Mine Life23 years (as of Jan 1, 2020)
In 2014, Sibanye-Stillwater acquired 100% of Wits Gold, the previous owners of the SOFS project areas. The SOFS De Bron Merriespruit (DBM) project was at FS level at the time, and an application for the SOFS mining right was already submitted to the DMRE when Sibanye-Stillwater integrated Wits Gold into the Group. In 2017, the application for the SOFS mining right was executed. While the DBM project is included in the Mineral Reserve, the project has not been approved for execution yet by the Sibanye-Stillwater Board but remains a strategic development option for the Group.

Summary:

Clear patterns of mineralisation, characterised by a highly channelised fluvial depositional environment, can be distinguished.

Expected mineral extraction is estimated to be at depths varying between 450m and 2,500m below surface and will focus on shallow gold/uranium deposits comprising the BXR/VS5, AAR, B and Leader Reefs.
