Identification of High Priority Corridor
IDENTIFICATION OF A NEW HIGH-POTENTIAL CORRIDOR AT BLUE LAKE
Toronto, Ontario – September 23, 2025 – CUPANI Metals Corporation (“CUPANI” or the
“Company”) (CSE: CUPA , OTCQB: CUPIF ) is pleased to announce initial results from its
summer exploration program on its 100%-owned Blue Lake Property (the Property). The program
has led to a significant new geological interpretation and the discovery of two new mineralized
zones. The new interpretation highlights a 1.5 km by 12 km high-potential corridor composed of
a series of interpreted fertile ultramafic sub-volcanic conduits.
The northwestern section of this corridor hosts approximately half a dozen mineralized zones
originally discovered in the 1960s . These zones contain a combined historical resource of 4.37
million tonnes grading 2.28% Cu Eq (not NI 43-101 compliant). Each zone is now interpreted to
lie within magmatic conduits that continues and plunges at a low angle to the southeast.
Following and targeting these fertile conduits is an important exploration strategy in magmatic
Cu-Ni-Co-PGE environments. This newly defined high-potential corridor will now be the primary
focus of C UPANI’s exploration efforts. Upcoming works include an electromagnetic ground
geophysical survey, followed by a drill program planned for Winter 2025.
J. Gauthier, VP Exploration, observed: “The recognition of a series of fertile ultramafic conduits,
potentially extending up to 12 km south-east of the known mineralisation, is a real game changer.
It allows us to concentrate our exploration efforts on a well define d high-priority sector while
continuing to investigate the rest of the ultramafic sequences that are present all over our 682 km2
Property.”
Highlights of the 2025 Fieldwork
1. Discovery of Two New Mineralised Zones: Pogo Northwest and Retty Lake Northwest
2. Approximately 450 samples were collected, primarily from outcrop and Felsenmeer blocks
– angular blocks formed by freeze-thaw cycles, representing the underlying outcrop
3. A heli-borne magnetic-electromagnetic survey of 5,313 line-kilometers was completed.
Brian Bosse, CEO of Cupani, commented: “This is exactly what I hoped for in 2025. The footprint
of Cupani possibilities just keeps expanding. Most importantly a new geological theory has arisen
which explains existing deposits plus points contiguously southeast from the historical tonnage in
search of additional massive sulfides . Meanwhile geophysics found whole new zones to explore
many miles away from, and off trend of the historical deposits. Jacquelin, Danielle and the whole
team have been wonderful.”
Best Results of the Prospecting and Geological Mapping
Pogo Northwest (partial results)
A new zone was explored during the 2025 summer program, where angular felsenmeer blocks of
mineralized ultramafics were identified and sampled (Figure 2). These angular mineralized
blocks are concentrated over a coincident electromagnetic conductor and magnetic anomaly
aligned with the extension of the Pogo deposit. Two large angular ultramafic blocks mineralized
in pyrite and pyrrhotite returned 0.47% and 0.34% Cu Eq. A mineralised peridotite outcrop was
also identified to the northeast.
Blue Lake North (partial results)
This area was previously explored in 2024 and revisited in 2025. Additional anomalous
ultramafic felsenmeer blocks were sampled, returning values from 0.35% to 0.68% Cu Eq
(Figure 2). The zone lies near the gravity anomaly to the north of Blue Lake. New sample
highlights include:
• Anomalous peridotite outcrops returning 0.19% and 0.15% Cu Eq.
• Two sub-angular peridotite blocks at 0.55% and 0.68% Cu Eq.
• Several sub-angular to rounded ultramafic blocks ranging from 0.35 to 0.47% Cu Eq.
Retty Lake Northwest (results pending)
At the northwest end of Retty Lake, new electromagnetic conductors led to the discovery of
angular to sub-rounded ultramafic felsenmeer blocks with visible mineralization (Figure 3).
Multiple ultramafic blocks containing up to 10% sulfides (pyrrhotite and chalcopyrite) were
identified and sampled (results pending).
Retty Lake West (results pending)
Ground follow-up was conducted at Retty Lake West near historical drill hole A-27 (Figure 3).
Metric-scale angular felsenmeer blocks of ultramafics were identified, trending NW-SE and
containing approximately 10% visible sulfides (pyrrhotite and chalcopyrite) with distinct net-
textured mineralization (results pending). Historical drill hole A-27 intersected:
* 0.6% Cu, 0.56% Ni and 0.3% Zn over 0.7 m and 0.25% Cu, 0.24% Ni over 1.04 m.

New Geological Interpretation: High-Potential Corridor
The new geological interpretation at Blue Lake identifies a series of ultramafic subvolcanic
conduits exhibiting columnar jointing and containing net -textured sulphides. These features are
similar to those observed in the Raglan Belt mining region. These conduits host ed Cu-Ni-PGE
massive sulfide zones at their base. Globally, the most effective exploration strategy in such
environments is to follow these fertile conduits. At Blue Lake, the conduits are expressed at surface
by mottled aero magnetic signatures and short electromagnetic (EM) conductors, bounded by
kilometer-scale formational conductors. These features outline a high-potential corridor measuring
approximately 1.5 km wide by 12 km long, extending towards the southeast, which remains
untested by drilling (Figure 4).
Airborne Electromagnetic Survey
At the end of August 2025, CUPANI completed a helicopter-supported magnetic-electromagnetic
survey over a large portion of the Blue Lake property. The survey totaled 5,313 line -kilometers,
flown perpendicular to the orientation of the lithologies. The survey was conducted by Expert
Geophysics of Newmarket, Ontario, with their proprietary TargetEM26 system, a low -noise and
low-frequency apparatus. This is one of the largest loops and most powerful EM system s in
Canada, potentially allowing to detect discrete conductors at great depths.
CUPANI has received preliminary computer-generated results and is currently working with the
contractor and in-house geophysicist to finalize interpretations for ground-based follow-up.
