Lumwana Expansion In Full Swing As Barrick Builds Tier One Copper Mine

All amounts expressed in US dollars

LUSAKA, Zambia, July 10, 2025 (GLOBE NEWSWIRE) -- Construction of the $2 billion Super Pit Expansion Project at Barrick Mining Corporation鈥檚 (NYSE:B)(TSX:ABX) Lumwana mine is well underway, accelerating its transformation into a Tier One copper mine.

Addressing members of the media and other stakeholders here today, Barrick president and chief executive Mark Bristow said the Lumwana expansion builds on a remarkable turnaround that has seen the operation evolve from a struggling asset into a key pillar of both Barrick鈥檚 global copper portfolio and Zambia鈥檚 long-term development agenda.

鈥淲hen we reviewed the Lumwana mine in 2019, it was high-cost and underperforming. Today, it鈥檚 a growing force in African copper. With this expansion gaining momentum, Lumwana is on course to join the world鈥檚 list of large and strategically important copper mines, and a powerful driver of growth for both Zambia and Barrick,鈥� Bristow said.

The expansion will double copper production to 240,000 tonnes a year, supported by a 50 million tonne per annum processing plant. Site construction is underway, long-lead equipment orders have been placed, and infrastructure upgrades 鈥� including a new power transmission framework developed in partnership with ZESCO 鈥� are progressing to support both the mine and the wider region.

Since 2019, the mine has contributed over $4 billion to the Zambian economy through taxes, royalties, procurement and wages. More than $3.4 billion has been spent with Zambian suppliers, representing 79% of its total procurement. In Q1 of this year alone, $177 million or 81% of procurement was placed with local contractors. Today, 98% of Lumwana鈥檚 workforce are Zambian nationals, with nearly half drawn from nearby communities.

As part of an integrated development plan aligned with Zambia鈥檚 Mining and Minerals 2031 policy, the Lumwana expansion will drive the development of the Manyama township and industrial supplier park. A new regional airstrip is expected to be completed by the end of the year and a TEVETA-accredited training centre will be launched to expand Zambia鈥檚 mining skills base.

The mine is also advancing one of the country鈥檚 most ambitious environmental and carbon initiatives, with the development of a REDD+ forest conservation programme in collaboration with local chiefdoms and the Forestry Department. Covering up to 300,000 hectares, the project is designed to generate future carbon credits while supporting sustainable livelihoods, biodiversity and land stewardship.

鈥淟umwana is becoming a flagship for sustainable copper mining. It demonstrates how a world-class mine can help build an industrial ecosystem while protecting the environment and expanding economic opportunity,鈥� said Bristow.

Operationally, Lumwana is tracking well against its 2025 production guidance. Performance in the first quarter set a strong tone for the year, supported by increased plant throughput and continued improvements in open-pit efficiency. The mine retained ISO 14001 and 45001 certifications and recorded no Class 1 or Class 2 environmental incidents to date.

鈥淲e鈥檙e not just expanding a mine, we鈥檙e strengthening a partnership. Our teams are actively exploring further growth opportunities across the Zambian copperbelt, building on our recently signed Memorandum of Understanding with the Government of Zambia. Together, we鈥檙e laying the foundation for lasting economic and social development that will endure long after mining ends,鈥� Bristow said.
