Multiple project development activities at Tiris

Aura Energy Limited (ASX: AEE, AIM: AURA) ("Aura" or the "Company") is pleased to provide an update on the development activities at the Tiris Uranium Project ("Tiris" or the "Project") in Mauritania, West Africa.

Following the delivery of the FEED study[1] in February 2024, the appointment of advisors to progress the financing of the project and the recent announcement regarding the 55% increase in Mineral Resources[2] at the Tiris Uranium Project in Mauritania, Aura today announces five further steps towards development of the project:

• Appointment of experienced West African project director Jan Booyse and his company, Project EQ, to lead the project development at Tiris
• Appointment of Kenmore Mine Consulting to complete a mine plan optimisation review
• Appointment of Lycopodium to oversee an optimisation and project enhancement study
• Appointment of Knight Piésold Consulting to oversee water resource drilling in the abundant and proximate Taoudeni Basin
• Highly credentialled Bruce Harvey appointed to review and update the Company's Environment Social Governance ("ESG") framework

Each of these steps supports and enhances Aura's objective of completing all required steps to finalise a mine development decision by Q1 2025.

Owners team appointed

Aura has appointed Jan Booyse and his boutique mine project owners team company, Project EQ, to undertake the owners team function for the development of the Tiris Uranium mine.

Mr Booyse brings extensive experience in project delivery in West Africa and is supported by an experienced multi-disciplinary team. Mr Booyse and Project EQ will act as Aura's owner's team.

Mine Plan optimisation

In mid-June 2024, Aura announced that Tiris' global Mineral Resources increased by 55% to 91.3Mlbs U3O8, up from 58.9Mlbs U3O8[3]. The Measured and Indicated resources also increased by 35% adding 10.3Mlbs U3O8.

The increased Mineral Resource offers the opportunity to further enhance the FEED study[4],[5] economics which are already strong and offer a US$388M NPV8, 2.5-year payback period and 36% IRR with the following potential project development scenarios:

• 2.0Mlbspa U3O8 production capacity = US$ 230M development capital (Base Case)
• 2.8Mlbspa U3O8 production capacity = US$ 83M expansion capital (from 2 to 2.8Mlbpa)
• 3.5Mlbspa U3O8 production capacity = US$ 166M expansion capital (from 2 to 3.5Mlbpa)

In June, we foreshadowed that the substantial resource increase should allow optimisation and reconfiguration of the development approach, including:

• Optimisation of the number of production units and with this the potential for reduced opex and capex
• Future expansion of the Project production rate,

each of which offer the opportunity to enhance to Project's economics.

Aura has appointed Kenmore Mine Consulting to optimise the mine plan based upon the enhanced 91.3Mlbs U3O8 Mineral Resource[6] and it is expected that this work will be completed by end of the September quarter 2024.

Lycopodium review

Recognising the opportunity presented by the expanded resource and the mine plan review and the appointment of Mr Booyse, Lycopodium's South African business ADP Group ("Lycopodium") will review the project development plan and the potential for opex, capex and schedule optimisation.

Lycopodium is ideally placed to undertake this review as they have recently successfully re-commissioned Paladin Energy's Langer Heinrich Mine in Namibia. The Langer Heinrich processing plant has a very similar design and flow sheet to the Tiris process plant. The review, will focus on opportunities to:

• Reduce the initial US$230 million capital cost of the Project
• Enhance the Project's future performance

Water resource development

Local drilling and hydrological companies have been engaged to commence development of the water resources for the Project. Knight Piésold Consulting, hydrological consultants with extensive West African experience, have been engaged to oversee the program and validate the results.

The Taoudeni Basin offers an abundant water resource located close to the project and drilling will commence within a few weeks on already identified targets (~100km south of the Project). Drilling will also further develop the C22 water reservoir (35km from the Project), while geophysics will be undertaken to further refine drill targeting.

ESG review and update

The Company has commenced a comprehensive Environment Social Governance ("ESG") review and update including an appraisal of ESG framework, policies and procedures in preparation for the development of Tiris. Specific areas of focus will include the safe handling and transport of radioactive materials to meet international standards and jurisdictional requirements. The review is being led by Bruce Harvey of Resolution88 Social License Solutions, along with specialist consultants. As a former social performance practice leader for a global mining company for eight years, Bruce has significant experience developing robust ESG frameworks in Africa and elsewhere.

As previously reported[7] the dual funding processes have commenced.

Aura MD and CEO, Andrew Grove commented:

"Each of the steps outlined above represent a significant step towards development of the Tiris Uranium Project into a globally significant uranium mine.

Jan and his team have significant expertise and capacity to support Aura with the next phase of our development.

The recent drilling results and the increase in Mineral Resources both demonstrate significant future resource growth potential at Tiris from ongoing exploration activities. The increase of Tiris' global Mineral Resources by 55% to 91.3Mlbs U3O83, was delivered at a discovery cost of only US$ 0.14 per lb U3O8.

We are confident the mine optimisation and scheduling study on the enhanced 91.3Mlbs U3O8 Mineral Resource, together with Lycopodium's review will materially enhance the compelling Project FEED[8],[9] economics of NPV8 US$388M and IRR 36% after tax.

On many fronts, the Project development is rapidly advancing, with a number of these work streams having significant potential to add value to Tiris and we look forward to keeping shareholders and stakeholders informed regarding Aura's progress."

The Board of Aura Energy Ltd has approved this announcement.
