There is no ‘right’ assay – our goal is to get repeatable and precise results.
With a precise and accurate result, studies have shows that natural variance will be +/- <0.8% relative.
Bias can be significantly damaging to either party.
Assaying for precious metals is more difficult due to often low concentrations and multiple interferences.
Laboratory chemists have precious metal expertise
All assay equipment is optimised and calibrated for precious metals
Balances are calibrated by an accredited third party
All methods used are optimised for precious metals
An initial matrix evaluation assay is performed to confirm final result.
