Our Projects

Two high-grade, development-ready silver assets in Argentina’s premier district.

Strategic Location

Situated within Argentina’s renowned Deseado Massif, Cerro Leon lies along the same structural corridor as AngloGold Ashanti’s world-class Cerro Vanguardia mine, offering significant geological advantages.

Favourable Mining Jurisdiction

Located in Santa Cruz province, a mining-friendly region hosting major operations by Newmont, AngloGold Ashanti, and Pan American Silver, providing a supportive environment for development.​

Corporate Strategy

Unico Silver is executing a two-phased strategy, ‘PLUS 150’ and ‘BEYOND 300’, to transition from an explorer to a developer focused on high-value, free-milling silver resources.

Infrastructure and District Consolidation

Unico Silver has rapidly established a commanding position within a historically underexplored and undercapitalised silver district, completing five acquisitions since late 2022—consolidating two adjacent silver districts for the first time under a single junior.

Joaquin
Joaquin & Cerro Puntudo is a 100% Acquistion of Joaquin Project from Global Major Pan American Silver.
Proven Resource Potential

Joaquin is Unico Silver’s second flagship asset in Argentina’s prolific Santa Cruz province, complementing its Cerro Leon project and enabling potential shared processing opportunities and broader regional development. Acquired from Coeur Mining in 2020, the project brings a robust silver resource and significant brownfields exploration potential. Previously advanced by Coeur, Joaquin benefits from legacy infrastructure, including roads and access routes, which support streamlined reactivation.

Hosts an established JORC-compliant Mineral Resource Estimate of 68.1 million ounces of silver equivalent (AgEq), providing a solid foundation for future development.

Exploration & Development Outlook

With most of the previous drilling concentrated in shallow oxide zones, the Joaquin deposit remains underexplored at depth. Unico sees strong potential to extend known mineralisation and discover additional resources, positioning Joaquin as a critical component of its future production pipeline.

Cerro Leon
Unico Silver holds a 100% interest in the Cerro Leon silver gold districts located in the central Deseado Massif geological province, Santa Cruz Argentina.
Robust Resource Base

Boasting a JORC-compliant Mineral Resource Estimate of 16.47 million tonnes at 172 g/t AgEq, Cerro Leon contains 91.3 million ounces AgEq, including 40.9 Moz silver and 344 koz gold.​

Exploration & Development Outlook

Near-term efforts focus on expanding the robust oxide resource as part of the Plus 150 initiative, targeting 150Moz AgEq of shallow, free-milling silver with strong development potential. In parallel, the Beyond 300 program is underway, with early-stage sulphide discoveries providing a foundation for long-term resource growth and scale. Regional exploration across the broader Sierra Blanca area continues to deliver encouraging results, and a revised Mineral Resource Estimate is scheduled for release in August 2025.
