The Company produced a total of 83,340 ounces of gold in the third quarter ended September 30, 2012, approximately 2% below guidance of 85,000 ounces. Gold sold totaled 80,849 ounces. For the first nine months of 2012, the Company produced 246,248 ounces of gold, up 7% from 230,309 ounces in the comparable nine-month period of 2011.

Golden Star's cash balance as of September 30, 2012, totaled approximately $102.5 million excluding approximately $4.4 million in finished gold held and a substantial increase in gold in process inventory.
