Redpath and Newmont Complete Deepest Hoisting Shaft in Australia at Tanami Expansion 2

What's Happening?

Redpath and Newmont have successfully completed the development of the Tanami Expansion 2 (TE2) shaft at the Tanami gold mining operation in the Northern Territory of Australia. This project marks the completion of the deepest hoisting shaft in the country, reaching a depth of 1,460 meters. The completion of the concrete lining signifies a major milestone for the project. The TE2 shaft team overcame significant challenges, including poor ground conditions and overbreak issues in the lower shaft. The next phase involves equipping the shaft, which includes installing shaft furniture and developing four shaft stations. The project also involves extensive infrastructure, such as a 9 km electrical cable and 10 km of pipes.

Why It's Important?

The completion of the TE2 shaft is a significant achievement for the mining industry, as it transforms the Tanami operation into a state-of-the-art crush and hoist facility. This development is expected to increase gold production by 150,000 to 200,000 ounces annually while reducing operating costs by approximately 30%. The project not only enhances the operational efficiency of the Tanami mine but also contributes to the economic growth of the region by creating jobs and supporting local businesses. The successful overcoming of geological challenges sets a precedent for future mining projects in similar conditions.

What's Next?

Following the completion of the shaft lining, the project will move into the shaft equipping phase. This involves the installation of necessary infrastructure to support mining operations, such as shaft furniture and overhead protection. The project will also focus on mitigating water ingress through grouting campaigns. As the shaft becomes operational, it will significantly boost production capacity and efficiency at the Tanami mine. Stakeholders, including local communities and the mining industry, will be closely monitoring the project's impact on regional development and economic benefits.

Beyond the Headlines

The successful completion of the TE2 shaft highlights the importance of innovation and engineering excellence in overcoming complex geological challenges. This project underscores the potential for advanced mining techniques to enhance resource extraction while minimizing environmental impact. The development of supporting infrastructure, such as accommodation villages and water treatment plants, reflects a commitment to sustainable and responsible mining practices.
