Golden Star Resources has reported positive results from exploration drilling on its Wassa and Father Brown deposits in Ghana. At the Wassa underground mine, significant gold mineralization has been intersected 200 meters (m) down plunge to the south of the current inferred mineral resource. At the Father Brown deposit 85 kilometers (km) to the south, drilling has shown that the Adoikrom gold-bearing structure extends more than 200 m further down plunge than indicated by previous drilling.

At Wassa, Golden Star continued inferred resource delineation and conversion drilling into the third quarter of 2019 and will incorporate all results into updated mineral resource and reserve estimates for 2020 budgeting.

Drilling at Wassa during 2019 has focused on three goals: inferred resource expansion through 200-m step-out holes; inferred resource definition drilling on 100-m infill fences; and conversion of inferred to indicated resources drilling on approximately 50-m drill spacing.

At Father Brown, Golden Star has paused its drilling to allow updating of the mineral resource models and to enable its engineers to determine whether the deposit represents a viable underground mining project and whether further drilling is warranted. The Father Brown deposit is characterized by at least two mineralized structures, the Father Brown structure, which strikes roughly north-south and dips to the west at approximately 40°, and the Adoikrom structure, which strikes northeast-southwest and dips approximately 65° to the west.

Drilling to date indicates that the Adoikrom zone is likely the primary gold-bearing fluid pathway.
