Artisanal and Small-Scale Mining (ASM) is mineral extraction by individuals, cooperatives, or small companies with minimal capital investment and with much use of manual labour. ASM is an important rural and peri-urban livelihood. ASM is also a dangerous workplace and for many a poverty trap where health risks are many and human rights are few.
