Colombian miners search for gold near a gold mine that collapsed --on May 1st-- in San Antonio, rural area of Santander de Quilichao, department of Cauca, Colombia, on May 3, 2014, where independent mine workers were excavating the mine without authorization. According to official data from Colombia, 80% of the mines are illegal, do not pay taxes and do not offer insurance to workers or undergo environmental laws, and many of them are controlled by illegal armed groups and gangs.
