Coal mining in Saskatchewan Wikipedia
In 1857, John Palliser found coal during his expeditions across southern Saskatchewan The first farmers in southern Saskatchewan also noticed this coal and burning it for heat During this period, there were no commercial mines; instead farmers would collect coal from exposed seams on the edges of riverbanks and hillsides, or dig small, shallow "gopher hole" mines in their own
