole PMX-25-015, and Au (0.36 g/t) in hole PMX-25-001 in the high Mg rocks. The four holes test an area of more than 2 km of strike along the prospective EM targets, and drill holes are hundreds of meters apart. The consistency of the alteration (As, W) and the rock types is encouraging, but the spacing of the holes is too large to provide any detailed modelling. Currently this area is being tested with follow-up drilling. . This intersection contains a foliation parallel stringer of visible gold. This unit has been identified in surface mapping over several kilometers and was also intersected in hole PMX-25-15 approximately 500m to the east of PMX-25-16. Relogging and resampling of this unit in both holes was incomplete and is being carried out now. The deep hole (PML-25-021X) targeting the Elephant BHEM plate also intersected this unit approximately 600m below PMX-25-016 with possible indications of mineralization. Assays are pending from this hole. Zone 2 – Nisk Far West – PMX-25-003: This target was an isolated EM conductor located approximately 10km west of the Nisk deposit. It failed to intersect prospective rock types or anomalous mineralization. Zone 3 – South Basin Margin West – PMX-25-004, 005, 006, 007, 008, 010: This target tested EM anomalies with complex structures and surface mapping support for hosting UM intrusions along the southern margin of the sedimentary-volcanic basin. The 6 holes were broadly scattered across approximately 5km of strike. All holes hit significant zones of sulphides. The anomalous mineralization consisted largely of Zn, Ag, Pd, Cu, indicative of a VMS deposit style signature. There were UM rocks intersected (11m in hole PMX-25-008 as example) but they contained no significant Ni-Cu-PGE anomalism. Zone 4 – Center Basin Tonalite – PMX-25-009, 011: The sulphide mineralization in these two holes appears to support a VMS style mineralization. There were no significant zones of UM rocks in these two holes. Zone 5 – South Basin Margin East – PMX-25-012, 013, 014: These three holes covered approximately 5km of strike along the southern boundary of the basin. Indications from the sulphides intersected suggest a VMS style with anomalous Zn, Cu, Ag. Drilling of the Elephant BHEM target (extension of hole PML-25-021) intersected pyrrhotite mineralization that did not appear to be Ni-Cu affinity. Follow-up BHEM has not established a strong off-hole conductor. The contact zone stratigraphy associated with the Lion deposit and the UM intrusion has been identified, but this contact did not contain UM. BHEM is currently being reassessed to develop new target vectors, and assay results on the contact zone are pending. The first hole at Tiger Deep was collared to drill between two BHEM generated conductor plates to refine the target area. Core is logged for lithology, mineralogy, and structural features, and sample intervals are delineated and tagged. Sampled core is mechanically sawn, and half-core is retained for future reference. GeoVector's QAQC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream with a stringent review of all results. QAQC and data validation was performed, and no material errors were observed. All samples were submitted to and analyzed at Activation Laboratories Ltd, a commercial laboratory independent of Power Metallic with no interest in the Project. Actlabs is an ISO 9001 and 17025 certified and accredited laboratories. Samples submitted through Actlabs are run through standard preparation methods and analysed using RX-1 (Dry, crush (< 7 kg) up to 80% passing 2 mm, riffle split (250 g) and pulverize (mild steel) to 95% passing 105 µm) preparation methods, and using 1F2 (ICP-OES) and 1C-OES - 4-Acid near total digestion + Gold-Platinum-Palladium analysis and 8-Peroxide ICP-OES, for regular and over detection limit analysis. Pegmatite samples are analyzed using UT7 - Li up to 5%, Rb up to 2% method. Actlabs also undertake their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration.
