Mantoverde: Capital-efficient design for a world-class copper project

Chañaral, Atacama Region, Chile
Mantos Copper
2021 – 2024

With proven experience delivering cost-effective projects under lumpsum EPC contracts, Ausenco was selected to lead the engineering, procurement, construction, and production ramp-up to nameplate for a copper concentrator plant and related infrastructure - including the expansion of the desalination plant and the tailings dam - at the Mantoverde Development Project in Chile.

The Challenge

This world-class project in the Atacama region represents a strategic development in the global copper market. It is one of two primary projects Mantos Copper currently has underway in the region, focused on increasing production, reducing costs, and extending the life of its current operations.

Mantos Copper sought a partner who had the right experience and innovation to deliver a 30,000 t/day copper concentrator plant and all related infrastructure to support and enable expanded operations with guaranteed performance and price certainty.

The Better Way

Challenging earlier iterations of the concentrator plant design, our team found a better way to achieve cost efficiencies by relocating the primary crusher, redesigning the stockpile reclaim tunnel, revising tailings handlings, and optimizing grinding and flotation processes.

By reducing earthworks excavations requirements and the overall plant footprint and building heights, we were able to reduce capital and operating costs for Mantos Copper. Our efficient and optimised design is expected to reduce the environmental impact of the project including reduced carbon emissions.

Drawing on our global expertise we assembled the strongest and most efficient team to support the 36-month project during its development. The project will be led from our Chile office of more than 500 employees with the support of our technical experts located in Australia and Canada.

Redefining what’s possible, we look forward to safely delivering an exceptional project to Mantos Copper and all of its stakeholders. Upon completion in 2024, Mantoverde will produce 110,000 t/y of copper and 33,000 oz/y of gold during the first 7 years of the project’s 20 year life.

Status (as of June 2021)

Currently 100 Ausenco team members are on the project in two main locations, Santiago and Brisbane. This number will grow to 180 by end of the third quarter in 2021. Purchase orders have been issued for all critical long-lead mechanical equipment and the 30% design review has been completed. Tenders are in the market for Bulk Earthworks and the Tailings Storage Facility construction, and the camp contractor is preparing for site mobilisation.
