No. 9 shaft project
Connecting the past with the mine of the future
Work has begun to restore the historic No. 9 shaft, originally constructed in 1971. The project will rehabilitate the shaft, sink it to approximately 7,000 feet, and link it with the newer No. 10 shaft, which was completed in 2014. The restoration phase is expected to take two years, and the deepening phase will require another two years. The work is on track to be completed by early 2021.
Connecting the shafts will provide a second egress route between the two shafts as well as improve ventilation.
Projected costs for the rehabilitation, sinking and linking of the No. 9 shaft to the No. 10 shaft are approximately $200 million. Resolution Copper is committed to local economic participation, so the project will emphasize local hiring, workforce development and procurement. The four-year effort will create economic opportunities for the region and the state.
