Salares Norte project - Geology and mineralisation

The Salares Norte Project is located in the northern part of the Maricunga Belt, an area with a predominance of Cenozoic volcanic rocks, comprising eroded strato-volcanos, volcanic domes and pyroclastic rocks. Mineralisation at Salares Norte is contained in a high-sulphidation epithermal system, hosted mainly by a breccia complex along the contact of two volcanic domes of andesitic and dacitic composition. Mineral Resources have been delineated by drilling in two separate deposits, Brecha Principal and Agua Amarga, which are located about 500m apart. Most of the mineralisation known to date is oxidised. The sulphide mineralisation contains mainly pyrite. Preliminary metallurgical test results indicate gold extraction in the order of 92% using a conventional CIL process on samples of oxidised material.
