The updated Preliminary Economic Assessment (PEA), prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects, replaces the Company's previous 2023 PEA, which reported a base-case after-tax NPV (5%) of C$6.99 million and an IRR of 23.4%, as disclosed in the technical report dated March 1, 2023, available on SEDAR+.

"This PEA is a milestone for ESGold and a validation of our strategy," said Gordon Robb, CEO of ESGold. "A 60% after-tax IRR, sub-two-year payback, and low initial capex are the hallmarks of a project built to generate cash flow quickly while limiting dilution and execution risk. Just as important, our fully permitted status and construction progress reduce the timeline from paper to pour. With commissioning preparations underway and a robust exploration pipeline, anchored by an upcoming 3D model and recent deep imaging to ~1,200 metres, we see a clear runway to first production by year-end and meaningful growth beyond it. We're excited, aligned, and focused on delivering."

ESGold is advancing a district-scale view of Montauban. A consolidated 3D geological model, integrating 2015 VTEM, historical work, and new ANT deep-imaging-is nearing completion. The previously conducted ambient noise tomography (ANT) survey has traced key structures to ~1,200 m depth, materially deeper than earlier scope, indicating potential for mineralized zones below and beyond historically worked areas.

VMS systems commonly occur in clusters, the emerging structural framework supports the potential for additional lenses outside the current footprint. Broken Hill-style characteristics observed at Montauban, including mineralogy and complex structural overprints, reinforce the interpretation of a broader, multi-lens system typical of high-grade VMS districts. This workstream complements ESGold's near-term production plan while opening blue-sky growth across the camp.

The updated PEA delivers an independent validation of Montauban's economics, reducing project risk by quantifying capital needs, margins, and payback while confirming a practical path from construction to operations. Coupled with full permits and late-stage site work, it strengthens ESGold's position to secure funding on more favourable terms.

Amex Exploration Inc. (TSXV: AMX) (FSE: MX0) (OTCQX: AMXEF) recently announced the results of an updated Preliminary Economic Assessment (the "PEA") for its wholly-owned Perron gold project (the "Project"), located near the towns of Normétal and Valcanton in the province of Quebec, Canada.
