HM EXPLORATION EXPANDS LEWIS PILLEY'S PROJECT TO ~60 KM2

HM Exploration Corp. has expanded its land position through the staking of additional mineral tenure at the company's Lewis Pilley's project located in Newfoundland, Canada. The new tenure consists of 67 mineral claims encompassing an additional 17 square kilometres. The new tenure connects the northern and southern claim blocks, resulting in HM controlling the entirety of Pilley's Island.

"This marks the first time in recent history that the entirety of Pilley's Island has been consolidated under a single company," commented Nick Rodway, chief executive officer of HM Exploration. "With district-scale control now in place, we are focused on unlocking additional VMS-style targets across the property while continuing to aggressively drill the Clifford Jones zone, where several compelling targets have remained untested for years. We look forward to providing further updates as drilling progresses."

Highlights:

• Significant northern expansion of the Lewis project:
  • New tenure increases total land position at the Lewis project to approximately 60.25 square kilometres.
• The entirety of Pilley's Island is controlled by a single entity for the first time in recent history.
• Little systematic exploration has been conducted in the new tenure outside of the smaller-scale work completed by Brinco in the 1980s.
• Diamond drilling continues at Clifford Jones zone for a minimum of 2,500 metres.

Geology and mineralization

The property is located within the Notre Dame subzone of the Dunnage tectonostratigraphic zone. Of note, most of the property 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 Buchans 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 subseafloor replacement and exhalative varieties. The deposits are often flanked by extensive chlorite, sericite, silica, K-feldspar and epidote alteration often observed in bimodal-felsic volcanogenic massive sulphide 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 property's geology shares key characteristics with known volcanogenic massive sulphide districts in Newfoundland, including the past-producing Buchans, Ming and Rambler mines, supporting the exploration potential of the property.

About Lewis Pilley's project

The property is road accessible and situated approximately 25 kilometres east of the town of Springdale, approximately 55 kilometres southeast of Firefly Metals' Green Bay project and approximately 150 km from the Pine Cove mill and port by way of major roads.

The property has a long history of mining and exploration dating back to the late 1800s, when the Pilley's Island Pyrite Company Ltd. produced approximately 450,000 tonnes of massive pyritic ore from the Pilley's Island mine-Old mines (after Kerr, 1996).

The property hosts a cluster of VMS systems and prospects with demonstrated high-grade zinc-lead-copper-silver-plus-or-minus-gold intersections. Mineralization is typical bimodal-felsic VMS, with both massive sulphide and sulphide-clast breccias (Thurlow, 1996). The geological setting is directly analogous to the Buchans camp (Thurlow, 1996), and the presence of sulphide-clast breccias is a strong vector toward proximal massive sulphide lenses.

Most of the historic showings that fall within the extents of the property have not seen systematic exploration. 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.

About HM Exploration Corp.

The company is currently advancing its Lewis Pilley's project located in Newfoundland. The project encompasses a land area of approximately 60.25 square kilometres and hosts a cluster of volcanogenic massive sulphide systems and the historic Pilley's Island mine (approximately 450,000 tonnes of ore produced in the late 1800s). Historic drilling at the 3B-zone returned significant intersections, including 16.77 metres of 1.84 per cent copper and 3.05 m of 5.03 per cent zinc with 1.02 grams per tonne gold (Au Pell, 1989). The geological setting is directly analogous to the prolific Buchans camp, with multiple underexplored showings and strong potential for new discoveries.

In addition, the company holds a 100-per-cent interest in the Devil's Den project, an exploration-stage project consisting of two contiguous mineral licences encompassing approximately 3,200 hectares located west of Port Alberni, Vancouver Island, British Columbia. Exploration work completed in 2022 established four geochemical grids to identify possible buried mineralization, uncovering multiple high-grade occurrences including copper values up to 4.68 per cent at surface (Devil's Den NI 43-101, November, 2022). Phase 1 exploration completed in 2025 included high-resolution unmanned aerial vehicle magnetic surveying and a lithogeochemical program, which identified new structural targets and zones of elevated copper, zinc and nickel geochemistry. The project hosts multiple historical adits with high-grade surface occurrences that remain undrilled. HM believes a lack of adequate modern exploration has left significant discovery potential.

HM Exploration is committed to applying modern exploration techniques across its projects to unlock value in historically underexplored Canadian mining districts.
