Delivering copper mining projects for the future Worley

Copper is a key player in the energy transition, helping to build wind turbines, large-scale batteries and solar panels. And while there’s a large amount of copper available, miners will need to supply more quantities from declining ore grades.

The solution could be buried deep below the surface by either moving to a mass underground mine or expanding current underground activities to reach a rich orebody.

We understand the complexity involved with delivering underground mining projects and partner with our customers to navigate the changing regulatory environment, implement new technologies, ensure safety and add value to the economic and social landscape.

Using technology to unlock value Selecting the right technology for your deposit is key to extracting value from your operations and keeping your mine profitable.

Our technology ventures group help to reduce the risk of adopting new technologies by funning pilots, tracking and testing innovations.

So, you can realize the value, quantify the savings and feel confident you’re deploying the latest advancements before anyone else.

We’ve completed more than 2,000 new energy projects globally

We’re currently implementing technology to better analyze ore bodies, using automation to extract the right materials, reduce waste and increase throughput.

For many, rich ore bodies lie just out of reach It’s estimated that by 2050, 50 per cent of the world’s copper will come from underground operations.

When you’re going down 1,000 metres below surface, it takes the right technology and subject matter experts to safely deliver something of this magnitude. These hard to access areas are not easy to design, and very few can claim competence in this space.

But for new era brownfield and greenfield copper mining projects, we are well positioned to lead.

Automating the world’s largest underground mine

Delivering one of Peru’s largest copper mines

Project El Teniente New Mine Level Project Customer Codelco Location Rancagua Region, Chile

Project Toromocho Copper Mine Customer Minerna Chinalco Location Morococha District, Peru

To keep its mine operational for the next 50 years, we helped Codelco access a new deposit by using new technologies and selecting the mine infrastructure.

Automation and remote operations were built into the design of the expansion, as well as ondemand mine ventilation for energy efficiency. Once operational, the mine will be managed remotely from a center 60 kilometres away.

We helped Minerna Chinalco deliver its first open pit mine, Toromocho, in South America.

We completed the feasibility study and provided full engineering, procurement and construction management services, and ore processing at an anticipated rate of 117,200 tons per day to produce copper concentrates.

The mine is one of Peru’s largest copper mines, producing 225,000 tons of copper annually.

Using innovative technology to plan Papua New Guinea’s biggest underground mine

Transforming an open-pit operation to one of the world’s largest underground mines

Project Wafi Golpu Customer Newcrest Mining Ltd / Harmony Location Papua New Guinea

Project Chuquicamata Underground Project Customer Codelco Location Antofagasta Region, Chile

Wafi Golpu is a proposed underground block caving copper-gold development, operating over three lifts for the life of mine.

Providing conceptual engineering services, we helped Codelco identify, study and analyze principal alternatives for ore extraction and handling in their new underground mine. We studied two options, including panel caving and block caving. Our studies identified an optimal mining rate of 140,000 tonnes per day, making the development one of the world’s largest underground mining operations. We also led the development of both the materials handling systems and infrastructure design.

We provided the pre-feasibility study and early site establishment services for the surface and underground infrastructure, extracting 30 million metric tonnes per annum of ore. We used SmartPlant design technology, rapid prototyping and building information modeling (BIM) to create a digital-project-design platform that efficiently and cost effectively prepares Newcrest Mining and Harmony for project execution.
