A dozen traditional gold mining sites have appeared in recent years in the province of Ganzourgou. Gold panners from all over flock there to work the sites, most often living in the greatest promiscuity, without any infrastructure for sanitation and with no access to public basic services. The miners migrate according to the discovery of new veins of gold, usually moving there from the rural areas of Burkina Faso as well as from neighbouring countries (Togo, Benin, Ghana). Between one quarter and one third of them are under 18.
