Second Quarter Financial Results News Release Scheduled for After Market Close on August 8, 2012; Conference Call and Webcast on August 9, 2012, at 11:00 a.m. Eastern Time

DENVER, CO, Jul 17, 2012 (MARKETWIRE via COMTEX) --Golden Star Resources Ltd. (NYSE Amex: GSS) (NYSE MKT: GSS) (TSX: GSC) (GHANA: GSR) ("Golden Star" or the "Company") today announced preliminary second quarter 2012 production results for its Bogoso/Prestea and Wassa/HBB operations.

The Company produced a total of 85,183 ounces of gold in the second quarter ended June 30, 2012, well within its guidance range and nearly 10% higher than first quarter 2012 gold production of 77,725 ounces. During the first half of 2012, the Company produced 162,908 ounces of gold.

The Bogoso/Prestea mine produced 44,115 ounces of gold in the second quarter, up approximately 7% from 41,242 ounces in the first quarter. Wassa/HBB operations produced 41,068 ounces of gold in the second quarter, up approximately 13% from 36,483 ounces in the first quarter.

The Company has not finalized operating cost results but said it expects mining operating costs on a unit basis for the second quarter to be lower than those for the first quarter.

Golden Star's cash balance as of June 30, 2012, totaled approximately $106 million.

During the remainder of 2012 the Company expects to produce approximately 85,000 ounces of gold in the third quarter and approximately 90,000 ounces in the fourth quarter for a total of approximately 338,000 ounces for the full year. This is slightly lower guidance (-3.4%) than previously provided due to lower than expected mined grade from the Pampe pit and lower throughput at the non-refractory plant at Bogoso.
