HARFANG ANNOUNCES POLYMETALLIC DISCOVERIES
AND UP TO 6.84% Cu (GRAB) AT MENARIK EAST, QUEBEC
MONTREAL, November 26, 2025 - Harfang Exploration Inc. (TSX.V: HAR) (“Harfang” or the “Company”) is
pleased to announce the results from summer exploration at its wholly-owned Menarik East project (the
“Project”) located in Eeyou Istchee James Bay, Quebec (see Figure 1). The Company has made discoveries of
multiple polymetallic mineralized showings confirming the presence of a large critical and strategic minerals
(“CSM”) domain associated with the Menarik Igneous Complex (the “MIC”).
HIGHLIGHTS
§ Exploration highlights include: 8.57% CuEq (6.84% Cu, 0.99 g/t Au), 3.39% CuEq (2.24% Cu, 0.57 g/t
Au), and 1.53% CuEq (0.73% Cu, 0.44% Ni, 0.17 g/t Au) in grab samples, as well as the discovery of
additional copper and nickel showings that strengthen the potential of the mineralized footprint at
Menarik East.
§ The Company has defined two highly prospective domains: the West Domain which demonstrates
strong copper-nickel potential, and the Central Domain characterized by enriched nickel–PGE–
chromium.
§ Analogous to Ontario’s Ring of Fire with both deposits sharing similar geology (ultramafic rocks with
felsic intrusions), similar polymetallic mineralization (Cu, Ni, PGEs, Cr, Au), and a similar age (approx. 2.7
billion years old).
Rick Breger, President and CEO of Harfang, commented, “Menarik East is shaping up to be a standout asset in
our portfolio and a genuinely compelling opportunity within the broader James Bay emerging critical-minerals
corridor. The scale of the intrusive complex, the continuity we’re seeing within the chromite -PGE-bearing
horizons, and the strong comparisons to world-class systems in Ontario’s Ring of Fire give us confidence that
this project has the geological ingredients to support a major system. Our 2025 summer program resulted
in 8.57% CuEq, 3.39% CuEq, and 1.53% CuEq, which reinforces our conviction that Menarik East could be an
emerging polymetallic camp. The momentum building on this project is significant, and we are committed to
driving it forward aggressively as we refine and prioritize targets for the next phase of work.”
“Geologically, what makes Menarik East so compelling is how closely it resembles the major discoveries in
Ontario’s Ring of Fire. The historic chrome- and PGE-rich layers show similarities to the Black Thor and Blackbird
zones, while the nickel–copper areas we’ve identified share several important traits with the Eagle’s Nest
deposit. In simpler terms, we’re seeing a similar geological and mineralized setting that helped drive one of the
most important critical-minerals discoveries in Canada over the last two decades. These parallels, combined
with the strong results from our summer program, suggest that Menarik East has the potential to deliver both
chromium-PGE and nickel–copper discoveries within the same large intrusive system which is a rare and highly
attractive opportunity for a project at this stage.”
Summer Program Overview
The Company carried out a summer exploration campaign designed to achieve two key objectives: (i) verify
historical results demonstrating significant copper and nickel mineralization, and (ii) evaluate new high-priority
CSM targets.
The summer exploration program has successfully confirmed the presence of C u, Ni, PGE, and Cr
mineralization, both within and along the margins of the MIC. In addition, Harfang has outlined new copper
and nickel showings, extending from known systems and closely associated with ultramafic contacts and shear
structures (see Figures 2 and 3). These results further strengthen the potential of the mineralized footprint at
Menarik East.
In concert with the historical compilation work, Harfang’s 2024 and 2025 exploration activities have defined two
polymetallic domains that, together, cover a 4 km2 area: the “West Domain”, located to west of the MIC, which
demonstrates strong copper–nickel potential, and the “Central Domain”, located within the heart of the CIM,
that is characterized by enriched nickel–PGE–chromium. At the West Domain, assay results are highlighted by
8.57% CuEq and 3.39% CuEq, and at the Central Domain, assay results are highlighted by 0.91% NiEq and
0.74% NiEq (see Table 1).
The project area hosts a historical resource of 1.0 Mt grading 0.38% Ni and 0.15% Cu, and 6.19 Mt grading
7.69% Cr₂O₃ with 398 ppb Pd and 105 ppb Pt (see Historic Resource Disclosure below), underscoring the
significant upside potential and supporting the Company’s view that Menarik East represents a significant
opportunity.
The West Domain
The West Domain measures 1.5 x 1.0 km and is defined by a dominant volcano-sedimentary unit, with ultramafic
intrusions along an east-southeast-trending corridor. The distribution of the polymetallic mineralization is
controlled by branches of ultramafic and mafic intrusions as well as by east-southeast-trending deformation
zones and faults. The latter also affects sedimentary rocks and intermediate to mafic volcanics. The orientation
of the deformation structures coincides with that of the Menarik Lake fault.
Within the generally serpentinized and talc-bearing deformed ultramafics, mineralization is typically Cu-Ni, with
grab samples returning 6.84% Cu and 0.99 g/t Au (8.57% CuEq), 2.24% Cu and 0.57 g/t Au (3.39% CuEq),
along with 0.73% Cu, 0.44% Ni and 0.17 g/t Au (1.53% CuEq). In sediments and volcanic rocks, grades reach
up to 1.43% Zn and 64.5 g/t Ag accompanied by Cu-Ni anomalies.
Sulphides, disseminated chalcopyrite, pyrrhotite, and pyrite, form clusters in ultramafic intrusions or near
contacts in the volcano-sedimentary host rock. Mineralization is also associated with quartz veins in shears
hosted in fractured and sericite-altered quartzite and volcanics.
The Central Domain
The Central Domain measures 2.5 x 1.0 km and is situated at the core of the MIC. It has demonstrated chromium
and PGE mineralization and shows potential for nickel mineralization. Surface samples of serpentinized
peridotite with magnetite, containing pyrrhotite and pentlandite, returned values of 0.18% Ni, 0.49 g/t Pd and
0.12 g/t Pt (0.37% NiEq), 0.20% Ni, and 0.15% Ni.
In addition, grab samples from 2024 returned 11.20% Cu, 0.25% Ni and 0.12 g/t Au (11.67% CuEq), 2.11% Cu
and 2.12 g/t Au (4.63% CuEq), along with 1.72% Cu, 0.24% Ni and 0.14 g/t Au (2.22% CuEq), in strongly
structurally-controlled serpentinized peridotites with disseminated pyrite-pentlandite-chalcopyrite (see press
release dated October 17, 2024). High copper grades in the central domain coincide with shear zones and, as
in the West Domain, appear to form a network connecting to the Menarik Lake Fault.

Coordinates are presented in NAD83 UTM Zone 18. CuEq and NiEq values are calculated using 100% recoveries and the following metal prices and cut-
off grades, respectively: US$4.9/lb Cu and 500 ppm, US$6.7/lb Ni and 1,000 ppm, US$4,000/oz Au and 0.10 g/t, US$43.82/oz Ag and 15 g/t, US$1,500/oz
Pt and 0.10 g/t, US$1,400/oz Pd and 0.10 g/t. The reader is cautioned that grab samples are selective by nature, and do not necessarily reflect the overall
grade of underlying mineralization.
About Menarik East
The Menarik East project covers an area of approximately 4,200 hectares and comprised 82 exclusive
exploration rights (EERs). The Project is accessed from the west via the Billy Diamond Highway at kilometer-
marker 553 and from the south via the Trans-Taiga Road approximately 11 km east of the junction.
The geology of the Project is characterized by a large ultramafic system, the MIC, that is known for CSM
mineralization, particularly chromium, nickel, platinum group elements, as well as copper and gold
mineralization in deformation zones. It intrudes a folded volcano-sedimentary sequence and felsic intrusion.
The Project contains a historical resource of 1.0 Mt grading 0.38% Ni and 0.15% Cu, and 6.2 Mt grading 7.69%
Cr2O3 and 398 ppb Pd and 105 ppb Pt (see Historic Resource Disclosure below). On the eastern and western
peripheries of the MIC, gold mineralization is present within cross-cutting mafic dykes.
Sampling Protocols and Quality Control
Each rock sample collected in the field was identified, securely bagged and transported to ActLabs (Val-d’Or,
Québec) 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 ICP-OES finish for gold, palladium and platinum, following a 4-acid (near-total) digestion. A strict
