Swiss-based Glencore has invested $589 million into the expansion of the Ernest Henry Mine in Queensland. The investment aims to increase production and extend the life of the mine by transitioning the copper site from an open-pit to underground shaft mine.

“This investment in Ernest Henry has effectively added 14 years to the life of the mine to 2026,” said Glencore COO for North Queensland copper, Mike Westerman.

“We’re pleased to have the opportunity to sustain production at a higher rate, continue to support around 500 employees plus contractors and deliver ongoing benefits to the Cloncurry community and economy.”

Expansion of the mine will include a one-kilometer shaft, which is expected to drastically increase the production volume by facilitating access to deposits deep beneath the earth. Glencore expects to double annual metal production to 50,000 tons of copper and 70,000 ounces of gold in concentrate over an extended mine life, which is expected to reach 2026.  

The investment will also provide access to over 50 kilometers of underground development as well as the construction of a 75-meter headframe to accommodate the company’s hoisting system.

According to Minister for Natural Resources and Mines, Andrew Cripps, the extension of the mine will contribute immensely to the regional economy of north-west Queensland.

“The $589 million commitment to continue to grow the mine will provide a major boost to Queensland’s economy and has secured jobs that would not have otherwise existed,” said Andrew Cripps.

“The transition to underground shaft mining will see mine operations extended to at least 2026 and provide jobs for more than 500 employees and contractors.”

The investment is expected to provide a vital boost to Glencore’s copper operations.

Anglo American: FutureSmart Mining

Anglo American is reimaging mining to improve people’s lives by leveraging technology, digitalisation and sustainability for FutureSmart Mining

Anglo American’s approach to technology, digitalisation and sustainability is changing the nature of the way the company mines. These are the step-change innovations that will transform the nature of mining – how the company sources, mines, processes, moves and markets its products – and how its stakeholders experience that business. Anglo American is transforming its physical and societal footprint with FutureSmart Mining.

FutureSmart Mining

“FutureSmart Mining is our innovation-led approach to sustainable mining,” Anglo American’s Tom McCulley told Mining Gllobal. In his role as CEO for Anglo American Peru & Group Head of Projects he has overseen investment of more than $5bn at the company’s Quellaveco copper project in Peru.

“These are the step-change innovations that will transform the nature of mining – how we source, mine, process, move and market our products – and how our stakeholders experience our business. It’s about transforming our physical and societal footprint.”

Technology

Anglo is undertaking a feasibility study to assess the possibility of rolling out one of its FutureSmart technologies, Coarse Particle Recovery (CPR), at Quellaveco. “CPR crushes particles to 2.5 times larger than normal, reducing energy consumption and mill time, leading to a 20% increase in throughput and 85% water recovery - a key issue in Peru given the concerns around water scarcity,” says McCulley.

“By allowing water to release from the much coarser particles, CPR will reduce the risks associated with wet tailings and ultimately help eliminate them altogether. When combined with low cost additives, it is possible to dewater residual waste and produce dry stackable tailings. This technology remains a focus area for us as water sent to tailings facilities often represents the largest water loss at a mine.”

Digitalisation

Quellaveco is going to be the first mine to run the FutureSmart operating model from day one. Anglo’s idea is to build a stable base on which it can layer new technologies, CPR being one of them. 

“We will also be a fully digital mine, which brings us future benefits in terms of understanding and applying changes in real time,” adds McCulley. “Our trucks and our drills will be automation-ready. We have taken the approach that, when we decide to move into an autonomous operation, no jobs will be lost, but the nature of some people’s jobs will have to change.”

Sustainability

FutureSmart is a blend of technology and sustainability,” said McCulley in an interview with Global Business Reports. “If you go back to the vision and design of Quellaveco, it has really been focused on the long-term sustainability of the mine through effective use of things like water, energy and the environment. Quellaveco has been focused on technology such as automation, with digital and analytical tools all coming together. We will be looking at future technologies to bolt on as we go to ensure that we are optimizing the sustainable use of resources and remaining cost-effective.”

Quellaveco

Anglo American’s Quellaveco copper project in Peru has created 15,000 jobs during construction and approximately 2,500 jobs are planned for operations, increasing Peru’s copper production by a forecast 300,000 tonnes per year. The mine’s first copper production is expected in 2022.
