Resolution Copper (55% Rio Tinto; 45% BHP) has confirmed that rehabilitation work at its No 9 Shaft is on track for completion in 2019. Then the company expects No 9 Shaft to be deepened and connected to No 10 Shaft in 2021.
The historic No 9 shaft was originally constructed in 1971. The project is rehabilitating the shaft, sinking it to approximately 7,000 ft, and linking it with the newer No 10 shaft, which was completed in 2014. 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.
