South32 Ltd. Corporate and Market Developments – 2025

Share Buy‑Back Programme

South32 Ltd. announced daily share buy‑back activities on 18 December 2025, as reported by Investing.com and corroborated by the company’s own daily notifications on Sharenet and BusinessDay.

  • The buy‑back is conducted in accordance with the company’s share‑repurchase policy under the Corporations Act 2001 (Cth).
  • No specific amount or number of shares is disclosed in the public statements; the programme is described as a routine, ongoing exercise aimed at returning capital to shareholders.

Mozal Aluminium Smelter – Care and Maintenance Status

South32 has decided to place its Mozal aluminium smelter in Mozambique on care and maintenance, effective from March 2026. This decision follows the company’s failure to secure an affordable and reliable electricity supply for the facility.

  • The announcement was made on 17 December 2025 through several outlets (FastMarkets, BusinessDay, and Sharenet).
  • The move is expected to tighten aluminium supply in Europe, potentially supporting higher prices.
  • Mozal remains the largest aluminium smelter in Mozambique, and its shutdown has implications for the country’s industrial output and energy market.

Power Options for Hillside Aluminium

South32 and Eskom are jointly exploring post‑2031 power options for the Hillside Aluminium smelter in South Africa.

  • Studies are underway to assess future power sources, reflecting the company’s need to secure long‑term, cost‑effective electricity for its smelting operations.
  • The current power agreement with the South African government is under review as part of these efforts.

Trilogy – Alaska Mining Permitting

Trilogy, a partner of South32, is targeting a 2026 mine permitting push at Alaska’s Ambler district.

  • The initiative focuses on exploration and development activities aimed at securing necessary permits for future mining operations in the region.
  • This development is part of South32’s broader strategy to expand its mining footprint in North America.

Commodity Market Context

  • Copper prices approached record highs on 19 December 2025, with the benchmark three‑month contract on the London Metal Exchange up 0.5 % at $11,837, driven by renewed supply‑tightness concerns highlighted by Goldman Sachs.
  • South32’s portfolio includes copper, and the company’s market presence in the metals sector may be influenced by these price dynamics.
