In the heart of the Congo Basin, global thirst for steel has driven miners to a vast, remote forest landscape called Tridom (Tri-national Dja-Odzala-Minkébé), which holds one of the largest untapped iron reserves on earth. Shot on location, Heart of Iron explores the complexity of mining in a region that is home to Baka and Bakola pygmy and Bantu tribes and a haven for gorillas, chimpanzees, and elephants. The iron mines promise jobs, infrastructure, and new revenues but can benefits be balanced with impacts? From ministers to miners, conservationists to community members, the film asks: How do we ensure that mining benefits the poor and conserves Tridom’s rich cultural and natural heritage?
