Announcement PDF ASX Announcement 19 September 2025 RC drilling confirms gold and REE mineralisation at Laverton Highlights • REE anomalism intersected in a maiden 5-hole RC drill program near Mt Weld, including 12m @ 5828 ppm TREO (with 4m @ 1.19% TREO) in LVRC04. Multiple intervals above 1000 ppm TREO in both LVRC04 and LVRC05. • Structurally hosted hydrothermal gold system confirmed, with anomalous multielement geochemistry (Sb, W, As, Bi, Mo, Sc) suggesting high temperature fluids may be originating from a nearby intrusive body. • This REE metal signature distinguishes Catalina’s Laverton Project as a unique mineralising environment, complementing the established gold potential. • Follow up extensional gold drilling is underway, with REE testing integrated into the drilling workflow via portable XRF field analysis. • Metallurgical test work to be undertaken at ANSTO, Australia’s national authority on critical minerals processing and a global leader in REE recovery research Catalina Resources Ltd (“Catalina” or “the Company”) is pleased to advise that final results pending from a recent five-hole RC drilling program within the Laverton Project have confirmed the presence of a structurally hosted high temperature mineralising system. The geochemical signature is consistent with major Eastern Goldfields deposits, including Wallaby, Granny Smith and Sunrise Dam, illustrated in Figure 1. The RC drilling program – carried out in July 2025 – targeting both gold and REE mineralisation, has now received all remaining results. Previously announced results, targeting gold, returned intercepts such as 18m @ 1.16 g/t Au from 127m, including 3m @ 3.41 g/t Au (LVRC02) ¹. Before the RC drilling, air core drilling intersected 28m @ 1.09g/t Au from 57m (LVAC049) ². 1 See ASX Announcement Dated 31 July 2025: Catalina Intersects Wide Gold Zones in Maiden Drilling 2 See ASX Announcement Dated 8 January 2025: Re-Analysis Upgrades Gold and REE Intersections at Laverton Catalina Resources Limited ACN 130 618 683 ASX: CTN T: 61 8 6165 8858 E: info@catalinaresources.com.au A : Level 2 / 7 Havelock Street West Perth WA 6005 Australia Page 1 of 15 catalinaresources.com.au In holes targeted to gold mineralisation, LVRC01, LVRC02 and LVRC03, anomalous multi-elements including Sb, W, As, Bi, Mo and Sc were also intersected, pointing to laterally continuous mineralisation possibly extending to depth. This geochemical fingerprint is characteristic of high-temperature, graniterelated gold systems that have supported some of the Goldfields’ largest mines. Figure 1. Regional location diagram of the Laverton Gold Project and E38/3697. Importantly, rare earth anomalism was also recorded in holes LVRC04 and LVRC05, with a best interval of: LVRC04 LVRC05 ➢ 12m @ 5828 ppm TREO from 64m including 4m @ 1.19% TREO at 68m ➢ 12m @ 2398 ppm TREO from 20m Catalina Resources Limited ACN 130 618 683 ASX: CTN ➢ 8m @ 2137 ppm TREO from 24m ➢ 8m @ 1935 ppm TREO from 52m T: 61 8 6165 8858 E: info@catalinaresources.com.au A : Level 2 / 7 Havelock Street West Perth WA 6005 Australia Page 2 of 15 catalinaresources.com.au Other intercepts include: LVRC04 LVRC05 ➢ 4m @ 804 ppm TREO from 56m ➢ 16m @ 1531 ppm TREO from 20m ➢ 16m @ 1425 ppm TREO from 44m ➢ 4m @ 1108 ppm TREO from 100m Catalina notes that the REE anomalism observed in LVRCC04 and LVRC05 drilling builds on results previously reported from earlier aircore programs. AC drilling returned multiple zones of REE enrichment, such as: • • 9m @ 7,565 ppm TREO from 47m, including 4m @ 13,406 ppm (1.34% TREO) from 49m in LVAC037 ²; and 5m @ 4,880 ppm TREO from 63m, including 1m @ 10,689 ppm (1.06% TREO) from 66m in LVAC044². The REE mineralisation occurs in a flat-lying saprolite rich clay horizon beneath a 15-20m blanket of transported colluvium, illustrated in Figure 2. The new RC results confirm that this anomalism is both repeatable and geologically consistent, further strengthening the case for Mt Weld intrusive influence. These results provide the first indication of REE fertility in the weathered profile at the Laverton Project. Figure 2: Drilling cross section, A-A', illustrating anomalous REE geochemistry. The location of this section is shown in Figure 3.

Collar coordinates and specifications of the RC drilling is in Appendix 1. All downhole REE assays of the RC holes targeting REE anomalism (LVRC04 and LVRC05) are in Appendix 2. Figure 3: Area of anomalous geochemical gold halo interpreted from previous aircore drilling. Location of RC holes LVRC01 – LVRC05 is also shown. Drilling also intersected anomalous neodymium (Nd₂O₃ at 0.15%) and praseodymium (Pr₂O₃ at 490 ppm) within the high-grade REE zone in LVRC04 (4m @ 13406ppm TREO). Nd and Pr are critical rare earths used in permanent magnets for electric vehicles and renewable energy technologies, highlighting the project’s broader critical minerals potential. Geological review indicates that REE anomalism may reflect both Mt Weld-related fluids and underlying granite-derived clays. This REE metal signature distinguishes Catalina’s Laverton Project as a unique mineralising environment, complementing the established gold potential. To ensure value is fully understood, metallurgical test work will now be undertaken at the Australian Nuclear Science and Technology Organisation (ANSTO), Australia’s national authority on critical minerals processing and a global leader in REE recovery research. While gold remains Catalina’s primary exploration focus, the REE results provide an additional layer of opportunity for existing shareholders. REE analysis has been integrated into the ongoing workflow of the gold drilling using portable XRF analysis and targeted laboratory assays.

The confirmation of a mineralising system, supported by multi-element geochemistry and rare earth anomalism, reinforces the quality of the ground we are exploring. While our immediate focus remains on advancing the gold potential, the presence of REE enrichment adds an additional dimension of interest and opportunity for Catalina.” This announcement has been authorised for release by the Executive Director.

catalinaresources.com.au JORC Code, 2012 Edition – Table 1 Criteria JORC Code explanation Commentary Sampling techniques • • • • • Drilling 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 mineralisation 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 mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. 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). Catalina Resources completed 5 RC holes near Mt Weld, Laverton over the period 15 July 2025 to 19 July 2025. • Drill samples were collected by Reverse Circulation (RC) drilling. Depths for each hole drilled are provided in Appendix 1. • RC drilling was used to obtain 1m samples using a Meztke Cone Splitter in calico bags and weighing 2 to 3 kg each. All samples were delivered to the Bureau Veritas (BV) Labs in Kalgoorlie. • In the lab, each sample was weighed, sorted and dried and then pulverised to 80% passing 75 µ. A 30-gram split was obtained for fire assay for the gold analysis. • After fire assay analysis, samples were transported to BV labs in Perth. • In Perth, a total of 47 elements is reported by the MA102 (mixed acid) analytical technique, including Cu, Pb, Zn, Bi, As, Ag, Ni, Sb and REEs. • The samples are considered to effectively represent the drilling at the point of collection. Sampling included Catalina Resources standard QAQC procedures. • Quality control of the assaying comprised the collection of a duplicate sample every hole, along with regular insertion of industry (OREAS) standards (certified reference material) and blanks. • Assay results have been received for all holes. • • • • • Drill sample recovery • • • Logging • • Catalina Resources Limited ACN 130 618 683 ASX: CTN Method of recording and assessing core and chip sample recoveries and results assessed.

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. • 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. • • • • • • Reverse Circulation (RC) drilling was performed by Topdrill from Kalgoorlie, using a 5.25-inch diameter drill bit with 6 m length drill rods with automatic rod handlers. Holes were drilled at an angle of -60⁰. Rig was a track mounted drill rig with onboard compressor rated at 1300 cfm/500 psi and a booster compressor. RC drilling produces dry rock chips, as large capacity air compressors dry the rock out ahead of the advancing drill bit. RC drilling achieves better penetration than RAB or aircore and is more cost effective than diamond drilling. However, excessive ground water can slow drilling rates. Downhole Surveys employed a downhole Gyro making readings every 10m. Sample recovery was assessed visually via the sample size collected into the calico bags. Recovery was usually 80-90% but was lower (50%) in wet samples. Ground water (not salty) caused wet samples occasionally, so splitting of the sample was not possible. In ground sumps were dug prior to drilling commencing, to collect the excess groundwater expelled by the rig. Catalina Resources does not anticipate any sample bias from loss/gain of material from the drill rig cyclone. Geological logging of drill chips was undertaken. Sample number, carbonate content, magnetite content, sulphide content, lithology, depth, GPS location was recorded. No geotechnical logging was possible as the RC drilling method does not allow RQD recording. Geological logging was qualitative at 1m intervals and was recorded at the sample depth.
