On December 8, 2011, a 41 year-old crusher operator with 8 years of experience was killed at a surface stone operation. A set of wheels was to be placed on a conveyor to transport it from the mine. A front-end loader was being used to lift the conveyor when the loader bucket suddenly dropped, allowing the frame of the conveyor to strike one of the tire assemblies. The tire assembly then shifted, striking the victim.
