Golden Star Provides Updates on Wassa Mine

DENVER--(Business Wire)--
Golden Star Resources Ltd. (AMEX: GSS)(TSX: GSC)(GSE: GSR) is
pleased to announce that delivery of high-grade ore from the Benso
property at HBB to the Wassa processing plant commenced in August,
2008. This delivery of ore was originally anticipated to occur in late
September so we are pleased to have the benefit of high-grade material
three weeks earlier than planned.

We further report that Mill 2 at Wassa, which has two identical
ball mills operating independently in parallel, recently experienced a
mechanical breakdown involving the pinion gear assembly. It is
estimated it will take seven to nine weeks to return the mill to full
operation. In the meantime, Mill 1 at Wassa has not been affected and
continues to process treating the ore supply from the Benso and Wassa
pits.

Tom Mair, President and CEO said: "Milling operations at Wassa are
continuing and we will work expeditiously to put Mill 2 back into
operation. Regardless, we are pleased with the earlier than planned
delivery of high grade Benso ore into our plant which will minimize
the impact of the Mill 2 down time. We expect to produce 135,000
ounces of gold from Wassa in 2008 which is the low end of our
guidance. There will be no impact on 2009 guidance."
