Many riches underlie Canadian Prairies
Bird River
South of Rice Lake is Manitoba’s past-producing Dumbarton and Maskwa West magmatic nickel-copper deposits, which are hosted within a 2.7-billion-year-old ultramafic sill complex in the Bird River greenstone belt.
The complex also contains chromite deposits, and before chromite was found in 2008 in northwestern Ontario’s Ring of Fire (ROF), Bird River represented Canada’s only known chrome camp. Geologists are investigating whether the Bird River and ROF intrusions correlate, considering they’re the same age.
