Artisanal and small-scale mining, or ASM, is a largely informal economic sector that includes workers around the world who use basic tools to extract from the earth everything from gold and gemstones to vital metals such as cobalt, tin, tungsten and tantalum. ASM is important for several reasons.
Considering the fact that this is regarding as small-scale mining, its contribution to the social and economic development of the region is much bigger. Small-scale mining generates significant local purchasing power and leads to demands for goods and services, such as tools, equipment, food, infrastructure, and housing (see Fig. 10.5).
