Kediet ej Jill
Kediet ej Jill is a mountain in Tiris Zemmour, Mauritania, with the city of Zouérat on its east and Fderick at west. At tall, Kediet ej Jill includes the highest peak in Mauritania.
The mountain and its surrounding area are rich in iron deposits, thought to have been mined here since the 11th century and commercially exploited since 1952. The current mines are connected to Nouadhibou on the Atlantic coast by a 700-km long railway.
Due to the magnetic field, compasses cannot function accurately on the mountain. Similar magnetic fields allowed the discovery of other deposits in the region in the 1960s.
