- Anson Resources expands Green River lithium footprint by 10%
- New claims include promising oil wells for lithium-rich brine
- High permeability supports long-term lithium production
Anson Resources (ASX:ASN) has taken a significant step in advancing its lithium ambitions by expanding its Green River Lithium Project in Utah, USA. The company has secured an additional 100 strategic claims, increasing the project's total footprint by nearly 10%, now spanning 88.61 square kilometres.
This expansion aligns with Anson’s broader exploration strategy, which involves reviewing historical oil and gas wells for their potential to contain lithium-bearing brines. The newly pegged claims include two such wells, both of which have shown evidence of brine flowing near the surface. These wells, particularly the Grand Fault Unit 14-24, are considered prime candidates for re-entry and future resource upgrades.
The Grand Fault Unit 14-24 extends deep into the Mississippian Unit and is located adjacent to a naturally flowing geyser, suggesting high porosity. Anson notes that drill stem tests conducted in this well, as well as in the Green River Unit 1 and other historical wells across the area, have revealed high permeability in the Mississippian strata.
This high permeability is a promising sign for Anson’s future development plans, as it could support consistent brine flow rates necessary for lithium extraction. The consistency in pressure across the formation is also seen as a favourable factor that could enhance the long-term viability of lithium production from this region.
Historically, the Green River region had limited lithium data, but recent drilling efforts by Anson have uncovered supersaturated brines, particularly at the Bosydaba #1 well, located in the northern section of the Paradox Basin. These findings mark a breakthrough in understanding the area's lithium potential.
The newly staked claims were filed through Anson’s wholly-owned subsidiary, Blackstone Minerals, and now form a contiguous landholding with the company’s previously approved Area of Influence by the Utah state government. Approximately 28% of these new claims are expected to be incorporated into Anson’s next JORC mineral resource estimate.
While Anson Resources is not currently classified within the ASX 200 companies, its aggressive expansion strategy and promising lithium exploration data continue to make it a company of growing interest in the resource development space.
This move underlines the company’s commitment to developing a significant lithium asset in the United States and supports its broader goals of contributing to the global clean energy transition.
