Production from the Chipmo mine in 3Q12 was 65,362 ounces, 25% higher compared to the 52,265 ounces reported in 3Q11 due to a 16% increase in tonnage treated and 6% higher ore grade (See Appendix 2). The old tailings treatment produced 5,226 gold ounces (compared to 7,906 ounces in 3Q11). Accumulated total gold production in the first nine-month period 2012 was 200,599 ounces, a 6% decrease when compared to 2011 (213,906 ounces). Cash operating cost in 3Q12 was US$537/oz, 3% lower when compared to 3Q11 (US$554/oz). This was mainly explained by the 16% increase in gold ounces recovered due to higher tonnage treated and better ore grades.
