Name of the Project
Lumwana superpit expansion project.

Location
North-Western province of Zambia.

Project Owner/s
Gold and copper mining company Barrick Gold.

Project Description
The expansion will increase Lumwana’s total copper production by more than 400%, compared with the total produced since operations started in 2009.

The project will extend Lumwana’s operational life by 17 years, until 2057, and double the capacity of the processing plant – from 27-million tonnes a year to a peak design capacity of 54-million tonnes a year. This will allow for an average copper output of 240 000 t/y over the life of the mine from a planned 52-million-tonnes-a-year process feed.

The expansion has significantly expanded mineral reserves, increasing proven and probable copper reserves from 510-million tonnes at 0.58% for three-million tonnes of contained copper as of year-end 2023, to 1.6-billion tonnes at 0.52% for 8.3-million tonnes of contained copper as of year-end 2024.

Key infrastructure developments include the expansion of existing mining operations at Chimiwungo and Malundwe, the opening of two new openpits at Kamisengo and Kababisa, and a substantial increase in mining capacity to 200-million tonnes a year in 2026 and 300-million tonnes a year in 2030.

By 2039, Lumwana is expected to reach a maximum peak mining capacity of 350-million tonnes a year, positioning it as the biggest mine in Africa by total tonnes moved. Technological advancements are central to the expansion, with plans to introduce high-level automation and modern process control systems.

The project will be self-funded by Barrick and current Lumwana operations, with an estimated payback period of about two years after completion, based on a copper price of $4.03/lb.

Planned Start/End Date
Construction is set to start in 2025.
