Samples were analyzed for ore-related trace elements and the full suite of rare-earth elements. Selected samples were also analyzed for platinum, palladium, and gold. Trace-element compositions were determined using inductively coupled plasma atomic emission spectroscopy (ICP-AES) following a four-acid digestion process. Rare-earth and additional trace-element compositions were determined using inductively coupled plasma mass spectroscopy (ICP-MS). ICP-MS samples were dissolved in acid following lithium metaborate fusion. Platinum, palladium, and gold values were obtained from a 30 g sample using inductively coupled plasma atomic emission spectroscopy (ICP-AES) following aqua-regia digestion-fire assay.
