Samples were analyzed for trace elements and rare earth elements using: Inductively Coupled Plasma - Mass Spectroscopy (Lithium metaborate fusion - HNO3-HCl dissolution), Inductively Coupled Plasma - Atomic Emission Spectroscopy (Fire assay - aqua regia digestion), and/or Inductively Coupled Plasma - Atomic Emission Spectroscopy (HF-HNO3-HClO4-HCl digestion). See ALS documentation for a more detailed discussion of the methodology.
