What this note covers

  • What CRIRSCO-based reporting codes (JORC, NI 43-101, PERC, SAMREC) actually require — and why “compliance” is the wrong question

  • The correct disclosure framework for PhotonAssay™ across field sampling, laboratory preparation, assaying, and QA/QC

  • ISO 17025 accreditation, its relevance to PhotonAssay™ laboratories, and why it does not replace direct CQP verification

  • How PhotonAssay™’s non-destructive method enables CRM reuse and true analytical precision determination

  • Confirmation that PhotonAssay™ has appeared in JORC and NI 43-101 public releases since 2018
