Anson Expands Green River Lithium Project by 5.4% with FFSL Mineral Rights Win
Anson Resources has secured 1,175 acres of mineral rights from Utah’s FFSL, boosting its Green River Lithium Project and setting the stage for a resource upgrade and feasibility study.
- Acquisition adds 1,175 acres of lithium-rich brine tenure
- Project area grows by 5.4%, linking east and west claims
- New leases fall within Indicated and Inferred JORC Resources
- Exploration target of up to 71 million tonnes brine at 130 ppm lithium
- JORC resource update and feasibility study planned for Q3 2026
Strategic Land Win Enhances Project Contiguity and Scale
Anson Resources (ASX:ASN) has successfully outbid competitors to acquire mineral rights covering 1,175 acres of lithium-rich brine territory managed by Utah’s Division of Forestry, Fire and State Lands (FFSL). This addition increases the footprint of its Green River Lithium Project by 5.4%, effectively joining previously separate east and west claim blocks into a contiguous land package. The newly secured tenure is poised to be included in the company’s upcoming JORC Resource update scheduled for Q3 2026.
Leases Align with Existing Resource Classifications
The FFSL leases 1 to 4 sit within the project’s current Indicated JORC Resource area, while leases 5 to 8 fall within the Inferred Resource zone of the newly interpreted area of interest. This alignment means the new acreage is not just incremental land but holds material mineral potential already supported by third-party resource modelling. Anson’s approach to incorporate these leases into the resource base without further drilling aligns with its strategy to enhance resource estimates efficiently and cost-effectively.
Lithium-Rich Brines Offer Processing Advantages
Geochemical assays from the adjacent Bosydaba #1 and Mt Fuel-Skyline Geyser wells confirm the presence of lithium-rich brines with concentrations around 130 ppm lithium. Notably, these brines exhibit significantly lower impurities such as iron and magnesium compared to other regional deposits, implying potentially lower processing costs. This cleaner brine chemistry could be a competitive advantage as Anson advances towards commercial production.
Exploration Target Highlights Upside Potential
Anson has outlined an exploration target for the FFSL ground ranging from 59 to 71 million tonnes of brine grading between 100 and 130 ppm lithium. This target is conceptual and based on geological data including formation thickness and brine assays from recent drilling. While not yet classified as a Mineral Resource, this target suggests meaningful upside to the project’s lithium inventory once formally incorporated into the JORC framework.
Next Steps Focused on Resource Upgrade and Feasibility
With the FFSL leases secured and pending approval of an Overlying Bond Application (OBA), Anson plans to appoint an independent consultant to update the Green River JORC Resource. This update will feed directly into the company’s Definitive Feasibility Study (DFS), a critical milestone for securing project funding in 2027. The DFS is already underway, supported by recent advances in lithium processing validation and strategic partnerships, positioning Anson to accelerate development of its Utah lithium assets.
Bottom Line?
Anson’s FFSL mineral rights win strategically expands and consolidates its Green River Lithium Project, setting up a resource upgrade and feasibility study that could unlock significant value without additional drilling.
Questions in the middle?
- How will the upcoming JORC Resource update impact Anson’s project valuation and funding options?
- What are the timelines and risks associated with regulatory approvals for the OBA and FFSL leases?
- How might the cleaner brine chemistry influence Anson’s processing costs relative to peers?
