Resolution Copper Achieves Key Milestone with Historic Shaft
Resolution Copper has marked a significant achievement with the successful conclusion of its extensive rehabilitation and deepening project for the historic No. 9 Shaft. This project, with an investment of $200 million, plays a pivotal role in establishing one of the crucial sources of copper and minerals in the nation.
Details of the No. 9 Shaft Project
The No. 9 Shaft, initially built in 1971 by the Magma Copper Company, served efficiently as a production shaft until the mid-1990s. After refurbishment, this shaft now reaches a remarkable depth of 6,898 feet—comparable to nearly five Empire State Buildings stacked on top of each other and has a diameter of 22 feet. This positions the No. 9 Shaft as the second-deepest single lift mine shaft in the United States, following only Resolution Copper’s No. 10 Shaft.
Connection to Future Developments
The shaft has been deepened from 4,800 feet to over 6,800 feet. Currently, it connects seamlessly to the No. 10 Shaft, enhancing ventilation and providing access for forthcoming underground developments. This intricate network of underground mine workings is fundamental for advancing the next phase of the project, allowing for increased copper production that is vital for reinforcing the supply of this essential mineral within the United States.
Community Involvement and Workforce Development
Vicky Peacey, President and General Manager of Resolution Copper, expressed pride in the project, stating that the completion of the No. 9 Shaft symbolizes a substantial milestone reflecting the dedication and talent of the underground team alongside contracting partners. "American miners from local communities such as Superior, Miami, Globe, and others have come together to ensure the job proceeds safely," Peacey noted. Addressing ongoing legal challenges that could impede development, she emphasized the benefits this project could bring, including thousands of well-paying jobs and significant economic growth for rural Arizona.
Commitment to Safety
The rehabilitation project also highlighted an exceptional safety record, achieving two years without any medical injuries or lost-time incidents. Spearheaded by skilled crews, the work involved drilling nearly 14,500 feet, pouring over 560 cubic yards of concrete, and applying approximately 140 yards of shotcrete, showcasing Resolution Copper’s unwavering focus on maintaining safety standards.
Collaboration and Innovation in Mining
Redpath USA, the lead contractor for the project, played a crucial role in the reclamation efforts. Their collaboration with local companies such as Oddonetto Construction demonstrated how innovative solutions can be achieved when everyone is focused on safety and excellence. Eric Stoll, Project Manager at Redpath USA, expressed pride in their contribution to the project. Similarly, Kim Oddonetto, President of Oddonetto Construction, emphasized the importance of having a locally skilled workforce, stating that the project illustrates how the right training and opportunities empower communities and contribute to Arizona's future.
