Company Announcements

TORONTO , Sept. 23, 2025 /CNW/ - 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 CUPANI'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 defined 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 hosted 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 aeromagnetic 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 systems 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.
