Cerro Bayo Silver-Gold Project

A significant ready-to-go underground & open pit silver-gold mine in the Deseado Massif, Chile.

Large Growth potential with JORC resource of 50.2Moz @ 311g/t AgEq.

Overview

The Cerro Bayo mine is 100% owned by Andean Silver. The mine covers 285sq.km and comprises over 70 contiguous exploration concessions as well as surface properties that covers the areas of the Laguna Verde mining district and processing facilities.
The Cerro Bayo Project was in production for over 15 years, producing more than 45Moz Ag and 650koz Au (~99Moz AgEq). The Project has been on care and maintenance since October 2022.

Geology

The mineralization is typical of a low sulphidation type and is interpreted to be of a multi-stage, open space filling epithermal origin resulting in mineralized veins, stockworks and breccias. Two different mineralization events can be recognized at Taitao. A mesothermal early stage Ag-Mo-Zn-Pb with subordinated gold, well exposed in the Taitao and Breccia zones; and, a late stage typical epithermal gold-silver rich system, of the low sulfidation type, representative of the main mineralization stage of the district, represented by the NW trending Condor vein systems.
Two main vein systems are recognized at Laguna Verde. NS to NNE trending brecciated veins and breccias varying in dip from vertical to 45º E, and N15ºW to N35ºW oriented veins varying in dip between vertical and 75º NW and SE. Strike lengths up to 1.5km have been recognized in some of the vein systems evaluated to date. Widths are highly variable between the different vein systems and in individual veins along-strike and down-dip varying from centimetres up to 50 meters in breccias and stockworks (sheeted zones).

Exploration

There is extensive areas within the existing mine area as well as greenfields targets to support future resource growth. Approximately 50% of the tenure remains undrill tested with a further 25% under drilled. Established greenfield targets within the know tenure that have not been drill tested that will be targeted for future drilling includes the Raul West, Claudia Vein and Draught Master vein swarm.
Further greenfields exploration will be conducted East and Southeast of the Cerro Bayo Dome through to Sinter Hill where the topography increases and early stage programs such as IP and Magnetic surveys, Alteration studies and on ground mapping will need to be conducted to establish target zones.
