Small Scale Mining. ASM refers to the “low-tech, labour intensive mineral extraction and processing found across the developing world” (Hilson and McQuilken, 2014), encompassing varying degrees of formality and legality, characterised by “low levels of environmental, health and safety awareness” (Hilson, 2002: 4), and usually located in remote rural areas (Hilson, 2002).
