TORONTO -- (Marketwired) -- 04/04/13 -- Golden Star Resources Ltd. (NYSE MKT: GSS) (TSX: GSC) (GHANA: GSR) ("Golden Star" or the "Company") today announced its preliminary production results for its Bogoso/Prestea and Wassa/HBB operations for the three month period ended March 31, 2013.

In the first quarter of 2013 the Company sold a total of 81,358 ounces ("oz") of gold ("Au") at an average realized price of $1,634 per ounce.

• Bogoso/Prestea mine sold 35,492 oz Au for the quarter
• Wassa/HBB operations sold 45,866 oz Au for the quarter

Sam Coetzer , President and CEO, commented, "The first quarter production of 81,358 ounces of gold is a very positive accomplishment despite the extended planned maintenance shutdown of the SAG mill at the Bogoso sulfide plant during the quarter which deferred some of our first quarter production into the second quarter. We are on track to meet our production guidance estimate for the year."
