Announcement PDF Page 1 Updated Announcement - Breakaway Dam: Core Drilling Appointed; Follow-Up VMS Drilling to Commence Catalina Resources Ltd (ASX: CTN) (‘Catalina’ or the ‘Company’) attaches an updated version of its announcement dated 9 February 2026, titled “Breakaway Dam: Core Drilling Appointed; Follow-Up VMS Drilling to Commence”. The update incorporates supplementary information relating to the historical drilling data and associated disclosures, including: 1. Insertion of a drill results table disclosing the relevant historical assay results for figure 2 which was previously disclosed by Forrestania Resources Limited (AXS: FRS). 2. Insertion of drillhole specifications (Appendix 1) for the holes from which the core photograph shown in Figure 2 was derived. 3. Inclusion of a relevant JORC Table (Appendix 2) and Competent Persons Statement in relation to the drilling and assay results. The historical results referenced in the amended announcement were publicly released by FRS prior to Catalina’s acquisition of the project. At the time of acquisition, the individual intersections related to figure 2 were not considered material in isolation given their tenor and widths, however subsequent geological review (since acquisition) has highlighted that the presence of sulphide mineralisation provides useful technical context supporting the interpreted VMS system. The additional disclosure has been included to provide full technical context in accordance with JORC reporting requirements. The inclusion of this information does not change the Company’s previously stated exploration strategy or investment view. The release of this document to the market has been authorised by the Board of Catalina Resources Ltd.

ASX Announcement 17 February 2026 Page 1 Breakaway Dam: Core Drilling Appointed; Follow-Up VMS Drilling to Commence HIGHLIGHTS ➢ Core Drilling Pty Ltd appointed to undertake an upcoming drilling program at the Breakaway Dam Copper VMS Project in Western Australia ➢ An initial drilling program of approximately 3,000m of RC drilling has been finalised with mobilisation occurring imminently ➢ Recent drilling and downhole EM surveys have confirmed a copper-bearing sulphide system consistent with a VMS setting, providing a robust technical foundation for follow-up drilling ➢ Multiple strong electromagnetic conductors have been identified, with previous drilling interpreted to have intersected the margins rather than centres of conductive sulphide bodies ➢ The upcoming program will systematically test priority EM plates and along- strike/down-plunge extensions, representing the next phase of focused evaluation of the Breakaway Dam mineralised system Catalina Resources Limited (“Catalina” or “the Company”) is pleased announce that it has appointed Core Drilling to support its upcoming drill program at Breakaway Dam Copper VMS Project, located in Western Australia (figure 1). The initial program is expected to comprise approximately 3,000 metres of RC drilling, with scope to expand subject to specialist geological advice and results as drilling progresses. The program is designed to provide systematic follow-up to recent drilling and geophysical work that confirmed the presence of a copper-rich volcanogenic massive sulphide (VMS) system at Breakaway Dam1 . Executive Director, Ross Cotton, commented: “Breakaway Dam is entering a focused phase of exploration aimed at advancing a copper-rich VMS system with clear potential for further growth. This drilling program is designed to test the continuity and extent of mineralisation and to assess whether the system remains open along strike and at depth. The program builds directly on recent drilling and geophysical results and targets the most compelling areas identified to date, as the Company moves to the next stage of evaluating the scale and development potential of the system” ASX Announcement 17 February 2026 Page 2 Figure 1. Breakaway Dam Regional Location SUMMARY OF RECENT DRILLING RESULTS1 ➢ Previous drilling at the Breakaway Dam Project has confirmed the presence of a copper-bearing sulphide system consistent with a VMS setting. ➢ Mineralisation occurs within a defined stratigraphic position in mafic volcanic rocks and is interpreted to be distributed across multiple sulphide layers, reflecting both primary deposition and subsequent structural modification. ➢ An initial drilling program comprising four diamond drill holes, supported by downhole electromagnetic (DHEM) surveys on three holes, intersected sulphide mineralisation within the target stratigraphic position and identified multiple strong electromagnetic conductors. ➢ Interpretation of the DHEM data indicates that several drill holes intersected the margins of conductive sulphide bodies, rather than their centres. Subsequent drilling intersected sulphide- rich intervals dominated by pyrrhotite with minor chalcopyrite, providing important geological and geophysical constraints on the geometry and distribution of the mineralised system. ➢ Drilling intersected copper- and zinc-bearing sulphide mineralisation across multiple holes, with intervals ranging from narrow high-grade lenses to broader zones of moderate-grade mineralisation (figure 3). Purpose of the Upcoming Drilling Program Following confirmation of a copper-rich volcanogenic massive sulphide (VMS) system and identification of multiple strong electromagnetic conductors, the Company is advancing to the next phase of exploration at the Breakaway Dam Project. Page 3 A preliminary drilling plan has been prepared to test priority electromagnetic plates interpreted from modelling around BDCDD2503, together with systematic step-out drilling along strike to assess continuity of the target horizon. The upcoming drilling program is focused on testing the centres of high-conductance plates that were either untested or only partially tested by earlier drilling. These conductors are considered priority targets and represent the most compelling opportunities identified to date to further evaluate the extent, geometry and sulphide tenor distribution of mineralisation within the system. Figure 2. Sulphide rich zones in BDCDD2503 at 170.5m-172.5m downhole and 194.9m-195.9m downhole (for results refer appendix 1) In addition, drilling will extend testing along strike and down-plunge from existing intersections, with the objective of assessing whether sulphide mineralisation continues beyond the approximately 700 m strike length defined to date. Follow-up downhole electromagnetic (DHEM) surveying is planned as part of the program to further refine targeting as drilling progresses. This approach reflects a transition from system confirmation toward systematic evaluation of the most prospective parts of the mineralised horizon. The Company views this drilling phase as an important and high-impact step in advancing the Breakaway Dam Project, providing a clear opportunity to build on the strong geological and geophysical foundations established during the 2025 exploration campaign. Next Steps Drill targets are currently being finalised, incorporating existing drilling, downhole electromagnetic data and geological interpretation. Page 4 The Company has engaged Core Drilling Pty Ltd to undertake the program, with drilling expected to commence prior to the end of February. Figure 3.

Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (eg 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 mineralization that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘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 mineralization types (eg submarine nodules) may warrant disclosure of detailed information. Reported assay results relate to ¼ HQ core assays which were sent for ICP-OES analysis from a four-acid digest. Sampling involves longitudinally sawing HQ diamond drill core and submission to a laboratory for two-stage crushing down to 2mm then pulverisation to 75 micron. Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diametre, 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). Drilling involved HQ diameter coring with electronic backend core orientation for all runs in competent fresh rock. Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results 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 Core recovery is logged as part of the geological logging process. Zones of partial recovery are logged as such, zones of no recovery are logged as intervals of core loss. Diamond drillers use short runs to maximise recovery in poor ground conditions. Competent core is considered representative. The only risks to the representivity of diamond core relate to selective recoveries in highly Page 8 Criteria JORC Code explanation Commentary preferential loss/gain of fine/coarse material. broken ground or hole cave in. No relationship exists between 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 drill core is geologically logged into a digital database on a metre-by-metre basis with 5cm precision on interval boundaries. Core logging is qualitative. Core photos are taken tray-by-tray for all drilled core. All core is logged in entirety. 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. • 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. Core sampling for assay involves: Longitudinally cutting the core in half with an automated core saw which is appropriate for this style of mineralisation. Half core is subject to two-stage crushing down to 2mm then pulverisation to 75 micron to produce the final assay subsample. Lab duplicate samples are inserted every 50 samples by taking a second 75 micron pulp from the duplicate interval. Blank samples are inserted every 50 samples to monitor for contamination in the crushing and pulverisation stages. Second half core sampling is not used in the exploration stage, however the core is archived should this be required in the future. Quarter HQ core is appropriate for percent- level base metal targets. The sub sampling and crush/pulverisation sizes are appropriate for the material being sampled. 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 including instrument make and model, reading times, calibrations 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 (ie lack of Core sampling will involves: Assay with a four acid digest and ICP-OES finish which is appropriate for copper ore-grade base metal analysis. Four acid digests are considered a near total digest and appropriate for copper mineralisation when low level and over limit methods are applied appropriately. No geophysical tools were used. Certified Reference Materials (CRMs) are Page 9 Criteria JORC Code explanation Commentary bias) and precision have been established. inserted every 25 samples throughout assay batches. Blank samples are inserted every 50 samples. Laboratory duplicate pulps were inserted every 50 samples. Duplicate core (another quarter) samples are not routinely used for exploration-stage samples, but retained core makes this possible at any stage in the future. External laboratory checks (umpire assays) are not routinely used for exploration-stage samples. 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, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. Visual estimates only have been reported. Visual estimates of an experienced and suitably qualified geologist were then verified by a second experienced and suitably qualified geologist. There are no twin holes in this early-stage exploration project. Data is digitally entered into a database with internal validation checks. No adjustment is made to assay data. 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. Collar locations are collected by hand held GPS after drilling is complete which has an accuracy of ±4m. GPS data is reported and stored in the MGA2020 Zone51 UTM grid system. Topographic control is achieved by normalisation against the regional DEM available from Geoscience Australia. Data spacing and distribution • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. The drilling was planned to produce intercepts 70m apart and roughly that same distance away from the nearest historical drilling. No mineral resource estimate is planned at this stage; much more drilling is required first. No sample compositing has 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 The designed intercept angles are at a high angle to the target and therefore produce no bias in sampling. Page 10 Criteria JORC Code explanation Commentary should be assessed and reported if material. Sample security • The measures taken to ensure sample security. Samples were transported from a secure yard in Kalgoorlie to the laboratory in Perth via a reputable courier with industry standard security measures. Audits or reviews • The results of any audits or reviews of sampling techniques and data. No audits or reviews have been conducted at this stage. Section 3 Reporting of Exploration Results (Criteria listed in the preceding section also apply to this section.) Criteria JORC Code explanation Commentary Mineral tenement and land tenure status • Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. The Breakaway Dam Copper Prospect is located on E29/1037. The Company has entered into a binding agreement to acquire the tenement from Forrestania Resources Ltd The project is on Nyalpa Pirniku determined native title land. There are no private royalties or encumbrances on E29/1037. The tenement is in good standing with all obligations and minimum expenditure commitments met. Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. Historical prospecting pits of an unknown vintage tested surface copper expressions at Breakaway Dam. Modern exploration of the area for copper began with soil sampling from 1997 by Delta Gold and subsequent soils and RAB drilling by Pelican Resources up to 2004. Amex Resources worked the prospect from 2007 to 2010 with surface moving loop electromagnetics (MLEM) and RC drilling of modelled conductors. Diamond drilling returned percent level copper intercepts over narrow widths and follow-up downhole electromagnetics (DHEM) refined the electromagnetic model with modelled offhole conductors, one of which is large and highly conductive. In 2025 Forrestania Resources undertook surface sampling and a general Page 11 Criteria JORC Code explanation Commentary geochemistry review through Camp Oven Exploration. That review concludes that the project is highly anomalous in copper pathfinder elements consistent with volcanogenic massive sulphide (VMS) mineralisation. Geology • Deposit type, geological setting and style of mineralization. The Breakaway Dam Prospect is within the Alexandra Bore Greenstone Belt, an isolated sliver of monzogranite–bound greenstone that hosts multiple copper-bearing gossanous outcrops and pegmatites. The target stratigraphy is a package of metasedimentary rocks layered between two granitoid bodies, both of which are dominated by coarse variably foliated granite with common aplitic and pegmatitic secondary phases. The metasedimentary package includes quartzites, metapsammites and metasedimentary schists. Where bedding is apparent it is very tightly folded. An amphibolite package abuts the western granitoid margin and varies in thickness from 50m or more to completely absent. The amphibolite usually appears massive however highly strained zones overprinting some inherent texture were also observed. The entire target corridor is highly strained. The structural grain of the area is subvertical. Surface structural measurements of the orientation of the main foliation are universally very steeply dipping. The target style of mineralisation is Volcanogenic Massive Sulphide (VMS) and surface geochemistry, particularly elevated base metals, is consistent with this style of mineralisation. 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: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. All holes designed for this drill program are listed in appendix 1 of this report Page 12 Criteria JORC Code explanation Commentary • 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 (eg 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. Assay grades reported in this project are length weighted only. Base metal sulphide mineralisation is most precisely reported when composited samples are both length and density, but that data is not yet available for these intercepts. 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 (eg ‘down hole length, true width not known’). All drilling is at a high angle to the target. True widths are estimated based on the orientation defined by the plane connecting recent mineralisation intercepts. These true widths are estimates only and more data may refine the geometry of mineralisation allowing for better estimates of true width. 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. Appropriate maps displaying all the data points and anomalous values are provided in the body of the report. 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. All four holes drilled are discussed in this announcement Historical drilling is shown for reference in the main body of this report which was reported according to JORC 2004, but can not be independently verified by Catalina Resources. Other substantive exploration data • Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; The targeting of this program is based on electromagnetic surveys acquired and modelled between 2007 and 2010. These surveys provided the basis for the drillhole design. No metallurgical geotechnical or other work has been completed at this stage.
