    How “Small” Is Small-Scale Gold Mining?

    Small-scale gold minors in Suriname, Guyana, French Guiana and Brazil are men, women and children, who are ether locals or migrant from the neighboring countries. Small-scale mining accounts for 10-15% of the worlds gold supply. Small-scale gold mining isn’t really that small in reality. Workers employ a variety of methods and mining techniques.
