South32 threatens to shut Mozambique aluminium smelter as power talks drag on
The diversified miner has been in protracted negotiations with Mozambique's government over a power agreement that is set to expire in March. It warned in July that it may face an impairment at the smelter during fiscal 2025 and was reviewing production after failing to secure affordable power.
"You've got to have a business that can make money through the cycle and at least be cash flow positive and give you some return to your shareholders," CEO Graham Kerr told Reuters.
"The current offer on the table would make us cash flow negative every single month, every single day," he said.
Given care and maintenance was the most likely scenario, South32 said in an exchange filing it would curtail activities such as pot relining and would limit further investment in the operations. The company's shares fell more than 5%.

South32's Mozal Aluminium closure by March 2026 a big blow for Mozambique economy
South32 operates Mozal Aluminum in Mozambique. The smelter employed over 2500 staff last year, but is being put on care and maintenance from March next year due to an inability to reach agreement on a new electricity supply agreement. Image: Supplied South32 said its Mozal Aluminium facility, the biggest industrial employer in Mozambique with over 2 500 staff, will be put on care and maintenance when its electricity agreement expires at the end of March 2026. Apart from the employees and contractors that were employed at Mozal in 2024, an estimated additional 21 000 jobs had been created through multiplier impacts on the economy, the mining group said. South32's share price plunged 5.83% to R33.41 on the JSE early Thursday morning. South32 said in a notice on Thursday that it had continued to engage with the Mozambique government, Hidroeléctrica de Cahora Bassa (HCB), and Eskom on securing additional electricity, as it has been trying to secure an agreement for over six years. South32 also operates the Hillside smelter in Richards Bay, with both smelters supplied with alumina that is mostly mined and imported from Australia. The impact stretches beyond the direct workforce at Mozal, as the facility supports not only smelting operations but also downstream industries and infrastructure development. Anchor Capital analyst Robbie Proctor said the smelter is very important to the Mozambique economy, as it contributed 4% of Mozambique's GDP, and the aluminium exports made up 15% of that country's total goods exports. 'These engagements do not provide confidence that Mozal will secure sufficient and affordable electricity beyond March 2026. As a result, we will limit investment in Mozal, stopping pot relining and standing down associated contractors starting this month,' the global mining group said. South32 would incur an estimated R6.53 billion impairment as a result of the closure. Historically, most of the electricity for Mozal has been generated in Mozambique by a hydroelectric power generator, Hidroeléctrica de Cahora Bassa (HCB). HCB is owned by the Mozambique government. Under the agreement, electricity from Eskom is supplied to Mozal when HCB is unable to meet all of Mozal's electricity requirements. HCB recently indicated that drought conditions might impact its capacity to deliver sufficient hydroelectric power to Mozal, which had increased the uncertainty regarding future electricity supply to Mozal.

Next Stay Close ✕ 'Without access to sufficient and affordable electricity, we expect that Mozal will be placed on care and maintenance at the end of the current agreement,' it said. Proctor said the primary stumbling block has been the electricity tariff. He said another complicating factor behind the talks between the parties was likely to the current agreements also in place between Eskom and Mozambique's energy company, as around two-thirds of the electricity from Cahora Bassa is exported to South Africa. He said the Mozambique government wants Mozal to be supplied directly by the Mozambican energy company, rather than power being sold to Eskom and then being bought back by Mozambique's transmission company. 'So it's more complicated than just renewing the existing agreement with Eskom, as was the case with the Hillside smelter,' said Proctor. Mozal's 2026 financial year production was expected to be about 240kt (South32 share), reflecting fewer pots in operation as pot relining stops and operations continue only to March 2026. Mozal produced 318 000 tons of aluminium in 2024. Hillside, which is Eskom's biggest industrial customer, produced 718 000 tons of aluminium last year. A carrying value assessment of Mozal had been completed, and as a result, South32 would recognise an impairment of $372m for Mozal with its financial results for the 2025 financial year.

South32 threatens to shut Mozambique aluminium smelter as power talks drag on
Australia's South32 on Thursday flagged a $372m (R6.53bn) impairment on its Mozambique aluminium smelter which the miner said it was preparing to mothball as it may not be able to secure affordable power when its supply agreement ends in 2026. The diversified miner has been in protracted negotiations with Mozambique's government over a power agreement that is set to expire in March. It warned in July that it may face an impairment at the smelter during fiscal 2025 and was reviewing production after failing to secure affordable power.

SA car parts group Jendamark braces for US tariff hit
South African car parts manufacturer Jendamark Automation stands to lose R750m of contracts in a US market it has built up to account for 50% of its exports, its operations director told Reuters. The 40-year-old company based in Gqeberha builds automated assembly lines for catalytic converters, engines and axles for automotive customers such as BMW and Mercedes-Benz among others. But like global carmakers and suppliers far and wide, they have been hit hard by US tariffs. 'As it stands now, we've got about R750m of deals with our American customers that (we're) at risk of losing,' Siegfried Lokotsch said. 'I don't know if they're going to still buy the lines from us. We thought we were going to get the orders, we were in a good position ... In my mind, they're gone (the contracts) because they've (the tariffs) just gone up.' About 85% of Jendamark's business in South Africa is for export, with 50% of that to the US, where it also has an office. Jendamark is looking for new contracts in other markets, such as Saudi Arabia, but the company has its work cut out to replace the US business it expects to lose. 'To find a new market and to understand how they operate in the country and where the opportunities are is not something that just happens overnight,' he said.
