Snapshot	The Chilalo Project consists of three open pits (Central, North and West). The DFS assumes that graphite concentrate produced at Chilalo will be transported by truck to the international port of Dar es Salaam, a distance of approximately 638km. Development-ready: • Permitted to commence construction – Mining Licence and environmental approvals in place • Framework Agreement, setting the government free-carried interest and fiscal stability, agreed with the Government of Tanzania In 2023, Evolution Energy reached an agreement with BTR New Material Group Co Ltd (BTR), which on completion, will position the Company as a vertically integrated producer of lithium-ion battery (LiB) anode materials using flake graphite from its Chilalo Project. On 31 July 2024, Evolution Energy announced that its technology partner and strategic shareholder BTR had received positive performance results from battery anode and lithium-ion battery test work conducted on bulk Chilalo samples.

Summary:

The regional geology is comprised of late Proterozoic Mozambique mobile belt lithologies consisting of mafic to felsic gneisses interlayered with amphibolites and metasedimentary rocks. The mineralisation consists of a series of intercalated graphitic horizons within felsic gneiss (siliceous and aluminous rich sediments), amphibolites (mafic sourced material) and rarely high purity marble horizons.

In the Chilalo Main deposit the core high-grade mineralisation (>5% TGC) interpretation consists of two lenses. The main footwall lens strikes towards 250°, dipping roughly 50° towards 160°, with a strike length of roughly 1.1 km from the northeast towards the southwest, and a further strike length of roughly 500 m, after a strike change to 250° at about 471280 m E with a dip roughly 40° towards 180°. The average interpreted depth is approximately 200 m below surface and the true thickness is approximately 25 m for the eastern half and 10 m for the western half. The secondary high-grade lens is interpreted to be approximately 1.1 km long in the hanging wall of the western two thirds of the main lens from roughly 471800 m E extending to the west. It is interpreted to be between 40 m in depth in the east, and 160 m in depth in the west, and between 2 m and 15 m in true thickness with a similar strike and dip to the main lens. The low-grade mineralisation (>2% TGC) lenses enclose the high-grade lenses and are in the hanging wall above them and have similar strike and depth extents over the classified portions of the model. Some of the low-grade lenses are interpreted to continue along strike to the west for approximately 800 m, but these portions of the model are not classified due to insufficient data and therefore lower confidence. These lenses are generally about 5–15 m in true thickness.

At the Chilalo North deposit, the core high-grade mineralisation (>5% TGC) interpretation consists of two lenses. The hanging wall lens strikes towards 240°, dipping roughly 45° towards 150°, with a strike length of roughly 500 m from the northeast towards the southwest. The average interpreted depth is approximately 150 m below surface, ranging between roughly 110 m on the eastern and western ends to a maximum roughly 180 m near the centre. True thickness ranges between roughly 6 m on the eastern and western extremities through a maximum of roughly 30 m near the centre.

The footwall lens has a very similar strike and dip geometry to the footwall lens but extends about 90 m below surface in the east and 120 m below surface in the west and up to about 230 m near the centre. The average true thickness of this lens is roughly 7 m in the east and 6 m in the west. The interpreted low-grade mineralisation (>2% TGC) lenses enclose the high-grade lenses or are between or in the hanging wall above them. They have similar strike and depth extents to the high-grade lenses. The average true thickness of the two larger low-grade lenses that enclose the high-grade lenses is roughly 40 m in the centre to 10 m in the east and west for the hanging wall lens, and the footwall lens is on average about 12 m.
