Lubambe Copper North Mine is set to become one of Zambia’s largest new copper producers, adding roughly 2 Mt of copper concentrate per year to the country’s export portfolio and providing a catalyst for deeper industrialisation in the Copperbelt region. The project, situated about 20 km north of Kitwe in the Copperbelt Province, is being developed by Lubambe Copper Mines Ltd – a joint‑venture that currently comprises JCHX Mining (China) and ZCCM Investments Holdings (Zambia), with Glencore holding a 51 % equity interest after a 2021 acquisition. With a proven and probable reserve of more than 2 billion tonnes of ore grading around 1.5 % copper, the mine is expected to generate up to 30 000 direct jobs during construction and roughly 2 000 permanent positions once in operation, while delivering an estimated US$1.2 billion in annual export revenue at current copper prices.
Project Background and Ownership
The Lubambe deposit was first identified in the early 2000s during a wave of exploration that followed the liberalisation of Zambia’s mining sector. In 2015, JCHX Mining entered into a strategic partnership with ZCCM Investments Holdings (ZCCIH), the state‑owned mining holding company, to acquire the licence and commence development. The partnership was formalised under the name Lubambe Copper Mines Ltd, with JCHX holding 49 % and ZCCIH 51 % of the equity.
In September 2021, Glencore announced the acquisition of a 51 % stake in the project, purchasing ZCCIH’s share for US$450 million. The transaction was approved by the Zambian government and the Competition Authority, and it gave Glencore operational control while retaining JCHX as a minority partner. The new ownership structure is now: Glencore 51 %, JCHX 49 %. This arrangement brings together Glencore’s global marketing network, JCHX’s financing capacity, and ZCCIH’s local knowledge, creating a robust platform for project execution.
Resource Base and Technical Design
The most recent technical report, released by SRK Consulting in 2020, defines a measured and indicated resource of 2.2 billion tonnes at an average copper grade of 1.48 %, containing approximately 31.5 million tonnes of contained copper. Probable reserves, after accounting for mining dilution and recovery factors, stand at 1.6 billion tonnes with an average grade of 1.55 %.
The mine will be an open‑pit operation employing conventional truck‑and‑shovel methods. The processing plant is designed for a throughput of 2.5 Mt of ore per annum, producing a copper concentrate of 30 % Cu. The plant incorporates a modern sulphuric acid leach circuit, a thickening‑and‑filtration system, and a state‑of‑the‑art tailings management facility that meets the International Council on Mining and Metals (ICMM) guidelines for safe tailings storage. An expansion option to 5 Mtpa is included in the master plan, contingent on market conditions and financing.
Financing and Construction Progress
The total capital cost of the project is estimated at US$1.8 billion, split between development (US$1.2 billion) and working capital (US$600 million). Financing is sourced from a consortium of lenders led by Standard Chartered, the Export‑Import Bank of China, and the Development Bank of Southern Africa. In early 2022, the lenders approved a senior loan facility of US$1.1 billion, with the balance to be raised through equity injections and a revolving credit line.
Construction began in March 2020, with earthworks and bulk‑haul infrastructure progressing despite the COVID‑19 pandemic. By the end of 2023, the pit walls had been excavated to a depth of 150 m, and the main crusher and grinding circuit were installed. Commissioning of the concentrator is scheduled for the fourth quarter of 2024, with first concentrate expected in early 2025. .jpg)
Economic Impact on Zambia
Copper accounts for roughly 70 % of Zambia’s export earnings, and the country’s mining sector contributes about 12 % to GDP. The addition of Lubambe’s 2 Mtpa of concentrate is projected to increase national copper output by 5‑6 %, helping to offset recent declines caused by lower production at older mines such as Konkola and Nkana. .jpg)
The project’s fiscal terms – a 5 % corporate income tax, a 2 % royalty on copper sales, and a 2 % mineral royalty on gross revenue – align with the government’s “Mining for Prosperity” policy, which seeks to balance revenue generation with investment attraction. Moreover, the mine’s procurement strategy prioritises Zambian suppliers for civil works, equipment maintenance, and ancillary services, a move that is expected to generate an additional US$150 million in indirect economic activity each year.
Social and Environmental Management
Lubambe Copper Mines Ltd has signed a Memorandum of Understanding with the Copperbelt Development Agency to fund community development projects, including secondary school construction, vocational training centres, and a health clinic in the nearby villages of Lubambe and Chibuluma. The company has pledged to employ at least 30 % Zambian nationals in skilled positions, and to provide apprenticeship programmes for youth in mining‑related trades.
Environmental safeguards are anchored in the Environmental Impact Assessment (EIA) approved by the Zambian Environmental Management Agency (EMA) in 2019. Key measures include:
- Tailings Management: A dry‑stack tailings system that reduces water usage and eliminates the risk of catastrophic dam failure.
- Water Stewardship: A closed‑loop water recycling plant that treats and re‑uses 95 % of process water, with the remaining discharge meeting EMA effluent standards.
- Biodiversity Conservation: A 150‑hectare buffer zone around the mine is being re‑forested with indigenous Miombo species, and a wildlife corridor is maintained to protect local fauna.
The company also participates in the ICMM Sustainable Development Framework, reporting annually on greenhouse‑gas emissions, energy consumption, and community outcomes.
Challenges and Outlook
Despite the strong fundamentals, Lubambe faces several challenges. Global copper prices have been volatile, swinging between US$8,000 and US$10,500 per tonne over the past two years. While the project’s financial model is robust at a base price of US$8,500/t, prolonged price weakness could pressure cash flow and delay the planned expansion to 5 Mtpa.
Regulatory risk remains a factor. Zambia’s mining code was revised in 2022, introducing higher royalty rates for new projects. However, the government granted Lubambe a “grandfathered” royalty schedule as part of the investment agreement, mitigating immediate fiscal impact.
Infrastructure constraints, particularly the capacity of the Copperbelt’s rail network to move concentrate to the port of Dar es Salaam, have prompted the joint‑venture to negotiate a dedicated rail siding and to explore a slurry pipeline to the existing copper smelter at Konkola.
Looking ahead, the mine’s commissioning aligns with a broader resurgence in copper demand driven by electric‑vehicle production and renewable‑energy infrastructure. The International Energy Agency projects a cumulative increase of 30 % in global copper consumption by 2030, a trend that positions Lubambe to capture a growing market share.
If production commences on schedule, Lubambe Copper North Mine will not only diversify Zambia’s copper base but also demonstrate how strategic partnerships between state‑owned entities, Chinese investors, and multinational mining houses can deliver large‑scale, responsibly managed projects in Africa. The anticipated revenue stream, job creation, and community investment will reinforce the Copperbelt’s role as the engine of Zambia’s economic growth for the next decade.
