EcoGraf Limited:  Epanko Pre-Development Program Delivers Outstanding Results

Epanko is positioned to become a world class graphite project located in Tanzania with the recent signing of the Epanko Framework Agreement which positions the Company to secure financing for a Final Investment Decision for the Project.

HIGHLIGHTS

• Framework Agreement signed with the Government of Tanzania (Government) on 17 April 2023 in a ceremony attended by Tanzanian President, Her Excellency Samia Suluhu Hassan
• Epanko development coincides with a strong business environment in Tanzania under the new Government with over US$45 billion⁵ of new infrastructure and investments planned
• Attractive Stage 1 financial metrics¹ to support funding program:
  • Pre-tax ungeared NPV10 of US$348m (versus US$211m)
  • Ungeared internal rate of return (IRR) 36%
  • Average annual EBITDA over the initial 10 years² of US$79m
• Rigorous process completed to update capital and operating costs, led by GR Engineering and supported by independent peer review:
  • Pre-production capital costs US$134m³
• Stage 1 Value Engineering results:
  • 'Oxide First' strategy aims to deliver a 22% increase in production capacity to 73,000tpa for minimal incremental capital cost
  • Operating costs optimised through reduced drill and blast, less rehandle and lower consumption of reagents
  • Stage 1 mine life extended to 18 years, with significant scope for additional staged extension
  • Metallurgical test work supports simpler, single line flotation circuit, reducing capital cost and de-risking the flowsheet
  • Stripping ratio for waste reduced from 0.44 to 0.27 delivering lower mining costs
  • Deferral of US$6m capital for the Fresh Ore sulphide circuit and tailings pond
• Proposed grid power connection from nearby town of Mahenge through MoU signed with Tanzanian power authority TANESCO
• Evaluation of multi-stage expansion of Epanko in progress, targeting 300,000tpa of production
• Programs commenced to finalise location for in-country mechanical shaping facility to manufacture spherical graphite for customers and EcoGraf's battery anode material purification facilities
• Following conclusion of the Framework Agreement and pre-development program EcoGraf is focused on the funding and pre-construction activities to support the Company's Final Investment Decision

The Company is pleased to report the outstanding results from a pre-development program it has undertaken to build on the extensive Bankable Feasibility Study (BFS), completed in 2017 and which was subjected to rigorous due diligence by bank appointed Independent Engineers, SRK Consulting (UK) Limited (SRK Consulting).

In completing its Independent Engineer's Report, SRK confirmed that:

• all technical areas of the proposed Epanko development have been significantly advanced to conform with the requirements of international project financing standards; and
• the Environmental and Social Management Planning and supporting impact assessments conform to relevant Tanzanian legislation, International Finance Corporation ('IFC') Performance Standards and World Bank Group Environmental Health and Safety Guidelines.

The results of the Epanko program position the Project to be a potential world class new graphite development, commencing with Stage 1 with the intention to expand and match the rapid growth forecast for battery graphite to support the global transition to clean energy.

Forward looking statements

Various statements in this announcement constitute statements relating to intentions, future acts and events. Such statements are generally classified as "forward looking statements" and involve known and unknown risks, uncertainties and other important factors that could cause those future acts, events and circumstances to differ materially from what is presented or implicitly portrayed herein. The Company gives no assurances that the anticipated results, performance or achievements expressed or implied in these forward-looking statements will be achieved.

Production targets and financial information

Information in this announcement relating to the Bankable Feasibility Study conducted on the Epanko Graphite Project, including production targets and forecast financial information derived from the production targets, included in this announcement is extracted from an ASX announcement dated 21 June 2017 "Updated Bankable Feasibility Study" available at www.ecograf.com.au and www.asx.com.au. The Company confirms that all material assumptions underpinning the production targets and forecast financial information derived from the production targets set out in the announcement released on 21 June 2017 continue to apply and have not materially changed.

The production targets referred to in this announcement are based on 45% Measured Resources, 38% Indicated Resources and 17% Inferred Resources for the 18 year life of mine. The Measured Resources, Indicated Resources and Inferred Resources underpinning the production target have been prepared by a competent person in accordance with the requirements in Appendix 5A (JORC Code). The Company has used Inferred Mineral Resources as part of the production target. There is a low level of confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised. The economic feasibility of the Project has been assessed excluding the Inferred material, confirming the use of Inferred mineralisation is not a determining factor in the viability of the Project.

Mineral resources - Competent Person Statement

The Company confirms that it is not aware of any new information or data that materially affects the information included in the Company's ASX announcement "38% Increase in the Epanko Mineral Resource" on 2 March 2023, and, that all material assumptions and technical parameters underpinning the estimates in that announcement continue to apply and have not materially changed.

Ore reserves

The Company confirms that it is not aware of any new information or data that materially affects the information included in announcement dated 21 April 2017 and, that all material assumptions and technical parameters underpinning the estimates in that announcement continue to apply and have not materially changed.
