At the request of the King, the Royal visit to Sudbury, Ontario, on June 13, 1939, the capital of Canada’s nickel belt, was extended to allow a glimpse of the operations of the Nickel industry to be given to their Majesties, who also found time to pay a visit to the famous Frood mine of the International Nickel Co. Dressed in miner’s helmets and overalls, Britain's King George VI and Queen Elizabeth went nearly half a mile underground to the 2,800-ft level, made a short tour underground and saw at close quarters the operation of mining copper-nickel ores.
