South32 Receives Fast‑Track US Permit for Arizona Zinc‑Manganese Mine

South32 Ltd (ASX:S32) is set to obtain a record‑of‑decision from the U.S. Forest Service authorising its $2 billion zinc and manganese mining project in Arizona on Tuesday, according to a Forest Service statement viewed by Bloomberg. The approval follows a fast‑track permitting decision made by the Trump administration, marking the first mining project to receive expedited treatment from the U.S. Department of Agriculture after the Federal Permitting Improvement Steering Council designated it for swift review.

The critical‑minerals project, located in the Patagonia Mountains about 80 kilometres southeast of Tucson near the Mexico border, contains one of the world’s largest undeveloped zinc deposits together with other key minerals essential for steel production and large‑capacity battery manufacturing, as noted by the Agriculture Department. South32 has indicated that the mine is expected to reach full production by 2029.

The fast‑track approval aligns with President Donald Trump’s second‑term objective of strengthening U.S. supply chains and reducing dependence on China for critical minerals required in consumer‑goods and advanced‑energy technologies. Market reaction showed the ASX index up 2.08% and South32 shares gaining 0.48% following the news.
