Golden Star Resources Ltd was a Canadian company that owned and operated the Wassa gold mine in Ghana.

Golden Star Resources was founded in 1984 by geologist Roger Morton and former football player Dave Fennell to pursue mineral interest in Guyana and formed a joint venture with Cambior to develop the Omai Mine.

[5][6] In 1993, the company moved its headquarters from Edmonton to Littleton, Colorado, and based on its 35% stake in the Cambior-operated Omai mine and exploration efforts elsewhere it was listed on the TSE 300 index.

[8] In 1999, as the company was removed from the TSE 300 index, it sought to change its business strategy from exploration to production by replacing Fennell as CEO with Peter Bradford,[9] acquiring an older producing mine in Ghana, and selling its remaining stakes in Omai and Rosebel to Cambior.

[20] Golden Star Resources formerly operated the Bogoso-Prestea gold mine which is located in between the towns of Bogoso and Prestea in the Western Region of Ghana.

Golden Star Resources was also formerly involved in the Omai gold mine in Cuyuni-Mazaruni, Guyana, which was operated by Cambior, but sold its stake in 2001.
