PN-003 PhotonAssay™ Copper Services

What this note covers

• PACU01A and PACU01 copper assay services: LDL, LOQ, grade offsets, and precision from 0.05 wt% to above 2 wt% at 72 samples/hour

• High copper service (PACU01H): upper detection limit extended to 30 wt%

• Interfering elements — germanium, praseodymium, silver, antimony, zinc, phosphorus, and nitrogen — and how each affects copper measurement

• Material characterisation requirements: when and why the PACU01A generic grade offset applies, and what triggers the tailored PACU01 service

• Moist sample handling up to approximately 30% moisture, with grades reported on an as-received basis by default
