The project consisted of converting the production ore hoisting system, used to hoist ore from the underground workings to the surface, into a hoisting and conveyance system to add the capability to convey backfill material from the surface to the underground storage bins.
The scope of work included removal and repair of existing structures and systems that were planned for reuse in the aggregate hoisting system, constructing a 200-ton bin, excavating a wood cribbed raise, slashing the raise to expand it to the final dimensions of 11 feet by 10.5 feet, installing a dump chute in the raise, and installing a conveyance system from the dump chute to the storage bin.
