81% of the Kabanga Mineral Resource Tonnage is Now in Higher Confidence Measured and Indicated Categories

Multiple Exploration Opportunities Identified to Add High-Grade Mineralization

Lifezone Metals Limited's (NYSE:LZM) Chief Executive Officer, Chris Showalter, is pleased to announce the significant addition of high-grade nickel, copper and cobalt Mineral Resources to the Measured and Indicated categories at its Kabanga Nickel Project, located in north-west Tanzania. The December 2024 Mineral Resource Update is detailed in a Technical Report Summary, which has been filed on EDGAR.

The Kabanga Nickel Project is 69.713% owned by Lifezone Metals, and all Mineral Resources are shown on an attributable to Lifezone Metals basis and do not represent the total resource tonnage.

Highlights:

• Attributable Measured and Indicated Resources total 46.8 million tonnes grading 2.09% nickel, 0.29% copper and 0.16% cobalt (2.62% nickel-equivalent – 1.2 million tonnes contained nickel-equivalent).
• Plus, attributable Inferred Resources totaling 11.3 million tonnes grading 2.08% nickel, 0.28% copper and 0.15% cobalt (2.59% nickel-equivalent – 0.3 million tonnes contained nickel-equivalent).
• 3.3 million tonnes attributable to Lifezone with an average grade of 3.00% nickel (3.26% nickel-equivalent) for 98,000 tonnes attributable contained nickel have been added to the Measured and Indicated categories compared to the previous November 2023 Mineral Resource Update.
• 81% of Kabanga's Mineral Resource tonnes are now classified as the higher confidence Measured and Indicated categories relative to Inferred. Only Measured and Indicated Resources can support the conversion to Proven and Probable Reserves.
• The nickel-equivalent formula and cut-off grade calculation has been revised to reflect updated assumptions and technical parameters, increasing to 0.73% nickel-equivalent (NiEq24) for the massive sulfide domain and 0.77% NiEq24 for ultramafic, compared to 0.58% nickel-equivalent (NiEq23) previously.
• Kabanga's largest mineralized zone, the North Zone, has had a 21% increase in contained nickel in Measured and Indicated. The North Zone represents more than 50% of Kabanga's total resources, with 24.7 million tonnes of attributable Measured and Indicated Resources grading 3.19% nickel-equivalent.
• Multiple opportunities identified to grow the current Kabanga resources, including at the Safari Link zone. High-priority regional targets include multiple identified geophysical anomalies, such as Rubona Hill.

Mr. Showalter commented: "Kabanga stands as one of the world's largest and highest-grade undeveloped nickel sulfide deposits, and today's update underscores its exceptional potential. With the addition of over 15,000 meters of new drilling data, we can refine the Definitive Feasibility Study mine plan to unlock maximum value from Kabanga's rich mineralization. Upgrading high-grade nickel, copper and cobalt Mineral Resources into the Measured and Indicated categories is a pivotal step towards converting these into Proven and Probable Reserves.

With these upgrades to Kabanga's Mineral Resources, we have identified opportunities for further enhancing the Definitive Feasibility Study. We will provide an update on the Definitive Feasibility Study timeline once we have completed these technical evaluations.

Facilitated by the Memorandum of Understanding with Japan Organization for Metals and Energy Security (JOGMEC), we are evaluating the potential for a strategic investment by a Japanese partner, alongside the sale of offtake through Lifezone's marketing rights. These negotiations are progressing well and in close coordination with our project partners. We welcome the opportunity to bring on a strategically aligned Japanese partner to further advance the Kabanga Nickel Project. In parallel, we are working with our project partners to conclude the Joint Financial Model, which remains a crucial condition for BHP's T2 investment."

Table 1: Kabanga Nickel Project Mineral Resource Update shown on an attributable to Lifezone Metals basis (69.7%), as at December 4, 2024. Detailed tables are included as an Appendix to this news release.

1. This table reports the Mineral Resources for the combined massive sulfide and ultramafic mineralization types.
2. Mineral Resources are reported exclusive of Mineral Reserves. There are no Mineral Reserves to report.
3. Mineral Resources are reported showing only the LZM attributable tonnage portion, which is 69.713% of the total.
4. Cut-off applies to NiEq24, which is derived using a nickel price of $9.50/lb, copper price of $4.50/lb, and cobalt price of $23.00/lb with allowances for recoveries, payability, deductions, transport, and royalties.
5. NiEq24 formulae are: MSSX NiEq24 = Ni + (Cu x 0.454) + (Co x 2.497) and UMAF NiEq24 = Ni + (Cu x 0.547) + (Co x 2.480).
6. The point of reference for Mineral Resources is the point of feed into a concentrator.
7. All Mineral Resources in the 2024MRU were assessed for reasonable prospects for eventual economic extraction by reporting only material above cut off grades of: MSSX NiEq24>0.73% and UMAF NiEq24>0.77%.
8. Totals may vary due to rounding.

The Kabanga December 2024 Mineral Resource Update was independently prepared by Sharron Sylvester, Technical Director – Geology at OreWin Pty Ltd and in accordance with Regulation S-K subpart 1300 promulgated by the U.S. Securities and Exchange Commission (S-K 1300). Mineral Resources are reported exclusive of Mineral Reserves. There are no Mineral Reserves to report.

The December 2024 Mineral Resource Update reflects the results of a comprehensive review of the geology and mineralogy data, resulting in a tightening of the interpretations and higher confidence in the revised interpretations. It also includes assay results from 15,265 meters of drilling which were received after the September 2023 cut-off date applied to the previous November 2023 Mineral Resource Update.

Kabanga currently comprises six identified distinct mineralized zones, namely (from south-west to north-east) the Main, MNB, Kima, North, Tembo and Safari zones, which occur over a strike length exceeding 7.5 kilometers. The five mineralized zones that contribute to the Mineral Resource Update are: Main, MNB, Kima, North and Tembo, which extend over a total strike length of 6.0 kilometers and to a depth of up to 1.7 kilometers below surface.

The North Zone is the largest mineralized zone, representing more than 50% of Kabanga's total Mineral Resources. On a standalone basis, it has 788,000 tonnes contained attributable nickel-equivalent in Measured and Indicated Resources. North Zone attributable Measured and Indicated Resources total 24.7 million tonnes grading 2.58% nickel, 0.34% copper and 0.18% cobalt (3.19% nickel-equivalent) plus attributable Inferred Mineral Resources totaling 5.8 million tonnes grading 2.62% nickel, 0.35% copper and 0.19% cobalt (3.25% nickel-equivalent).

At the North Zone, 81% of the Mineral Resources are classified as higher confidence Measured and Indicated (81% across all zones), which can support conversion to Proven and Probable Reserves. For comparison, 71% of Mineral Resources were classified as Measured and Indicated in the November 2023 Mineral Resource Update.

Table 2: North Zone ONLY Mineral Resource Update shown on an attributable to Lifezone Metals basis (69.7%), as at December 4, 2024.

The Mineral Resource cut-off grade calculation has been revised to reflect updated assumptions and technical parameters, increasing to 0.73% NiEq24 for the massive sulfide domain and 0.77% NiEq24 for the ultramafic domain. This compares to 0.58% NiEq23 cut-off grade applied to the previous November 2023 Mineral Resource Update. The metal price assumptions used for 2024 cut-off grade determination are: $9.50/lb nickel, $4.50/lb copper and $23.00/lb cobalt.

Safari Link Area and High-Priority Regional Geophysical Anomalies Provide Opportunities for Additional Upside

The Safari Link area spans a 1.4 kilometers strike length north-east of the Tembo Zone, incorporating the Safari Zone (refer to Figure 1 above and Lifezone's January 28, 2024 news release).The Safari Link area is considered to be a possible strike-extension (continuation) of the Tembo mineralization, as indicated by a Tembo-style high conductance electromagnetic (EM) geophysical anomaly that exists to the north-east of the Tembo Zone. Lifezone completed 13 drill holes in 2022–23, and there is currently approximately 850 meters of strike length that remains untested.

Previous programs of geophysical surveying have identified multiple anomalies on the Kabanga Special Mining Licence area, which include the Rubona Hill anomaly – a high-priority for future regional exploration.
