Review of till geochemistry and indicator mineral methods for mineral
Gold and platinum group minerals (PGMs) are recovered from the 0.01 to 2.0 mm fraction. Methods to recover and examine all indicator minerals in the silt to fine sand-sized (<0.25 mm) heavy mineral fraction, not just gold and PGMs, are starting to be more widely tested and applied (e.g. Plouffe et al. 2021; Lougheed et al. 2022).
