St-Georges Reports Progress on Lithium Pilot & Metallurgical Initiatives

MONTRÉAL, QC / ACCESS Newswire / October 14, 2025 / St-Georges Eco-Mining Corp. (CSE:SX)(OTCQB:SXOOF)(FSE:85G1) and its wholly owned subsidiary, St-Georges Metallurgy Corp., provides a corporate update on its lithium production pilot plant and other metallurgical initiatives.

Over the past months, the Company and its partners carefully evaluated potential spodumene suppliers from across Canada. Several suitors expressed interest in providing concentrate. The consortium of partners, Coalia, LiOH Corp., and St-Georges Metallurgy Corp. (SXM), has now received a first shipment of approximately five tons of Canadian-sourced spodumene concentrate. Initial work and testing is underway, with the received material already processed through the alpha-to-beta transformation stage. Regular updates on the program's results will be provided as they become available.

"(…) the SX lithium technology will bring significant advancements to lithium metallurgy through several key improvements over traditional processes. It enables high lithium purity and recovery, reduces the quantity of residues generated, minimizes water, acid, and reagent consumption, and produces valuable by-products such as alumina and nitrogen-based fertilizers. Together, these improvements provide strong economic potential, allowing the process to operate at lower costs than Chinese alternatives. The ongoing pilot project will provide data to support a feasibility study to be initiated by March 2027, which will include a detailed CAPEX and OPEX analysis to confirm the technology's position as one of the most sustainable and cost-effective solutions in the industry (…), commented Mathieu Boudreau, Project Manager at Coalia.

Other Metallurgical Initiatives
SXM continues to advance two nickel-focused projects, supported by grant applications submitted in collaboration with several partners, including a leading tier-one metallurgical process provider. Key contributors to these initiatives include Coalia and Montreal-based IGS.

In parallel, preparations are underway for the comprehensive extraction of valuable minerals through metallurgical processing of previously collected bulk samples from the Julie and Manicouagan Critical Minerals Projects. Processing work is expected to begin before the end of the year.

Additionally, through its wholly owned subsidiary Iceland Resources Ehf, the Company is collaborating with a geothermal energy producer in Iceland. Initial testing of supplied material has reported grades from ~67 g/t Au-eq to ~437 g/t Au-eq or >14 gold-equivalent ounces per ton. Over 200 kilograms of this material have been successfully imported into Canada for extraction and separation testing, which will inform ongoing initiatives aimed at setting a regular operation.
