Ivanhoe Mines (TSX: IVN) has confirmed operational recovery trajectories that will drive a sharp uptick in DRC copper output across the second half of 2026 at its flagship Kamoa-Kakula Copper Complex in the Katanga Copperbelt. After constrained Q1 and Q2 production triggered by underground seismic events, extended Kakula dewatering works and limited underground ore development, site teams have resolved core bottlenecks to unlock expanded mining capacity for H2 2026. This projected surge in Kamoa-Kakula copper production relies on three core operational levers: accelerated underground stoping at Kamoa mine, full dewatering progress across western Kakula zones, and the planned destocking of 50,000 tonnes of pre-2026 copper concentrate inventory for smelting into saleable anodes. The mine maintains its full-year 2026 copper anode guidance of 290,000–330,000 tonnes, with nearly 60% of all annual output scheduled to be generated between July and December amid rising global copper demand from energy transition infrastructure and electrical manufacturingIvanhoe Mines.
H2 2026 Copper Production Recovery Core Metrics
Q1 and Q2 2026 operations were restricted by limited ore feed, as crews prioritised underground safety rehabilitation and dewatering following seismic-induced water ingress in late 2025. All remediation milestones are now on track to unlock sustained higher mining throughput through H2.
Table 1: Kamoa-Kakula H1 vs H2 2026 Copper Production Operational Benchmarks
| Parameter | H1 2026 Actual Performance | Projected H2 2026 Operating Profile | Key Growth Driver |
|---|---|---|---|
| Monthly ore milling rate average | 1.46Mt | 1.75–1.85Mt | 30% higher underground stoping tonnage at Kamoa |
| Monthly underground mining output | 400,000 tonnes ore | 700,000 tonnes ore | Completed Kakula western zone dewatering |
| Copper anode output share of full-year | ~42% | ~58% | Inventory destocking + smelter steady ramp-up |
| Concentrate inventory to process | 50,000 tonnes contained copper | Full H2 destocking | Feed supplement for concentrator circuits |
| Smelter operating utilisation | 50% average H1 | 75–80% H2 | Steady anode casting for Lobito rail export |
| Primary constraint resolved | Kakula underground flooding & limited development headings | No major operational bottlenecks forecast | Completed safety rehabilitation works |

The Kakula underground dewatering campaign has hit 70% completion on western zones, enabling safe resumption of high-grade ore extraction; eastern zone pumping infrastructure will finish commissioning in early Q3 to further expand mineable strike lengthIvanhoe Mines. New underground development drives at Kamoa Mine will launch full stoping operations from July 2026, delivering consistent high-grade feed to Phase 1, 2 and overcapacity Phase 3 concentrators throughout the second half of the year. The on-site 500ktpa copper smelter, Africa’s largest single copper smelting facility, will absorb stockpiled concentrate to boost anode volumes for export via the Lobito Atlantic Railway westward corridor to Angolan Atlantic portsIvanhoe Mines.
Key Operational Drivers Behind Rising H2 DRC Copper Output
The forecast rebound in Kamoa-Kakula copper production stems from four interconnected operational improvements targeted for H2 2026:
Completed Underground Rehabilitation Works: Seismic remediation and multi-stage dewatering have eliminated the main safety barrier limiting access to Kakula’s high-grade mineralised zones, unlocking continuous production stoping across western mine panels.
Expanded Kamoa Mine Development Fronts: Multiple new underground access drives entered production status in Q2 2026, lifting monthly ore mining capacity by 30% and stabilising feed grades above 3.5% copper for concentrator processingIvanhoe Mines.
Concentrate Inventory Destocking Program: 50,000 tonnes of pre-2026 copper concentrate stockpiles will be blended with fresh mined ore in H2, eliminating feed shortfalls during seasonal grid power fluctuations in Katanga.
Smelter Ramp-Up Optimisation: The direct-to-blister smelter will lift daily anode casting volumes, converting concentrate into high-purity 99.7% copper anodes that command premium pricing for European and North American offtake partners.
Logistics improvements via the Lobito Corridor also support higher H2 export capacity, cutting transit times by two-thirds versus traditional eastern African port trucking routes and removing outbound shipment bottlenecks that limited H1 sales volumesIvanhoe Mines.
Global Copper Market Strategic Significance
Against a projected structural copper supply deficit through the late 2020s, the H2 output recovery at Ivanhoe’s Kamoa-Kakula complex eases near-term tightness in refined copper feedstock markets. The DRC supplies over 70% of global cobalt plus 12% of worldwide mined copper, so operational shifts at tier-one mines directly impact benchmark LME copper pricing.
For Ivanhoe Mines, the H2 production acceleration validates its long-term mine rehabilitation investment plan, restoring investor confidence after downward 2026 full-year guidance revisions issued earlier this year. The staged ramp also creates predictable quarterly cash flow growth, supporting continued underground development and smelter optimisation capital expenditure through 2027. Industry analysts note the recovery timeline reinforces the DRC’s position as a resilient source of high-grade copper supply, offsetting production disruptions at competing South American and Indonesian copper assets in 2026.
For downstream EV, renewable energy and grid manufacturing buyers, the guaranteed H2 volume increase locks in stable medium-term copper supply from a low-cash-cost African mining complex with integrated smelting and diversified export logistics infrastructure.
Conclusion
[Image Placeholder 2: Underground mining fleet at Kamoa-Kakula copper underground workings | Figure 2 – Production stoping equipment mobilised to lift ore feed for H2 2026 copper output recovery]Ivanhoe Mines’ clear operational roadmap confirms a material uplift in DRC copper output across H2 2026, centred on full production recovery at its flagship Kamoa-Kakula copper complex. Resolved underground flooding and seismic safety constraints, expanded stoping capacity at Kamoa mine, inventory destocking and steady smelter ramp-up combine to deliver nearly 60% of the project’s full-year copper anode production between July and December. The recovery trajectory preserves the 290,000–330,000 tonne 2026 output guidance, while positioning the mine for a further jump to 380,000–420,000 tonnes annual copper anode production in 2027 as underground development programs mature fully. Global copper supply chain participants will closely track quarterly assay and anode shipment data as Ivanhoe unlocks the Katanga Copperbelt’s largest remaining tier-one copper production upside in the second half of 2026.
