HM EXPLORATION COMMENCES OPTICAL & ACOUSTIC TELEVIEWER PROGRAM AT THE LEWIS PILLEY'S PROJECT

HM Exploration Corp. has contracted DGI Geoscience Inc. to conduct an optical and acoustic televiewer (OTV/ATV) program on the phase 1 drill holes at its Lewis Pilley's project in Newfoundland, Canada.

Highlights:

• DGI Geoscience has commenced an optical and acoustic televiewer (OTV/ATV) program on the phase 1 drill holes completed at the Clifford Jones (Bull Road) zone. The program will provide in situ structural measurements of planar and linear geological features.
• HM will use the structural measurements to support 3-D modelling and reconstruction of the VMS system, providing valuable insight into the orientation of the mineralized zones and potential vectors toward the system's original depositional source.
• Assays for holes PI-26-008 through PI-26-012 remain pending (see the company's news releases dated June 29 and July 7, 2026, for information on what was observed in these drill holes).

About the televiewer program (OTV/ATV)

Televiewers produce accurate and consistent oriented images of drill holes, allowing in situ structural measurements of both planar and linear geological features. Data can be visualized as 3-D virtual core or as 2-D unwrapped core, and structures can be measured very rapidly. Data are catalogued automatically and ready to import into 3-D modelling programs. Common features analyzed include veins, contacts, bedding/foliation, fractures/joints, faults, fold limbs and hinges.

About the Lewis Pilley's project

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

The project 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 project hosts a cluster of VMS (volcanogenic massive sulphide) 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 project 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 (VMS) 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 showing returned significant intersections, including 16.77 m of 1.84 per cent Cu and 3.05 m of 5.03 per cent Zn with 1.02 g/t Au (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 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 UAV 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.
