The Southern Free State (SOFS) projects include Sibanye’s Wits Gold mining right and prospecting right holdings in the Free State goldfields of the Witwatersrand Basin.

The mining right consolidating the De Bron Merriespruit, Bloemhoek, Hakkies and Robijn projects into one mining right has been approved for a period of 23 years and is in the process of being executed. This mining right is contiguous to the north-east of the Beatrix mining right.

Sibanye acquired the De Bron Merriespruit and Bloemhoek projects in December 2013 upon its acquisition in full of Wits Gold.

The Beisa project at Beatrix West is now included in the Mineral Reserve with gold reserves of 0.7Moz and uranium reserves of 16.1Mlb.

The prefeasibility study for this project was enhanced by implementing cut-off grades and leveraging synergies with the current Beatrix West Operation. The principle driver for the Beisa project remains an increase in the uranium price in future. The environmental permitting process for the project, including updating of the Beatrix environmental management programme, will be progressed through 2017.

Gold Mineral Reserves for the De Bron Merriespruit project were reviewed in December 2015 with the mine design and the schedule was replanned in line with revised geological and estimation models. The revised design and updated costing supports the Mineral Reserve for this project, which remains at 2.1Moz.

The Bloemhoek project, which is adjacent to Beatrix North, has a Mineral Resource of 4.3Moz. A prefeasibility study to access the Mineral Resource below infrastructure at Beatrix North, and potentially a portion of this southerly Bloemhoek area with a decline system from Beatrix North, is due for completion mid-2017. Concurrently, an exploration-drilling programme designed to improve geological confidence in the immediate vicinity of the planned decline system will also be completed.
