We’re pleased to announce the release of new Certified Reference Materials, headlined by OREAS 470–474, a new clay-hosted REE CRM series.
Sourced from the Jupiter deposit in Western Australia, this five-material suite spans 330–2009 ppm TREO + Y₂O₃ and has been specifically developed to replicate deeply weathered ionic-adsorption clay systems. The series is designed to support accurate calibration and robust QA/QC across both fusion and four-acid digestion workflows, strengthening analytical confidence in clay-hosted REE exploration and mining programs.
The February release also includes:
- A replacement SEDEX Zn–Pb–Ag sulphide ore CRM
- A replacement sediment-hosted copper ore CRM
- Upcoming Cu–Au VMS CRMs (coming soon)
