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 LBMA.
Guaranteed accuracy
Our accuracy in gold analysis has been tested to be within 0.001% for gold by 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.

Assay methods
Using some of the most advanced techniques available, we can guarantee assay integrity.

Technique to extract representative samples from well-mixed metal prior to analysis.

Preliminary screening technique to determine the gold, silver and base metal content.

Method used to separate precious metals from base metals.

Technique to determine impurities and measure purity of refined gold and silver.

Solution analysis technique to determine elemental impurities in samples.
