From a distance, the mining site in Weregn, a borderland between Jos South and Barkin Ladi local government areas, resembles a colony of bees on a honeycomb. A constant flow of miners enter and exit the site, carrying headpans, shovels, and old Bagco bags. They are mining for tin, and once in a while, the sounds of revving motorcycles are heard. If one moves closer, one sees the miners in clusters working on different mining shafts on a perforated ground.
