JIKANDOR, Liberia (AP) — The announcement posted in the village has a cheerful tone: “BMMC is pleased to inform you that there will be a blast” at a mining pit nearby. Residents told visiting journalists with The Associated Press and The Gecko Project that such explosions have cracked or crumbled homes during the operations of Liberia’s largest gold miner, the Bea Mountain Mining Corporation. The journalists’ investigation into the company found multiple spills of cyanide and other toxic chemicals by its largest mine into waterways, incidents documented by Liberia’s environmental regulators in reports that were removed from public view.
