The Perth Mint has secured the Guinness World Records title for the world’s largest gold bar, with a record-breaking bar weighing 521.2 kilograms and refined to a purity of 99.999 per cent.
The achievement was announced by the Western Australian Government, which said the project highlighted the state’s gold refining capability and the expertise of local workers involved in producing high-purity precious metals.
The gold bar was created in Western Australia using Australian Origin Gold and exceeded the previous world record by more than 200 kilograms.
More than 35 specialists from The Perth Mint’s Refinery and Assay Laboratory worked on the project, which was designed to showcase advanced refining and downstream processing within the state’s mining industry.
The bar contains gold supplied by AngloGold Ashanti Australia, BHP, Evolution Mining, Gold Fields, Greatland Gold, Newmont Australia, Northern Star, Norton Gold Fields and Pantoro.
Western Australia is one of the world’s largest gold-producing regions, and The Perth Mint has long played a central role in refining, processing and marketing Australian gold for domestic and international markets.
The state government said the project demonstrates how additional value can be created from mineral resources through local refining and manufacturing, supporting jobs and export activity.
Mines, Petroleum and Exploration Minister Daniel Pastorelli said the record reflected the skills and innovation within Western Australia’s gold industry and refining sector.
He said the achievement highlighted the contribution of workers across the gold industry and reinforced the state’s international reputation for gold production and refining.
The Perth Mint remains one of Western Australia’s best-known international brands and is recognised globally as a major precious metals institution, producing bullion products and refining gold from mining operations across Australia and overseas.
The Guinness World Records title adds to the mint’s international profile and comes at a time when governments and industry are placing greater emphasis on value-added processing and manufacturing within Australia’s resources sector.
