Once the world's richest open cut gold mine, nowadays Panguna Mine is a hole in the earth full of toxic substances and big enough for clouds to live in (see video above). Since its inception, it has been the carrot dangled by politicians and entrepreneurs to the people of Bougainville. The mine and its value to Bougainville is such a complex equation that I am only slowly coming to understand it after four years of working on my documentary project.
