Coloso mine ramp-up contributed to Q2 2025 production, with expectations for increased grades and output in H2 2025 as development continues at both Guitarra and Coloso.
Workforce has grown to about 300, supporting local economic development and benefiting from strong government relations.
Transitioning from rental to owned mining equipment to reduce all-in sustaining costs by $4 per ounce, with plant expansion and process improvements planned.
Technical and resource development
Technical team with deep operational experience, including prior management of the Lagotaro/La Guitarra mine and significant M&A successes.
The 2023 resource update for La Guitarra reported 27.2M silver-equivalent indicated ounces (up 373%) and 20.2M inferred ounces (up 204%), supporting over 40 years of mine life at current rates.
Land package covers 25,000 hectares, including eight or nine former major mines and significant historic production.
Expansion involves adding new cone crushers, ball mills, and a new tailings impoundment to support higher throughput, with sufficient tailings capacity secured for over ten years.
Ongoing resource calculation and metallurgical work are planned for the Tepic project.
Exploration and growth potential
District-wide exploration focuses on the underexplored East District, with a 25,000-meter drill program planned for Q2 next year and over 1,400 drill holes completed.
Historic mines in the district produced exceptionally high grades, with some areas fully permitted for immediate development.
Exploration base established on an 80-hectare site, with potential for a much larger mill in the future.
Historic resource estimates in the district range from 50 to over 200 million ounces of silver (non-compliant).
Expansion ore sources include Lagotara, Colosso, Nazareno, and a high-grade, non-compliant resource at Los Angeles.
