Further Significant Resource Growth at Wassa Underground
TORONTO, March 27, 2020 /PRNewswire/ - Golden Star Resources Ltd. (NYSE American: GSS; TSX: GSC; GSE: GSR) ("Golden Star" or the "Company") announces its Mineral Reserves and Mineral Resources estimate as of December 31, 2019.
Highlights
Andrew Wray, Chief Executive Officer of Golden Star, commented:
"It is extremely encouraging to see another significant increase in the overall Resource base at Wassa, which continues to gain real scale and production growth. Through 2019 we focused on improving our geological understanding and confidence in the areas to be mined in 2020 and 2021 with increased definition drilling, which has resulted in an 87% increase in the Proven Mineral Reserve.
We remain excited by the longer term potential at Wassa, and we are focussed on continuing to deliver this potential. Our exploration strategy for the mine in 2020 is transitioning away from further growth of the overall Resource to infill drilling to assist us in better understanding the likely mine plans for the southern extension of the underground operation. We understand that developing suitable drilling platforms from underground form a critical path item to realizing this objective.
At Prestea, the focus of our drilling in 2019 and into 2020 has been to better understand the geology of the ore body in order to execute the revised mine plan with a modified Alimak method on 24 level and the introduction of the Long Hole Open Stoping ("LHOS") method on 17 level. As a result, we have seen some depletion of the Reserve and no overall additions to the Resource base, but this remains a high grade asset and our focus is on the disciplined mining of the identified Reserve."

MINERAL RESERVE ESTIMATE: BREAKDOWN BY ASSET
During 2019, Golden Star's Proven and Probable Mineral Reserves decreased by 77koz, primarily as a result of the mining depletion of 221koz exceeding the Reserve additions of 147koz.
At Wassa, mining depletion was 166koz with additions from material mined out of Reserve during 2019 (18koz) and material defined by definition drilling informed stope designs (87koz). The material mined outside of the Reserves consisted of stope extensions defined by drilling completed during 2019 and marginal material taken as ore from development headings totalling 271kt at 2.1g/t.
At Prestea, mining depletion was 55koz with additions from open pit mining out of Reserve during 2019 (28koz) and additional ore now included in the mine plan due to mine design changes with the introduction of the new stoping method.
The following table provides a breakdown of Golden Star's estimated Proven and Probable Mineral Reserves as of the dates set forth therein:
