Impala Platinum (Implats) plans to start building a new palladium mine that could begin producing as soon as 2024 as the company’s outlook for metals turns bullish. Implats, as the second-biggest platinum miner is known, plans to start work on the Waterberg project in South Africa in 2021, CEO Nico Muller said. The producer is also considering boosting output at its jointly held Mimosa mine in Zimbabwe by 30% as it bets on a long-term shift in platinum-group metals prices, Muller said.
