Gold investigation in the Sungai Luit area, Mengapur Base Metal District, Pahang

The gold anomaly at Sg. Luit forms part of the Mengapur halo which surrounds an area of copper-molybdenum minerali zation. Follow-up geochemical survey was initiated in late 1982. A 40 square kilometre gold anomalous area was delineated . Detailed soil geochemistry, pitting and test geophysical surveys were undertaken over 6 square kilometres of the most anomalous zone. This was later extended for another 3 sq uare kilometres north westwards. Geochemical anomaly maps were obtained from residual soil data, chemical analysis of heavy mineral residue from soil and gold colour count of heavy mineral residue. Anomaly maps obtained have indicated the possible occurrence of pl acer gold within the alluvial plain of the Sg. Luit especially its interfluve with Sg. Burong and Sg. Tekoh. They also indicated that primary gold mineralization probably occurs within the vicinity of Sg. Selangor and Sg . Chembah. Preliminary deep hole hand au gering was carried out in two areas, one of which gave an indication of primary gold mineralization at depth. Primary gold mineralization in the area appears to be structurally controlled rather than lithological. The main trend of mineralization at Mengapur is northeast- outhwest. Gold mineralization at Sungai Luit probably follows the same trend. The ex tent of mineralization and it s economic potential is not known as more detail ed wo rk needs to be carried out.
