Info

security remains tight around Muzo today. And while this may discourage outside attacks, it does little to address the problem of workers swallowing stones to smuggle them offsite. 7
The Muzo emerald mining district covers an area of about 360 square km, centered about 105 km north-northwest of Bogotá, in the western foothills of the eastern branch of the Andes at about 700 metres above sea level. Local relief is less than 500 metres. It consists of three major mining centres, Muzo, Coscuez and Penas Blancas. The Muzo mine is located about 8 km west of the village of Muzo. The Chivor district is located on the eastern slopes of the Andes about 75 km east-northeast of Bogotá. The district occupies about 100 square km in very rugged country, cut by canyons 1000 metres or more deep. The Chivor mine is located at an elevation of 2300 metres above sea level. The two currently active and most important mines in the Chivor district are the Chivor and the Gachala. 8
