Abstract: The mineralization in Perlombongan Maju Hin Lee, is essentially hydrothermal in origin. The primary mineralization is spatially related to the exposed granite and granite-metasediment contact in the form of quartz-cassiterite-tourmaline vein swarms, tungsteniferous pyrometasomatic deposit in granite, iron-ore deposits, quartz-magnetite-chlorite veins, cassiterite-polymetallic-sulphides lode and fluorite lode.
The main geological control of the emplacement of the ore bodies is a structural one, in which the prelode fracture system in the granite; have served as channelways for the migrating mineralizing agents. The prominent fracture system are joints (110-290° and 150-330°) and faults (080-260° and 020-200°).
Supergene enrichment consisting of erratic concentrates of cassiterite in gossanous ore bodies is characterised by its highly weathered iron-stain cappings on the slope of the granite mass. Some topographically low-lying areas contained tin-rich soil cover, which could have been developed by deposition of high alluvium bearing cassiterite and/or cassiterite-bearing colluvium.
