Sourdough's Strike was a labor dispute between miners and mine owners in the Yukon Territory of Canada in the late 19th century. The miners, led by the famous prospector 'SOURDOUGH' Sam Steele, were striking for better wages and working conditions. The strike was resolved when the mine owners agreed to pay the miners more money for their ORE, which was referred to as a 'LODE' (4 letters) and the ORE itself (3 letters).
