On Friday, Al-Jazeera Net will present an investigative investigation from Mauritania that clarifies the circumstances of the killing of dozens of its citizens during the past three years as a result of their gold exploration in the heart of the desert with a license from the state, but without taking into account safety conditions.

The investigation prepared by the Reporters for Investigative Journalism Arab Network, known for short as "ARIJ", explains how the dream of quick affluence has claimed the lives of 160 people in the "Tegret" and "Aklib Indore" regions, which are located in the heart of the desert.
