Ring of Fire (Northern Ontario)
The Ring of Fire is a mineral-rich crescent-shaped geographical region in the James Bay Lowlands of Northern Ontario, Canada. It is approximately 5,000 square kilometres in size with most discoveries of chromite, nickel, copper, platinum group elements, gold, zinc, and palladium found in a 20 kilometre strip of land.
Potential development of mining sites, particularly "Eagle's Nest" (copper-nickel) and "Black Thor" (chromite), have been controversial in both Federal and Provincial politics since the Ring of Fire was discovered in 2007. Australian-based company Wyloo Metals is the current owner of "Eagle's Nest" and plans to construct a mine on the site in 2027, with production planned to begin in 2030. It is believed to contain more than 15.7 million tonnes of high-grade nickel with "significant" amounts of copper and platinum group metals. Ontario-based exploration company Juno Corp. is the largest private claimholder of the Ring of Fire. As of January 2025, Juno Corp. has laid claim to 4,600 square kilometres of land, including an area known as the Vespa Complex. Juno formed in 2019 with the goal of "systematically making discoveries" in the Ring of Fire and is responsible for expanding mining developments past the original "Ring" into outlying areas.
The crescent-shaped Ring of Fire is named after a song popularized by Johnny Cash.
