South32 Maintains 2024-25 Production Guidance, Excluding Mozal Aluminium

South32

Diversified Miner Reports Stable Output Across Key Assets

South32 has reaffirmed its 2024-25 production guidance for most of its operations, excluding Mozal Aluminium in Mozambique due to transportation disruptions from civil unrest. The Australian-based miner continues to ramp up production across its aluminium, copper, nickel, zinc, and manganese operations despite regional challenges.

Mozal Aluminium Faces Uncertainty Amid Civil Unrest

South32’s Mozal Aluminium smelter produced 90,000 tonnes of aluminium in Q4 2024, marking a 2.3% increase from the previous quarter. However, ongoing violent protests in Mozambique have led to the withdrawal of production guidance. While production and exports remain operational, raw material transportation remains disrupted.

Aluminium and Alumina Production Remains Strong

• Brazil Aluminium (40% South32 ownership): Q4 2024 output increased 13% quarter-over-quarter to 34,000 tonnes. Production guidance remains 130,000 t/yr.
• Hillside Aluminium (South Africa, 100% ownership): Production remained steady at 182,000 tonnes, with guidance unchanged at 720,000 t/yr.
• Brazil Alumina (36% South32 ownership): Q4 2024 production rose 4.2% to 348,000 tonnes, with guidance steady at 1.35 million t/yr.
• Worsley Alumina (Western Australia, 86% ownership): Production surged 18% to 1 million tonnes after maintenance, with 2024-25 guidance at 3.75 million t/yr.

Copper, Zinc, Nickel, and Manganese Performance

• Sierra Gorda Copper Mine (Chile, 45% ownership): Payable copper production rose 10% to 24,300 tonnes due to higher grades and improved molybdenum recovery. Guidance remains 84,800 t/yr.
• Cannington Zinc Mine (Australia, 100% ownership): Zinc output surged 50% to 79,200 tonnes, driven by higher plant throughput and improved silver and lead grades. Guidance holds at 265,400 t/yr.
• Cerro Matoso Nickel Mine (Colombia, 99.9% ownership): Nickel production rose 15% to 9,900 tonnes with improved plant utilization. Guidance remains 35,000 t/yr.
• Gemco Manganese Mine (Australia, 60% ownership): Production resumed after Cyclone Megan, reaching 639,000 tonnes.
• Hotazel Manganese Mine (South Africa, 54.6% ownership): Output declined 19% to 485,000 tonnes due to a temporary shutdown at Wessels mine.

Green Aluminium Incentives and Industry Outlook

The Australian government has pledged A$2 billion in production credits to support aluminium producers transitioning to renewable energy by 2036. The Green Aluminium Production Credit will be available from 2028-29 for up to 10 years, though specific details remain undisclosed.

South32’s production stability, despite regional disruptions, positions it strongly within the evolving global metals market.
