Since ore was first mined at the La Arena Gold Mine the gold grade has been significantly higher than planned. This is principally due to mining narrow high grade, vertical or near vertical veins within the larger disseminated ore body. These veins were not identified in the drilling undertaken to generate the reserve model and mine plan. Management cannot predict whether high grade veins will be mined in the future. Overall mining fleet productivity has been lower than planned during the first six months of 2012 due, at various times, to either limited leach pad capacity or waste dump capacity. Both leach pad capacity and waste dump capacity are being increased.
With a proven technical team, strong operating and financial performance and high quality development and exploration projects, Rio Alto is positioned to grow into an intermediate gold producer. Based on current plans and assumptions the Company projects gold oxide production of over 200,000 ounces per year by 2014. All planned development, exploration and capital expenditures for 2012 will be completed without external funding. Rio Alto plans to pursue accretive acquisitions and carry out planned exploration programs.
