Representatives from communities impacted by mining projects in Colombia, the Philippines, Nunavut and the “Ring of Fire” region in Northern Ontario protested Monday outside the Prospectors and Developers Association of Canada’s annual conference, a large event that attracts more than 1,000 exhibitors, 2,500 investors and 23,000 attendees. The Mining Injustice Solidarity Network, organizers of the rally, explained that the Ring of Fire is a proposed project covering a 5,000 square kilometre area in Northern Ontario that’s estimated to contain massive quantities of chromite, nickel and copper, among other critical minerals’ needed for the production of electric vehicles and other “green” technologies.
