Who is responsible for the toxic wast site called Iron King Mine is Arizona? I know it's a superfund site that hasn't gotten any attention in 10 years. My research tells me it was owned by a company called Coronado Minerals in 1991 (same era as Keating 5) but I can't seem to find any information re: Coronado Minerals.
