The McIntyre Mines yielded a considerable amount of copper in comparison with Beaulieu Mine.
The Beaulieu Mine was a post-World War II gold mining operation near Yellowknife, Northwest Territories. 
 It entered production in October 1947, but by the end of November only 7 troy ounces (220 g) of rough gold were recovered. 
 The McIntyre also yielded a considerable amount of copper over its life.
