Golden Star Discovers New Gold Mineralization on the Saramacca Project in Suriname

DENVER--(CCNMatthews - Aug 11, 2005) -

Golden Star Resources Ltd. (AMEX: GSS) (TSX: GSC) announced today that it has completed the first phase of exploration diamond drilling on its 100% owned Saramacca property, located in north-central Suriname, on the Guiana Shield of South America. Significant results from this shallow drilling program are detailed below. The more favorable intersections included:



MA-0007 6.71 meters grading 7.15 g/t Au from 44.3 meters below
surface

MA-0017 14.00 meters grading 4.39 g/t Au from surface

MA-0018 19.5 meters grading 2.49 g/t Au from 12 meters below
surface

MA-0019 4.00 meters grading 3.20 g/t Au from 1 meter below surface



Peter Bradford, President and CEO, said: "These early results demonstrate that the Saramacca area is prospective for significant gold mineralization. The first phase of work successfully identified zones of saprolite-hosted gold mineralization underlying a previously identified auger soil anomaly. The next phase will involve mechanized trenching and drilling with a larger diamond core rig capable of testing the mineralized zone at depth." The first phase of the program comprised 24 shallow diamond drill holes for a total of 1,315 meters.

The Saramacca project covers a 23-kilometer-long Lower Proterozoic volcano-sedimentary greenstone belt along the general structural trend of Cambior's three-million-ounce Rosebel Mine. Two phases of district-scale BLEG (bulk leach extractable gold) drainage sampling carried out by Golden Star have indicated an extensive gold anomaly which stretches for 12 to 15 kilometers along the northern flank of the Brokolonko Range, extending to the southwest of the Rosebel property. Follow-up grid auger soil-sampling over the last two years has defined several areas of gold-in-soil anomalies overlying the contact between metabasalts and metasediments. These areas, known as Anomaly M, extend semi-continuously over a 4-kilometer trend at sampling levels exceeding 100 ppb gold.

The recently completed drill program targeted the central 1,600-meter section of Anomaly M. This was undertaken with a lightweight man-portable drill rig due to the rugged terrain, limiting hole depths to less than 100 meters. Mineralization intersected within drill cores consisted of variably sheared silicified pyritic metasediments of tuffaceous origin and volcanic conglomerates, often with little or no quartz veining. Significant gold assays were also intersected within the upper 5 to 10 meters of enriched duricrust and mottled saprolite.

Significant intersections are summarized below, and detailed drill results along with a location map are available on our website at www.gsr.com:
