Rukwa Project update

Helium One (AIM: HE1), the primary helium explorer in Tanzania, is pleased to provide the following update on its Rukwa Project.

Highlights

• Itumbula West-1 extended well test ("EWT") remains on track for early Q3 2024;
• Environmental and Social Impact Assessment ("ESIA") study commenced as part of the Mining Licence conversion process;
• Appointment of production facilities management company to commence a design study for a helium production plant at Rukwa;
• The Company is continuing to work with the Tanzanian Government and the Mining Commission to move the Rukwa Project towards commercialisation; and
• Expansion and strengthening of Company's technical team in order to progress the Phase III work programme

Lorna Blaisse, Chief Executive Officer, commented:

"We are very pleased to be advancing into this next stage of the Rukwa Project - Phase III. Whilst we are preparing for the next operational phase, which includes the EWT at Itumbula West-1, we are growing the team to deliver the large amount of work that is continuing in the background and that will enable us to progress the project as quickly as possible.

The ESIA will form part of the feasibility study that will be submitted to the Mining Commission in order to convert the existing Prospecting Licences ("PL") to Mining Licences ("ML"). The newly recruited team has already commenced this workstream, and we are grateful for the continued support from the Government and the Mining Commission in Tanzania, as we move the project forward in the next phase of its development towards commercialisation.

We look forward to providing further updates in due course."

ESIA study

The ESIA is part of the feasibility study which is central to the licence conversion process that is required by the Mining Commission in Tanzania. As the ESIA is expected to take approximately six months to complete, the Company has commenced the work now so that the results can align with the EWT and, upon completion of both, will then allow the Company to complete the feasibility study ahead of submitting the ML conversion application.

The Company has appointed MTL Consulting Ltd ("MTL"), a Tanzanian company, for the ESIA and will continue to work with them to compile and deliver a detailed report to the National Environmental Management Council within the necessary timeframe. As well as the ESIA study, the Company will also undertake more detailed subsurface work and plans to establish contingent resource estimates which will form part of the Feasibility Study.

Production facility study

The Company has also commenced above-ground engineering studies and, following a detailed review of several companies, has now selected one to produce a preliminary design for a production system that will be suited to the flow rates and gas composition within the Rukwa Basin.

This study has commenced with several processing facility options already being reviewed. These will include a smaller, lower rate pilot plant that would allow for early production as well as larger, modular systems that can be scaled-up. The design work will include helium liquefaction, storage and transportation with the aim of providing a well head to off-taker processing system. This would enable the Company to streamline all downstream and mid-stream activities.

EWT and future drilling update

The Company has commenced ordering the long lead items for the Itumbula West-1 EWT and is currently reviewing the merits of re-entering and deepening the Tai-3 well or pursuing a new exploration/appraisal well. Amongst other considerations, this decision will be made on the back of delivery times for the necessary equipment and the availability of third-party service companies.
