On June 18, Sarawak's Geological Department revealed the discovery of extensive mineral resources across 32 per cent of the state's land, estimated at RM1.25 trillion. These minerals include gold, rare earth, bauxite and other precious metals, with potential for further discoveries as more surveys were planned across additional land.
Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers …
