Nine of Western Australia’s gold miners pooled metal into a single bar at The Perth Mint that now holds the Guinness World Records title for the world’s largest, weighing 521.2 kilograms and refined in Perth to a purity of 99.999 per cent.
The bar was made using Australian Origin Gold and beat the previous world record by more than 200 kilograms. More than 35 specialists across The Perth Mint’s Refinery and Assay Laboratory worked on it.
The gold came from AngloGold Ashanti Australia, BHP, Evolution Mining, Gold Fields, Greatland Gold, Newmont Australia, Northern Star, Norton Gold Fields and Pantoro, a list covering the miners behind much of the state’s output.
“Western Australia is recognised globally for its gold industry, but this project highlights another important part of the story – how we add value to our resources through world-class refining, advanced technology, and highly skilled people,” Western Australian Minister for Mines, Petroleum and Exploration Daniel Pastorelli said.
The Perth Mint, based in East Perth and owned by the Western Australian Government, plays a central role in adding value to one of the state’s most important resources. The record lands at a time when gold has become one of the country’s largest single exports, worth $71 billion in 2025.
“This Guinness World Records title belongs not only to The Perth Mint, but to the many Western Australians who work across our gold industry and help maintain our reputation as a global leader in gold production and refining,” Pastorelli said.
The project sits alongside the state government’s Made in WA agenda and its focus on growing local industry, skilled jobs and value-added manufacturing.
“The World’s Largest Gold Bar showcases the skills, capability, and innovation that support local jobs and contribute to our economy, while shining a spotlight on Western Australia on the world stage.”
