The Escobal project consists of three exploration concessions, Oasis, Lucero and Andres covering 129km2. Exploration work following the completion of a Preliminary Economic Assessment (PEA) completed in November 2010 added a significant tonnage of high grade resources to the Escobal mineral inventory. This prompted an update to the PEA in May 2012 which outlined the cases for an increase in mine production to 4,500t/d and 5,500t/d compared with the first report. The mine licence has been currently suspended whilst a review of an action brought by the anti-mining organisation, CALAS, is carried out. The mine has been placed in stand-by.
