HM Exploration Corp. Begins Drilling at Lewis Pilley’s Project Targeting 16.6% Copper at Surface
HM Exploration Corp. had commenced drilling at the Clifford Jones (Bull Road) Trench Zone (the “Zone”) at the Company’s Lewis Pilley’s Project (the “Project”) located in Pilley’s Island, Newfoundland. The drilling program (the “Program”) is designed to test high-grade copper mineralization directly beneath surface samples collected in 2025 that returned up to 16.6% copper. A 2016 trench uncovered the massive sulfide mineralization immediately southwest of prior drill holes, suggesting this zone was overlooked in earlier exploration campaigns. Highlights: Two thousand five hundred (2,500) meters minimum diamond drilling program underway at the Zone. Drilling targeting high-grade mineralization beneath surface samples grading up to 16.56% Cu. 2025 outcrop grab samples taken by the Company at the Zone returned: Sample 181000 returned 6.79% Cu, 2.99% Zn, 22.50 g/t Ag, and 0.64 g/t Au. Sample 181001 returned 4.46% Cu, 2.63% Zn, 22.00 g/t Ag, and 0.53 g/t Au. Sample 181002 returned 16.56% Cu, 1.68% Zn, 18.60 g/t Ag, and 0.80 g/t Au. Sample 181003 returned 5.89% Cu, 27.20 g/t Ag, and 0.38 g/t Au. Sample 181007 returned 8.08% Cu, 17.50 g/t Ag, and 0.18 g/t Au. Historic drilling conducted by Brinco-Getty and Brinex in the peripheral area produced assay values up to: BBF-27: 3.05m @ 0.93% Cu, 0.89% Pb, 3.51% Zn, 27.68 g/t Ag. PI-83-01: 7.35m @ 0.66% Cu, 0.51% Pb, 3.41% Zn, 10.57 g/t Ag. PI-83-07: 2.49m @ 0.70% Cu, 0.22% Pb, 0.74% Zn, 6.53 g/t Ag. * Outcrop samples referenced above were collected in 2025 by the Company as part of HM Explorations due diligence process prior to entering into the agreement to acquire the Project. Historic intercept lengths have been converted from feet to meters and Ag/Au results have been converted from oz/t to g/t. Outcrop samples collected at the Zone in 2025 displayed impressive mineralization including both massive and disseminated chalcopyrite ± sphalerite, silver, gold, and lead. The Project hosts a cluster of Volcanogenic Massive Sulfide (“VMS”) systems and prospects with demonstrated high-grade Zn-Pb-Cu-Ag+/-Au intersections. Mineralization is typical bimodal-felsic VMS, with both massive sulfide and sulfide-clast breccias (Thurlow, 2001). The geological setting is directly analogous to the Buchans camp (Thurlow, 1996), and the presence of sulfide-clast breccias is a strong vector toward proximal massive sulfide lenses. Most of the historic showings that fall within the extents of the Project have not seen systematic exploration recently or historically. Many of the historic drill holes were shallow and drilled in a vertical orientation limiting the geological knowledge of the extents of the underlying lithology and mineralization. Work is being planned to validate historic assay results as well as collect new data from the 3B-Zone, Clifford Jones (Bull Road) Extension, Bouzanne Shaft, Henderson, Mansfield and Pilley’s Cove Showings. The Project is located within the Notre Dame Subzone of the Dunnage Tectonostratigraphic Zone. Of note, most of the Project is underlain by Ordovician submarine volcanic rocks of the Roberts Arm Group which is regionally identified as part of a mature arc sequence referred to as the Buchans-Roberts Arm Belt that also hosts the historic Buchan’s mine (after Dunning et. Al., 1987). Mineralization occurs as lower grade (Spencer’s Dock); medium grade (Old Mines); and high grade (3B-Zone/Clifford Jones) deposits that are of both sub-seafloor replacement and exhalative varieties. The deposits are often flanked by extensive chlorite, sericite, silica, K-feldspar and epidote alteration often observed in bimodal-felsic VMS systems. The Spencer's Dock area displays sericite/silica alteration that generally increases in intensity near mineralized zones, while the 3B/Old Mine areas display sericite/silica alteration that is abundant but less widespread and is more intense when proximal to mineralized zones (after Kerr, 1996). VMS deposits are a globally significant source of copper, zinc, lead, silver, and gold. The Project’s geology shares key characteristics with known VMS districts in Newfoundland, including the past producing Buchans, Ming and Rambler Mines supporting the exploration potential of the Project.
