Golden Star Announces Senior Operational and Technical Management Changes.

DENVER -- Golden Star Resources Ltd. (AMEX: GSS)(TSX: GSC) today announced the appointment of Colin Belshaw as Vice President Operations and Daniel Owiredu as Vice President Ghana.

Colin Belshaw is a British mining engineer with approximately 30 years' experience in the mining sector in Africa, the Americas and Europe and a background in gold and copper mining in both open pit and underground mining situations. Most recently Colin was employed by Kinross Gold Corporation as Director General Far East Operations and then Group Consulting Mining Engineer in Reno, Nevada.

Daniel Owiredu is a Ghanaian engineer with more than 20 years' experience in the mining sector in Ghana and West Africa. Most recently, Daniel was Deputy Chief Operating Officer for AngloGold Ashanti Ltd. following the amalgamation of AngloGold Ltd. and Ashanti Goldfields Co. Ltd. His prior experience includes successfully managing the construction and operation of the Bibiani mine for Ashanti. He also managed the Siguiri mine in Guinea and the Obuasi mine in Ghana for Ashanti.

Initially, both Colin and Daniel will be based in Ghana at the heart of the Company's business activities. In mid-2007, it is expected that Colin Belshaw will relocate to our Denver headquarters to become Chief Operating Officer while Daniel Owiredu will remain in Ghana and become Vice President Operations, Ghana.

Peter Bradford, President & CEO, said, "These two appointments further strengthen and broaden our senior management team. Both Colin and Daniel deliver strong technical and operational qualifications to Golden Star as well as significant underground mining experience, which become more important in the future as we progress the Prestea Underground mine. In addition, Daniel delivers an excellent understanding of doing business in Ghana which we expect will further strengthen our stakeholder relationships in Ghana."

"Golden Star has grown significantly in the last few years and expects to produce 500,000 ounces in 2007,"continued Mr. Bradford. "Therefore, we have proactively strengthened and expanded our management team. Additionally, we have recently appointed Dr. Mark Thorpe as Vice President Sustainability, to direct the Company's health, safety, environmental and community affairs activities, and Peter Bourke as Vice President Technical Services, to oversee the preparation of our reserves and mining and processing plans. In October, David Partridge joins the Company as General Manager of the Bogoso/Prestea mine, a role which Colin Belshaw has filled since his appointment as Vice President Operations earlier this year. Bruce Higson-Smith, who was acting General Manager at Bogoso/Prestea from late 2005 until Colin Belshaw's appointment, has now resumed his normal role of Vice President Corporate Development on a full time basis."
