Anson Resources Limited (ASX: ASN, ASNOC, ASNOD) (Anson or the Company) is pleased to announce that it has completed a successful Direct Lithium Extraction (DLE) test work program on Mississippian brine samples from the Long Canyon Unit 2 and Cane Creek 32-1 wells at its Paradox Lithium Project (the Project) in Utah, USA.
Highlights:
- Successful Direct Lithium Extraction (DLE) test work program completed on Mississippian brines from the Long Canyon Unit 2 and Cane Creek 32-1 wells
- Program utilised the DLE process of Anson’s DLE partner, Sunresin, and involved adsorption and desorption tests which produced positive results from both feed brines
- Test work confirmed the ability of Sunresin’s resin to selectively adsorb lithium over other elements – magnesium, potassium and sodium – in the supersaturated brines
- Program also delivered similar results to previous test work on Clastic Zone 31 brines at the Paradox Project
- Based on the positive results, further test work to define the optimal extraction methodology for the Mississippian brines has commenced.
The test work program utilised the DLE process of Anson’s DLE partner, Sunresin. It involved adsorption and desorption tests, which produced positive results from both feed brines – from the Long Canyon Unit 2 well and the Cane Creek 32-1 well.
The test work confirmed the ability of Sunresin’s resin to selectively adsorb lithium over other elements – such as magnesium, potassium, and sodium – in the supersaturated brine, and successfully confirmed its suitability and effectiveness on the Mississippian brines at the Project.
The program was carried out by an independent laboratory in Salt Lake City, Utah, see Figure 1, and was completed using a small-scale DLE pilot plant successfully used for previous test work by Anson on brine from the Clastic 31 zone within the Project area. Importantly, the latest test work on the Mississippian brine samples has produced similar results to the previous program on the Clastic 31 brines, see ASX Announcement 13 August, 2021.
Based on the successful outcomes of the test work on the Mississippian brines at the Project, Anson has commenced a next phase of test work, to define the optimal extraction methodology for the Mississippian brines.

Test Work Methodology and Commentary
The benchtop test work program examined the ability of the resin used in the DLE process, provided by Sunresin, to selectively adsorb lithium over other elements in the supersaturated brine, including magnesium, potassium and sodium.
This was carried out by assaying numerous samples of the discharged, spent brine for the various elements present in the brine on completion of the adsorption process. All adsorption tests consistently showed the element concentrations remained near the feed brine concentrations throughout each cycle.
Following the adsorption tests, desorption tests were conducted on each lithium “loaded” resin column. Prior to the desorption cycle, the resin columns were allowed to drain of all the remaining feed brine.
Once the columns had drained, purified water (DI water) was used as the elution fluid to flush the resin; elution is the process of extracting a substance that is adsorbed to another by washing it with a solvent. The collected samples were analysed for lithium concentration to establish the desorption characteristics for the loaded resin.
The desorption process using DI water demonstrated the ability to readily release the lithium from the loaded resin for the Mississippian feed brines at both Long Canyon Unit 2 and Cane Creek 32-
1. Results of the desorption tests were aligned with previous desorption tests conducted on Clastic Zone 31 brine samples from the Skyline and Long Canyon wells. The concentration of lithium in the eluate significantly increased, see ASX Announcement 13 August 2021.

Anson Resources: Developing a Near-Term Clean Energy Project in Utah
Anson Resources (ASX:ASN) focuses on the resources necessary to meet the energy demands of the future. The company’s flagship project, the Paradox Lithium Project, has the potential to become a world-class lithium producer and is located near Tesla’s massively productive gigafactory in the United States. Additional projects target nickel, copper, and uranium.
The company's flagship Paradox Project is located in Utah, a mining-friendly and politically stable jurisdiction. The asset holds significant lithium brine deposits, and the company has identified an extraction method that has delivered an extraction rate of 91.5 percent. This technique calls for passing the lithium through the resin, which captures the resin, and can then be separated from the resin with water. From that state, it can be processed into lithium carbonate. The company is currently undertaking a major JORC resource expansion drilling program, the results of which will feed into a Detailed Feasibility Study being carried out by global engineering firm, Worley.

- 35,000m Step-up drill campaign well underway with the plan to bring forward ounces and increase the mine plan
The program focused on converting Inferred stopes at Pollard, United North and Youanmi Main to higher confidence Indicated classification and providing material for metallurgical testing for the upcoming Definitive Feasibility Study (DFS) – on track for H2 CY25.
This final consignment of diamond assay results are the fourth batch of assays results returned from the drill program and have been entirely drilled from the Pollard, Youanmi and United North areas (Figure 1).
Rox Resources’ Chief Executive Officer, Phillip Wilding, commented:
“It’s pleasing to round out the 11,000m RD and DD drilling program with another batch of excellent intercepts.
“More importantly, the program has significantly improved our knowledge of the high grade and underexplored Youanmi ore system, and shown that mineralisation remains open at depth.
“Next steps are to convert Inferred areas of the Resource to the higher confidence Indicated classification, and finalise key intercepts of sample material for metallurgical test work to feed into the Youanmi DFS.
“We are excited to have commenced the 35,000m Step-up program to potentially bring forward ounces in the mine plan and significantly increase the size of the Pollard ore zone.”
Youanmi Major Growth Drill program
Resource drilling has focused on converting selected Inferred stopes in the current Mineral Resource of 16.2Mt at 4.4g/t Au for 2.3Moz (Indicated: 10.7Mt at 4.5g/t Au for 1.6 Moz : Inferred 5.5Mt at 4.2g/t Au for 0.7 Moz) 1 to higher confidence Indicated classification at Pollard, United North and Youanmi Main as shown in plan on Figure 1. The drilling has also provided both sample material for metallurgical testing and valuable geological data for the pending Definitive Feasibility Study (“DFS”) planned for second half of 2025.

Drilling Commenced at Viani in Fiji
HIGHLIGHTS
- The Phase 1, three-hole diamond drilling program has commenced at the Viani Project, Fiji and will test for extensions to the quartz vein gold mineralisation at depth.
- Phase 1 is expected to be completed in early 2025, with plans for additional drilling under the same program dependent on the initial results
- The Viani Project (SPL1513) covers an area of approximately 200km2 and is largely underexplored.
- At the Dakuniba prospect within Viani, low sulphidation epithermal high-grade gold mineralisation has been mapped over >3km strike length.
- Diamond drilling completed by Japan International Cooperation Agency (JICA) in 1995 to 1997 intersected high-grade gold in low sulphidation epithermal quartz veins, including 0.6m @ 27.6 g/t Au.
Alice Queen’s Managing Director, Andrew Buxton said,
With drilling underway, Alice Queen is positioned to test the epithermal gold-style mineralisation identified in historic drilling at the Viani Project. Weather permitting, we anticipate completing the Phase 1, three-hole diamond drilling program in early 2025. Following this, our exploration team will mobilise the drill rig to the Sabeto Project in Fiji to maintain the momentum of this campaign. To deliver timely results to shareholders, we intend to accelerate the analysis of the drill core at ALS Brisbane.”

Details
Geology
The geology of the Viani Project (SPL 1513) comprises olivine basalts and volcaniclastics of the Natewa Volcanic Group which are intruded by andesite sills and dykes. In the 1940s, gold mineralisation was found by local prospectors near the village of Dakuniba. At Dakuniba, low sulphidation style epithermal gold occurs in quartz veins, and silicified rocks along a 3km long NE trending zone.
In 1995-1997, Japan International Cooperation Agency (JICA) drilled six diamond holes at Dakuniba and intersected high-grade gold in chalcedonic, crustiform, colloform banded quartz veins at depths of 50m to 100m below surface (i.e. MJVFV-5 intersected 2.2m @ 11.3 g/t Au, incl 0.6m @ 27.6 g/t Au at 121m downhole). This high-grade gold mineralisation is open in all directions.
Proposed Drill program
The initial Phase 1 drill program at Viani (see Table 1) will comprise three diamond drillholes designed to test continuity to the epithermal gold mineralisation previously intersected in JICA drillhole MJVFV- 5 (2.2m @ 11.3 g/t Au) (see Figure 2). The drilling will test for extensions to the gold mineralisation at depth and along strike.
