Snapshot	In April 2023 EcoGraf reported the results of its Epanko (Mahenge) Graphite Project pre-development program and includes updated capital cost, operating cost, graphite pricing with all the material assumptions as detailed in the Bankable Feasibility Study (dated 21 June 2017). The updated Ore Reserves of the Epanko project are based on Mineral Resources, announced on 11 March 2024, combined with the Company’s “Oxide Ore first”. Initial 18-year Life of Mine for stage 1, with additional Mineral Resources providing for a phased expansion up to 300,000tpa. Low-grade material will be stockpiled and the processing deferred to the end of the current mining schedule, extending the initial stage 1 operating period by a further 5 years, to 23 years. The Epanko Special Mining Licence (SML) application has been submitted to the Tanzania Mining Commission and is progressing well. The SML application has requested a 50-year life for the licence.

Deposit type

• Metamorphic

Summary:

The Epanko Project is hosted within a quartz–feldspar graphitic schist, part of a Neoproterozoic metasediment package, including marble and gneissic units. Two zones of graphitic schist have been mapped, named the Eastern Zone and the Western Zone. Mineralisation is believed to be the product of pre-existing carbonaceous sediments subjected to regional metamorphism induced by a north-south regional thrusting event. The graphitic schists contain between 3% and 29% total graphitic carbon (TGC).

Graphitic mineralisation is hosted within graphitic schist, which is mapped along its strike within the licence area. Total graphitic carbon is assumed to be likewise continuous with the host rock unit. Metallurgical characteristics, principally flake size, has been observed to be of a consistent nature when observed in outcrop, trench exposure and diamond drill core at numerous locations within the licence area.

The graphitic schist is open along strike and down dip in Epanko West. The Epanko East deposit is interpreted to be a recumbent fold, open along strike to the north and south. A sub-vertical shear zone offsets the stratigraphy down dip along the lower fold limb.

Mineralisation domains for TGC were not modelled.

Weathering domains representing oxide, transitional and fresh were modelled and were used during grade interpolation to constrain grade interpolation, and were allocated different density values. A zone of overburden material was modelled for Epanko East, and is barren of TGC.

Lithological domains representing schists, gneisses and marble were interpreted and modelled.

Major structural features, mainly sub-vertical shears and faults, were modelled and used to assess drill assays during preparation of the Mineral Resource estimate.

Dimensions
The Epanko West Mineral Resource estimate is approximately 3,500 m in strike, 250 m in plan width and reaches 300 m depth below surface. The Epanko East Mineral Resource is approximately 320 m in strike, 400 m in plan width and reaches 160 m depth below surface.
