Robust Initial Assessment economics for a globally significant source of nickel, copper and cobalt
A preliminary mine design, accessing Measured and Indicated Mineral Resources as well as Inferred Mineral Resources, outlines a 22-year mine plan for the project, with total underground production of 67.9 million tonnes grading 1.93% nickel, 0.26% copper and 0.14% cobalt. During the first five years of operation, the project will export a high-grade nickel-copper-cobalt concentrate while the hydrometallurgical refinery at Kahama is being developed. Once operational, the refinery will promote in-country beneficiation by producing battery-grade nickel and cobalt sulfate products and

Phased underground mine development enhances capital efficiency and operational readiness
The Initial Assessment outlines a phased underground mine development strategy at Kabanga, designed to optimize capital efficiency and support an achievable production ramp-up. The mine will be accessed via declines from two boxcuts at the North and Tembo zones. Kima zone will share access from the North decline, while the Main and MNB zones are accessed via the
Figure 6: Proposed mine design.
Mining will be conducted using longhole stoping with paste backfill, with level spacing of 25 meters and stope strike lengths ranging from 20 to 30 meters. The mining sequence prioritizes the high-grade portions of the North zone. The North and Kima zones are expected to supply approximately 65% of the total mineralized material, followed by Tembo (25%) and Main and MNB (10%). The mine design incorporates detailed geotechnical modeling, ventilation planning, and a robust backfill system to ensure safe and efficient operations.
The development schedule includes a 2.5-year construction period followed by a 2.5-year ramp-up phase, during which critical infrastructure such as ventilation raises, pumping systems, and underground services will be established. The first five years of mining will be executed by a contract mining firm selected through a competitive tender process, ensuring experienced execution and cost control during the early stages of operation.

Further Exploration Targets offer significant upside potential
The Initial Assessment Technical Report Summary also discloses an overall Exploration Target of 17.5 to 23.5 million tonnes grading 1.9% to 2.1% nickel equivalent from four high-priority Exploration Targets within the Special
The ranges of potential tonnage and grade of the Exploration Targets are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource for these target areas. It is uncertain if further exploration will result in the estimation of a Mineral Resource.

Efficient sulfide concentrate production with high recoveries at the Kabanga concentrator
The Initial Assessment outlines a conventional concentrator facility at Kabanga, designed to process 3.4 million tonnes per annum and produce a high-grade nickel-copper-cobalt concentrate. The flowsheet, comprising crushing, wet grinding, flotation and dewatering, has been developed through extensive metallurgical testwork to suit the deposit’s mineralogy, including massive sulfide, semi-massive sulfide and ultramafic-hosted zones.
The concentrator is expected to achieve average metallurgical recoveries of 87.3% for nickel, 95.7% for copper and 89.7% for cobalt. The resulting concentrate, grading approximately 17.3% nickel, 2.6% copper and 1.3% cobalt, is low in deleterious elements and well-suited for downstream refining.
The high-grade, low-impurity nature of Kabanga’s concentrate has received strong interest from potential offtake partners for both nickel concentrate and refined battery-grade products. Indicative, non-binding terms have been obtained for 100% of the concentrate produced during the first five years of operations, prior to the commissioning of the

Designed to process concentrate from the Kabanga mine, the refinery is expected to achieve average metal recoveries from concentrate of 97.2% for nickel, 93.0% for copper and 97.7% for cobalt. The flowsheet incorporates pressure oxidation, neutralization, solvent extraction, electrowinning and crystallization, enabling the designed production of approximately 50,000 tonnes per annum of nickel as nickel sulfate, 7,000 tonnes of copper cathode and 4,000 tonnes of cobalt as cobalt sulfate. All products are expected to meet stringent purity standards for use in electric vehicle batteries.

To support the Kabanga project development, Lifezone is pursuing a diversified funding strategy that includes a mix of equity, strategic partnerships, and project-level debt. Discussions are ongoing with development finance institutions, commercial lenders, and potential strategic investors. The project’s attractive economics, low operating costs and alignment with global critical minerals priorities position Kabanga as a compelling candidate for sustainable financing. Lifezone expects to finalize the funding package following completion of the Feasibility Study.
