Why is the assay process so important for producers?

By choosing a refiner equipped with a technologically advanced assay laboratory, you will have assured levels of metal purity and accuracy, competitive fees and a quicker turnaround. To ensure assay accuracy we look at: 

1. Methods for precision

Accuracy in gold analysis should be within 0.015% when tested by the London Bullion Market Association (LBMA), the world’s premier regulatory body. At The Perth Mint, you can be sure we achieve this number.

2. Experience

When it comes to assay accuracy, people matter. We make sure our chemists and assayers are rigorously trained in this type of analysis as it means all the difference in maximising your return.

3. Accreditation

Our refinery meets the requirements of five global gold exchanges and are regularly audited by the LBMA. 

Guaranteed accuracy

Our accuracy in gold analysis has been tested to be within 0.001% for gold by the LBMA, the world’s premier regulatory body. Compliant with Australian Standards, our assay process has been perfected over many years, offering you complete trust in our guarantee of assay integrity.
