Rincon Lithium Project Faces Key Tests Despite 96% Recovery and Power Line Progress
Argosy Minerals reports strong progress on its 12,000 tonnes per annum Rincon Lithium Project in Argentina, achieving 96% lithium recovery in test work and advancing critical energy infrastructure with a 40MW power supply line.
- 96% lithium recovery confirmed in process test work
- High purity lithium chloride concentrate successfully produced
- Pilot plant operations underway to validate process flowsheet
- 40MW medium voltage power line contracted to support project
- Staged product development strategy focusing initially on lithium chloride
Project Progress and Test Work Success
Argosy Minerals Limited (ASX: AGY) has provided a detailed update on its flagship Rincon Lithium Project located in Salta Province, Argentina. The company has reported encouraging results from its ongoing engineering and feasibility studies, highlighting a 96% lithium recovery rate from recent process test work. This high recovery rate validates the robustness of the process flowsheet designed to produce a high purity lithium chloride concentrate, a key intermediate product in the lithium supply chain.
The test work has progressed to continuous pilot plant operations in Argentina, aiming to demonstrate consistent process performance and refine economic parameters. These pilot operations are critical to finalising the feasibility report and underpinning a future final investment decision (FID).
Staged Development Strategy
Argosy is pursuing a two-stage product development pathway. The initial stage (Stage 1a) focuses on producing solid lithium chloride on-site, which offers several commercial advantages including lower upfront capital expenditure, faster market entry, and alignment with growing demand for lithium iron phosphate (LFP) batteries. The subsequent stage (Stage 1b) will evaluate converting this lithium chloride into battery quality lithium carbonate or hydroxide, or alternatively, assess the viability of directly exporting the lithium chloride product.
This staged approach is designed to reduce operational complexity and technical risk while maintaining flexibility to respond to market conditions and strategic partnerships.
Energy Infrastructure Development
Complementing the process advancements, Argosy has made significant strides in securing energy infrastructure critical to the project’s long-term viability. The company has engaged Lycopodium as Owner’s Electrical Engineer to advance the construction of a 40MW medium voltage line. This line will connect the Rincon site to the national grid via an 8.6-kilometre transmission line linked to the nearby Altiplano Solar Facility, ensuring a stable and sustainable power supply.
The involvement of Electricity Distribution Company S.A. (EDESA) in the design and feasibility study phase has confirmed the technical viability of this power solution, which is expected to underpin the project’s operational needs.
Outlook and Market Positioning
Argosy’s Managing Director Jerko Zuvela emphasised the importance of these milestones, noting the positive momentum generated by the successful test work and energy infrastructure progress. The company remains focused on completing the feasibility report and targeting a final investment decision, which will further de-risk the project and position Rincon as a competitive lithium supplier within the globally significant Lithium Triangle.
With lithium demand forecast to grow strongly, particularly for energy storage and electric vehicle applications, Argosy’s strategy to produce a versatile lithium chloride intermediate product could provide strategic advantages in a rapidly evolving market.
Bottom Line?
Argosy’s Rincon Project is steadily advancing towards commercialisation, with pilot plant validation and energy infrastructure development setting the stage for a pivotal final investment decision.
Questions in the middle?
- Will Argosy proceed with downstream conversion to battery quality lithium carbonate or hydroxide, or focus on lithium chloride exports?
- How will the company manage capital expenditure and financing as it moves towards final investment decision?
- What are the timelines and risks associated with completing the 40MW power line and pilot plant operations?
