Announcement PDF ASX RELEASE ASX Announcement 20 November 2024 Catalina Resources is an Australian diversified mineral exploration and mine development company. Directors Executive Chairman and Company Secretary Sanjay Loyalka Director Richard Beazley Director Michael Busbridge Diamond Drilling intersects broad alteration zones with quartz-sulphide veining and brecciation Highlights • A two hole diamond drilling program has been completed at the Rock Lodge Project in NSW • The holes intersected broad alteration zones with quartzsulphide veining and brecciation • Diamond drilling was designed to follow up intersections of gold mineralization in shallow RC drilling • Processing of the diamond core is in progress prior to laboratory analysis for gold and multielements Director Martin Bennett Catalina Resources Ltd (ASX:CTN) (“Catalina” or the “Company”) is ASX Code pleased to announce that diamond drilling at the Rock Lodge Project CTN in the Lachlan Fold Belt, NSW has been completed . CONTACT DETAILS Two diamond holes (SRLRCD001-2) (Figure 3) were drilled for a total Unit 38 18 Stirling Highway NEDLANDS WA 6009 of 351m (NQ core) to test below previous shallow reverse circulation T +61 8 61181672 E info@catalinaresources.com.au (RC) drilling that intersected multiple zones of gold mineralization associated with quartz-sulphide veins . The diamond holes intersected broad zones of alteration with intervals of sulphide veining and quartz-sulphide veining and brecciation hosted by siltstone (Figures 1, 2). The sulphides comprise pyrite and pyrrohotite with minor base metal sulphide (chalcopyrite, galena and sphalerite). The veining crosscuts the foliation in the sediments and suggesting the gold mineralization is related to a late brittle deformation event. The presence of copper and bismuth in previous drill assays from Rock Lodge indicates a possible genetic link to an intrusion at depth. Catalina’s Executive Chairman, Sanjay Loyalka said “the visual results from the drilling are very encouraging with broad intervals of alteration and quartz-sulphide veining logged”.

Page 5 of 22 The diamond core will be cut in half and sampled at 1m intervals through parts of the hole with visual evidence of mineralization. The 1m samples will be submitted to a laboratory based in Orange for analysis of gold by Fire Assay and base metals/multielements by ICP-MS. Assay results will be announced when available. Figure 4: Diamond drill rig in operation at the Rock Lodge prospect, NSW ASX RELEASE. Page 6 of 22 Next Steps The visual results from the drilling are very encouraging with broad intervals of alteration and quartzsulphide veining logged. Processing of the core, sampling and assaying are expected to take approximately 8 weeks. Assay results will be announced when available. After the laboratory analyses are available, the Company will plan additional diamond drilling to in-fill and extend the existing drill coverage as appropriate. Along strike to the north the mineralized sedimentary sequence is covered by tertiary basalt flows. An induced polarization survey may be required to delineate the mineralization under cover. Background The Rock Lodge Project (EL 9155) covers an area of 163 km² and is located 35 km south of Cooma in the Lachlan Fold Belt, NSW. It is prospective for orogenic, Intrusion Related Gold Systems (IRGS). The RC drilling campaign completed by the Company in April 2022 at the Rock Lodge prospect intersected significant mineralisation. The drilling was designed to test prioritised targets consisting of extensive and continuous IP chargeability anomalies that are coincident with very anomalous soil and rock chip geochemistry.

Catalina RC drilling program 2022. Catalina’s RC drilling intersected a wide zone of stacked vertical lenses of polymetallic mineralisation. For example, RC hole SRLRC005 intersected four (4) significant mineralised zones over a width of 24m, from 75m to 99m (including 2m @ 2.13 g/t Au and another 2m @ 2.12 g/t Au)1. At the end of hole at 102m, rocks were still pervasively hydrothermally altered (pyrite, silica, sericite) suggesting that ASX RELEASE. Page 7 of 22 additional downhole zones may have been intersected if excessive water flows had not stopped drilling. West of SRLRC005, Catalina’s drilling has intersected mineralisation in SRLRC002 including 8m @ 1.08 g/t Au1. The geochemical signature of the mineralisation suggests a high temperature hydrothermal fluid may have been responsible. Apart from Au and Ag, the mineralisation includes varying amounts of Bi, As, Cu, Sb, Pb, Cd and Zn. The intersections from Catalina’s drill holes in 2022, SRLRC002 to SRLRC005 in addition to previous drilling by Alt Resources (holes MYRC001-6), constitute a very wide (60m) mineralised envelope of stacked vertical lenses of significant polymetallic sulphide. Two hundred meters to the north, IP anomalies and similar anomalous rock chip geochemical signatures, suggest the mineralisation envelope may be continuous at least to this area. As the envelope is open in all directions further drilling focusing on the continuity, depth and lateral extent of the stacked veins represents a high priority drill target for Catalina. The gold, bismuth and copper mineralisation at Rock Lodge is interpreted to have an affinity with the Intrusion Related Gold System (IRGS) style of mineralisation. There is potential at depth for bulk tonnage gold mineralisation associated with an intrusion. Characteristic features of IRGS mineralisation include sheeted veins containing gold with elevated bismuth, arsenic, silver, copper, lead, zinc and tin. The systems are commonly geochemically zoned around a central intrusion. They can also have elevated sulphide which can be detected with induced polarisation (resistivity lows). Many of these features are present at Rock Lodge. The most recent diamond drilling program is the first test of the mineralized system at depth.

Commentary Catalina Resources – SRLRCD001-2 • Catalina Resources has completed two NQ diamond drill holes for 351m at it’s Rock Lodge Project, near Cooma NSW. • Drilling is located within Catalina’s EL9155 and was completed in November 2024. • Sampling of the diamond holes will be conducted by taking 1m half core samples through mineralized intervals downhole. • The core will be cut on the orientation line or where the orientation line was not defined the core will be cut 90 degrees to bedding/foliation. • The portion of half core selected for analysis will be consistent downhole to remove sample bias (right of the orientation line). • 1m half core samples are of consistent volume and approximately similar weight. • Quality control of the assaying will comprise the insertion of industry (OREAS) standards (certified reference material) every 40th sample. • Samples will be sent to a laboraory in Orange, NSW. • Samples will be crushed and then pulverized so that 75% of the sample passes 75µm. • A representative sample of the pulp will be assayed for gold using Fire Assay. Multielements will be assayed by using Aqua Regia followed by ICP-MS analysis. Alt Resources – MYRC001-6 • All appropriate measures were taken to ensure sample representativity during drilling. • Samples were collected using a cone splitter attached to the drill rig. • 1m samples were taken downhole from which the most mineralized intervals were submitted for analysis based on visual logging. • A 2kg sample was pulverized at the ASX RELEASE.
