What this note covers

  • The standard data outputs produced by the PhotonAssay™ system: assay grade, instrument precision, jar weight, jar fill and measurement flags

  • How assay grade is calculated across 1-cycle and 2-cycle services for gold, silver and copper

  • Instrument precision — how it is calculated per jar and how it relates to detection limits for each service

  • The role of jar weight and fill level in determining measurement accuracy, including a reference table showing the impact of fill factor on instrument precision across gold grades

  • A complete reference guide to PhotonAssay™ measurement flags — with definitions, descriptions and recommended operator responses for each
