Catalina intersects wide gold zones in maiden drilling

Announcement PDF ASX Announcement 31 July 2025 Catalina intersects wide gold zones in maiden drilling Highlights • 18m @ 1.16 g/t Au from 127m, including 5m @ 2.3 g/t Au in LVRC02 • Gold hosted in strongly altered quartz–feldspar volcanic rocks, indicative of a large-scale system • Immediate step-out RC and diamond drilling planned to follow open strike and depth extensions Catalina Resources Ltd (ASX: CTN) (‘Catalina’ or the ‘Company’) has delivered wide zones of gold mineralisation from its maiden reverse circulation (RC) drill program at the 100%-owned Laverton Project in Western Australia. The program targeted the Barnicoat Shear Zone – a regionally significant structure interpreted from geophysics that extends through the Company’s E38/3697 tenement. Drilling results and geology LVRC02 was drilled beneath last year’s aircore hole LVAC049, which intersected 28m @ 1.09 g/t Au from 57m including 1m @ 9.69 g/t Au. The new RC drilling has now confirmed that gold mineralisation extends below this shallow intercept into fresh rock, returning 21m @ 1.04 g/t Au from 127m, including 5m @ 2.3 g/t Au. Mineralisation is hosted in bleached quartz–feldspar volcanic rocks containing networks of fine sericite–pyrite– chlorite ± quartz veining. The best grades occur within a steeply east-dipping, tabular envelope of more intense veining and brecciation (Figure 3). Quartz–albite–hematite veining is also common in this zone. This hydrothermal mineralisation remains open in all directions and is interpreted to represent the upper levels of an intrusion-hosted gold system – the style that underpins several major Laverton deposits. Executive Director, Ross Cotton commented; “This is an exciting early result. To intersect this grade and width in such a strongly altered intrusive rock is a textbook indicator of a larger mineralised system. With regional infrastructure, access to mills, and a highly prospective geological setting, we’re fast-tracking follow-up drilling.” Next Steps Catalina has mobilised for immediate follow-up drilling, with a second-phase RC and diamond program to test: • strike extensions of the LVRC02 intercept, and • the depth potential of the mineralisation.

Rare Earth Element Potential Previous aircore drilling also intersected high-grade REE mineralisation in the area, including 4m @ 13,406ppm TREO in LVAC037. RC holes LVRC04 and LVRC05 targeted this zone – assays are pending and could add another dimension to the project’s prospectivity. Project Context The Laverton Project sits within the Laverton Tectonic Zone, a proven gold province hosting more than 25Moz of historical production. Catalina’s ground is strategically located near major operations including Gold Fields Limited (JSE: GFI) (market cap ~ $22B USD) Granny Smith and Wallaby operations and AngloGold Ashanti PLC (NYSE:AU) (market cap ~$25B USD) Sunrise Dam.

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). • • • • Drilling techniques • Catalina Resources completed 5 RC holes 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 2. • 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. MA102 analysis has not been completed. • • Catalina Resources Limited ACN 130 618 683 ASX: CTN 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 air compressors dry the rock out ahead of the advancing drill bit.

Downhole Surveys employed a downhole Gyro making readings every 50m. Sample recovery was assessed visually via the sample size collected into the calico bags. Recovery was usually 8090% but was lower (50%) in wet samples. Ground water caused wet samples occasionally, so splitting of the sample was not possible. In ground sumps were dug 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. Representative 1m samples weighing 20 gms were collected and placed into plastic chip trays for later reference. The recording was done at a level commensurate with the early stage of exploration. The geological information was recorded by a competent person as recognised by JORC. N/A Dry drill samples were collected at the drill collar. After passing through the sample hose and into the drill cyclone the samples pass through a riffle splitter to homogenise the sample and to nullify the effects of particulate gold. After splitting, the sample was collected in a calico bag, ready for assaying. All samples were delivered to the Bureau Veritas (BV) Labs in Kalgoorlie for drying, crushing, pulverising and assay. The samples are considered to effectively represent the rock at the point of collection.
