HM Exploration Discovers New Blind Massive Sulphide Lens at Lewis Pilley's ProjectVANCOUVER, BC / ACCESS Newswire / 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:Holes six, seven, and eight have successfully intersected massive sulphide including a new blind discovery of massive sulphide mineralization at a drill core depth of ~155 m. See additional pictures of drill core below.Multiple mineralized intervals encountered displaying varying types of mineralization ranging from disseminated - semi-massive - massive sulphide, including:PI-26-006From 11.43 - 13.62m down-hole; 2.19m drilled length.PI-26-007From 7.00 - 28.00m down-hole; 21.00m drilled length.From 176.85 - 179.00m down-hole; 2.15m drilled length.PI-26-008From 15.00 - 28.00m down-hole; 13.00m drilled length. (Figure 1)From 163.45 - 170.22m down-hole; 6.77m drilled length.The identification of a second sulphide lens below the previously recognized upper debris-flow horizon supports the interpretation of a vertically extensive VMS system and provides a new exploration target for follow-up drilling.Assays pending; HM looks forward to providing updates as drilling continues."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 ex...
