Assay Precision

Assaying for precious metals

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.

Key success factors in precious metals assaying

 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.
