Peru, the world’s largest producer of cocaine, has a new booming illicit business: gold. Illegal gold mining has surged in the South American country, the world’s fifth biggest gold exporter. A new Univision Investigative report shows that the criminal organizations that traffic illegal drugs have diversified and are now in the business of trading the precious metal. “There are signs that people engaged in criminal activities, like narco trafficking and terrorism are involved in illegal gold mining,” said Tania Quispe, the Director of SUNAT, Peru’s equivalent of the I.R.S. The agency is in charge of monitoring illegal gold mining.
