Abstract: Significant traces of osmiridium, a platinum-group metal, were found in a tin placer deposit along the Sungai Semantan near Cheroh 16.1 km (10 miles) north of Raub, Pahang, Peninsular Malaysia. The likely source of this metal is a large serpentinite body situated 6.4 km (4 miles) to the west which is drained by some tributaries of the Sungai Semantan. The presence of osmiridium further supports the view that the serpentinite bodies of the Foothills group of rocks represent an ophiolite belt of Lower Palaeozoic age.
