Strategic focus and asset portfolio

• Metates is among the world's largest undeveloped gold-silver deposits, with a measured and indicated resource of 16.8Moz gold and 423Moz silver, plus 2.1Moz gold and 59Moz silver inferred.

• The company is prioritizing Metates development, proprietary oxidative leach technology, and the Lucy gold project, while divesting non-core assets like Tatatila for equity and royalty upside.

• Well-funded with approximately C$10 million in treasury and strong shareholder support, including over 35% insider ownership.

Metates project highlights

• The 2021 PEA outlines a 15ktpd sulphide heap leach starter project with a 31-year mine life, initial capex of US$359M, and average annual production of 147Koz AuEq (years 1-15).

• Operating cash costs are US$686/oz Au, AISC is US$749/oz Au, and pre-tax NPV (5%) is US$1.14B at $1,600/oz gold and $22/oz silver, with a 35% IRR and 2.5-year payback.

• The project benefits from a 90% reduction in capex versus the 2016 PFS, a compact site layout, and lower environmental footprint.

• Updated drilling in 2021/22 confirmed a higher-grade core, improving gold grades by over 15% in key zones.

Proprietary oxidative leach technology

• The technology enables gold recoveries exceeding 70% from refractory sulphide ores, with successful testwork at Metates and third-party sites.

• It reduces water, energy, and GHG emissions compared to conventional autoclave processes, supporting a "Green Gold" approach.

• The technology is protected by patents and is being commercialized for broader industry application.
