Kamoa-Kakula Copper Complex

Overview

Kamoa-Kakula is the world's fastest-growing and fourth-largest copper mine, located on the Central African Copperbelt in the Lualaba Province of the Democratic Republic of Congo. Discovered in 2009 by Ivanhoe Mines founder Robert Friedland, the deposit was identified through systematic exploration of an area previously overlooked by colonial and post-independence geologists.

The mine achieved first production in May 2021 and has scaled with extraordinary speed. In 2024, Kamoa-Kakula produced a record 437,061 tonnes of copper, establishing itself as one of the world's fastest-growing major copper operations. The mine is targeting 520,000–580,000 tonnes in 2025. A new 500,000-tonne-per-year direct-to-blister smelter — the largest and greenest on the African continent — was commissioned in November 2025, producing 99.7%-pure copper anodes. The smelter output averaged 500 tonnes per day by January 2026. It also produces 98%-pure high-strength sulphuric acid, averaging 1,200 tonnes per day. Kamoa-Kakula is 39.6% owned by China's Zijin Mining, alongside Ivanhoe Mines (39.6%), Crystal River (0.8%), and the DRC Government (20%).

Ivanhoe has set 2026 production guidance at 380,000–420,000 tonnes of copper, with a medium-term target of exceeding 550,000 tonnes annually as the smelter ramps to its full 500,000-tonne annualised capacity. A Phase 4 expansion (Project 95) was approximately 50% complete in mid-2025 and on track for Q1 2026 completion. Kamoa-Kakula has signed a capacity agreement for 120,000–240,000 tonnes annually via the Lobito Corridor.

Operations

The Kamoa-Kakula complex operates three concentrator phases with a combined milling rate targeting 14.6 million tonnes per annum, ramping toward 17 million tonnes. Phase 1 (3.8 Mtpa) commenced in 2021, Phase 2 (3.8 Mtpa) in 2022, and Phase 3 (5 Mtpa) achieved record production and throughput in 2025.

Mining occurs underground from the Kakula, Kamoa, and Kansoko mines. Average copper grades are among the world's highest for a large-scale operation, with Kakula's western high-grade areas yielding approximately 3.5–5% copper. A mine tremor in May 2025 temporarily disrupted Kakula operations, but mining resumed in June 2025 and was restored to full rates by Q4 2025 after comprehensive dewatering.

The 500,000-tpa on-site smelter employs a one-step direct-to-blister process, converting copper concentrate directly into 99.7%-pure anodes. A 60-megawatt uninterruptible power supply protects the smelter from DRC grid fluctuations. First anode exports were expected imminently as of January 2026.

Offtake agreements cover 100% of smelter output: CITIC Metal and Zijin Mining secured 80%, with Trafigura Asia Trading acquiring the remaining 20% under a three-year agreement that included a $200 million advance payment.

Corridor Connection

The mine is located approximately 25 km southwest of Kolwezi in the heart of the Lualaba copperbelt. While Kamoa-Kakula currently exports via road and rail through Tanzania and South Africa, the rehabilitation of the Lobito Corridor rail link via Kolwezi–Dilolo–Lobito offers a potentially shorter, cheaper Atlantic export route. Kamoa-Kakula has signed a capacity agreement for 120,000–240,000 tonnes annually via the Lobito Corridor, making it the single largest committed commercial anchor for the corridor's DRC section.

Diligence Focus

Community Impact

Kamoa-Kakula employs approximately 15,000 Congolese citizens as employees and contractors, making it one of the largest private employers in the Lualaba Province. The mine has invested in community infrastructure including schools, health clinics, and road improvements in surrounding communities.

However, the mine's rapid expansion creates displacement pressures for communities near the mining concession. Artisanal miners who previously worked in the area face livelihood disruption. The influx of workers has transformed local demographics and economic patterns in communities near Kolwezi.

Benefit-sharing arrangements with local communities remain an area requiring independent monitoring. As the mine expands toward its 550,000+ tonne target, further land acquisition and community impact management will be critical.

Environmental Profile

The mine's underground mining method has a significantly smaller surface footprint than open-pit alternatives. The on-site smelter eliminates the need to truck concentrate long distances, reducing transport emissions and road damage.

Water management is a significant operational challenge. The Kakula mine experienced extensive flooding requiring multi-stage dewatering operations through 2025–2026 with 5,600 litres per second of installed pumping capacity. Discharged water is fed into settling ponds.

The smelter's sulphuric acid production creates a valuable by-product but requires careful management. Tailings storage facilities serve the three concentrators and require ongoing environmental monitoring.

ESG Assessment

Independent ESG Assessment

Our independent ESG assessment evaluates this operation's environmental management, social impact, governance quality, and disclosure transparency. Environmental assessment covers water management, waste handling, air emissions, biodiversity impacts, and mine closure planning. Social assessment examines community relations, employment practices, local procurement, benefit-sharing, and human rights performance. Governance assessment evaluates corporate transparency, anti-corruption measures, and stakeholder engagement quality.

Assessment findings are incorporated into our quarterly Corridor ESG Scorecards, providing stakeholders with comparable, independent ratings across all major corridor mining operations. Operations meeting our assessment thresholds are eligible for verified ESG ratings issued from our evidence archive — verifiable reputation signals that differentiate responsible operators from those whose ESG claims are unsubstantiated. Rating publication requires demonstrated performance, not just policy commitments.

Community Impact Monitoring

Community impact monitoring around this operation tracks the full spectrum of mining effects on surrounding populations. Employment and procurement spending quantify direct economic benefits to local communities. Environmental monitoring tracks water quality, air quality, and ecosystem health in areas affected by operations. Community consultation processes are evaluated for meaningful participation versus performative compliance. Grievance mechanisms are assessed for accessibility, responsiveness, and outcome fairness.

Our monitoring provides the independent verification that enables stakeholders — investors, regulators, civil society, and affected communities themselves — to assess whether this operation delivers the community benefits that its social licence to operate requires. Documentation is preserved on our source evidence archive, creating permanent records that support long-term accountability and prevent the revisionism that undermines community claims when corporate memory proves conveniently selective.
