HM Exploration Begins Drilling at Lewis Pilley’s Project Targeting 16.6% Copper at Surface

Vancouver – HM Exploration Corp. (“HM Exploration” or “HM” or the “Company”) (CSE:HM) (FSE:X5H) is pleased to announce that it has 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*.    “The massive sulfide exposed at surface at the Zone exhibits high grade copper content and is extensive,” said Nicholas Rodway, CEO of HM Exploration. “The Zone we are currently drilling has not been historically tested. A 2016 trench uncovered the massive sulfide mineralization immediately southwest of prior drill holes, suggesting this zone was overlooked in earlier exploration campaigns. A high-grade, copper-rich intercept here would be transformative for the Company, particularly at this early stage of exploration. With recent exploration success in Newfoundland and increasing global focus on high-grade copper systems, we believe this represents a compelling opportunity for HM shareholders.” Highlights: * Outcrop samples referenced above were collected in 2025 by the Company as part of HM Exploration’s 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. Figure 1: Outcrop samples collected at the Zone in 2025 displayed impressive mineralization including both massive and disseminated chalcopyrite ± sphalerite, silver, gold, and lead*. Figure 2: Location map of the Project displaying historical showings/zones located on the Project. 2026 diamond drilling has commenced at the Zone. ** Historic intercept lengths have been converted from feet to meters and Ag/Au results have been converted from oz/t to g/t. About 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 a hundred fifty (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 1800’s when the Pilley’s Island Pyrite Company Ltd. produced approximately 450,000 tons of massive pyritic ore from the Pilley’s Island Mine-Old Mines (after Kerr, 1996). 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. Figure 3: Regional map of Newfoundland displaying the location of the Project and other significant mineral exploration and mining projects in Newfoundland – Canada. Geology & Mineralization 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.

About HM Exploration Corp. The Company is currently advancing the Devil’s Den Project, an exploration-stage property consisting of two contiguous claims totaling approximately 3,200 hectares on 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. The Company also controls the Lewis Pilley’s Project in Newfoundland, a 42.25 km² land package hosting a cluster of volcanogenic massive sulfide (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. HM Exploration is committed to applying modern exploration techniques across its projects to unlock value in historically underexplored Canadian mining districts.

HM Exploration Expands Pilley’s Island VMS District with Acquisition of Lewis Copper Tenure

~With historic drilling returning 1.84% copper over 16.7m~ Vancouver, March 11, 2026 – HM Exploration Corp. (“HM Exploration” or “HM” or the “Company”) (CSE:HM) is pleased to announce that it has entered into a property option agreement dated March 11, 2026 (the “Agreement”)  to acquire (the “Acquisition”) the option to earn a hundred percent (100%) interest in the Lewis Copper VMS Tenure located in Newfoundland, Canada (the “Tenure” or “Lewis Tenure”).  “This acquisition expands HM’s control of the Pilley’s Island VMS district,” said Nicholas Rodway, CEO of HM Exploration. “With promising historic copper drilling intercepts and multiple undrilled targets, we believe the district holds strong discovery potential. We are excited to hit the ground running for HM’s first ever diamond drill program.” Highlights: * The reported grades and volumes are historical in nature and are not considered current mineral resources or mineral reserves as defined by NI 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). The Company has not done sufficient work to classify these estimates as current, and a qualified person has not verified them. About the Tenure The Tenure consists of six (6) mineral licenses encompassing a total land area of 20 km2 making the total area of the land package approximately 42 km2. Collectively, the Tenure along with the Pilley’s Island Project will now be referred to as the “Lewis Pilley’s Project”. The Tenure is road accessible and situated approximately 25 km east of the town of Springdale, approximately 210 km from the town of Gander, 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 Tenure has a long history of mining and exploration dating back to the late 1800’s when the Pilley’s Island Pyrite Company Ltd. produced approximately 450,000 tons of massive pyritic ore from the Pilley’s Island Mine-Old Mines (after Kerr, 1996). The Lewis Pilley’s 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. Deep drilling has confirmed a large hydrothermal system with significant sulfide development. Most of the historic showings that fall within the extents of the new Tenure 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. Figure 1: Regional map of Newfoundland displaying the location of the Pilley’s Island Project and other significant mineral exploration and mining projects in Newfoundland – Canada. Geology & Mineralization The Tenure is located within the Notre Dame Subzone of the Dunnage Tectonostratigraphic Zone. Of note, most of the Tenure 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 Tenure’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 Tenure. From north to south the Tenure is underlain by: Lushes Bight Group – Lower Ordovician Composed of pillow basalts, pillow breccias, aquagene tuffs, massive basalt flows, flow breccias, and chlorite schist. Springdale Group – Silurian Terrestrial sequence of volcanics, pyroclastics, epiclastic to volcaniclastic sediments. Roberts Arm Group – Middle Ordovician The Roberts Arm Group, which hosts known mineralization, is complexly faulted and consists of an older tholeiitic terrane overlain by more calc-alkaline thrust slices. It is suggested that it represents an evolution from tholeiitic, back arc basalts to calc-alkaline intermediate to felsic volcanics deposited at about the time of continental collision in a neritic to littoral environment (after Bostock, 1988). Figure 2: Property map of the Lewis Pilley’s Project displaying historical showings/zones located on the Tenure. **Historic intercept lengths have been converted from feet to meters and Ag/Au results have been converted from oz/t to g/t. Prospective Areas 3B-Zone (additional claims) The 3B-Zone has been described as a massive sulfide zone containing Cu, Zn, Ag, Au (after Brinex, 1967). Brinco-Getty discovered the 3B-Zone during exploration carried out from 1981 to 1985. Historic estimates reference the zone to contain approximately 200,000 tons grading 3.00 – 4.00% Cu* (Epp, 1984). * The reported reserves are historical in nature and are not considered current mineral resources or mineral reserves as defined by NI 43-101. The Company has not done sufficient work to classify these estimates as current, and a qualified person has not verified them. Au Pell Resources Inc. conducted work in the 3B-Zone from 1987 to 1988 consisting of 1,949 meters of diamond drilling in eight (8) holes; mostly in the area of the 3B-Zone. This drilling intersected the extension of the 3B-Zone and some of the higher-grade intersections included: Clifford Jones (Bull Road) Extension Showing The Clifford Jones (Bull Road) Extension Showing consists of stockworks ‘feeder’ type mineralization with networks of veinlet and disseminated base metals sulphides including pyrite, chalcopyrite, galena, silver,

HM Exploration Acquires High Grade Copper VMS Project in Newfoundland

Vancouver, September 29, 2025 – HM Exploration Corp. (“HM Exploration” or “HM” or the “Company”) (CSE:HM) is pleased to announce that it has entered into an option agreement (the “Agreement”) dated September 25, 2025 with Great Atlantic Resources Corp. (the “Optionor”) to acquire a 100% interest in the Pilley’s Island Copper Project (the “Project”), located in Newfoundland, Canada (the “Acquisition”). Highlights: * The reported reserves are historical in nature and are not considered current mineral resources or mineral reserves as defined by NI 43-101. The Company has not done sufficient work to classify these estimates as current, and a qualified person has not verified them. About the Project The Project consists of eight (8) mineral licenses encompassing a total land area of 12.25km2 and is located in Notre Dame Bay, Newfoundland – Canada. The Project has a long history of mining and exploration dating back to the late 1800’s 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 is road accessible and situated ~25 kilometers east of the town of Springdale, approximately 210 kilometers from the town of Gander and ~150 kilometers from the Pine Cove Mill and Port by way of major roads. The Pilley’s Island Project hosts a cluster of Volcanogenic Massive Sulfide (VMS) systems and prospects with demonstrated high-grade Zn-Pb-Cu-Ag 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. Deep drilling has confirmed a large hydrothermal system with significant sulfide development. Further systematic exploration, particularly at depth and along strike of the Clifford Jones/Fragmental Zones is currently being planned. Many historic programs focused on shallow high-grade showings; deeper targets were only sporadically tested (Brinex, 1967). The Bull Road and Fragmental Zones were not systematically drilled along strike or down plunge (Hum, 1983). Geophysical anomalies adjacent to known zones were not followed up with drilling (Altius, 2001). Jasper Zone intersections (deep sulfides) were recognized but not fully explored with modern vectoring techniques (Altius/Inmet, 2003). Figure 1: Regional map of Newfoundland displaying the location of the Pilley’s Island project and other significant mineral exploration and mining projects in Newfoundland – Canada. Geology & Mineralization 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 low 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). Volcanogenic Massive Sulfide 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 property. From north to south the Project is underlain by: Lushes Bight Group – Lower Ordovician Composed of pillow basalts, pillow breccias, aquagene tuffs, massive basalt flows, flow breccias, and chlorite schist Springdale Group – Silurian Terrestrial sequence of volcanics, pyroclastics, epiclastic to volcaniclastic sediments Roberts Arm Group – Middle Ordovician The Roberts Arm Group, which hosts known mineralization, is complexly faulted and consist of an older tholeiitic terrane overlain by more calc-alkaline thrust slices. It is suggested that it represents an evolution from tholeiitic, back arc basalts to calc-alkaline intermediate to felsic volcanics deposited at about the time of continental collision in a neritic to littoral environment (after Bostock – 1988). Figure 2: Property map of the Pilley’s Island project displaying historical showings/zones located on the property. ** Historic intercept lengths have been converted from feet to meters and Ag/Au results have been converted from oz/t to g/t. Prospective Areas Bull Road – Clifford Jones Zone / Fragmental Showing The Bull Road – Clifford Jones Zone / Fragmental showings are a re-sedimented, polylithic breccia containing abundant high-grade Zn-Pb-Cu sulfide clasts similar to the breccia ores at Buchan’s. The showings, are significant and suggests the potential for an ore-grade deposit source (after Consolidated Morrison Ltd., 1979). ** Historic intercept lengths have been converted from feet to meters and Ag/Au results have been converted from oz/t to g/t. 3B – Zone Hole 42 Old Mines *The Project hosts the historic Pilley’s Island Mine, which operated during the 1890s and early 1900s. The Newfoundland and Labrador Department of Natural Resources reports historic estimated proven reserves of 1.159 million tonnes grading 1.23% Cu (referencing Grimley, 1968 as the source) in their Mineral Occurrence Database. These historical estimates of reserves are not reliable. The historical estimates are only relevant to the extent of identifying an area on the Project for research and possible future exploration. The key assumptions, parameters, and methods used to prepare the historical estimates are not known. A qualified person has not done sufficient work to classify the historical estimates as current resources or current reserves. A qualified person would need to complete sufficient work following CIM Best Practice Guidelines to upgrade or verify the historical estimates as current mineral resources or mineral reserves. This would almost certainly require additional exploration in the way of diamond drilling, trenching and / or underground work and corresponding sampling all of which must follow CIM Exploration Best Practice Guidelines. HM Exploration does not
