Anson Expands Green River Lithium Project by 10%, Adds Key Re-entry Targets
Anson Resources has expanded its Green River Lithium Project in Utah by acquiring 100 new placer claims, increasing the landholding by 10% and identifying promising re-entry targets in historical wells to potentially enhance lithium resource estimates.
- 100 new placer claims added, expanding project area by 8.23 km² to 88.61 km²
- 28% of new claims fall within Area of Influence for upcoming JORC resource updates
- Two historical oil wells with near-surface brine flows identified as re-entry targets
- Geological features indicate high porosity and permeability favorable for lithium extraction
- Plans underway for further exploration and resource estimation upgrades
Strategic Expansion of Green River Lithium Project
Anson Resources Limited (ASX – ASN) has announced a significant expansion of its Green River Lithium Project in southeastern Utah, USA, through the acquisition of 100 additional placer claims. This move increases the project’s land package by approximately 10%, adding 8.23 square kilometers to bring the total footprint to 88.61 square kilometers. Notably, about 28% of these new claims lie within the project's Area of Influence (AOI) and will be incorporated into forthcoming JORC Mineral Resource estimate upgrades.
Unlocking Potential from Historical Oil Wells
The newly acquired claims are contiguous with a recently granted State government OBA lease, forming a consolidated land block. Within this area lie two historical oil wells; the Grand Fault Unit 14-24 and Green River Unit 1 wells; that recorded brine flowing near the surface. These wells, drilled in the 1960s, were never assayed for lithium but are now considered prime re-entry targets. The Grand Fault well, in particular, extends deep into the Mississippian Unit and is adjacent to a continuously flowing geyser, an indicator of high porosity and permeability in the subsurface formations.
Geological Advantages Support Lithium Extraction
Geological structures such as the Ten Mile Graben and Little Grand Wash Fault traverse the project area, contributing to favorable reservoir characteristics. Drill Stem Tests (DST) from these historical wells suggest the Mississippian strata exhibit high permeability, which is critical for sustaining brine flow rates necessary for lithium extraction. The presence of a continuously flowing geyser near the Grand Fault well further underscores the high-pressure environment, which could help maintain reservoir pressure and enhance brine recovery over the project’s lifespan.
Next Steps and Exploration Outlook
Anson Resources plans to incorporate the new claims into its next JORC Mineral Resource update, reflecting the expanded landholding and potential resource additions from the re-entry targets. Future exploration will focus on sampling brines from these wells and surrounding areas to confirm lithium concentrations and assess resource continuity. The company’s strategic approach aims to leverage existing geological data and historical well infrastructure to accelerate resource development and position the Green River Project as a significant lithium producer in the US market.
Bottom Line?
Anson’s expanded footprint and re-entry targets set the stage for a potentially larger lithium resource, but assay results and drilling outcomes will be critical to validate this promise.
Questions in the middle?
- What lithium concentrations will assays from the re-entry wells reveal?
- How soon can Anson commence re-entry drilling and sampling operations?
- What regulatory or environmental hurdles might impact project expansion?
