Artisanal and smallscale gold mining (ASGM) is a significant part of the ASM sector and accounts for approximately 20% of global gold supply. To date, ASGM has been left largely on the margins of the formal economy with little access to formal finance—that is, finance that falls within the purview of international or national law.

Background: Mercury (Hg) is used in gold mining to extract gold from ore by forming "amalgam"a mixture composed of approximately equal parts mercury and gold. Approximately 15 million people, including approximately 3 million women and children, participate in artisanal smallscale gold mining (ASGM) in developing countries.
Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.
