Unico Silver (ASX:USL) has returned assays from an ongoing 30,000m drilling program that extends the resource estimate at the Joaquin Project in Santa Cruz, Argentina.
Assays have been returned from 75 drill holes, which the company says have delivered ‘strong’ gold-silver intercepts across multiple prospects.
Intercepts include 11.25m @ 1,301 grams per tonne silver equivalent from 127.4m, including 6.8m @ 1,984g/t silver equivalent from 131.2m; 23.5m @ 266g/t silver equivalent from 155m, including 14.2m @ 397g/t silver equivalent from 163m; and 29.4m @ 152g/t silver equivalent from 51m.
Managing Director Todd Williams says drill results from the Joaquin Project have continued to be “strong and consistent”, with mineralisation now extending beyond the resource estimate for multiple prospects.
“At Breccia Puntudo, the latest results represent the highest grades recorded to date and reinforce the potential of this structure as a key source of high-grade feed for the upcoming PFS [Prefeasibility Study],” Williams says.
“Importantly, mineralisation remains open along the 3.5km trend, with clear upside through further definition of high-grade shoots.
“At La Negra SE and La Morocha SE, step-out and extensional drilling continues to deliver wide zones of oxide mineralisation, confirming strong continuity and supporting further resource growth.
“These outcomes strengthen our strategy of building a scalable, high-margin oxide inventory, with a clear focus on converting resources to higher-confidence categories and advancing material into the development pipeline.”
As reported by Mining.com.au, Unico increased the project’s resource by 143% in March 2026 to 45.3 million tonnes @ 115 g/t silver equivalent, yielding 167 million ounces of silver equivalent.
Unico Silver is a mineral explorer focused on discovering silver and gold deposits in Argentina’s Santa Cruz region.
