Argentina - Gualcamayo | Argentina (100% Yamana-owned)
The Gualcamayo mine, located in San Juan province, is an open pit, heap leach operation encompassing three substantial zones of gold mineralization (QDD, AIM and QDD Lower West). An expansion of the operation, completed in 2013, is expected to increase sustainable production.
The increase in production will result from the recently completed transition of mining to the Phase III section of the QDD Main pit, as well as from the start-up of the AIM open pit and the recently completed development of the QDD Lower West underground operation. The underground began contributing to production late in 2013. Recent exploration indicating increasing amounts of sulphide ore in mineral resources prompted a scoping study that is evaluating milling this higher grade material rather than treating it by heap leaching.
