HM Exploration Commences Borehole & Surface EM Surveys at Lewis Pilley's

About this update from Hm Exploration Corp.

VANCOUVER, BC / ACCESS Newswire / August 17, 2026 / HM Exploration Corp. ("HM Exploration", "HM" or the "Company") (CSE:HM) (FSE:X5H) (OTCQB:HMEXF) is pleased to announce it has contracted Crone Geophysics ("Crone") and commenced borehole and surface Time-Domain Electromagnetic (TDEM) surveys (collectively the "Surveys") at its Lewis Pilley's Project (the "Project") in Newfoundland, Canada. "The ongoing EM surveys will be instrumental in refining targets for our Phase Two drill program," said Nick Rodway, President and CEO of HM Exploration. "Phase One drilling confirmed continuity within both the Upper and Lower lenses. The borehole and surface EM data will help us evaluate their potential extensions and identify additional conductive targets that may represent massive sulphide mineralization. We look forward to reporting the results once the surveys and interpretation are complete." Highlights: The goal of the Survey is to identify potential extensions of known mineralized zones and additional conductive targets surrounding the Phase One drilling at the Clifford Jones (Bull Road) Zone. TDEM is particularly effective for Volcanogenic Massive Sulphide (VMS) exploration because many volcanogenic massive sulphide deposits contain significant concentrations of conductive sulphide minerals, which can produce a measurable electromagnetic response. The data from the survey will provide valuable information that will assist with drill hole planning for the Phase Two drill program that is planned to take place in late 2026. About the TDEM Surveys Crone Geophysics is actively conducting borehole TDEM surveys in drill holes from the Phase One drill program completed in May 2026 at the Clifford Jones (Bull Road) Zone. Upon completion of the borehole surveys, Crone will then execute a surface survey consisting of approximately 13-line kilometres covering approximately one square kilometre encompassing and expanding on ground surrounding the Phase One drill holes (Figure 1). Time-Domain Electromagnetics (TDEM) is a proven geophysical technique widely used in mineral exploration to identify and characterize electrically conductive zones in the subsurface. In VMS exploration, TDEM is particularly effective because many volcanogenic massive sulphide deposits contain significant concentrations of conductive sulphide minerals, which can produce a measurable electromagnetic...
