Golden Star Reports Preliminary Fourth Quarter Operational Results

DENVER, CO -- (Marketwire) -- 01/05/12 -- Golden Star Resources Ltd. (NYSE Amex: GSS) (TSX: GSC) (GHANA: GSR) ('Golden Star' or the 'Company') today announced preliminary fourth quarter production results for its Bogoso/Prestea and Wassa/HBB operations.

Production for the fourth quarter of 2011 was 70,738 ounces of gold compared with the guidance of 80,000 ounces. As mentioned in the November conference call, Bogoso/Prestea operations were impacted by the necessity of having to temporarily shut down the sulfide plant and clean out the BIOX® section's blower manifolds in October. Our efforts to catch up to guidance later in the quarter were affected at both mines by intermittent grid power outages and at Bogoso/Prestea by the low mechanical availability of the BIOX® section due to failures of agitators and gearboxes. Wassa was impacted throughout the fourth quarter by wet oxide ores from the high grade Hwini-Butre pits, which caused continuous blockages in the crusher section of the processing plant.

Tom Mair, President and CEO, commented, 'Despite the disappointing shortfall as compared with guidance, we are encouraged by the progress being made at Bogoso/Prestea and Wassa/HBB. Ore stockpiles at both operations are at healthy levels, thereby enabling optimal blending of ores. At Bogoso/Prestea, we now have 12 of 14 BIOX® tanks operational and expect to bring the oxide plant on line in January. At Wassa/HBB we have improved plant throughput, and in 2012 we expect to modify the Wassa plant to accommodate the harder, more siliceous ores being encountered at depth.'

                                Bogoso/Prestea      Wassa/HBB       Combined
