HM PRESENTS RESULTS OF PHASE ONE EXPLORATION PROGRAM AT THE DEVIL’S DEN
PROJECT
March 19, 2025
Vancouver, B.C. – HM Exploration Corp. (“HM Exploration” or the “Company”) (CSE: HM) is pleased to
present the results of its Phase One exploration program at the Company’s Devil’s Den Project (the
“Project”) located west of Port Alberni, British Columbia.
“We have finished processing our data collected from the Phase One program at the Devil’s Den Project.”
said the Company’s Director & CEO Nicholas Rodway. “ The newly acquired data has produced high
resouloution 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 Devils Den. We look forward
to providing further updates as we get closer to the 2025 summer field season.”
Results of UAV Magnetic Survey
The results from a high-resolution unmanned aerial vehicle (UAV) magnetic survey recently completed by
the Company ha s 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. The figures below show the
geophysical results with the structural/lineament interpretation superimposed on both maps.

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 (Cui et al., 2017). 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 vo lcanic 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 sur vey aimed at generating a property -scale geochemical

dataset to better characterize and delineate the volcanic units within the Karmutsen Formation. The
updated geological interpretation and lithogeochemical sampling locations are presented in Figure 2.
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 en riched 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 altera tion has occurred. Magnetic survey data
corroborate this interpretation, highlighting this region as a magnetic low, consistent with
magnetite destruction during alteration.
• The northeastern sect ion is characterized by geochemically distinct primitive basaltic rocks,
enriched in Fe, Ti, V, Cr, and Mg. This geochemical signature indicates a relatively less
differentiated, Fe-Ti-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 es 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 mineralised zones were identified in the field and subsequently analysed using pXRF. In the northern
part of the property, a roadside outcrop exhibited copper oxide staining and returned elevated copper
values of up to 0.6% 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
mineralisation was identified. This location coincides with the MINFILE occurrence "J.F ”, and pXRF
analyses returned copper values of up to 4.3% Cu. Similar to the Dauntless West showing, this

mineralisation 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 mineralisation than previously recognised. Consequently,
these structural orientations will be the focus of targeted investigation in future exploration programs.

About the Phase One Program
The Phase One exploration program (the “Program”) consisted of the collection of 355 line-kilometers of
high-resolution unmanned airborne vehicle (UAV) geophysical magnetic data , prospecting of historical
copper and gold showings, and a property-wide litho -geochemical mapping study consisting of 101
Portable X-Ray Floresence readings. The UAV airborne geophysical survey was flown at a line spacing of
50 to 100 meters using a drone -deployed high-sensitivity potassium magnetometer. The sensor height
was maintained at 60 meters above the terrain using adva nced 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 is
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 Corp. (HM) 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 exploration project that consists of two contiguous claims totaling 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 po ssible anomalous gold, copper, and other minerals . Multiple high grade
mineral occurrences were uncovered including Cu values of up to 4.68% at surface (Devil’s Den NI 43-101,
Nov 2022). 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.
