Uranium City treasure. Door from a Eldorado Mining and Refining Limited (EM&R) truck. Due to the importance of Uranium during World War 2, the Canadian Government nationalized Eldorado to supply the United States military with uranium products. This truck probably worked at the Beaverlodge Mine (Eldorado Mine) uranium mine in the community of Eldorado, approximately 7 kilometres (4.3 mi) east of Uranium City, Saskatchewan. Beaverlodge Mine opened in 1953 and closed in 1982. Any know the make and model year of this truck?.
