The Perth Mint - Gold and Silver Refiner


Australia's oldest gold refiner

The Perth Mint is the world’s largest refiner of newly mined gold and the highest volume refiner in Australia.

We process more than 90 per cent of Australia and Asia’s gold production annually, equivalent to more than 10 per cent of world gold production. With our leading-edge refining capabilities, we can process in excess of 800 tonnes of gold and 900 tonnes of silver per annum.

In fact, we’ve been a partner to the Australian mining industry for 120 years, offering the most advanced and best equipped precious metals assay laboratory in the southern hemisphere.

The world’s leading gold and silver producers trust our team to deliver quality refining at a competitive and sustainable price. We take pride in returning maximum metal to producers for every ounce refined.

We understand cash flow depends on your choice of refinery and offer prompt payment and security. Our gold refining processes and operations are fully guaranteed by the Government of Western Australia, making us the lowest risk refinery in the world. 

As a fully integrated organisation, we partner with producers to deliver quality products and services to markets for Australian gold throughout the world.
