During the 1990's there was a case in which a Canadian company acqired the rights to mine billions of dollars of gold in the United States with the payment of only a few thousand dollars. The Interior department tried to stop this but a court ruled that the Canadian company had acted within the law (1872 Mining Act), and the United States was not entitled to any further payment for the gold.
So my question is: When U.S. companies operate gold mines or other mines in Canada, do they get an equally good deal?
