GeoFile 2014-06: Fine-tuning stream sediment chemistry and indicator mineral methodology in exploration for carbonatite-related REE targets, Wicheeda Lake, BC, Canada
Presented as a poster at the annual Mineral Exploration Roundup Conference (2014), Geofile 2014-6 contains the results of a stream sediment orientation survey carried out on the Wicheeda carbonatite complex, the most promising REE prospect in British Colubmia. Portable XRF was used to determine relative concentrations of pathfinder elements in stream sediment samples and indentify the +125 μm stream sediment size fraction as the most useful for indicator mineral studies. Trends observed in the pXRF data were interpreted alongside the known mineralogy of the Wicheeda carbonatite to predict indicator minerals associated with the deposit. This project received funding from Targeted Geoscience Initiative 4 (2010-2015), a Natural Resources Canada program carried out under the auspices of the Geological Survey of Canada.
