 High-grade assays show Cerro Bayo poised for further growth
Key Points
  • Extremely high-grade assays over extensive areas show potential for continued resource growth at Cerro Bayo
  • Sampling has revealed outcropping veins with grades of more than 10,000g/t silver and 125g/t gold
  • Newly recognised vein structures extend the northern limit of the system by an additional ~1 km, materially expanding the known footprint
Full Summary

Andean Silver Limited has announced the discovery of more extensive vein systems with high-grade silver and gold mineralization at its Cerro Bayo epithermal silver-gold project in Chile. The results demonstrate the significant potential for continued resource growth at the project. Sampling in several areas has returned exceptionally high-grade assays, including 21,282g/t silver equivalent, 10,460g/t silver equivalent, and 13,707g/t silver equivalent. In the Cerro Bayo district, recent mapping, sampling, and geological interpretation have delineated significant strike extensions to multiple sub-parallel vein corridors within the Guanaco Vein Field system, extending the northern limit of the system by an additional ~1 km and materially expanding the known footprint of the epithermal vein field. High-grade saw channel results include 1.7m @ 1,031g/t silver equivalent and 0.5m @ 6,050g/t silver equivalent. Andean is focused on continuing to grow the resource at Cerro Bayo, with a fleet of drill rigs on site and plans to ramp up drilling while advancing the mine study phase in the new year.

Outlook

Andean is focused on continuing to grow the resource at Cerro Bayo, with a fleet of drill rigs on site and plans to ramp up drilling while advancing the mine study phase in the new year. The company's exploration strategy for the coming 12-month period will comprise a combination of drilling brownfields targets, underpinning long-term growth through project generation from regional mapping and discovery, reviewing results and building a comprehensive drill campaign over the greenfield projects, commencing broader regional exploration campaigns, and commencing internal studies to guide the future restart planning phases.
