Detailed drill sample petrographic analysis is ongoing to vector towards higher-grade zones. - Surface and Downhole Results: Surface rock samples previously returned up to 17.9 g/t Au and 0.7% Sb. Drilling highlights broad mineralisation across an orogenic system. - Strategic Location: Amoco lies ~19 km south-east of Larvotto Resources’ (ASX:LRV) Hillgrove Antimony-Gold Project and ~14 km east of Koonenberry Gold’s (ASX:KNB) Enmore Gold Project, within the fertile New England Fold Belt, NSW. - Ongoing Exploration: Permitting for extended drilling across the ~2 km gold-in-soil anomaly is progressing with NSW Resource Regulator. Follow-up work with further petrographic analysis and structural mapping to guide future exploration activities. Critical Resources Limited (‘Critical Resources’ or the ‘Company’, ASX:CRR) is pleased to provide an update on the Amoco Gold-Antimony Project (Amoco), following the successful completion of its maiden Reverse Circulation (RC) drilling program in the Armidale region of New South Wales, Australia. The Amoco Project is located ~19 km south-east of Larvotto Resources’ Hillgrove Antimony-Gold Project, within the highly prospective New England Fold Belt. The Amoco Project was identified through systematic geochemical surveys and mapping, with previous surface rock samples returning up to 17.9 g/t Au and 0.7% Sb. The region is renowned for its antimony-gold production history and recent exploration success, positioning Amoco as a compelling target for new orogenic gold-antimony discoveries. Critical Resources Managing Director, Tim Wither, commented: ‘The confirmation of a substantial orogenic system at Amoco validates our geological model and exploration approach. The presence of features consistent with Hillgrove-style mineralisation, together with strong pathfinder anomalism and extensive alteration, provides a solid foundation for continued work. We remain focused on systematically advancing our Halls Peak projects in the highly prospective New England Fold Belt, with the aim of unlocking significant value for our shareholders through targeted exploration.’ Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR DISCOVERY OF OROGENIC SYSTEM The Amoco Gold-Antimony Project, located in the Armidale region of New South Wales, sits approximately 19 km south-east of the Hillgrove Antimony-Gold Project and approximately 14 km east of the structural corridor hosting Koonenberry Gold’s Enmore Gold Project. This corridor is renowned for its rich history of gold and antimony production and recent exploration success, making it one of the most prospective areas within the New England Fold Belt. Amoco’s strategic position within this highly fertile geological setting underscores its potential for significant new discoveries. The region continues to attract strong exploration interest due to its proven mineral endowment and favourable structural controls. Critical Resources began exploration at Amoco with detailed geochemical surveys and mapping. A targeted soil sampling program over 3 x 2 kilometres identified promising drill zones, with assays up to 21.0 ppb gold (Au), 14.65 ppm antimony (Sb), and 351 ppm arsenic (As). These results, closely aligned with key geological structures, provided the confidence to advance to drilling, which has now confirmed the presence of an orogenic system. TECHNICAL AND EXPLORATION UPDATE Since commencing work at Amoco, Critical Resources has systematically advanced the project through geochemical surveys, mapping, and now drilling. The maiden RC drilling program has validated the Company’s exploration strategy and geological models, confirming the presence of a substantial, fault- controlled orogenic system with strong multi-element anomalism, including gold up to 0.38 g/t Au, silver up to 22.7 g/t Ag, antimony up to 133 ppm Sb, copper up to 0.27%, lead up to 0.46%, and zinc up to 0.85%. The drilling highlights include: • 1 m @ 0.38 g/t Au, 22.7 g/t Ag from 36 m (ARC-012) • 3 m @ 0.22 g/t Au, 6.4 g/t Ag, 0.32% Pb, 103 ppm Sb from 21 m, incl., 1 m @ 0.32 g/t Au, 10.1 g/t Ag, 0.46% Pb, 133 ppm Sb from 21 m, within 22 m of hydrothermal alteration from 21–42 m (ARC-005) • 1 m @ 0.21 g/t Au from 63 m (ARC-011) • 1 m @ 0.20 g/t Au, 22.2 g/t Ag, 0.17% Cu, 0.34% Pb, 61 ppm Sb, 0.85% Zn from 13 m (ARC-004) Key geological observations include: • Anomalous arsenic up to 7,020 ppm (0.7%) As with relatively low base metals (Pb up to 0.46%, Zn up to 0.85%, Cu up to 0.27%) combined with sulphide mineralogy and quartz textures is consistent with an orogenic gold mineralised system. • Drilling intersected structurally controlled, hydrothermally emplaced quartz–sulphide system, up to 22 metres wide downhole (ARC-005), with open epithermal textures observed. • Hosted in fault-brecciated fine-grained sedimentary rocks, intensely altered by heat and fluid flow— typical of orogenic systems capable of hosting high-grade mineralisation. These results confirm the presence of a substantial orogenic system with strong pathfinder anomalism, supporting the Company’s exploration model and providing a robust foundation for future work.

This analysis will leverage specialist expertise in Hillgrove-style mineral systems to refine understanding of mineralisation and guide future exploration. • Target Refinement: Structural mapping and detailed geochemical analysis will continue, aimed at identifying and prioritising potential feeder zones—areas most likely to host higher-grade mineralisation, as indicated by surface rock samples up to 17.9 g/t Au and 0.7% Sb. • Follow-Up Drilling: Planning is underway for the next round of drilling, focusing on the most promising structural corridors and surface anomalies identified to date. The goal is to expand known mineralisation and improve mineralisation understanding. Permitting for the secondary gold-in-soil anomaly is progressing with the NSW Resource Regulator. Once approved, the next phase of drilling will target deeper zones and potential feeder structures highlighted by ongoing technical work.

Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g., cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are 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, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. • Reverse circulation (RC) samples were collected by a cone splitter for one metre sample intervals. Reverse circulation drilling was used to obtain 1 m samples from a nominal 3 - 5 kg weight was supplied to ALS for sample preparation. • Field duplicates were collected. Certified duplicates and blanks were included in sample batch dispatched to ALS. • To ensure industry standards, RC drill samples were dispatched to ALS Minerals (Brisbane) and prepared and analysed by the following methods. • RC samples were analysed by ME-ICP61 for 34 elements and gold by Au-AA25 Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). 12 Reverse circulation drill holes were completed using a 5.5” RC hammer Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results is assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Sample recoveries and wet samples were monitored and recorded qualitatively in RC drill logs. Recoveries were generally 80-100%. High pressure air was used to maintain a dry sample and drill sampling equipment was cleaned regularly to minimise contamination. There is no apparent relationship between sample recovery and grade Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. All RC holes are geological logged every metre. The lithology, alteration, mineralisation and structural characteristics are logged directly into a digital format. Logging of RC chips is mostly qualitative, except for some semi- quantitative logging of sulphide content, quartz veining, alteration. Sub-sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. RC samples were split using a rig-mounted cone splitter on 1m intervals to obtain a sample for assay, of approximate weight 3 – 5kg. RC drilling is an established method designed to minimise drilling- induced contamination of samples, aimed to deliver a representative Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR Criteria JORC Code explanation Commentary • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. sample of the interval being drilled. Sample moisture was monitored, and water is blown out at each rod change prior to resuming drilling. Hole terminated if sample is wet. If the site location was deemed to have possible transported material, either the soil sample was not taken, or taken from a different site. The sample sizes are standard industry practice. Sample sizes collected under standard industry conditions and by standard methods, that are considered appropriate for the medium being sampled The laboratory techniques employed and the type and style of mineralisation which might be encountered at this project. Sample sizes are considered appropriate for the style of mineralisation sought. QA/QC procedures included the insertion of certified standards and blanks and field duplicates were submitted to the laboratory. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis include instrument make and model, reading times, calibration factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. • RC samples were analysed by ALS Brisbane by ME-ICP61 for 34 elements via four acid digest and ICP-AES, gold by Au-AA25, overlimit samples were analysed by Mn-OG62. • The techniques and practices are appropriate for the sample type and style of mineralisation. • Individual field soil samples are stored in numbered, sealed plastic sample bags for transport and at the laboratory. • No geophysical tools were used to determine any element concentrations. • Reference standards and blanks were inserted in sample batch submitted to ALS Results indicate satisfactory accuracy and precision was achieved. Verification of sampling and assaying • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, and data storage (physical and electronic) protocols. • Discuss any adjustments to assay data. • The Company’s exploration manager reviewed the assay results. The Company utilises industry standard sampling techniques and accredited independent assay laboratories. • Twinned holes were not drilled. • All sample data was captured in excel spreadsheets and plotted using GIS software. Assay results were merged with the primary data when received electronically from the laboratory using established database protocols. • There are no adjustments to the assay data. The data is received from the lab and is then loaded into DataShed (database) for data validation, verification and storage. • All reported data was subjected to validation and verification by company personnel prior to reporting. The data is checked and verified prior to entering into a master database. All original records are kept on file. CRR has done sufficient verification of the data, in the Competent Person’s opinion to provide sufficient confidence that sampling was performed to adequate industry standards and is fit for the purpose of planning exploration programs and generating targets for investigation. Location of data points • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. A Handheld Garmin GPSMAP 64sx GPS unit was used to locate RC drill collars sample locations with error range of ± 3 to 5 metres for easting and northing. All current data is in MGA94 grid zone 56. Topographic control is adequate as measured by the Handheld Garmin GPSMAP 64sx.

Drill collar spacing was determined by anomalies defined by geochemical, geophysical and geological surveys. Drill collar spacing is shown in the accompanying drill collar tables and drill collar plans. The current density of drilling is not sufficient for resource estimation. Compositing has not been applied Orientation of data in relation to geological structure • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. Most drill holes were designed to intersect at a high angle the strike of coinciding geochemical and magnetic anomalies. No sampling bias is considered to have been introduced during the drill program. Sample security • The measures taken to ensure sample security. The chain of custody for all samples from collection to dispatch to assay laboratory is managed by CRR personnel. The level of security is considered appropriate for exploration surface sampling programs. RC drill samples were collected in the field and placed in a secure, lockable room in the office/residence of the exploration team. Individual samples were collected in calico bags which were placed in batches of three in poly-woven bags that were sealed with cable ties. These were placed on pallets and securely wrapped in plastic stretch wrap. Every pallet was delivered directly to ALS in Brisbane by truck, using a door-to-door service. Audits or reviews • The results of any audits or reviews of sampling techniques and data. Senior management conduct internal audits and reviews. No external audits and reviews sampling techniques and data have been completed. Section 2 Reporting of Exploration Results (Criteria listed in the preceding section also apply to this section.)
