Strategic Location
Located in Santa Cruz province Argentina, a mining-friendly region hosting major operations by Newmont, AngloGold Ashanti, and Pan American Silver, providing a supportive environment for development.
Corporate Strategy
Stage 1 “oxide first” development plan focused on pit-constrained free-milling resource
PFS workstreams underway: Baseline environmental studies, geotechnical drilling, and comminution drilling completed Q4 2025.
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.
Financing (AUD$30m raised in two tranches)
Confirmation of historical metallurgical recoveries.
Metallurgy (PLUS 150 optimisation testwork)
Detailed geotechnical and pit optimisation
Update Joaquin and Cerro Leon baseline environmental and hydrology studies.
Scoping study
RIGI corporate restructure

Joaquin MRE increases to 167 Moz AgEq 
Acquired from Coeur Mining in 2020. Previously advanced by Coeur, Joaquin benefits from legacy infrastructure, including roads and access routes, which support streamlined reactivation.
Established JORC-compliant Mineral Resource Estimate of 167 million ounces of silver equivalent (AgEq). Shared processing opportunities at Cerro Leon and broader regional development.

Jaoquin Project – Historical Production 2019 to 2022
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.
JORC-compliant Mineral Resource Estimate of 31 million tonnes at 161 g/t AgEq, Cerro Leon contains 162 million ounces AgEq, including 61.4 Moz silver and 543 koz gold.

Exploration & Development Outlook
Cerro Leon is host to the second largest vein field (behind AngloGold Ashanti’s Cerro Vanguardia mining complex) with over 130 lineal kilometres of mapped epithermal vein. To date, only 20% of all veins have been tested by drilling, highlighting the huge potential for further discoveries within the district. Regional exploration is focused on the Pinguino and Sierra Blanca properties.
