Summary

All samples were analyzed for ore-related trace elements and the full suite of rare-earth elements. In addition to the internal quality-control program at ALS Chemex, DGGS monitored analysis quality by inserting ore-geochemical-pulp standards with known compositions into the sample roster for every sample batch. 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 borate fusion. Platinum (Pt), palladium (Pd), and gold (Au) values were obtained from [...]
