MARTEN FALLS, Ont. – Some facts and figures about a massive mining deposit in northern Ontario known as the Ring of Fire.

Location: An area 500 kilometres northeast of Thunder Bay, Ont., in the James Bay lowlands, in the traditional territories of several First Nations. Chromium is the Ring of Fire’s main claim to fame, but there are also proposals to mine nickel there, and hopes for copper, zinc, gold and palladium. There are about 100 mining companies with holdings in the Ring of Fire, but only 35 of them are actively exploring, and just two of them have actually proposed mining.
