Placer platinum-group minerals were recently found in Iaterite overlying the ophiolitic rocks in Barobo and Bigan areas, Eastern Samar, and in Malinao area, Dinagat lsland, Philippines. Results of geochemical survey for platinum-group elements (PGE) and gold in the area are presented. Field observations and geochemical analyses have detected two types of positive anomalies of PGE; one in chromitite from Samar Island, and the other in Iateritic soil at Laot in Dinagat Island. Comparison of PGE abundance in chromitite and lateritic soil with that in the host rock shows that geochemical survey of refractory PGE such as osniium and iridium is as important as that of platinum and palladium to evaluate the PGE potential in an ophiolitic environment.
