Golden Star Announces Signing of the Negotiated Resettlement Agreement for the Community of Dumasi

TORONTO -- (MARKETWIRE) -- 03/05/13 -- Golden Star Resources Ltd. (NYSE MKT: GSS) (TSX: GSC) (GHANA: GSR) ("Golden Star" or the "Company") is pleased to announce the signing of the negotiated resettlement agreement (the "Agreement") which will enable the relocation of the community of Dumasi to a new site.

The community of Dumasi is located upon the Dumasi deposit, which is a key orebody for the Company's Bogoso Mine. The orebody is Bogoso's largest undeveloped open pit mine on the concession and, as at December 31, 2012, contained National Instrument 43-101 compliant Proven and Probable Mineral Reserves of 15.3 million tonnes grading 2.19 g/t for 1.08 million ounces of gold (refer to Golden Star's press release from February 5, 2013 titled "Golden Star Announces Mineral Reserves and Resources Estimates as at December 31, 2012"). Dumasi is located approximately 4 kilometres north of the Bogoso processing plant complex. Production from the Dumasi deposit is expected to begin in early 2015 and will feed both the non-refractory and the refractory plants at Bogoso for several years to come.

Sam Coetzer , President and CEO of Golden Star, commented: "The signing of this Agreement is the next step in our strategy of unlocking value for shareholders from the Bogoso concession. We have worked diligently with the community and the government to arrive at this Agreement that satisfies the needs of the community, the Ghanaian regulators, and the Company. The Dumasi Pit is an important element of the Company's future and will provide both refractory and non-refractory ore sources for at least 6 years from 2015. We are also pleased to announce that ground is already being cleared at the new Dumasi community site in anticipation of construction beginning in the next quarter. The signing of this Agreement is a testament to the dedication and hard work on the part of our employees and the community, combined with the people of Dumasi's goodwill and belief in development for the benefit of the community at large and the cooperation and assistance of the Environmental Protection Agency of the Government of Ghana."
