SPC Nickel Reports Grades up to 18.15% Cu, 97.90 g/t Pd, 11.65 g/t Pt, 4.89 g/t Au from 2025 Surface Sampling at the Muskox Project, Nunavut

High-grade samples highlight scale, continuity, and mineralization of the Muskox magmatic system.

SUDBURY, ON, Nov. 24, 2025 /CNW/ - SPC Nickel Corp. (TSXV: SPC) ("SPC Nickel" or the "Company"), is pleased to announce assay results from the 2025 exploration program at its 100%-owned, 496 km² Muskox Cu-Ni-PGM Project ("Muskox" or the "Project"), located roughly 75 km south of the coastal Hamlet of Kugluktuk in the Kitikmeot Region of Nunavut.

Results from the program confirm widespread high-grade copper, nickel and PGM mineralization occurring across multiple geological environments within the 125 km long Muskox Intrusion - one of the last undeveloped district-scale Cu-Ni-PGM opportunities globally. Mineralization styles and geological characteristics observed are directly comparable to globally significant nickel districts including Norilsk-Talnakh, Voisey's Bay and Sudbury.

Note: Grab samples are selective by nature and values reported may not be representative of mineralized zones. More detailed results are presented in Tables 1, 2, 3, 4 and 5 below while a comprehensive compilation of grab samples may be found on SPC Nickel's web site here.  

Grant Mourre, President and CEO of SPC Nickel commented, "The results from our summer 2025 field program underscore the unique geologic potential of the Muskox Project and position it as a leading exploration opportunity possessing the scale and mineralization typically associated with world-class copper-nickel districts. We are more than encouraged by standout results that include CuEq grades up to 70.62% at Equinox, multiple samples above 30% CuEq at Speers Lake, and consistent high-grade Cu-Ni-PGM mineralization across all target areas.

The combination of consistently high-grade results, multiple mineralization styles, and the broad distribution of numerous mineralized targets reinforces Muskox as a large-scale, metal-bearing district with the potential to host multiple deposits. Many of the 2025 assay results exceed grades from previous campaigns, further emphasizing the untapped exploration potential of the 125-km-long intrusion. These results strengthen our view that Muskox is one of the - if not the - most compelling undeveloped district-scale polymetallic opportunities anywhere."

2025 Program Summary

SPC Nickel completed a seven-day prospecting program in August, supported by daily helicopter access from Kugluktuk. A total of 77 samples were collected across the Equinox, Pyrrhotite Lake, Speers Lake, and additional target areas within the Main Muskox Intrusion and within the 60 km long Feeder Dyke located south of the main intrusion (Figures 1, 2, 3).

Given the extensive gossan development along the margins of the Muskox Intrusion, a diamond-bladed channel saw was used to obtain fresh, minimally oxidized/weathered material for analysis. At the Equinox Target, several continuous channel samples were also cut across the main surface exposure (see Table 2 and Figure 4).

Highlights: Equinox Target (Table 1 and 2, Figure 4)

• A total of twenty-seven samples were collected from two historical showings (Equinox Target and Equinox North Target) located 1,000m apart.
• The Equinox Target hosts sharp-walled massive Cu-PGM veins dominated by chalcopyrite-cubanite-pyrrhotite-pentlandite up to 20 cm thick, associated in fractures within the strongly metamorphosed footwall. Samples returned values as high as 18.15% Cu, 0.06% Ni and 114.44 g/t PGMs.
• Assay results indicated a highly fractionated sulphide, highly enriched in Pd-Pt-Au and Ag similar to the footwall orebodies of the Sudbury Mining Camp.
• A continuous channel sample across the exposed mineralized zone returned 6.85% Cu, 0.08% Ni and 23.64 g/t PGMs over 3.5 metres (Table 2, Figure 4).
• The Equinox North Target hosts massive to semi-massive Cu-Ni-PGM mineralization dominated by pyrrhotite-pentlandite-chalcopyrite hosted within the hornfels zone along/near the contact of the intrusion.

Highlights: Speers Lake Target (Table 3)

• A total of eight samples were collected from the Speers Lake Target located 15 km north of the Equinox Target.
• The Speers Lake Target hosts sharp-walled massive Cu-Ni-PGM veins dominated by chalcopyrite-cubanite-pyrrhotite-pentlandite up to 20 cm thick, associated in fractures within the strongly metamorphosed footwall.
• The Speers Lake mineralized showing significant Ni-enrichment, with lower PGM values compared to the Equinox Target with assays as high as 17.70% Cu, 6.24% Ni and 9.85 g/t PGMs.

Highlights: Pyrrhotite Lake Target (Table 4)

• A total of ten samples were collected from the Pyrrhotite Lake Target located 5 km south of the Equinox Target.
• The Pyrrhotite Lake Target hosts massive to semi-massive Cu-Ni-PGM mineralization dominated by pyrrhotite-pentlandite-chalcopyrite hosted within the hornfels zone along/near the contact of the intrusion. Samples returned values as high as 3.57% Cu, 2.50% Ni and 0.58 g/t PGMs.
• Narrow, fracture controlled sharp-walled massive Cu-PGM veins and blebby chalcopyrite are present associated with fractures within the strongly metamorphosed footwall. Samples returned values as high as 1.46% Cu, 0.04% Ni and 4.71 g/t PGMs.
• A new style of mineralization was encountered in the adjacent footwall metasediments that consisted of a well-developed breccia hosting anastomosing veins of massive sphalerite and native silver. Sample returned value of 23.7% Zn and 7,500 g/t Ag.

Highlights: Feeder Dyke (Table 5)

• A total of eighteen samples were collected from four locations along the 60 km long Muskox Feeder Dyke including the SKOX, SKOX South and Spider Lake Targets.
• Net-textured, coarse-grained blebby to disseminated sulphides were observed at all four sample locations.
• Sulphides were dominated by chalcopyrite-pyrrhotite +/- pentlandite.
• Sample values as high as 6.01% Cu, 0.14% Ni and 28.45 g/t PGMs were reported.

About the Muskox Intrusion

Originally discovered in the 1950s by Inco, SPC Nickel's Muskox Project, located in Nunavut, Canada, represents one of the most prospective greenfield polymetallic copper, nickel, and PGM projects globally. The district-scale land package (496 km²) covers the majority of the Muskox Intrusion, a large, layered mafic-ultramafic body with striking geological similarities to some of the world's most significant copper-nickel-PGM deposits, such as the massive Norilsk-Talnakh deposit.  

The Muskox Intrusion is one of the largest and least deformed layered mafic to ultramafic bodies in the world. It was emplaced during a large magmatic event (Mackenzie Magmatic Event) in the Proterozoic by mantle plume volcanism related to the widespread Coppermine River Group flood basalts. The intrusion is broadly composed of two distinct, but related, components called the Main Muskox Intrusion and the Feeder Dyke, which combined are exposed over a length of 125 km, and range in width from 200-600 metres in the Feeder Dyke to 11 km in the Main Body of the intrusion.

Previous exploration programs completed on SPC Nickel property over a roughly 60-year period identified widespread high-grade polymetallic sulphide mineralization along the basal contact of the intrusion or in the adjacent footwall, similar to the Sudbury and Norilsk-Talnakh camps. Historical drill highlights from the Muskox Project include:

• 7.50 metres @ 6.14% Cu, 2.76% Ni and 9.06 g/t PGM (Pt+Pd+Au)³ by Silvermet Corporation (2007) and
• 13.74 metres @ 5.04% Cu, 2.21% Ni and 5.63 g/t PGM⁴ by Equinox Resources Ltd. (1987).

These results, combined with an extensive footprint of magmatic sulfide mineralization, historical high-grade drill intercepts, untested geophysical targets and limited modern follow-up, underscore the Project's discovery potential.
