HIGH-GRADE NICKEL AND PLATINUM GROUP METAL DISCOVERY EXPANDS MANICOUAGAN CRITICAL MINERALS POTENTIAL

St-Georges Eco-Mining Corp. has obtained two major milestones: the first recorded revenues from its wholly owned subsidiary, St-Georges Metallurgy Corp., and the identification of a new high-grade nickel-copper-PGE (platinum group element) target zone at its Manicouagan project in Quebec. These achievements underscore the company's dual focus on advancing critical materials exploration and generating early stage metallurgical revenues.

St-Georges Metallurgy reports first revenue

St-Georges' wholly owned subsidiary, St-Georges Metallurgy, generated its first revenue in October, 2025. The subsidiary might record additional revenue before the end of its financial year and is preparing for further revenues in 2026. It is anticipated that the bulk of the amounts will then originate from the processing of its first multiton shipment of geothermal scaling concentrate from Iceland.

Manicouagan fall 2025 surface prospecting campaign results

The 2025 surface exploration campaign at Manicouagan has refined the project's geological model and led to the discovery of the southeast Manic zone located approximately 6.5 kilometres east of the known Bob mineralized corridor. Two grab samples from this new area returned values up to 2.28 per cent Ni (nickel), 0.37 per cent Cu (copper), 0.17 per cent Co (cobalt), and 0.81 gram per tonne Pd (palladium) plus 0.55 g/t Pt (platinum), confirming the presence of high-iron, magnetite-rich lenses (several samples greater than 70 per cent Fe3O4) with elevated PGE (platinum group element) content consistent with massive magnetite-sulphide horizons.

Investors are cautioned that grab samples are selective by nature and may not be representative of the mineralization on the project.

Strong geological correlation: multielement analysis shows a strong positive correlation between nickel, cobalt, iron and platinum group metals (PGEs) (r equals 0.83 to 0.95), suggesting a common magmatic sulphide origin.

The 2025 surface work was conducted outside of the zone covered by the company's geophysics work of 2022. It does test trends and structural corridors that can be derived from the interpretation made by Fritz Geophysics in its 2023 report, which re-examined the 2022 to 2023 heliborne magnetic survey.

Stream-sediment samples collected far to the east of the project returned trace platinum, adding context to the broad geophysical and structural footprint, and suggesting that the PGE-bearing system extends well beyond the current surface sampling area.

The presence of sulphide-rich rocks outside the previous zone of interest prompted the team to extend sampling and collect stream sediment samples approximately 3.5 kilometres farther east to investigate the potential for prospection of that area. One of the stream sediment samples may indicate a potential upstream anomaly as it detected trace platinum values of 0.013 g/t platinum, while palladium was below detection limits. These results could point out to a distal PGE dispersion plume.

"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.

Geophysical and geological interpretation

The 2022 to 2023 heliborne magnetic survey and subsequent March, 2023, interpretation by Fritz Geophysics refined the project's geological model, outlining contrasting magnetic domains, a possible deep intrusive body, and multiple concentric structures interpreted as secondary impact craters.

Integration of this data with 2022 to 2024 drilling and the new 2025 surface program defines a broad structural corridor over five km long and two kilometres wide centered on the historical Bob zone. The model suggests an impact-modified magmatic system where deep feeder intrusions and impact structures combine to localize Ni-Cu-Co-PGE mineralization.

The Bob zone has drill intercepts of two m of 3.2 per cent Ni, 0.4 per cent Cu, 0.2 per cent Co, nine g/t of PGEs (Pt plus Pd plus Rh plus Ru) and continuous low-grade (that is, 91.3 m of 0.24 per cent Ni, 0.25 per cent Cu, 0.01 per cent Co) mineralization proximal to these features. A bulk sample from surface of Bob mineralization consisted of massive pyrrhotite-nickel-copper-cobalt-platinum-palladium-rhodium-ruthenium mineralization averaging 2.6 per cent Ni, 1.7 per cent Cu, 0.10 per cent Co and 12 g/t of PGEs (Pt-Pd-Rh-Ru-Ps-Ir).

Next steps

The company plans to conduct a high-resolution ground magnetic and EM survey, followed by mechanized trenching and channel sampling over the new South-East Manic zone. The 3-D geological model will be updated, and a 2026 drill program will be prepared to target both the Bob zone depth extensions and the newly extended southeast area of interest.

Quality assurance/quality control (QA/QC)

All samples were collected by a team of experienced prospectors and analyzed by IGS Laboratories, an ISO/IEC 17025 accredited facility in Delson, Que. Analytical methods included four-acid digestion with ICP-OES for base metals and fire assay ICP-OES for PGEs.
