| dc.description.abstract | Mineral exploration has advanced significantly over the last four decades with the incorporation of sophisticated instrument developments into practical exploration systems. This geophysical study was conducted in the Sungai Tok Pawang locality, approximately 8 Ian southeast of Gunung Jerai, near the town of Bedong, Kedah. This area is located on land held under mining lease by the South Island Mining Company (SIMCO) and the adjacent areas. The study discusses the detailed geophysical responses of iron are deposits (in four sites) to three geophysical techniques. The aim was to detect the remnants or extensions, if any, of known ore deposits which have been mined or the possible presence of primary are material at depth. The study initially involved reconnaissance ground magnetic surveys over old mining sites and their adjacent areas namely Sites A, B, C and D. The ground magnetic survey did not locate any significant anomaly over A, B, and C. However, an lmmined area, adjacent to some old mining pools, namely site D, was prospected "vith a network of grmmd magnetic traverses c.S well as gfavity and resistivity imaging surveys. On this site a previously unlmown probable iron ore deposit was detected. Furthennore, integrated mathematical modelling (with ModelVison Pro) of the magnetic and gravity data shows a sizeable ore body with physical characteristics similar to previollsly mined deposits ill the area. The magnetic survey in this study shows that the prominent magnetic anomalies outline the extent of the bodies, while gravity data provided quantitative information such as the densities of magnetite, hematite and/or limonite (3.5 g cm-3 to 3.62 g cm-3 ) and that they differ significantly from the density of the s1m-ounding rocks. Besides, the magnetic and gravity anomalies show strong correlations with one another. The results of the elecnical imaging survey could not contribute much to the detennination of the shape and depth of the iron are deposit since they were affected by several other factors like the presence of groundwater. | en_US |
