To craft metal tools, copper is the first metal ore players need to find. Surface native copper deposits are readily available sources of material available to players during early game stages, except for areas where the top stone layer is bauxite. In limestone areas, surface malachite deposits can be found, which is another type of copper ore.
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 …
