HM Exploration Commences Optical & Acoustic Televiewer Program at the Lewis Pilley’s Project

Vancouver, July 24, 2026 – HM Exploration Corp. (“HM Exploration”, “HM” or the “Company”) (CSE:HM)(FSE:X5H) (OTCQB:HMEXF) is pleased to announce it has contracted DGI Geoscience Inc. (“DGI”) to conduct an Optical and Acoustic Televiewer (OTV/ATV) program (the “Program”) on the Phase One drill holes at its Lewis Pilley’s Project (the “Project”) in Newfoundland, Canada. Highlights: 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 3D “virtual core” or as 2D “unwrapped core,” and structures can be measured very rapidly. Data is catalogued automatically and ready to import into 3D modelling programs. Common features analyzed include veins, contacts, bedding/foliation, fractures/joints, faults, fold limbs and hinges (https://www.dgigeoscience.com/imaging/). 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. 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 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 Company is currently advancing its Lewis Pilley’s Project located in Newfoundland. 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.

HM Exploration Confirms Significant Mineralization at Lewis Pilley’s Project; Intersects 23 Metres of 1.2% Cu, 1.7% Zn, 10.7 g/t Ag and 0.25 g/t Au

Vancouver, July 21, 2026 – HM Exploration Corp. (“HM Exploration”, “HM” or the “Company”) (CSE:HM)(FSE:X5H) (OTCQB:HMEXF) is pleased to announce assay results from the first seven (7) of twelve (12) drill holes from the Company’s Phase One drilling program (the “Program”) at its Lewis Pilley’s Project (the “Project”) in Newfoundland, Canada. Highlights: PI-26-007* PI-26-001* * All reported intervals represent drilled lengths. True widths of the mineralized intersections are currently unknown. “The intense mineralization we have visually observed in the first seven holes has now been confirmed by laboratory analysis, including high-grade intervals grading up to 2.45% Cu, 5.89 g/t Au and 92.2 g/t Ag in the lower lens and very extensive intervals in the upper lens,” said Nick Rodway, CEO of HM Exploration. “These assay results confirm that the Lewis Pilley’s Project hosts a polymetallic VMS system with excellent potential for expansion. With assays pending from holes eight to twelve, we are planning our EM survey in order to systematically design our Phase Two drilling program set to commence this fall.” The 2026 Phase One drilling Program was focused on evaluating the continuity of the mineralized system below known surface showings and along strike of the Clifford Jones (Bull Road) Zone (the “Zone”) to improve the Company’s understanding of the geological controls on mineralization. Assays have confirmed that the upper targeted copper-bearing debris flow contains significant mineralization over an interpreted strike length of approximately 60 m, from a total drill-tested length of approximately 135 m, within zones of massive to semi-massive sulphide through holes 1 and 2 as well as holes 5, 6, and 7 (Figure 1). Assay values from hole 7 also confirm that the lower mineralized sulphide lens contains significant mineralization within predominantly massive to semi-massive, and minor disseminated, sulphide mineralization (Figures 2 & 3). The assay results validate the Company’s geological interpretation that multiple stacked sulphide lenses are present within the Project’s Volcanogenic Massive Sulphide (“VMS”) system. Both the upper and lower mineralized zones are open along strike and down-dip. The mineralization from the upper zone is characterized by semi-massive to massive fragments of sulphide that have been fractured, transported, and chaotically mixed with varying types of volcanic rock. The fragments range from sun-rounded to angular, possibly indicating multiple transport events and reworking of these fragments through moderate to distal transport from the original deposition site. The source of the material is interpreted to be very nearby and may be supported by a stockwork vein system representing the feeder zone of the mineralization. The mineralization from the lower zone is characterized by more massive and coherent fragments of sulphide with less rounding and fracturing than observed in the upper zone. The more ‘intact’ nature of these fragments provides evidence that the new lower mineralized sulphide lens may represent debris deposited closer to the original hydrothermal vent system (Figure 4). Significant assay results from the first seven (7) drill holes of the Phase One drilling Program can be found below in Table 1.

HM Exploration Expands Newly Discovered Blind Massive Sulphide Lens at Lewis Pilley’s Project

Vancouver, July 7, 2026 – HM Exploration Corp. (“HM Exploration”, “HM” or the “Company”) (CSE:HM)(FSE:X5H) (OTCQB:HMEXF) is pleased to announce a visual drilling update from an additional four diamond drill holes completed as part of the Company’s Phase One drilling program (the “Program”) at its Lewis Pilley’s Project (the “Project”) in Newfoundland, Canada. The four holes in this press release represent an additional 1,115.60 metres for a total drilled meterage of 2,747.87m. Planning is already underway for a Phase Two drilling program in fall 2026 based on the encouraging visual observations. Figure 1: Drill core (lower zone) in hole PI-26-010 from 140.51 – 148.80m downhole. Detailed photo from core box, outlined in blue, highlighting sections of massive chalcopyrite + pyrite sulphide mineralization. See Table 2 for detailed visual descriptions. Highlights: “Holes 9 and 10 have successfully intersected the newly discovered lower massive sulphide lens extending the zone approximately 40 metres to the northwest at a vertical depth of only ~135 metres,” said Nick Rodway, CEO of HM Exploration. “These visual results continue to strengthen our geological model and reinforce the potential that we are vectoring toward the source of the mineralized system. With assays pending from all twelve Phase One drill holes, we are already planning a downhole EM survey followed by a Phase Two drilling program for fall 2026.” The 2026 Phase One Drilling program was focused on evaluating the continuity of the mineralized system below known surface showings and along strike of the Clifford Jones Zone (the “Zone”) to improve the Company’s understanding of the geological controls on mineralization (Figure 4). Visual observations from drilled holes indicate that the upper targeted copper-bearing debris flow was successfully intersected, with zones of alteration and massive to semi-massive sulphide mineralization observed in the drill core. Drill holes 9 and 10 have successfully intersected a lower mineralized sulphide lens that was previously undiscovered. Core samples have been submitted to the laboratory for analysis. Assay results will be released once they have been returned to the Company. Holes 9 and 10 intersected a wide range of massive, semi-massive and disseminated sulphide mineralization over the following drill core lengths*: Observations from drill core continue to support the interpretation that the new lower mineralized sulphide lens may represent debris deposited closer to the original hydrothermal vent system (Figure 5). Mineralization can be described as clast-dominated debris zones predominantly consisting of sub-angular to angular fragments of massive sulphide composed of Cpy + Py ± Sph ± Gn suspended in interstitial fine-grained disseminated sulphides (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. Matrix-dominated debris flow composed of fragments of sub-rounded to angular clasts of massive sulphide (Py + Cpy ± Sph ± Gn) and felsic ± mafic lithic fragments suspended in a matrix of fine-grained sulphide (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. More detailed classifications for individual intercepts are referenced in Table 2 below*. * The Company cautions that the presence of visible sulphides and visual estimates of mineral abundance are not indicative of grade and should not be considered a substitute for laboratory analysis. Assay results are pending. True widths of mineralized intersections are currently unknown. Figure 2: Drill core (upper zone) in hole PI-26-009 from 16.53 – 23.72m downhole.

HM Exploration Discovers New Blind Massive Sulphide Lens at Lewis Pilley’s Project

Vancouver, June 29, 2026 – HM Exploration Corp. (“HM Exploration”, “HM” or the “Company”) (CSE:HM)(FSE:X5H) (OTCQB:HMEXF) is pleased to announce that it has completed an additional three holes as part of the phase one drilling program (the “Program”) at the Company’s Lewis Pilley’s Project (the “Project”), located in Newfoundland, Canada. Figure 1: Drill core (upper zone) in hole PI-26-008 from 16.12 – 24.78m downhole. Detailed photo from core box, outlined in blue, highlighting sections of massive chalcopyrite + pyrite sulphide mineralization (A & B). See Table 2 for visual descriptions. The three holes in this press release represent an additional 544.27 metres for a total drilled meterage of 1,632.27m of a planned minimum 2,500 metres of diamond drilling. Highlights: “While we were expecting to see significant mineralization below the exposed massive sulphide horizon at the Clifford Jones trench, the intersection of the lower-lens came as a welcomed new exciting discovery” said Nick Ryan, Chief Geologist with HM Exploration Corp. “The discovery of a second mineralized lens demonstrates that the system is more extensive than previously recognized and supports the potential for multiple stacked sulphide horizons. We look forward to receiving laboratory assays back and delineating the extents of this new discovery with subsequent drilling.” Drilling was focused on evaluating the continuity of the mineralized system below known surface showings and along strike of Clifford Jones Zone (the “Zone”) to improve the Company’s understanding of the geological controls on mineralization (Figure 2). Visual observations from drilled holes indicate that the upper targeted copper-bearing debris flow was successfully intersected, with zones of alteration and massive to semi-massive sulphide mineralization observed in the drill core. Drill holes 7 and 8 have successfully intersected a new lower mineralized sulphide lens that was previously undiscovered. The lower-lens appears more massive indicating that the geometry of this lens may assist with vectoring towards the source vent(s) as depicted in Figure 3. Core samples have been submitted to the laboratory for analysis. Assay results will be released once they have been returned to the Company. All three holes from this release intersected a wide range of massive, semi-massive and disseminated sulphide mineralization over the following drill core lengths*: Mineralization can be described as clast-dominated debris zones consisting of sub-angular to angular fragments of massive sulphide (~85% of intercept) composed of Cpy + Py ± Sph ± Gn suspended in interstitial fine-grained disseminated sulphides (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. Matrix-dominated debris flow composed of fragments of sub-rounded to angular clasts of massive sulphide (Py + Cpy ± Sph ± Gn) and felsic ± mafic lithic fragments suspended in a matrix of fine-grained sulphide (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. More detailed classifications for individual intercepts are referenced in Table 2 below*. * The Company cautions that the presence of visible sulphides and visual estimates of mineral abundance are not indicative of grade and should not be considered a substitute for laboratory analysis.

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.

HM Exploration Drills Massive Sulphide at Lewis Pilley’s Project

Vancouver, June 4, 2026 – HM Exploration Corp. (“HM Exploration”, “HM” or the “Company”) (CSE:HM)(FSE:X5H) is pleased to provide an update on the first five holes of the phase one drilling program (the “Program”) at the Company’s Lewis Pilley’s Project (the “Lewis Project”, the “Property”), located in Newfoundland, Canada. The first five holes of the maiden drilling program represent 1,088 metres of a planned minimum 2,500 metres of diamond drilling. Highlights: “The goal of our first drill program is to test the VMS-style debris flow mineralization visible at surface,” said Nick Rodway, CEO of HM Exploration Corp. “Three of the first five holes successfully intersected zones of massive, semi-massive and fine-grained disseminated sulphide mineralization, including sizeable angular chalcopyrite-bearing clasts. Surface grab samples from this area have returned values of over 16% copper, and we are encouraged to see similar mineralization now intersected in drilling. The angular nature of the mineralized clasts may indicate relatively limited transport from their source and is consistent with proximity to a hydrothermal vent environment.” Drilling was focused on evaluating the continuity of the mineralized system below known surface showings and along strike of Clifford Jones Zone (the “Zone”) to improve the Company’s understanding of the geological controls on mineralization. Visual observations from the initial five holes indicate that the targeted copper-bearing debris flow was successfully intersected, with zones of alteration and massive to semi-massive sulphide mineralization observed in the drill core. Core samples for the first five holes have been submitted to the laboratory for analysis. Assay results will be released once they have been returned to the company. Three of five holes intersected a wide range of massive, semi-massive and disseminated sulphide mineralization over the following drill core lengths*: Mineralization can be described as clast-dominated debris zones consisting of sub-angular to angular fragments of massive sulphide (~85% of intercept) composed of Cpy + Py ± Sph ± Gn suspended in interstitial fine-grained disseminated sulphides (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. Matrix-dominated debris flow composed of fragments of sub-rounded to angular clasts of massive sulphide (Py + Cpy ± Sph ± Gn) and felsic ± mafic lithic fragments suspended in a matrix of fine-grained sulphide (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. More detailed classifications for individual intercepts are referenced in Table 2 below*. * The Company cautions that the presence of visible sulphides and visual estimates of mineral abundance are not indicative of grade and should not be considered a substitute for laboratory analysis. Assay results are pending.    Figure 1: Plan map of 2026 diamond drilling at the Clifford Jones (Bull Road) Zone.

HM Exploration Expands Lewis Pilley’s Project to ~60 km²

Vancouver, May 25, 2026 – HM Exploration Corp. (“HM Exploration”, “HM” or the “Company”) (CSE:HM)(FSE:X5H) is pleased to announce that it has expanded its land position through the staking of additional mineral tenure (the “new tenure”) at the Company’s Lewis Pilley’s Project (the “Lewis Project” and together with the new tenure, the “Property”), located in Newfoundland, Canada. The new tenure consists of 67 mineral claims encompassing an additional 17 km². 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, CEO of HM Exploration Corp. “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: Figure 1: HM Exploration’s tenure on Pilley’s Island with an additional 67 mineral claims staked bringing the total land position to ~60.25 km². Geology & 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 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 Property’s geology shares key characteristics with known Volcanogenic Massive Sulfide (“VMS”) districts in Newfoundland, including the past producing Buchans, Ming and Rambler Mines, supporting the exploration potential of the Property. Figure 2: Regional map of Newfoundland displaying the location of the Property and other significant mineral exploration and mining projects in Newfoundland – Canada. About Lewis Pilley’s Project The Property 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 (Please see Figure 2). 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).

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*.

Each LIFE FT Unit is comprised of one common share in the capital of the Company (a “LIFE FT Share“) and one common share purchase warrant (a “LIFE Warrant“). Each LIFE FT Share was issued as a “flow-through share” within the meaning of subsection 66(15) of the Income Tax Act (Canada). Each LIFE Warrant is exercisable to acquire one additional common share of the Company at an exercise price of $0.75 for a period of twenty-four (24) months from the date of closing. Subject to compliance with applicable regulatory requirements and in accordance with National Instrument 45-106 – Prospectus Exemptions (“NI 45-106“), the LIFE Offering was made to purchasers resident in Canada pursuant to the listed issuer financing exemption under Part 5A of NI 45-106 (the “Exemption“). The securities issued under the Exemption are not subject to a hold period in accordance with applicable Canadian securities laws. The Company intends to use the gross proceeds of the LIFE Offering to advance the exploration of the Company’s Lewis Pilley’s Project located in Newfoundland. The proceeds from the sale of the LIFE FT Units will be used to incur exploration expenses that qualify as “Canadian exploration expenses” as defined in subsection 66.1(6) of the Income Tax Act (Canada) (the “Tax Act”) and “flow-through critical mineral mining expenditures” as defined in subsection 127(9) of the Tax Act for purposes of the critical mineral exploration tax credit. Such expenses will be incurred on or before December 31, 2027, and renounced to the subscribers with an effective date no later than December 31, 2026. The securities described herein have not been and will not be registered under the United States Securities Act of 1933, as amended, or any U.S. state securities laws, and may not be offered or sold in the United States absent registration or available exemptions from such registration requirements.

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.
