By the end of 1916 the mines were being worked as much as 2,700 feet below the surface. In 1917, a cave-in at the 700-Foot shaft flooded the Treadwell, 700-Foot, and Mexican mines. Only the Ready Bullion survived and remained in operation until 1923, when lean ore caused the mine to cease operations (Redman and others, 1989).
