Northstar Intersects High-Grade VMS Depth Extension at Cam Copper 3.05% Cu, 5.9 g/t Au, 22.9 g/t Ag, 0.45% Mo over 3.07 Metres; 13.95% Cu Bornite Intercept at Depth

Executive Summary

• Northstar Gold Corp. released assay results from a 7‑hole, 1,204 m Zone 2 definition drill program at its 100% owned Cam Copper Mine.
• Significant high‑grade intercepts were reported, including 3.05 % Cu, 5.9 g/t Au, 22.9 g/t Ag and 0.45 % Mo over 3.07 m (hole CC‑25‑14) and 13.95 % Cu, 0.62 g/t Au, 32 g/t Ag over 0.56 m (hole CC‑25‑16).
• The results confirm a robust Besshi‑type VMS system with down‑plunge continuity, supporting further exploration, a forthcoming NI 43‑101 Technical Report, and the planned Surgical Mining pilot targeting up to ~120 kt of high‑grade copper material.

Key Details

• Drill Program: 7 holes, total depth 1,204 m completed Dec 2025; purpose – definition drilling for NI 43‑101 technical report & mineral resource estimate.
• Key Intercepts:
• Hole CC‑25‑14: 3.05 % Cu, 5.9 g/t Au, 22.9 g/t Ag, 0.45 % Mo over 3.07 m (163.05–166.12 m).
• Hole CC‑25‑16: 13.95 % Cu, 0.62 g/t Au, 32 g/t Ag over 0.56 m (202.72–203.28 m).
• Hole CC‑25‑17A (Zone 1 discovery): 4.38 % Cu over 0.6 m (97.7–98.3 m).
• Geological Interpretation: Steeply plunging VMS feeder system; mineralization associated with gabbro sill horizons acting as thermal/permeability traps.
• Next Steps: Update 3‑D geological model, conduct step‑out drilling along down‑plunge extension of Zone 2, and issue NI 43‑101 Technical Report & Mineral Resource Estimate (via Micon).
• Surgical Mining Pilot: Under definitive Turnkey Surgical Mining Services Agreement with Novamera Inc. (Oct 9 2025) and Master Project Agreement (Nov 24 2025); pilot aims to extract up to 120,000 t of copper‑rich material over ~31 months using precision drilling & immediate backfill.
• Consortium Funding: DIGITAL approved up to $4.0 M co‑investment for the ~$11 M Cam Copper Surgical Mining initiative; initial reimbursement of ≈$300 k expected mid‑April 2026.
• Revenue Share: Novamera will receive a 5 % revenue share from the pilot project.
• Qualified Person: Chris Keech, P.Geo., Principal Geologist, CGK Consulting Services Inc., reviewed and approved all technical data.

Notable Quotes

“Zone 2 drilling continues to deliver exceptional results for Northstar… The discovery of this new Cu‑Au‑Ag‑Mo mineralization enhances our geological model as we continue advancing plans with Novamera to potentially exploit near‑surface high‑grade copper at Cam Copper using Surgical Mining™ technology.” – Brian Fowler, President & CEO
