The South Africa-listed miner had taken a 30.29% stake in Keliber in February as part of its diversification strategy into battery metals. It had offered in June to buy minority shareholders out to boost its stake to over 80%.

Keliber aims to be the first fully-integrated lithium producer in Europe, targeting first production in 2024 and ramping up to produce around 15,000 tonnes of lithium hydroxide per year.

Sibanye's Chief Executive Officer Neal Froneman said in a statement that the majority takeover of Keliber would enable "delivery of high quality, low-cost lithium hydroxide with a low carbon footprint into the growing European battery industry."
