The Amancaya mine is located in northern Chile approximately 200km south east of Antofagasta. The mine was acquired by Austral Gold in 2014 from Yamana Gold, after which open pit operations began in March 2017.

Ore from Amancaya is trucked about 70km to Austral’s plant at the Guanaco mine where material is batch processed due to its different metallurgical characteristics. Ore is crushed and processed by a 1,500tpd agitation leach plant before a pregnant solution is passed into a Merrill-Crowe circuit where gold and silver doré is produced.

Exploration to date at Amancaya represents the early development of a small part of an extensive vein swarm where the extent and pattern of low sulphidation epithermal veining shows some similarities to that at the El Penon mine in same region, which is set to produce 10Moz of gold at an average grade of 7.5g/t AuEq over a possible final 20 year life of mine. Numerous epithermal veins have been mapped at Amancaya since 2016 and significant areas of the licence remain covered by later volcanics and thin sediment cover.

Most current exploration is near the active underground mine, concentrated on understanding and extending the Central Vein and adjacent Oeste Vein, with preliminary work elsewhere in the tenement encouraging with widespread strong rock chips, trenching and reconnaissance drilling.
