Norton Gold Fields (“Norton”) is a gold producer integrating mining, processing and smelting operations. It has two operating centers: Paddington and Binduli. Norton runs Australia’s largest producing heap leach operation, with a designed annual processing capacity of 5 million tonnes. The company is one of the largest local gold producers in Australia, producing 7.9 tonnes of gold in 2025.

All of Norton’s tenements are situated within Western Australia’s world-renowned Norseman-Wiluna Greenstone Belt in Kalgoorlie, covering nearly 1,000 square kilometres, with significant exploration potential.

Current operations include open-pit mining at a rate of 14 million cubic metres per annum, underground mining at 1.4 million tonnes per annum, and processing at two plants: the Paddington plant at approximately 4 million tonnes per annum and the Binduli North plant at 6 million tonnes per annum. With ongoing debottlenecking and expansion, total ore throughput exceeded 10 million tonnes in 2025.

The 2 Mtpa expansion project at Binduli is currently under construction. Upon completion and reaching full capacity in 2026, Norton’s annual gold output will remain above 8 tonnes.

Zijin Mining acquired a 100% interest in Norton Gold Fields through two transactions in 2012 and 2015. Beginning in 2025, Zijin Mining held the mine through Zijin Gold International and now owns an 85% interest in the operation.
