 High-Grade Assays from Breccia Puntudo
Key Points
  • First drilling by USL at Breccia Puntudo confirms shallow oxide gold-silver mineralisation
  • Infill drilling at La Negra SE extends mineralisation beyond the current resource
  • Drilling at La Morocha SE continues to deliver wide oxide silver-gold intercepts
Full Summary

Unico Silver Limited (USL) is pleased to report assay results from 56 drill holes totalling 7,823 metres completed as part of the Company's ongoing 30,000m drill program at the 100%-owned Joaquin Project in Argentina. The drilling continues to deliver strong gold-silver intercepts across multiple prospects, including the first drilling completed by USL at the Breccia Puntudo prospect, as well as infill and step-out drilling at La Negra SE and La Morocha SE. Results confirm shallow oxide mineralisation at Breccia Puntudo and demonstrate that mineralisation at La Negra SE remains open to the southeast and at depth, supporting the upcoming JORC (2012) Mineral Resource Estimate currently being finalised as part of the Joaquin Pre-Feasibility Study. Highlights include: first drilling at Breccia Puntudo returning significant intercepts such as 28m at 284g/t AgEq, including 13m at 513g/t AgEq; infill drilling at La Negra SE continuing to return strong gold-silver intercepts, including 65m at 165g/t AgEq and 27m at 162g/t AgEq from the deepest hole drilled to date; and drilling at La Morocha SE delivering wide oxide silver-gold intercepts, such as 77.6m at 94g/t AgEq and 83m at 99g/t AgEq. The Company is encouraged by the exploration success and is progressing the Pre-Feasibility Study workstreams, including geotechnical and metallurgical testwork.

Outlook

Regional scout drilling is ongoing and will focus on the emerging Breccia Puntudo trend. Testwork on geotechnical holes to inform input parameters of pit optimisation studies, comminution (ore hardness) testwork, and Phase 2 baseline environmental field work are planned for the next 3 months.
