Andean Silver Limited’s exploration at the Cerro Bayo project in Chile has extended its high-grade silver and gold corridors by 1.2km. Exceptional rock chip assays underline significant growth potential, bolstering the company’s resource base and sparking investor interest.
Andean Silver Limited has revealed noteworthy exploration advancements at its Cerro Bayo Silver-Gold Project in Chile. The company’s recent efforts have identified an extensive 1.2km mineralised vein system that, together with newly mapped targets, significantly expands the known Droughtmaster Corridor to an area of more than 4km by 3km. Detailed mapping and geophysical surveys have pinpointed highly prospective silver and gold corridors outside the existing resource base, including the Monserrat, Tamara, Sofía, and Pasquerito veins. Some rock chip results are exceptionally high, recording up to 30,202 g/t Ag equivalent (incorporating 16,833 g/t Ag and 161.1 g/t Au), underscoring the project’s potential.
Supportive geophysical work using controlled-source and audio-frequency magnetotellurics has outlined zones of enhanced resistivity and deep-rooted anomalies, with structures traced to depths of 400–500 meters. These findings are closely linked to key epithermal alteration features and silver sulfosalts, which reinforce the target areas as prospective for future bulk mining and resource expansion. In combination with historical exploration data, these new discoveries suggest a strong potential for significant additional mineralisation along previously unmapped and understudied extensions.
A robust on-site drilling program is underway with three rigs focused on both brownfield targets within the high-grade Laguna Verde and existing Cerro Bayo areas and greenfield targets derived from regional mapping and geophysics. The company’s 12-month strategy emphasizes completing the extensive geophysical campaigns, advancing permitting processes, and initiating scout drilling on higher priority targets. These on-ground efforts aim to underpin long-term resource growth and pave the way for future restart studies.
Market sentiment from this update has a bullish tone. The company’s aggressive exploration campaign, marked by substantial vein extensions and remarkable rock chip assay grades, enhances the project’s upside potential and drives investor confidence. However, some caution is warranted as the program is still in the exploration phase, and further drilling and assay results are needed to confirm these early indications. Overall, Andean Silver Limited is positioning itself strongly for a significant resource expansion, though the inherent risks of exploration remain a factor for traders to monitor.
