Madagascar Operations and Production Update

Madagascar Operations Resumed and Production Ramp-Up Underway

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 an operational update for its Madagascar flake graphite projects.

Operational Highlights

Vatomina

•     Operations resumed on site following the completion of the fundraising at end of March 2026.

•     Extensive preparatory maintenance across the project's processing plant and mining fleet, was completed ahead of the operational restart utilising resupply deliveries which arrived at the end of Q3 2025.

•     The CEO and CFO, together with other group management personnel completed a cumulative 2 week site visit during this month.

•     Meetings were held with the Ministry of Mining to brief the minister on current operations and future potential development plans.

•     Shipments from Vatomina to port for onwards delivery to international customers has resumed during April.

Production

•     Mining has resumed from the BK6 mining area, and as has processing via Pre-Concentrate Units ("PCU"), PCU 3 and PCU 4 and the Vatomina Final Processing Plant ("FCU") is ongoing.

•     Production from PCU1 and 2 is expected to restart in first half of June  following:

o  relocation to Old Mine area, identified as within suitable proximity to new, sufficient quality mining areas; and,

o  expansion of tailings storage and water reservoir facilities.

•     Installation and commissioning of a new 3 ton per hour dryer was completed and is operational at the FCU, increasing total drying capacity to 4.5 tons per hour.

•     Ongoing stockpiling is underway at the operational and future PCU locations to establish equivalent to a month's worth run-of-mine ore  to mitigate bad weather.

•     The Company is finalising a full-year mine plan and a 12-month drilling programme to support long-term growth.

•     Spare parts inventory has been further built up in order to be ready to deal with future potential breakdowns and damage of equipment in the processing of graphite. A continuous schedule of equipment and parts resupply has been established going forward.

Fuel and Power

•     Fuel supplies have remained available despite the conflict in the Middle East. However, increased prices and currency fluctuations have meant  average fuel costs have risen by over 15% in the short term.

•     A proposal to introduce solar power generation on-site and reduce exposure to fuel prices  is under review.

Sahamamy Re-development Planning Commenced

•     A re-development plan for Sahamamy, that includes a significant hydropower capacity increase is under preparation. The Sahamamy project represents a potential additional 18,000 tpa key strategic growth asset, 8km West of Vatomina.

•     The existing applications and their status for three additional licences around the Sahamamy project and their progress were discussed in meetings with the ministry of mining over the past two weeks.

Arun Somani, CEO of Total Graphite, commented:

"We are pleased to confirm that we are progressing operations at Vatomina with preparations for ramped-up production are well underway and at an advanced stage. Whilst there is still significant work to complete, the professionalism and enthusiasm of the site team, improvements in planning and operational processes, and upgrades to equipment completed over the past year to date set us on a positive trajectory. It is positive to note demand remains robust for our flake graphite, with new customer inquiries and orders being received as customers seek to diversify their flake graphite supply chains. We look forward to providing further progress updates on our Madagascar operations and the wider Group in due course."
