Illegal Gold Represents 20 Percent of Peru’s Gold Exports

Illegally-mined gold represents about 20 percent of Peru’s overall exports of the precious metal, according to tax agency Sunat.
Illegal gold mining has taken off over the past decade in the Madre de Dios basin  and has been the source of mercury pollution in indigenous communities, whose fish are now contaminated, and has caused deforestation of thousands of hectares of the Amazon rainforest.
