Chromitite samples were collected from a core from the Katpal chromite mine of Sukinda chromite field
for characterization of mineralogy especially the platinum group minerals (PGM). Isotope dilution with
High Pressure Asher (HPA-ID) technique has been used in this study to evaluate its ability to determine
compositions from small quantities of sample (two grams of sample). Enrichment of Iridium group of
platinum elements (IPGE) (Ir ~ 1717 ng/g; Ru ~ 20 ng/g) at depth of ~ 35-80 m in the investigated core
suggests the presence of a strong potential zone for IPGE mineralization. The obtained data suggests
similarities with the ‘Reef-type’ mineralization.
