| Abstract | Indicator minerals of Au and PGE deposits include gold and platinum-group minerals (PGM) as well as associated metallic, oxide, and silicate minerals. The greatest advantages of precious metal indicator
mineral methods over traditional geochemical analysis of a sediment sample are that ore grains are visible and can be examined, and the method is sufficiently sensitive to detect only a few grains, equivalent of ppb-level indicator mineral
abundances, even in regions where regional rocks dilute concentrates with non-indicator
heavy minerals (Brundin & Bergstrom 1977; Averill 2001). This paper reviews indicator mineral methods applied to surface sediment sampling for Au and PGE
exploration. |
