St-Georges identifies new target zone at Manicouagan

Executive Summary

• St-Georges Eco-Mining Corp. announced the identification of a new high-grade nickel-copper-PGE target zone ("Southeast Manic") at its Manicouagan project in Quebec, following a fall 2025 surface prospecting campaign.
• The company’s wholly owned subsidiary, St-Georges Metallurgy Corp., generated its first revenue in October 2025, with expectations of further revenue from processing geothermal scaling concentrate from Iceland in 2026.
• The new discovery features grab samples with significant nickel, copper, cobalt, and platinum group element (PGE) values, strengthening the geological model of an impact-modified magmatic system and prompting plans for a 2026 drill program.

Key Details

• New Discovery (Southeast Manic Zone):
  • Located approximately 6.5 km east of the known Bob mineralized corridor.
  • Grab sample results: Up to 2.28% Ni, 0.37% Cu, 0.17% Co, and 0.81 g/t Pd + 0.55 g/t Pt.
  • Samples contain high-iron, magnetite-rich lenses (several >70% Fe3O4) consistent with massive magnetite-sulphide horizons.
  • Strong positive correlation (r = 0.83 to 0.95) between Ni, Co, Fe, and PGEs, suggesting a common magmatic sulphide origin.
• Stream Sediment Anomalies:
  • Samples collected 3.5 km east of the project detected trace platinum values of 0.013 g/t Pt (Pd below detection limits).
  • Results suggest a potential distal PGE dispersion plume, indicating the PGE-bearing system may extend beyond the current surface sampling area.
• Bob Zone Historical Data:
  • Drill intercepts: 2m of 3.2% Ni, 0.4% Cu, 0.2% Co, and 9 g/t PGEs.
  • Continuous low-grade mineralization: 91.3m of 0.24% Ni, 0.25% Cu, 0.01% Co.
  • Bulk sample from surface: Massive pyrrhotite-nickel-copper-cobalt-PGE mineralization averaging 2.6% Ni, 1.7% Cu, 0.10% Co, and 12 g/t PGEs.
• Geological Model:
  • Integration of 2022-2024 drilling and 2025 surface work defines a broad structural corridor (5 km long, 2 km wide) centered on the Bob zone.
  • Model suggests an impact-modified magmatic system where deep feeder intrusions and impact structures localize Ni-Cu-Co-PGE mineralization.
• Subsidiary Revenue:
  • St-Georges Metallurgy Corp. generated first revenue in October 2025.
  • Anticipated bulk of future revenue (2026) from processing the first multiton shipment of geothermal scaling concentrate from Iceland.
• Next Steps:
  • Conduct high-resolution ground magnetic and EM survey.
  • Perform mechanized trenching and channel sampling over the Southeast Manic zone.
  • Update 3-D geological model.
  • Prepare 2026 drill program targeting Bob zone depth extensions and the new Southeast area.
• QA/QC:
  • Samples analyzed by IGS Laboratories (ISO/IEC 17025 accredited).
  • Methods: Four-acid digestion with ICP-OES for base metals; Fire assay ICP-OES for PGEs.

Notable Quotes

• "The surface campaign was designed to examine areas with geophysical context similar to our known areas of mineralization (...) This work confirms similar mineralization to other targets on our project. Because of these results, the company will request authorization to test for mineralization at depth with drilling. We exceeded our goal to document mineralized outcrops and collect the supporting data needed for the next phase of exploration. While these results come primarily from select grab samples and are not necessarily representative of the wider area, they are nonetheless a very encouraging sign. In addition, one of the stream sediment samples, collected on the eastern limits of the project, even contained trace amounts of platinum -- providing further context to the broader mineral potential we are defining," commented Herb Duerr, president and chief executive officer of St-Georges.
