HM PRESENTS RESULTS OF PHASE ONE EXPLORATION PROGRAM AT THE DEVIL'S DEN PROJECT

HM Exploration Corp. has released the results of its phase 1 exploration program at the Devil's Den project, located west of Port Alberni, B.C.

"We have finished processing our data collected from the phase 1 program at the Devil's Den project," said director and chief executive officer Nicholas Rodway. "The newly acquired data has produced high-resolution magnetic coverage over the project as well as the first-ever lithogeochemical map of the project. This new data will be invaluable for further evaluating the potenal at Devil's Den. We look forward to providing further updates as we get closer to the 2025 summer field season."

Results of UAV (unmanned aerial vehicle) magnetic survey

The results from a high-resolution UAV magnetic survey recently completed by the company have defined several high-priority, follow-up targets. These targets were further reinforced by integrating results from recent prospecting and lithogeochemical surveys conducted by the company. Of particular note, there are two zones that exhibit structural complexity, hydrothermal alteration, and elevated copper, zinc and nickel geochemistry. Additionally, the high-resolution UAV survey identified a series of previously unrecognized northwest-southeast-trending structures.

Lithogeochemical survey

The existing geological map covering the project area was published by the British Columbia Geological Survey in 2017 as Open File 2017-08. This map provides a generalized geological framework characterized primarily by two lithological units, which inadequately represent the area's true geological complexity. According to this previous interpretation, a north-northwest-trending lithological boundary divides the property, separating volcanic rocks of the Upper Triassic Karmutsen formation in the east from granodioritic and quartz dioritic intrusive rocks of the Jurassic Island Plutonic suite to the west.

Historical geological work and field observations within the project area and regionally have indicated substantial lithological variability within the Karmutsen volcanic sequence. To address this, the company initiated a comprehensive lithogeochemical survey aimed at generating a property-scale geochemical dataset to better characterize and delineate the volcanic units within the Karmutsen formation.

Integration of lithogeochemical data with results from a magnetic survey has highlighted distinct geochemical variations within the volcanic sequences, providing valuable insights for future exploration targeting. Key outcomes from this integrated analysis are as follows:

• The westernmost lithological unit, previously mapped as the granodiorite-quartz-diorite complex of the Island Plutonic suite, exhibits only subtle geochemical distinctions from adjacent volcanic units. This minor differentiation is interpreted to result from the evolved (relatively felsic) nature of the volcanic units in proximity to the intrusion. Field observations and detailed lithological descriptions were instrumental in refining the geological contact in the property's southern section.
• A unit located in the northwest part of the survey area, originally identified as granodioritic intrusive rocks, has been reassigned to the Karmutsen formation based on field evidence and lithogeochemical data. While typical Karmutsen volcanic rocks are enriched in magnesium, lithogeochemical analyses from this region revealed anomalous depletion in magnesium and calcium. In combination with field observations of silicification and oxidation, these geochemical signatures suggest moderate hydrothermal alteration has occurred. Magnetic survey data corroborate this interpretation, highlighting this region as a magnetic low, consistent with magnetite destruction during alteration.
• The northeastern section is characterized by geochemically distinct primitive basaltic rocks, enriched in iron, titanium, vanadium, chromium and magnesium. This geochemical signature indicates a relatively less differentiated, iron-and-titanium-rich tholeiitic basalt flow, corresponding spatially to a magnetic high in the geophysical survey.
• Although a regional north-south-trending fault is indicated in previous geological mapping, high-resolution magnetic data do not support the presence of a major fault structure in this orientation. Instead, the survey area exhibits a series of northwest-southeast-trending linear magnetic features interpreted as smaller-scale, potentially late-stage fault systems. Subtle geochemical differences are also observed, distinguishing chromium-enriched basaltic units from andesitic rocks toward the west.

This refined geological interpretation provides an enhanced framework to guide future exploration activities on the property.

Two mineralized zones were identified in the field and subsequently analyzed using pXRF (portable X-ray fluorescence). In the northern part of the property, a roadside outcrop exhibited copper oxide staining and returned elevated copper values of up to 0.6 per cent Cu. This occurrence corresponds to the historically documented Minfile West Dauntless showing and aligns with a northwest-trending structural feature identified in the geophysical interpretation. In the southwest portion of the property, a second outcrop hosting malachite mineralization was identified. This location coincides with the Minfile occurrence J.F., and pXRF analyses returned copper values of up to 4.3 per cent Cu. Similar to the Dauntless West showing, this mineralization is also associated with a northwest-trending structural lineament highlighted by the geophysical survey. The company's current working hypothesis suggests that northwest-trending structural features exert a stronger control on mineralization than previously recognized. Consequently, these structural orientations will be the focus of targeted investigation in future exploration programs.

About the phase 1 program

The phase 1 exploration program consisted of the collection of 355 line kilometres of high-resolution unmanned airborne vehicle geophysical magnetic data, prospecting of historical copper and gold showings, and a property-wide lithogeochemical mapping study consisting of 101 portable X-ray fluorescence readings. The UAV airborne geophysical survey was flown at a line spacing of 50 to 100 metres using a drone-deployed, high-sensitivity potassium magnetometer. The sensor height was maintained at 60 metres above the terrain using advanced terrain-following flight software. This approach leveraged modern UAV technology to acquire high-resolution magnetic data in a time- and cost-efficient manner. The flight plan was executed to cover historical and recently discovered, high-grade copper mineralization, as well as areas with limited historical exploration. The high-resolution data are currently being processed, and the results will be used to better define faults and structures that are presumed to act as fluid corridors for the mineralization observed at the surface.

About HM Exploration Corp.

HM Exploration is a Canadian mineral exploration company focused on the acquisition and development of mineral projects in Canada. The company is currently advancing the Devil's Den project, an exploration-stage project that consists of two contiguous claims totalling approximately 3,200 hectares, located on Vancouver Island, British Columbia. The company conducted an exploration program on the project in 2022, and four geochemical grids were established to identify possible buried mineralization in areas of possible anomalous gold, copper and other minerals. Multiple high-grade mineral occurrences were uncovered, including Cu values of up to 4.68 per cent at surface. The project hosts multiple historical adits with high-grade surface occurrences that remain undrilled. HM Exploration believes that there has been a lack of adequate modern exploration techniques applied to the project in the past, and this presents the opportunity for significant new discoveries.
