Mozambique Mining Projects Development Update

Total Graphite plc (TGR.L), the specialist flake graphite company and supplier of the critical mineral for the global energy transition, is pleased to provide a development strategy update and next steps  for its natural graphite assets in Mozambique.

Mozambique Next Steps

·    The Company is in the process of identifying and engaging with consultants to update the earlier completed Definitive Feasibility Study ("DFS") and Value Engineering Study ("VES") of the Montepuez project, completed by the previous owners (ASX-listed "Battery Minerals Ltd", now known as "Waratah Minerals Ltd") of the project in 2017.

·    The planned updated studies are expected to:

o  Revalidate project economics using current cost and pricing assumptions

o  Assess a potentially lower capital intensity, phased development strategy

o  Support engagement with potential offtake and strategic partners

o  Enhance the basis for future project financing discussions

o  Inform the Group's longer-term ambition to develop a downstream graphite processing capability

·    The Company plans to commence similar feasibility study workstreams for the Balama Central project later in the year.

·    A site visit is planned in early May to review the status of the site and evaluate safety for future visits and onsite work to recommence.

Montepuez VES and DFS Recap

Following the Montepuez DFS published in February 2017, a VES was published in October 2017 to re-orient development of the project with an alternative approach that would implement a pragmatic modular development plan, via construction across two 50,000 tons per annum production modules.

Highlights of the VES to potentially increase the financial returns from the Montepuez Graphite Project in Mozambique contained findings that included:

·    Capex reduced to US$42.3m from US$126m

·    Opex reduced to US$337/t from US$422/t

·    Payback cut to less than two years from 4.75 years

·    Grade increased to 12% total graphitic carbon (TGC) from 8.8% TGC

·    Initial flake production rate would be reduced to 45-50ktpa from 100ktpa

·    Mine life greater than 10 years.

·    Concentrate grade increased to 96.7% TGC from 96%

·    Concentrate recoveries increased to 80% from 73%

A summary of the key Montepuez Value VES findings (compared to the February 2017 DFS findings) are shown below*:

*Indicative figures only subject to review and update by newly commissioned studies planned

Notes to table

1.          Based on the Ore Reserve released by the Battery Minerals Ltd (now Waratah Minerals Ltd) to ASX on 15 February 2017 - First 10+ years at 12% TGC and then next 10+ years at 7-8% TGC

2.          Total cash costs FOB Pemba - all site costs plus transport, excluding royalties

3.          The previous owner used US $798/t as a long-term basket price for it's concentrate in the Feb 2017 DFS.  Current Independent market commentators supported by our detailed market analysis indicates long term basket price in a range US $500-650/t. Total Graphite will continue to use conservative long-term pricing assumptions while pursuing operating costs in the lower quartile of global operations.

A summary of the key economic outcomes of the 2017 Montepuez DFS, are set out below:

*Indicative figures only subject to review and update by newly commissioned studies planned

·    Construction and early works commenced at the Montepuez project under the previous owners in 2018.

·    Currently on-site exists a 100-person base camp, a mobile crusher, power generation units and ancillary infrastructure, which will be leveraged and incorporated as part of the planned updated development studies to support future potential project financing initiatives.

·    Items in place and work to date on site will be inventoried for incorporation as part of the newly commissions studies planned.

Mozambique Flake Graphite Overview

The Company holds two world-class, high-grade, hard rock flake graphite projects in northern Mozambique's Cabo Delgado province: the Montepuez and Balama Central projects (the "Mozambique Projects").

·    Combined, the two assets hold over 13 million tons of contained graphite at an average grade above 8% TGC. The latest mineral resources statements for each project below, as updated in early 2025 by the original Competent Person and reported in  the Competent Persons Report as at 30 September 2025, were published within the Prospectus in late March 2026.

·    In updating the DFS for the Montepuez project, the Company will evaluate alternative development scenarios, aimed at reducing the upfront capex and introducing optimisations developed from recent projects.

·    It is noted that there remains significant exploration potential across both the Montepuez and Balama Central projects.

Arun Somani, CEO of Total Graphite, commented:

"It is important for the overall development of the Group to continue progressing our significant, world-class assets in Mozambique to support large scale offtake opportunities which currently exist into the energy transition sector. The large-scale assets also hold potential to supply future downstream production assets of the Company. We look forward to engaging with consultants to support the planning and future implementation of newly commissioned studies which align with the vision for Total Graphite to become a globally significant, vertically integrated natural graphite company, and further updating the market as we progress."
