Agua Rica is a copper gold molybdenum porphyry deposit. The base case scenario calls for an open pit operation with the ore treated in a 110kt/d concentrator. For the first five years the mine will produce a clean concentrate. After five years the plant will be converted to dual lines one line producing a clean concentrate (80% of output). The other 20% will have a high arsenic content and will further treated on site via leaching and pressure oxidation to produce a gold dore. It is assumed that the mine will use the existing facilities at Alumbrera which is due to be depleted by 2017. To help advance the project Yamana signed a streaming deal with Sandstorm Gold.
