Malaysia is awarded with over 33 different mineral types, comprising metallic, non-metallic and energy minerals, worth several billion dollars in economic potential. Mineral exploration is one of profitable industry in this country. In 2016, the value of non-metallic mineral produced is estimated at RM5.05 billion, whilst the value of metallic and energy minerals produced is estimated at RM1.07 billion and RM0.16 billion, respectively.
The metallic mineral sub-sector produces minerals such as gold, tin, iron-ore, bauxite, ilmenite and other associated minerals. This associated minerals are by-products of tin and gold mining such as silver, zircon, monazite, rutile and struverite. The non-metallic or industrial mineral sub-sector produce sand, silica, limestone, clays, kaolin, gravel, aggregates, feldspar and mica. Only coal is produced in the energy mineral sub-sector.
Geophysics in mineral exploration involves quantitative measurements of response or contrast in properties between rocks, structures, stratigraphy and mineralization. Specifically, the variations are either on position of objects or function of time. Interpretation highlights signal “anomaly” of mineral-related features under investigation. Anomaly is significant departure from normal pattern of background values. It must be explained geologically indicating possible occurrences of mineral deposits. Moreover, geophysical technique is quick and cost-effective path to identify subsurface objects and prioritize drill targets.
