Anson Targets 9,800 Feet Depth to Boost Lithium Resources in Utah

Anson Resources has initiated a re-entry drilling program at its Mt Fuel-Skyline Geyser well in Utah, aiming to convert exploration targets into JORC-compliant lithium resources by sampling deep lithium-rich brines.

  • Re-entry drilling commenced at Mt Fuel-Skyline Geyser 1-25 well
  • Target depth extended to 9,800 feet for brine sampling
  • Program aims to upgrade Exploration Target to Indicated and Inferred JORC Resources
  • Historical data and nearby Bosydaba #1 well confirm lithium-rich brines presence
  • Drill stem tests to assess reservoir porosity and flow rates for future production

Context and Objectives

Anson Resources Ltd (ASX – ASN) has embarked on a significant re-entry drilling campaign at the Mt Fuel-Skyline Geyser 1-25 well, part of its Green River Lithium Project in southeastern Utah. The initiative aims to deepen the existing well to approximately 9,800 feet to collect brine samples from the Paradox Formation and the Leadville Mississippian Units. This program is designed to convert a large Exploration Target into more definitive Indicated and Inferred Mineral Resources under the JORC Code, thereby enhancing the project's resource base.

Geological Significance and Historical Data

The Paradox Basin, where the project is located, is known for its complex geology featuring evaporite sequences and porous dolomite formations that can trap lithium-rich brines. While historical oil and gas drilling intersected supersaturated brines, lithium assays were not previously conducted. Recent drilling at the nearby Bosydaba #1 well, just 12 kilometers north, confirmed the presence of lithium-rich brines, bolstering confidence in the Mt Fuel-Skyline Geyser well’s potential. Assay comparisons of salts and minerals between the two wells suggest similar geochemical profiles, implying promising lithium content at Mt Fuel.

Technical Approach and Sampling Strategy

The re-entry program involves mobilizing a large drilling rig to deepen the well and sample multiple aquifers identified by geological modeling. Sampling will follow industry best practices, with brine collected in secure containers and analyzed using certified laboratories specializing in oilfield brines. Drill Stem Tests conducted historically and planned during this program will provide critical data on reservoir porosity and permeability, essential for estimating flow rates and supporting future lithium extraction operations.

Strategic Implications for Anson Resources

This drilling campaign represents a pivotal step for Anson Resources in advancing its Green River Lithium Project towards commercial viability. By upgrading resource classifications and confirming lithium concentrations, the company aims to strengthen its position in the growing lithium market driven by demand for electric vehicles and energy storage technologies. The project’s geological setting, combined with positive assay results from nearby wells, positions Anson to potentially deliver a significant new lithium resource in the United States.

Looking Ahead

While the re-entry program is underway, the market will be watching closely for assay results and resource updates that will clarify the economic potential of the Mt Fuel-Skyline Geyser well. The company’s ability to demonstrate sustainable flow rates and reservoir pressure will be critical to advancing development plans. Anson’s methodical approach to leveraging historical data alongside new drilling underscores its commitment to unlocking value in this emerging lithium province.

Bottom Line?

Anson’s re-entry drilling at Mt Fuel-Skyline could be a game-changer, but upcoming assay results will be the true test of its lithium ambitions.

Questions in the middle?

  • Will lithium assays from the Mt Fuel-Skyline Geyser well confirm resource upgrade expectations?
  • How will drill stem test results influence projections for sustainable lithium brine extraction?
  • What timeline can investors anticipate for resource certification and potential project development?
