SnapshotJoaquin Mine was a part of Pan American Silver's Manantial Espejo Operation. The previous owner, Pan American Silver, put Joaquin mine in Argentina in the reclamation phase, and mining activity ceased.

On October 11, 2024, Unico Silver Limited completed the acquisition of the Joaquin Project. The Project consists of two contiguous properties (Joaquin and Cerro Puntudo).

The transaction includes camp infrastructure and a mining and access agreement valid until 2034.

Joaquin contains a historical Foreign Estimate1 of 16.7Mt at 136gpt silver equivalent (AgEq2) for 73Moz AgEq (68Moz Ag, 64koz Au) in the La Negra and La Morocha deposits.

Cerro Puntudo is host to numerous vein targets (Brunilda, La Esmeralda, Isabella) with high silver gold values at surface that are untested by drilling.

Summary:

Mineralization at Joaquin is classified as low sulphidation hydrothermal breccia.

Silver and gold mineralization is hosted within a northwest trending structure that dips approximately 45° to the northeast. The majority of the mineralization is hosted within a silicified breccia, with lesser stockworks and veinlets. Silver is present as native silver, bromargyrite, and acanthite/argentite, with lesser stromeyerite, freibergite, and pyrargyrite/stephanite. The sulphide content is low and consists principally of pyrite and galena. Hematite, jarosite, and manganese oxides are commonly noted. The host minerals are dominated by quartz and feldspar. Hydrothermal alteration is weak to moderate and comprises fine grained replacement quartz and widespread illite and kaolinite alteration.

Mineralization within the economic mine plan is located between approximately 110 m and 310 m below surface and trends for 375 m along strike.
