Society and Artisanal Mining

The breadth of society that interacts with artisanal and small scale gold mining is broader than is generally recognized. This requires that governements and civil society work harder towards making the sector safer, socio-economically sustainable, and less detrimental to the environment.

MercuryWatch and the Artisanal Gold Council, are committed to these goals.
