Announcement PDF 8 July 2024 HIGH-GRADE ROCK CHIP ASSAYS EXTEND PROSPECTIVE LITHIUM HORIZON AT RED MOUNTAIN PROJECT, USA Grades up to 4,150ppm Li identified along 1.4km trend north of recent discovery Key Highlights • 81 rock-chip samples reveal the presence of highgrade lithium claystone mineralisation in outcropping and sub-cropping claystones at Red Mountain. • North-south trend of high-grade samples extends the claystone mineralisation 1.4km north of hole RMRC002, expanding the prospective horizon at Red Mountain • Exceptional grades of up to 4,150ppm lithium reported. • 20 samples return grades over 1,000ppm lithium indicating high-grade clays across the Project. • Assay results for the remaining eight drill holes expected in two batches by the end of July. Astute Metals NL (ASX: ASE) (“ASE”, “Astute” or “the Company”) is pleased to advise that rock chip assay results from its 100%-owned Red Mountain Lithium Project in Nevada, USA have returned high-grade mineralisation of up to 4,150ppm Lithium, further enhancing the project’s exploration and discovery potential. Notable results returned up to 1.4km north of the recently reported discovery include: • 4,150ppm Li, brown-green claystone sampled 490m north of RMRC002 • 2,900ppm Li, brown claystone sampled 990m north of RMRC002 • 2,550ppm Li, brown claystone sampled 1.40km north of RMRC002 A total of 81 samples were collected and assayed, adding to Astute’s understanding of the prospective horizons at Red Mountain and complementing the initial drill results from its maiden drilling campaign, for which assays for eight holes remain pending. The rock chip assays are shown, along with previous results including the recently announced high-grade lithium discovery, in Figure 1. These results suggest that the targeted high-grade lithium horizon persists further north than previously interpreted, with a number of high-grade samples located along an approximate north-south trend stretching 1.4km north of the northernmost drill hole, RMRC0021. The extended zone will be tested by future drilling at the project. Astute Chairman, Tony Leibowitz, said: “Our exploration team continues to deliver exciting results, with these latest rock chip results returning exceptional lithium grades and further expanding the potential scale of the Red Mountain Project. The latest results come from an area up to 1.4km north of the discovery we announced recently on 18 June and provide further evidence of the scale and potential of this project. “We are eagerly awaiting the assays from eight drill holes along the initial 4.6km of strike tested by our recent drilling, with these new rock chip results further extending the prospective horizon to over 6km – adding a significant new area for drill testing later this year. “The latest results suggest that Red Mountain could be a very large and significant lithium discovery, and we are looking forward to systematically unlocking its full potential.” Suite 6, Level 5, 189 Kent St, Sydney NSW 2000 | GPO Box 2733, Sydney NSW 2001 +61 (0) 2 8046 2799 | admin@astutemetals.com www.astutemetals.com Figure 1.

The Project area has broad mapped tertiary lacustrine (lake) sedimentary rocks known locally as the Horse Camp Formation2. Elsewhere in the state of Nevada, equivalent rocks host large lithium deposits (see Figure 3) such as Lithium Americas’ (NYSE: LAC) 16.1Mt LCE Thacker Pass Project3, American Battery Technology Corporation’s (OTCMKTS: ABML) 15.8Mt LCE Tonopah Flats deposit4 and American Lithium (TSX.V: LI) 9.79Mt LCE TLC Lithium Project5. After staking was completed, Astute completed an 819-point soil sampling campaign that revealed strong lithium anomalism in soils, with grades of up to 1,110ppm lithium and a coherent 50ppm+ lithium anomaly that extends over a strike length of 8km and is up to 2.8km wide2 (Figure 1). After completing the soil sampling campaign, the Company embarked on a rock-chip campaign at Red Mountain designed to test for lithium at strategic locations and across a range of outcropping and shallowly sub-cropping rock types (see Figure 2).. The results of this initialrock chip sampling revealed the presence of strongly mineralised claystone, with 10 claystones grading on average 1,102ppm lithium, ranging from 132-2,190ppm lithium2 In May through June 2024 a maiden Reverse Circulation (RC) drilling campaign was completed at the Project, with initial results indicating the potential discovery of a significant lithium deposit 1. The assay results included the following high-grade drill intersections: • • • RMRC001: RMRC002: RMRC003: 59.4m @ 1,300ppm Li / 0.69% Lithium Carbonate Equivalent 6 (LCE) from 73.2m 15.2m @ 810ppm Li / 0.43% LCE from 15.2m 6.1m @ 1,050ppm Li / 0.56% LCE from surface, and 12.2m @ 1,060ppm Li / 0.56% LCE from 18.3m Other attractive Project characteristics include outcropping claystone host-rocks and close proximity to infrastructure, including the Project being immediately adjacent to the Grand Army of the Republic Highway (Route 6), which links the regional cities of Ely with Tonopah. Next Steps The Company is awaiting outstanding assay results for the remaining eight drill holes completed as part of the maiden drill campaign at Red Mountain, which are expected to be returned in two batches during the month of July. Once received, a full interpretation of both drilling and surface sampling results will be conducted ahead of establishing detailed future plans, including follow-up drilling, for the Project.

These examples should not be taken as limiting the broad meaning of sampling. Rock chip samples were taken from outcropping or shallowly subcropping rocks using a geopick. Include reference to measures taken to ensuresample representivity and the appropriate calibration of any measurement tools or systems used. Claystone hosted lithium deposits are thought to form as a result of the weathering of lithium-bearing volcanic glass within tertiary-aged tuffaceous lacustrine sediments of the mapped Ts3 unit. Inputs of lithium from geothermal sources have also been proposed. Aspects of the determination of mineralisation thatare Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, suchas where there is coarse gold that has inherentsampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.

Verification of sampling and assaying Samples analysed by method ME-MS41 which is an ICP-MS method employing an aqua-regia digest. Aqua-regia is not considered a ‘total’ digest for many elements however is considered fit for purpose for lithium and has been used extensively by other parties exploring for lithium claystone deposits in the USA. Assay quality was monitored using pulp blanks, as well as certified reference materials (CRMs) at a range of lithium grades. Pulp blank results indicated no material contamination of samples from sample preparation or during the analytical process. CRM results were within 3 standard deviations of certified values. No material systematic bias nor other accuracy related issues were identified. The verification of significant intersections by either independent or alternative company personnel. Sample intervals to be assigned a unique sample identification number prior to sample despatch The use of twinned holes. Lithium-mineralised claystone Certified Reference Materials (standards)and pulp blanks were inserted into the sample stream at regular intervals (at least 1:25 ratio) to monitor lab accuracy and potential contamination during analytical processes Documentation of primary data, data entryprocedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. Location of data points Accuracy and quality of surveys used to locatedrill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.

Claims located on Federal (BLM) Land Drilling conducted on claims certified by the Bureau of Land Management (BLM) No known previous lithium exploration conducted at Red Mountain Exploration conducted elsewhere in Nevada by other explorers referenced in announcement body text The principal target deposit style is claystone hosted lithium mineralisation. Claystone hosted lithium deposits are thought to form as a result of the weathering of lithium-bearing volcanic glass within tertiary-aged tuffaceous lacustrine sediments of the mapped Ts3 unit. Lacustrine environments formed as a result of extensional tectonic regime that produced ‘basin and range’ topography observed across the stateof Nevada. Inputs of lithium from geothermal sources have also been proposed. Drill hole Information A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: ◦ easting and northing of the drill hole collar ◦ elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar ◦ dip and azimuth of the hole ◦ down hole length and interception depth ◦ hole length. Not applicable. 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. Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Not applicable Drill Intersections are quoted in both lithium ppm and as wt% Lithium Carbonate Equivalent (LCE). LCE is calculated as LCE = Li (ppm) x 5.323 / 10,000, as per industry conventions. 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 shownin detail. The assumptions used for any reporting of metal equivalent values should be clearly stated.

Not applicable. If the geometry of the mineralisation 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 notknown’). Diagrams Appropriate maps and sections (with scales) andtabulations 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. Included in ASX announcement 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 Exploration Results.
