HM Exploration lists on OTCQB Venture Market

VANCOUVER, British Columbia, June 10, 2026 (GLOBE NEWSWIRE) -- HM Exploration Corp. (“ HM Exploration ”, “ HM ” or the “ Company ”) ( CSE:HM ) ( FSE:X5H ) ( OTCQB:HMEXF ) is pleased to announce that the Company’s common shares have been approved for trading on the OTCQB Venture Market (the “ OTCQB ”) under the trading symbol “ HMEXF ”. The commencement of trading on the OTCQB was effective June 8, 2026. There will be no change to the Company’s trading on the Canadian Securities Exchange (“ CSE ”) under the symbol “ HM ” or on the Frankfurt Stock Exchange (“ FSE ”) under the symbol “ X5H ”.

Highlights: HM Exploration’s common shares approved for trading on the OTCQB Venture Market under the symbol “HMEXF”, effective June 8, 2026. The OTCQB listing provides U.S. retail and institutional investors with improved access to the Company’s common shares and enhances liquidity in the U.S. market. The Company has applied for eligibility for electronic clearing and settlement through the Depository Trust Company (“DTC”) in the United States.

The listing coincides with the Company’s active maiden drilling program at the Lewis Pilley’s Project in Newfoundland, Canada, where three of the first five holes have intersected massive, semi-massive and disseminated sulphide mineralization. “Listing on the OTCQB is an important milestone for HM Exploration as we enter the most active period in our Company’s history,” said Nick Rodway, CEO of HM Exploration Corp. “We are currently executing our maiden drill program at the Lewis Pilley’s Project, where three of our first five holes have successfully intersected sulphide mineralization. The OTCQB listing means U.S. investors now have direct and accessible participation in HM’s story at what we believe is a pivotal time for the project. We look forward to reporting assay results and continuing to advance our programs.” The OTCQB Venture Market is operated by OTC Markets Group Inc. in New York and is a recognized marketplace for entrepreneurial and development-stage U.S. and international companies.

The OTCQB provides U.S. investors with improved access to company information and electronic trading. The commencement of trading on the OTCQB is intended to expand the Company’s access to U.S. capital markets and provide an additional quotation venue for the Company’s common shares for U.S. broker-dealers and investors, subject to prevailing market conditions. The Company has applied for DTC eligibility, which will further facilitate electronic clearing and settlement of the Company’s common shares for U.S. investors.

A further news release will be issued upon the granting of DTC eligibility. About the Lewis Pilley’s Project The Project is road accessible and situated approximately twenty-five (25) km east of the town of Springdale, approximately fifty-five (55) km southeast of Firefly Metals’ Green Bay Project and approximately one hundred fifty (150) km from the Pine Cove Mill and Port by way of major roads.It 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 systems and prospects with demonstrated high-grade Zn-Pb-Cu-Ag+/-Au 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.

The Project encompasses a land area of ~60.25 km² and hosts a cluster of volcanogenic massive sulphide (VMS) systems and the historic Pilley’s Island Mine (~450,000 tonnes of ore produced in the late 1800s).

Historic drilling at the 3B-Zone returned significant intersections, including 16.77m of 1.84% Cu and 3.05m of 5.03% 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% interest in the Devil’s Den Project, an exploration-stage Project consisting of two contiguous mineral licences encompassing ~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% at surface (Devil’s Den NI 43-101, Nov 2022). Phase One 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.
