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.
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

CuEq represents CuEq calculated based on the following metal prices (USD) : 4,000 $/oz Au, 52.00 $/oz Ag, 1,400 $/oz Pd, 1,600 $/oz Pt, 4.90 $/lb Cu and 6.80 $/lb Ni, and a recovery grade of 80% for all commodities, consistent with comparable peers. |
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
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.

About the Muskox Intrusion
Originally discovered in the 1950s by Inco,
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

3 by
Silvermet Corporation (2007) and - 13.74 metres @ 5.04% Cu, 2.21% Ni and 5.63 g/t PGM 4 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.
