HARFANG AND SOQUEM MAKE HIGH-GRADE
GOLD DISCOVERIES AT MENARIK WEST, QUÉBEC
Montreal, October 29, 2025 – Harfang Exploration Inc. (TSX-V: HAR) (“Harfang”) and SOQUEM Inc.
(“SOQUEM” and together the “Companies”) announce multiple high-grade gold discoveries from their joint
summer 2025 exploration program at Harfang’s wholly-owned Menarik West Property (the “Property”), located
in Eeyou Istchee James Bay, Québec (see Figure 1).
HIGHLIGHTS
§ Discovery of six (6) gold showings, two (2) gold and silver showings, and one (1) copper showing.
§ Top three grab samples returned 55 g/t Au, 35 g/t Au, 5 g/t Au; in total eight (8) grab samples returned
over 2 g/t Au.
§ Additional gold-bearing and altered monzonites found within and outside the known Pierre Zone that
will likely serve as a driver for future exploration.
§ Gold discoveries on recently staked claims in the southwestern part of the Property.
Rick Breger, President and CEO of Harfang, commented, “Harfang continues to punch above its weight. This
is the second exploration program that has led to a gold discovery in the last six months. Here in Quebec, our
partner, SOQUEM, deserves abundant praise. Their deep expertise in exploration and Quebec geology has
been invaluable. This summer marked a major step forward for Menarik West—we advanced into previously
unexplored ground and made high-grade gold discoveries both within and beyond the Pierre Zone.”
“One of the most exciting developments is the presence of more altered monzonites outside the known Pierre
monzonite. Our early interpretation is that these monzonites could host the core value of the deposit, with the
veins and stockwork acting as high-grade sweeteners. With two bonanza-grade gold veins, widespread altered
monzonites, and the discoveries on recently staked ground, both Harfang and SOQUEM are already seeing the
benefits of continued exploration investment.”
Summer Program Overview
On July 29, 2025, Harfang and SOQUEM signed a definitive option and joint venture agreement (the
“Agreement”), giving SOQUEM the option to earn a 50% interest in the Property by funding $3,000,000 of
exploration expenses and paying Harfang $200,000 in cash, over a three-year period.
In August 2025, the Companies completed a 20-day exploration program at Menarik West. The program,
funded entirely by SOQUEM, was designed to evaluate multiple underexplored structural corridors and
intrusive contacts outside of the main Pierre showing. To date, most of the exploration efforts have been
concentrated on the Pierre intrusive center (the “Pierre Zone”), which continues to remain the key target at
Menarik West.
The summer exploration program identified multiple new showings (see Table 1 & Figure 2), both intrusion-
hosted and vein-type, confirming that the gold-bearing system at Menarik West extends well beyond the known
Pierre Zone. This is highlighted by the identification of additional intrusion-hosted mineralization north and
northeast of the Pierre Zone, pointing to complementary gold targets (see Figure 3).

overall grade of underlying mineralization.
Intrusion-Hosted Mineralization
The Adrian discovery returned 3.67 g/t Au from a porphyritic monzonite altered by chlorite, sericite, hematite,
and disseminated pyrite, and cut by quartz-carbonate stockwork. The alteration and mineralization styles are
analogous to those of the Pierre Zone where Harfang intersected 1.15 g/t Au over 47 m in hole LMN-23-017
(see press release dated May 11, 2023). Located approximately 300 metres northwest of LMN-23-017, the
Adrian discovery reinforces the potential for a larger, continuous intrusion-related gold system along the eastern
contact of the Pierre Zone (see Figure 3).
Additional sampling of a series of intermediate stocks and dikes, both within and outside the Pierre Zone,
yielded the presence of gold associated with disseminated sulphides and alteration facies in chlorite ± hematite,
sericite, and quartz. These mineralized zones are consistent with induced polarization (“IP”) chargeability axes.
Pierre and the newly identified gold-enriched intrusions share similar magmatic signatures (sanukitoid-type),
which are analogous to the intrusive rocks at major gold deposits including Canadian Malartic and the Kirkland
Lake gold camp, both located in the heart of the Abitibi Gold Belt.
High-Grade Vein-Type Discoveries
The Merlin and Jorge discoveries, both located in the central area of the Property, represent the vein-type gold
discoveries with the highest grades from the summer exploration program.
At Merlin, a grab sample returned 55.40 g/t Au and 106 g/t Ag from a quartz-carbonate vein with approximately
10% disseminated pyrite, and hosted in a chlorite- and ankerite-altered monzonite at the northern margin of
the Pierre Zone. The Merlin discovery is spatially coincident with an IP chargeability axis.
At Jorge, a grab sample returned 34.60 g/t Au from a quartz-carbonate vein hosted in a gabbro dyke along an
east-west trending shear zone. Visible gold was observed (see Figure 4).
New Prospective Ground
In March 2025, Harfang acquired an additional 26 exclusive exploration rights (“EERs”) by map designation on
the southwestern part of the property. As part of the summer exploration program, the Companies conducted
a first-pass prospecting campaign on these EERs, which led to the discoveries of Missi and Vincent, returning
4.17 g/t Au and 2.05 g/t Au, respectively. Both discoveries are associated with quartz veining in NE-trending
shear zones, which further connect eastward with prospective structural corridors.
Follow-up work on the 2022 discoveries in the eastern part of the Property, along major NE-trending faults, led
to the recognition of three additional zones of interest: Gil (4.92 g/t Au and 55.8 g/t Ag), Cox (2.15 g/t Au), and
Oswald East (0.76% Cu, 0.33 g/t Au, 41.2 g/t Ag). These showings consist of laminated quartz-carbonate veins
associated with gabbro and iron formation within a three-kilometre-long NE-trending structural corridor that
extends beyond previously tested zones.
About Menarik West
The Menarik West Property consists of 332 EERs, covering 171 km2. The Property is accessible via the Billy-
Diamond Highway that cuts across the Property, at kilometre 500 from the town of Matagami. The closest town
is Radisson, located approximately 50 km to the north. Three major powerlines pass through the Property.
Menarik West has been intermittently explored since the early 2000s with drilling primarily focused on the Pierre
Zone. As a result, much of the property remains underexplored. Historic and recent drilling, including Harfang’s
2023 program, demonstrated the presence of low-grade mineralized envelopes, highlighted by the Pierre Zone
which returned 0.89 g/t Au over 68.25 metres (drill hole 1404-03) and 1.15 g/t Au over 47 metres (drill hole
LMN-23-017). Mineralization consists of brecciated and highly altered monzonite with zones of sericitization,
silicification, and pyrite along with quartz-carbonate veins and stockwork.
Sampling Protocols and Quality Control
Each rock sample collected in the field was identified, securely bagged and transported to ActLabs laboratories
(Val-d’Or, Québec), a certified commercial laboratory, to be analyzed for gold and a suite of other chemical
elements. These samples were prepared using the RX1 method and analyzed by ICP-OES & ICP-MS (UT-6M)
for 49 elements, and by fire assay on 30-gram fractions with atomic absorption finish for gold, following a 4-
acid (near-total) digestion. Overrange assays for gold (>10 g/t Au) were reanalyzed by fire assay on 30-gram
fractions with a gravimetric finish. A strict QA/QC procedure was implemented, with one certified reference
material (CRM) and one blank sample inserted into the sample stream for every batch of 50 samples.
