SPC Nickel identifies targets at Muskox project

Executive Summary

• SPC Nickel Corp. has released results from a 1,109-line-kilometre MobileMT electromagnetic geophysical survey conducted at its 100%-owned Muskox Copper-Nickel-PGM project in Nunavut.
• The survey identified multiple large-scale, high-priority conductive targets, including a major north-plunging stratiform conductive horizon with a strike length exceeding 27 kilometres, interpreted as serpentinized ultramafic rocks.
• Several discrete high-conductivity anomalies (1 to 5 square km) were delineated that extend beneath the interpreted limits of the serpentinized ultramafics, remain open at depth, and are untested by drilling.

Key Details

• Survey Scope: 1,109 line-kilometres of MobileMT electromagnetic survey, the first of its kind at the Muskox project.
• Survey Period: Flown between July 28 and August 3, 2025.
• Survey Coverage: 1,031 km of traverse lines (200-500m spacing) and 78 km of tie lines.
• Primary Target Identified: A large, shallow, north-plunging stratiform conductive horizon with a strike length exceeding 27 km, interpreted to represent serpentinized ultramafic rocks in the central core of the Muskox intrusion.
• Secondary Targets: Delineation of discrete high-conductivity (low-resistivity) anomalies ranging from approximately 1 square km to 5 square km in surface area.
• Target Characteristics:
  • Anomalies extend to depths beneath the interpreted limits of the serpentinized ultramafics.
  • Anomalies are considered prospective for sulphide mineralization.
  • Targets remain open at depth and untested by drilling.
  • Many anomalies are spatially associated with the basal contact of the Muskox intrusion and the underlying Feeder dike.
  • Priority anomalies are coincident with major regional structures (Canoe Lake, Sinister, and Valley faults), which may have acted as conduits for mineralization.
• Geological Context: The Muskox intrusion is a large, layered mafic-ultramafic body with similarities to the Norilsk-Talnakh deposit. It consists of the Main Muskox intrusion and the Feeder dike, exposed over 125 km.
• Historical Drill Highlights (Unverified by current QP):
  • Silvermet Corp. (2007): 7.50 metres at 6.14% Cu, 2.76% Ni, and 9.06 g/t PGM (Pt+Pd+Au).
  • Equinox Resources Ltd. (1987): 13.74 metres at 5.04% Cu, 2.21% Ni, and 5.63 g/t PGM.
• Future Plans: The company intends to use this data to sharpen targeting and advance a focused, data-driven exploration program in 2026 to test the strongest conductors.

Notable Quotes

• "The results from our MobileMT survey represent a significant step-change for Muskox. For the first time in more than two decades, we now have modern, property-wide geophysics that provides a much clearer view of the system at depth and helps us separate broad geology from the discrete conductors that matter most." — Grant Mourre, President and CEO
