D3 Energy Ltd confirms maiden methane and helium reserves at ER315 in South Africa
Independent certification by Sproule ERCE supports early Production Right submission
Reserves derived from a small section of broader acreage and fault network
D3 Energy Ltd (ASX:D3E), a gas and helium exploration company listed on the ASX 200, has reported its first certified reserves at the ER315 project in South Africa’s Free State. The reserves confirmation follows independent evaluation by global consultancy Sproule ERCE, validating both helium and methane volumes within a portion of the company’s Production Right Application (PRA) area.
This milestone underpins D3 Energy’s plan to formally submit its Production Right application well ahead of initial projections and marks an early success for the company’s exploration and development strategy across the ER315 permit.
Independent Certification Covers Initial Wells on the Western Fault Zone
The certification report pertains to approximately 15% of the ER315 permit and includes reserves linked to just 37% of the wells proposed under the current development plan. The reserve volumes are associated with 16 initial wells along the Virginia fault line, comprising three Proven Developed Non-Producing wells and 13 Proved Undeveloped wells.
This initial certification excludes additional known structures such as the Ventersburg fault line on the eastern section of the application area. That region remains classified under contingent resources and awaits further drilling and production testing.
The reserve volumes detailed in the report mark a transition from earlier contingent resource classifications, with the remainder of D3 Energy’s prospective resources across the broader acreage unchanged.
Production Application Progressing Ahead of Budget and Timeline
Following this milestone, D3 Energy has confirmed it is finalising its Production Right application. The application will be based on the PRA zone and certified reserves area, representing only a portion of the company’s broader asset base and delineated geological structures.
The certified reserves are seen by the company as a strong indicator of the viability of its geological model, which highlights key fault systems as conduits for commercial helium and methane production. The company has emphasised that the certified reserves represent only a fraction of the larger tenement portfolio, suggesting broader development scope remains across the ER315 zone.
Focus on Development Efficiency and Technical Execution
Company leadership acknowledged the significance of the reserves certification not only as a technical validation but also as a demonstration of operational efficiency. The certification was secured significantly ahead of expected timelines and within a disciplined cost framework.
The ER315 project is expected to become one of only two onshore production licence holders in South Africa once the Production Right is granted. The certification and pending application are regarded as major steps in progressing the project toward commercialisation.
D3 Energy’s current advancement underlines its growing presence in the natural gas and helium space, aligning with exploration and development trends in the emerging South African resource landscape.
