Kabanga Nickel Project Feasibility Study overview

The Feasibility Study outlines a development plan for the Kabanga Nickel Project, focused on the construction and operation of a 3.4 million tonnes per annum underground mine and concentrator. The mine will produce a total of 52.2 million tonnes of ore (100% basis) over an 18-year life of mine, with an average grade of 1.98% nickel, 0.27% copper and 0.15% cobalt, sourced from the North, Tembo and Main zones.

Metallurgical concentrator recoveries are expected to average 87.3%, 95.6%, and 89.6% for nickel, copper, and cobalt respectively, achieved through conventional froth flotation. The concentrator will produce approximately 350,000 tonnes (dry) per annum nickel-copper-cobalt flotation concentrate containing 17.7% nickel, with only low levels of deleterious elements, at the steady-state 3.4 million tonnes per annum production rate. The high-grade nickel-copper-cobalt intermediate product will be transported to the Port of Dar es Salaam for export to international customers.

The Kabanga Nickel Project is expected to deliver industry-leading cost performance. According to benchmarking completed by CRU Group, Kabanga’s all-in sustaining costs will place it firmly within the first quartile of the global nickel cost curve, underscoring the project’s competitiveness against other nickel sulfide and laterite producers. This low-cost profile is driven by Kabanga’s high-grade nickel mineralization, strong metallurgical recoveries, and valuable copper and cobalt by-products.

The chart excludes a small volume of platinum group metals (PGM) miners that produce nickel as a by-product. In USD 2024 real terms.

The Feasibility Study estimates pre-production capital expenditures of $942 million, including 9.7% contingency, capitalized operating expenditures of $168 million, sustaining capital expenditures (including closure costs) of $1.34 billion and $42 million of growth capital.

Two years of construction is planned, followed by a four-year ramp-up to full-scale capacity for the mine and concentrator.

The capital cost, operating cost and sustaining capital cost estimates were prepared as part of the Feasibility Study and are classified as Association for the Advancement of Cost Engineering (AACE) Class 3 estimates, with an accuracy range of ±15%, consistent with the standards for a Feasibility Study under S-K 1300. These estimates are based on detailed engineering, vendor quotations and benchmarked data, supporting the declaration of Mineral Reserves and the economic viability of the Kabanga Nickel Project.

Using long-term consensus metal prices of $8.49 per pound nickel, $4.30 per pound copper and $18.31 per pound cobalt, the Feasibility Study generates an after-tax net present value of $1.58 billion at an 8% discount rate and an after-tax internal rate of return of 23.3%.

The Kabanga Nickel Project is 84% owned by Lifezone and 16% by the Government of Tanzania. All Mineral Reserves and Mineral Resources are shown on an attributable to Lifezone basis, except when indicated otherwise.

Feasibility Study confirms Kabanga as a low-cost, high-grade source of critical metals

The Feasibility Study includes an 18-year mine plan based on a detailed underground mine design, accessing Proven and Probable Mineral Reserves (see Table 2 above). Over the life of mine, the Project will produce a high-grade nickel-copper-cobalt intermediate product.

Total site operating costs are expected to average $70.10 per tonne milled, inclusive of mining, processing and general and administrative costs. On an all-in sustaining cost basis, Kabanga costs are estimated at $3.36 per pound of payable nickel in concentrate, net of copper and cobalt by-product credits.

Figure 5: Kabanga all-in sustaining cost breakdown.

Pre-production capital expenditures are estimated at $942 million, including 9.7% contingency, and covering underground mine development, concentrator construction, tailings storage facility and supporting infrastructure. The project demonstrates strong capital efficiency, with an initial capital intensity of approximately $18,800 per tonne per annum of nickel production – calculated by dividing pre-production capital expenditures by total life of mine contained nickel metal in intermediate product of 902,000 tonnes over 18 years.

Pre-production capitalized operating expenditures are expected to total $168 million. Total project capital over the life of mine is estimated at $2.49 billion, including sustaining capital, closure costs and growth capital.

The Feasibility Study confirms strong project economics under consensus long-term metal prices, including robust free cash flow, a compelling net present value and a high internal rate of return.

Figure 6: Estimated project cash flows.

In addition, the Feasibility Study demonstrates Kabanga’s strong economic resilience across a range of nickel price scenarios. Even under a $7.00 per pound nickel scenario, the Project maintains an after-tax net present value of $909 million and an internal rate of return above 17%. This resilience is underpinned by the Project’s high-grade mineralization, strong metallurgical recoveries, valuable copper and cobalt by-products, low all-in sustaining costs and high capital efficiency. At $10.00 per pound nickel, Kabanga generates an after-tax net present value of $2.3 billion and an internal rate of return above 28%.

Figure 7: Sensitivity analysis of after-tax net present value (8%).

Mine development strategy supports early execution and long-term scalability

The Feasibility Study supports an underground mine at Kabanga, designed to balance early capital efficiency with long-term operational and product marketing flexibility. Access to the underground mining areas will be established via surface declines at both the North and Tembo zones. To support efficient material movement and traffic flow, North Mine includes a second decline for most of its depth, enabling one-way travel for haulage and services and is future proofed for electrification options in the future. The lower portion of North will be accessed via a single decline. Main zone, which will be developed later in the mine life, will be accessed from underground via the North Mine infrastructure. This configuration supports a streamlined ramp-up to a steady-state production rate of 3.4 million tonnes per annum.

Figure 8: Mineral Reserves Mine design.

Mining will be executed using longhole stoping with paste backfill, supported by a robust geotechnical model and engineered for mechanized, safe and efficient extraction. Stope dimensions and sequencing have been optimized to prioritize high-grade zones, particularly in the North Mine, which is expected to contribute the majority of early mill feed. Tembo Mine will provide additional feed from Year 1, with Main Mine supplementing production in later years.

Table 4: Ore mined by zone (100% basis).

Zone	Ore Mined	Ore Proportion	Grades (%)
	(million tonnes)	(%)	Nickel	Copper	Cobalt
North	30.5	58%	2.32	0.31	0.16
Tembo	16.5	32%	1.58	0.22	0.13
Main	5.3	10%	1.25	0.18	0.09
Total	52.2	100%	1.98	0.27	0.15

The underground timeline includes a two-year development and a four-year production ramp-up period, during which critical underground infrastructure (ventilation, dewatering, backfill systems, and services) will be established. To ensure disciplined execution and cost control, the first five years of mining will be undertaken by an experienced underground mining contactor, selected through a competitive tender process. This approach enables early revenue generation while preserving flexibility for future expansion.

Figure 9: Kabanga production schedule by source.

Conventional concentrator optimized for high-grade sulfide recovery

The Feasibility Study confirms the design of a 3.4 million tonne per annum concentrator at the Kabanga Site, aligned with the underground mine’s steady-state production rate. The facility will process both massive sulfide and disseminated ultramafic ore types.

The flowsheet incorporates conventional crushing, grinding, and flotation circuits to recover nickel, copper, and cobalt sulfide minerals. The concentrator will produce approximately 350,000 tonnes (dry) per year nickel-copper-cobalt flotation concentrate containing 17.7% nickel, 2.6% copper, and 1.3% cobalt, with low levels of deleterious elements such as magnesium oxide (averaging 0.6% over the life of mine), at the steady-state 3.4 million tonnes per annum production rate.

The flowsheet is based on proven, commercially established technology and uses widely available reagents, ensuring operational reliability and metallurgical efficiency. It also includes a dedicated pyrrhotite flotation circuit to separate iron sulfide minerals from the nickel-copper-cobalt flotation tailings.

Figure 10: Simplified concentrator process flowsheet.

Nickel-copper-cobalt intermediate product produced at the Kabanga Site will be loaded in sealed reusable flexible bulk containers with a payload of 9.3 tonnes each, and transported by road and rail to the Port of Dar es Salaam for export to international customers. This secure and efficient logistics solution minimizes product loss, supports environmental safety, and enables backhaul of reagents and consumables to site.

Non-pyrrhotite tailings will be used in underground paste backfill, while pyrrhotite tailings will be stored in a lined tailings storage facility.

With its high-grade, low-impurity intermediate product, Kabanga has received strong interest from potential offtake partners. Indicative, non-binding terms have been received for 100% of the intermediate product with potential customers providing payment and delivery terms.

Figure 11: Kabanga concentrator 3D model layout.

The Feasibility Study outlines a comprehensive and sustainable tailings management strategy in line with Global Industry Standard on Tailings Management and Australian National Committee on Large Dams best practices. The non-pyrrhotite tailings will be predominantly used as underground backfill along with the crushed mine waste rock (blended at 55% non-pyrrhotite tailings / 45% crushed waste rock). The remaining non-pyrrhotite tailings and pyrrhotite tailings will be stored in a fully lined downstream constructed tailings storage facility with a leakage collection system and subaqueous deposition to mitigate oxidation. The tailing storage facility is designed to accommodate up to 50 million tonnes and will have stormwater holding capacity of a 1:10,000 annual exceedance probability, 72-hour storm event. Closure plans include a water-shedding landform and multi-layer cover system. The design has been reviewed by an Independent Tailings Review Board, Government of Tanzania regulators and other industry experts.

Tanzanian infrastructure investments strengthen Kabanga’s development platform

Tanzania has an established mining sector supported by extensive national infrastructure. Ongoing government and private sector investments are enhancing power, rail, water, and port capacity, which are expected to benefit the Kabanga Nickel Project. Key infrastructure projects include:

• The Julius Nyerere Hydropower Project (2,100 MW), now 99.8% complete.
• The Standard Gauge Railway (SGR), with cargo services already running between Dar es Salaam and Dodoma.
• DP World’s $250 million investment into the Port of Dar es Salaam, which has significantly reduced vessel docking times and enhanced cargo handling efficiency.

These infrastructure upgrades will provide a strong foundation for Kabanga’s logistics strategy, enabling efficient transport, and positioning Tanzania as a competitive hub for mineral exports and industrial growth.

At the Kabanga Site, intermediate product will be loaded into reusable flexible bulk containers under a covered facility and transported approximately 347 kilometers by road to the Isaka Dry Port using contractor-operated flatbed trucks. From Isaka, the intermediate product will be railed 894 kilometers via the Standard Gauge Railway to the Kwala Dry Port, and then travel the final 88 kilometers to the Port of Dar es Salaam via a dedicated “Port Link” rail connection.

The Standard Gauge Railway is currently under construction and is expected to be operational at Isaka by November 2026. The Kabanga logistics system is designed to handle on average 350,000 dry tonnes of intermediate product per year, with train departures every 48 hours and a typical payload of 1,860 tonnes per train.

Aligning with leading international ESG frameworks

Lifezone is committed to the responsible development of the Kabanga Nickel Project, aligning with both Tanzanian regulatory requirements and internationally recognized environmental, social and governance (ESG) standards. The project operates within the legal framework of the United Republic of Tanzania, complying with national laws related to environmental protection, social impact management, land access, resettlement, and permitting.

In addition to national requirements, the project seeks alignment with leading international ESG standards and frameworks, including the International Finance Corporation Performance Standards, the Equator Principles, the Global Industry Standard on Tailings Management, and guidelines issued by the Australian National Committee on Large Dams and the International Council on Mining and Metals.

Comprehensive Environmental and Social Impact Assessments have been completed for the Kabanga Site and the Resettlement Sites, with approval certificates granted by Tanzania’s National Environment Management Council, both of which have been updated to meet international standards. Updates to the Environmental and Social Management Plan have been completed to reflect increased plant throughput and tailings storage requirements, and are awaiting Tanzania’s National Environment Management Council approval.

Figure 14: Signing of compensation agreements by a Physically Displaced Household, facilitated by Ramson Msemakweli, Resettlement Lead, June 2024.

The Kabanga Nickel Project will need to acquire 4,073 hectares of land located within the Special Mining Licence area, and implement a Resettlement Action Plan to manage land acquisition and resettlement. The current Resettlement Action Plan (May 2025), which aligns with the International Finance Corporation Performance Standard 5, outlines a comprehensive framework for resettlement implementation including compensation strategies, stakeholder engagement, and livelihood restoration. It aims to restore, and where possible, improve, the quality of life for physically and economically displaced households.

As of July 2025, approximately 96% of cash compensation agreements have been paid, with clear steps to enable the project to begin construction of resettlement housing and relocation activities across seven resettlement host sites.

The Resettlement Action Plan is supported by a Resettlement Stakeholder Engagement Plan and a Resettlement Working Group, ensuring inclusive, transparent consultation with affected communities.

Advancing economic growth and industrial development in Tanzania

The Kabanga Nickel Project is expected to deliver lasting economic benefits for Tanzanians through job creation and training, infrastructure investment and domestic value addition. It aligns with the Government of Tanzania’s goals for industrialization and participation in the global clean energy transition.

The Framework Agreement signed with the Government of Tanzania in 2021 outlines an equitable Economic Benefit Sharing Principle. This ensures that income generated by the project is shared between Kabanga Nickel Limited and the Government, on an economic basis, through dividends, taxes, royalties, duties and levies. The Agreement reflects a strong alignment with national development priorities and community upliftment.

At steady-state operations, the Project will employ approximately 1,090 people, with 91% of roles projected to be filled by Tanzanian nationals. The workforce strategy includes skills development, localization planning and engagement with the Department of Labour to ensure compliance with national employment regulations. Thousands of additional indirect jobs are anticipated through local supply chains and service providers.

The proposed Kahama Refinery, located in the Buzwagi Special Economic Zone, remains an important strategic component of Lifezone’s vertically integrated development plan, but it has not been included in the scope of the Feasibility Study.

Comparison to the June 2025 Initial Assessment

The completion of the Feasibility Study marks a significant milestone in the development of the Kabanga Nickel Project, building on the foundation established by the June 2025 Initial Assessment. While the Initial Assessment evaluated a fully integrated development concept that included mining and concentrate production at Kabanga followed by hydrometallurgical refining at Kahama, the Feasibility Study only focuses on the underground mine and concentrator. The Feasibility Study provides a more detailed assessment of the project’s technical and economic viability, while continuing to develop the potential for downstream processing in a future phase to produce beneficiated products that meet the market’s needs.

The Initial Assessment is preliminary in nature and includes economic analyses that incorporate Inferred Mineral Resources, which are considered too speculative geologically to be classified as Mineral Reserves. There is no certainty that the results of the Initial Assessment will be realized.

Looking ahead

With the completion of the Feasibility Study, the Kabanga Nickel Project is advancing into execution readiness. Lifezone is now focused on progressing the remaining technical and commercial workstreams required ahead of the Final Investment Decision. Key priorities include finalizing critical path permitting and progressing competitive tender processes for contract mining, bulk earthworks and resettlement housing to establish execution certainty and finalize pricing.

Additional technical work is planned to further de-risk the mine plan, confirm infrastructure design and prepare for early works execution. This includes advancing detailed underground mine design, refining ventilation systems and completing procurement planning for long-lead items.

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