The decision follows a competitive evaluation process to identify a top-tier engineering partner to advance Diablillos toward a construction decision in the second half of 2026. Worley brings deep expertise in advancing precious metals projects and has recent project delivery experience in Argentina’s lithium sector in the Puna region, near Diablillos. Engineering work will be conducted through Worley’s offices in both Canada and Argentina.

“We are very excited to partner with Worley to unlock the potential of the Diablillos project and advance towards an investment decision”, said Jeremy Weyland, Senior Vice President, Projects and Development. “Their bench strength in mining and mineral processing, and ongoing EPCM work with our neighbours in the lithium sector, provide a unique combination of global expertise and local project execution in Argentina.”

The DFS will incorporate updated Mineral Reserve Estimates following the Company’s recent successful completion of the Phase IV drill program. The study will also focus on advancing several value optimization opportunities in mine planning, power supply, infrastructure layout and a fit-for-purpose review of key capital components. The results from the DFS are expected in Q1/2026, alongside other key milestones including EIA approval by Q4/2025 and qualification under RIGI (Argentina’s investment incentive regime), expected in Q1/2026.

Diablillos is a silver-gold project located in the mining-friendly Salta and Catamarca provinces. The current Proven and Probable Mineral Reserve estimate for Diablillos, from a recently completed Pre-Feasibility Study, consists of 42.3 Mt grading 91 g/t Silver and 0.81 g/t Gold, containing approximately 124 Moz silver and 1.1 Moz gold, with significant further exploration upside potential.
