Drilling Fluids from Mt Fuel-Skyline Geyser 1-25 Well Test Positive For Significant Lithium Grades

ASX: ASN Announcement

Highlights:

• Grades up to 148ppm Li were recorded from the Mt Fuel Skyline Geyser well drilling program,

• The samples of heavy drilling fluid that were assayed were collected from the Mississippian Units, Leadville Formation between 9,189ft and 9,239ft,

• Mississippian Mt Fuel Skyline Geyser estimated to be 650ft to 660ft thick according to 3D model.

• Assay results and other data to support an increase in the JORC resource estimate have been sent to third party company for consideration for inclusion in revised resource estimate.

Anson Resources Limited (ASX: ASN ) (“ Anson Resources ” or the “ Company ”) through its 100% owned subsidiary Blackstone Minerals NV LLC is pleased to announce that it has received a value of 148ppm lithium assayed by an accredited laboratory from the drilling fluid that circulated the Mississippian horizon at 9,189ft in the re-entry drilling program of the Mt Fuel-Skyline Geyser 1-25 well. Drilling through the top of the Mississippian Units detected that an amount of chloride brine had entered the heavy drilling fluids at its Green River Lithium Project (Project) in south-eastern Utah, USA.

The aim of the program was to confirm lithium rich brines are located in the target horizons, which will be used to increase the overall Project JORC Mineral Resource in addition to the Resource announced at the Bosydaba #1 well 12km to the north, see ASX Announcement 22 October, 2025.

The drilling program was not able to continue beyond the depth of 9,239ft due to technical difficulties. As a result drilling completely through the Mississippian Unit was not achieved. This also prevented the collection of brine samples from the Paradox Formation, Clastic 31.

However, the drilling fluids that were able to be recovered from the Mississippian Unit was sufficient to allow for assays to be conducted which determined a lithium grade of 148ppm, higher than that recorded at the Boysdaba #1 well and in line with the Company’s expectation that the grade would be higher closer to the the Graben, the parallel fault lines, just south of the Mt Fuel Skyline Geyser 1-25 well. Some time was needed to allow the muds to separate from the drilling fluids to enable an accurate assay result of the contained lithium, which delayed the analysis of the sample.

Similar test work was conducted on drilling fluids while drilling the Boysdaba #1 Well. The analysis of this fluid proved to be similar to that of raw brine later collected, see Table 1. It is considered that a similar result would be achieved if a brine sample could have been collected from the drilling program at the Mt Fuel Skyline Geyser 1-25 well.

Table 1: Assay results from the drilling fluids & supersaturated brines of Bosydaba#1 & Mt Fuel Skyline wells.

Table 1 shows a comparison of results for both the drilling fluid assays from the Bosydaba and Mt FuelSkyline wells. The results obtained from both wells explains why the drilling fluids contain higher cation values compared to that of the “clean flowing” salts assayed at the Bosydab#1 well and the historical wells.

After consultation with an independent company that provides JORC resource estimates, it has been determined that a grade similar to that at Bosydaba can be used for a JORC resource upgrade across the entire project area, including the Mt Fuel-Skyline Geyser 1-25 well area of influence, which should result in a significant increase in the JORC resource estimate, see Figure 2.

Figure 2: Plan showing the location of the Mt Fuel-Skyline Geyser and the area of influence around it.

The higher assay results for magnesium, potassium and calcium as shown in Table 1 are attributed to the bentonite that is used to form the heavy drilling fluids to control gas and oil surges while conducting the drilling program. Bentonite consists of silica (SiO2), alumina (Al2O3), iron (Fe2O3), magnesium (MgO), calcium (CaO), sodium (NaO2) and potassium (KO2). During the drilling of the Bosydaba well drilling fluids were also sampled through the top of the Mississippian Units.

Data of the historical drilling results from the Project area has been imported into 3D models by Anson, see ASX Announcements 19 July 2023 and 19 June 2025 . This estimnated that the interpreted thickness nof the Mississippian Units at Mt Fuel-Skyline Geyser 1-25 well to be 650 to 660ft, see Figure 3. This estimate has also been provided to the third party company conducting the JORC resource estimate review for consideration for inclusion in the JORC resource upgrade.

All data received from the Mt Fuel-Skyline well drilling, including fluid assays results and 3D modelling thickness estimates as well as details of the Bureau of Land Management (BLM) additional claims area that were added to the Green River Lithium Project area, see ASX Announcement7 July 2025, have been sent to an independent company for consideration in the revised JORC resource estimate review which has already commenced.

Executive Chairman and CEO, Mr Bruce Richardson commented, “Anson has been working hard on increasing the JORC Resource estimate at the Green River Lithium Project in several aspects, and we are beginning to see the results of those efforts. This was not an easy drilling program, not only due to the depth but also the geology challenges created by the garben and pressure in this area. Anson encountered issues with the originally planned re-entry program of the Mt Fuel-Skyline Geyser 1-25 well but quickly pivoted to drilling a new side-tracked well, and successfully collected a sample of brine from 9,239 ft. This demonstrates the exceptional skills and experience of the Anson geological, drilling and management team, in quickly obtaining approval or the revisied drilling program and carrying out that program.

	Criteria	JORC Code Explanation	Commentary
	Drill Hole Information	• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for allMaterial drill holes: -easting and northing of the drill hole collar -elevation or RL (Reduced Level – elevation above sea level in meters) ofthe drill hole collar -dip and azimuth of the hole -down hole length and interception depth -hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	• The grid system used is UTM Zone 12 (NAD83). • Drillhole collars, (Dip -900, Azim 00) • Bosydaba#1: 4,303,268.5N, 576,941.4E, EL: 4,125.7’ • Mt Fuel-Skyline Geyser 1-25: 4,303,066.8, 577,018.7E, EL: 4,120’
	Data Aggregation Methods	• In reporting Exploration Results, weighting averaging techniques, maximumand/or minimum grade • Brine samples taken in holes were averaged (arithmetic average) without 14 Criteria JORC Code explanation Commentary truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated.	• No weighting has been carried out. • No brine samples have been collected to assay for lithium in the historica exploration programs. • Anson has sampled for lithium at its Bosydaba#1 well.
	Relationship Between Mineralization Widths and Intercept Lengths	• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’).	• The sediments hosting the brine aquifer are interpreted to be essentially perpendicular to the vertical oil wells. Therefore, all reported thicknesses are believed to be accurate. • Brines are collected and sampled over the entire perforated width of the zone • The Mississippian Units are assumed to be porous and permeable over its entire vertical width based on drilling records.
	Diagrams	• Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	• The appropriate diagrams are shown in the text showing the location of the wells.
	Balanced Reporting	• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of ExplorationResults.	• The historical wells intersected muds and brines but only one sample wass assayed while drilling the oil exploration well • The wells have been Plugged and Abandoned and tested for oil shows and was not assayed for lithium brines
