SPC Nickel Identifies Large-Scale Geophysical Targets at the Muskox Copper-Nickel-PGM Project, Nunavut
The MobileMT survey, the first of its kind at Muskox, has successfully outlined multiple large-scale, high-priority conductive target areas across the
Survey Highlights
- Identification of a large, shallow, north-plunging stratiform conductive horizon with a strike length exceeding 27 kilometres, interpreted to represent serpentinized ultramafic rocks occupying the central core of the Muskox Intrusion (Figure 1).
- Delineation of several discrete high-conductivity (low-resistivity) anomalies, ranging from approximately 1 km² to 5 km² in surface area, that extend to depths beneath the interpreted limits of the serpentinized ultramafics. These anomalies are considered prospective for sulphide mineralization and remain open at depth and untested by drilling (Figure 2).
- Many of the high-conductivity anomalies are spatially associated with the basal contact of the Muskox Intrusion and the underlying Feeder Dyke, geological environments known to host high-grade Cu-Ni-PGM mineralization elsewhere within the system.
- A number of priority conductive anomalies are coincident with major regional structures, including the
Canoe Lake , Sinister, and Valley Faults, which may have acted as structural conduits and traps for sulphide mineralization.
Survey Results
Analysis of the MobileMT data has outlined multiple exploration targets, characterized by strong, deep conductive anomalies coincident with interpreted structural features, suggesting a potential for sulphide mineralization associated with basal contact of the Muskox Intrusion and the underlying Feeder Dyke. The Company now has a robust dataset of new airborne surveys, including MobileMT, HELITEM, VLF as well as magnetic datasets, providing a comprehensive understanding of both shallow and deep portions of the Muskox Intrusion and related Feeder Dyke. This multi-layered geophysical framework enhances the ability to vector toward high-priority Cu-Ni-PGM targets with increased confidence. The Company is actively integrating these results with historical data to refine and prioritize future exploration and potential drill targets.

MobileMT uses naturally occurring electromagnetic fields in the frequency range of 25 Hz – 20,000 Hz to map the variations in the electrical conductivity of the subsurface. MobileMT is the most advanced generation of airborne audio-magnetotelluric survey that combines the latest achievements in electronics, advances of modern airborne system design, and sophisticated signal processing techniques. MobileMT is capable of delivering geoelectrical information from shallow to >1 km depth range with high spatial and resistivity resolution. The MobileMT system detects resistivity contrasts of geology structures and boundaries of any shape and in any direction due to total field (three-component) measurements.
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

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.
Length refers to downhole length. Insufficient work has been completed to assess true thickness.
