TORONTO, Dec. 5, 2016

TORONTO, Dec. 5, 2016 /PRNewswire/ - Golden Star Resources Ltd. (NYSE MKT: GSS; TSX: GSC; GSE: GSR) ("Golden Star" or the "Company") is pleased to report significant results from the drilling program at its Wassa Underground Gold Mine ("Wassa Underground") in Ghana. 

The in-fill drilling program targeted the high grade B Shoot zone of Wassa Underground, focusing on the areas that are expected to be mined with transverse stoping (the "2016 B Shoot transverse stope drilling program"). 

HIGHLIGHTS:

• First nine diamond drill ("DD") results received from the 2016 B Shoot transverse stope drilling program. Significant intercepts included:
  • 31.7 metres ("m") grading 23.8 grams per tonne ("g/t") of gold from 296.8m in hole BS16DD009, including:
    • 6.0m grading 6.7g/t from 296.8m
    • 11.8m grading 40.1g/t from 306.1m
    • 6.0m grading 39.5g/t from 322.5m
  • 8.0m grading 13.9g/t from 57.0m in hole BS16DDD002
  • 18.7m grading 4.25g/t from 322.6m in hole BS16DD004, including:
    • 8.3m grading 8.3g/t from 333.0m
• These results confirm the high grade, wide zones of gold mineralization within the B Shoot transverse stoping areas
• Mineral Reserve and Mineral Resource update expected to be announced in the first quarter of 2017

Sam Coetzer, President and Chief Executive Officer of Golden Star, commented:

"These drilling results continue to confirm the wide zones of high grade gold mineralization in the B Shoot zone.  89% of Wassa Underground's Mineral Reserves are planned to be mined via transverse stoping and we expect to access the first transverse stope in the third quarter of 2017.  Importantly, the deposit remains open down plunge so we believe there is also significant exploration upside potential.  I look forward to announcing further drilling results during the remainder of 2016 and providing an update on our exploration strategy during the first quarter of 2017."
