The Perth Mint Refinery

Helping Australian gold shine on the world stage.

Australia is the second largest producer and the largest exporter of bars manufactured from newly mined gold doré in the world.

With the capacity to process in excess of 700 tonnes of gold per annum, The Perth Mint operates one of the biggest and most efficient refineries in existence, refining more than 92% of Australia’s gold production together with gold sourced from countries within the Asia-Pacific region. We are also the refiner of choice for gold jewellery and other secondary metal obtained from within Australia and across Asia. 

As a fully integrated, innovative precious metals enterprise, we service and promote the Australian gold industry by developing and nurturing the markets for refined gold, silver and platinum products across the globe. Specifically, gold, silver and platinum bullion and highly sought after collectable coins.

The Perth Mint is the only Australian refiner accredited for both gold and silver by the London Bullion Market Association (LBMA). As a certified refiner, weight master and assayer with the LBMA, our customers have confidence in the stated weight, purity and integrity of all Perth Mint products.

We are also one of only a few global precious metal refiners accredited by all five of the world’s major gold exchanges: London Bullion Market Association (LBMA), New York Commodities Exchange (COMEX), Shanghai Gold Exchange (SGE), Tokyo Commodities Exchange (TOCOM), and the Dubai Multi Commodities Centre (DMCC). These accreditations ensure that Perth Mint branded bars are internationally tradable and cements our reputation as a global leader in the precious metals industry.

With state-of-the-art facilities located in Perth, we employ four main refining processes:

  • Miller chlorination
  • Electrolytic gold refining
  • Aqua regia digest refining
  • Electrolytic silver refining

The combination of these processes ensures the most cost effective treatment of gold and silver from mines, industrial secondary metal, jewellers' lemels, and other types of high and low grade material.
