Anson Resources has pushed forward the Definitive Feasibility Study for its Green River Lithium Project, targeting completion in January 2027 after a key engineering meeting in Las Vegas.
- DFS progressing with Sedgman coordinating engineering
- Baker Hughes handling brine extraction and transport
- Completion targeted for January 2027
- Study covers full lithium carbonate production chain
- Builds on May 2026 scoping study foundations
Engineering Collaboration Advances DFS
Anson Resources (ASX:ASN) has taken a significant step forward in its Green River Lithium Project in Utah, convening a face-to-face Definitive Feasibility Study (DFS) review in Las Vegas. The meeting brought together key engineering partners including Sedgman, which is leading the overall coordination, and Baker Hughes, responsible for wellfield design and brine extraction logistics. This collaboration aims to integrate the complex engineering components necessary for lithium carbonate production.
Sedgman, part of ACS Group, is tasked with harmonising designs, services, and equipment from various technology providers to develop a comprehensive process flow sheet and mass balance. The DFS will also deliver capital and operating cost estimates at an AACE Class 3 accuracy level, targeting a margin of error of plus or minus 25%. This level of precision is critical for advancing the project towards financing and execution decisions.
Scope Extends Across Full Production Chain
The DFS will build on the Front-End Planning Stage 1 scoping study completed in May 2026, expanding the focus to include the entire lithium production cycle. This covers extraction of lithium-rich brine, its transportation to the processing plant, and the subsequent production of lithium carbonate. Additionally, the study will address the supply of essential utilities such as electricity and water, along with waste brine disposal strategies. Baker Hughes is leading the engineering for brine extraction and transportation, a critical component for ensuring operational feasibility and environmental compliance.
Timeline and Next Milestones
Anson is targeting the completion of the DFS by January 2027, setting a clear timeline for the next phase of project development. This timing aligns with previous announcements that have outlined a pathway towards a 10,000 tonne per annum lithium carbonate operation. The DFS outcomes will be pivotal in refining capital expenditure and operating cost assumptions, which remain undisclosed at this stage but are expected to underpin future investment decisions.
While the announcement does not provide specific cost figures or production schedules beyond the DFS completion target, it signals steady progress in a competitive lithium market. The involvement of globally recognised engineering firms like Sedgman and Baker Hughes lends credibility to the technical robustness of the study and the project's potential to contribute meaningfully to lithium supply chains.
Bottom Line?
Anson’s January 2027 DFS deadline will be a key milestone to watch for clarity on costs and production plans at Green River.
Questions in the middle?
- How will the DFS outcomes influence Anson’s financing strategy for Green River?
- What are the environmental management plans for waste brine disposal in the final DFS?
- Could the integration of technology providers lead to cost efficiencies beyond current estimates?
