Burnstone project was previously operated by Great Basin Gold up to 2012 when the mine was placed on care and maintenance and GBG went into liquidation. An option on the mine was acquired by Wits Gold which in turn was acquired by Sibanye-Stillwater. A feasibility study on the gold project was completed in 2015, and project development started in 2016. Total capital expenditure was estimated at R1.852 billion. The Sibanye-Stillwater Board gave approval for the project in Q1 2021 after development paused in 2018 and a revised mining study was conducted. The revised mine plan is expecting production until 2044 while producing at a steady-state production rate of 90ktpm within eight years.
