Catalina Resources Limited (ASX: CTN) (Catalina or the Company) is pleased to announce that it has entered into a binding agreement to acquire the Badja Gold Project (Badja or the Project) in Western Australia's Mid-West region. The acquisition materially advances Catalina's Mid-West gold strategy, adding an established resource base, granted mining tenure and significant exploration upside to its project portfolio. High-grade gold mineralisation remains open along strike and at depth, supporting opportunities for resource expansion and future development. ASX Announcement 10 NOVEMBER 2026 Page 2 Executive Director, Ross Cotton, commented: “Badja is a standout addition to our Mid-West gold strategy, and it comes with almost everything you want in a growth asset. It brings around 90,000 ounces of gold and significant exploration target on granted mining leases, anchored by Gnows Nest, a historic mine that produced nearly 28,000 ounces of gold at more than 20 grams per tonne. It sits within trucking distance of multiple gold processing plants. And it offers a second commodity opportunity, with significant tungsten identified alongside the gold at Monte Cristo and Flying Emu. The upside is what really excites us. Very little modern work has been done, the mineralisation is open along strike and at depth, and high-grade gold has already been hit below the old workings. We’re moving fast. An aggressive but targeted drilling program at Gnows Nest is being prepared now, aimed squarely at growing the resource and exceeding our exploration target. With granted tenure, nearby infrastructure and the support of Shaw and Partners and our shareholders, Catalina has the platform to unlock Badja’s potential and build real scale in the Mid-West.” Figure 1 – Location of the Badja Gold Project relative to Catalina’s Mid-West portfolio and regional gold operations Page 3 BADJA GOLD PROJECT - AN ADVANCED GOLD ASSET WITH IMMEDIATE RESOURCE GROWTH FOCUS The Badja Gold Project is located within the Yalgoo Mineral Field of Western Australia and comprises the Gnows Nest, Monte Cristo, Flying Emu and Water Tank gold deposits, together with several additional exploration prospects. The Project is located approximately 110km south-west of Mount Magnet, within 100km of multiple gold processing plants. The tenement package comprises two granted Mining Leases, one pending Mining Lease and three Exploration Licences, covering approximately 39km², with access via Great Northern Highway and the Geraldton-Mount Magnet Road. MINERAL RESOURCE ESTIMATE The four principal gold deposits host a combined Indicated and Inferred JORC 2012 Mineral Resource Estimate of 1.11 Mt @ 2.52 g/t Au for 90,358 oz of contained gold, providing an established resource base with significant potential for further growth. The Gnows Nest and Monte Cristo deposits currently host an existing Indicated Mineral Resource of 0.92 Mt @ 2.77 g/t Au for approximately 82,208oz. Flying Emu hosts an Inferred Mineral Resource of 0.12 Mt @ 1.75 g/t Au for approximately 6,500oz and Water Tank hosts an Inferred Mineral Resource 0.08 Mt @ 0.66 g/t Au for approximately 1,650oz. Figure 2 – Badja Gold Project tenements, Mineral Resource deposits, prospects and historical drilling Page 4 Further information supporting the Mineral Resource Estimate, Exploration Target and historical Exploration Results, including the applicable JORC 2012 disclosures, is provided in Annexure 2.

The Gnows Nest and Monte Cristo Mineral Resource Estimates were prepared on the basis of potential initial open-pit mining followed by underground mining, supported by preliminary mining assessments and indicative metallurgical testwork. Conventional carbon-in-leach processing has been assumed as a potentially suitable treatment method, subject to further technical evaluation. The Flying Emu and Water Tank Mineral Resources are classified as Inferred and reported above a 0.5 g/t Au cut-off grade. These estimates incorporate historical exploration data and are subject to lower geological confidence, with no detailed mining or metallurgical assumptions applied at this stage. All reported estimates are Mineral Resources and not Ore Reserves. Further drilling, technical studies and evaluation will be required before any development decision. Additional information regarding the estimation methodologies, resource classification, cut-off grades and material assumptions is provided in Appendix 1, with supporting JORC Table 1 disclosures in Appendix 2. EXPLORATION TARGET The Gnows Nest and Monte Cristo deposits also feature a conceptual Exploration Target of ~0.8–1.7 Mt @ 4.4–5.7 g/t Au for approximately 109,000–303,000oz of contained gold, highlighting the potential to materially expand the current resource base through further exploration and drilling. The potential quantity and grade of the Exploration Target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The Exploration Target is separate from, and additional to, the existing Mineral Resources, and does not constitute a Mineral Resource or Ore Reserve. Importantly, this Exploration Target relates exclusively to Gnows Nest and Monte Cristo and does not include additional exploration potential at Flying Emu or Water Tank, providing further opportunities for resource growth across the broader Badja Gold Project. Page 5 Exploration Targets have been defined for extensions to the existing gold deposits at Gnows Nest and Monte Cristo, highlighting the potential to expand the current Mineral Resource through targeted drilling. The Exploration Targets are based on geological interpretations, historical drilling results, mineralisation geometry and grade characteristics derived from Cadre Geology and Mining Pty Ltd ‘s (Cadre), updated Mineral Resource Estimate.

The Project's location provides Catalina with the opportunity to evaluate multiple potential development pathways, including third-party toll treatment, ore processing arrangements and standalone processing options, subject to metallurgical compatibility, processing capacity, commercial agreements and future technical studies. Significant regional operations and infrastructure include: ➢ Golden Range and Fields Find Gold Projects – Capricorn Metals Limited (ASX: CMM): Recentlyacquiredprojects hosting the Ricciardogold-antimony depositand a Mineral Resource of 2.3 Moz AuEq (31 Mt at 2.3 g/t AuEq), comprising approximately 1.38 Moz of gold and 60 kt of antimony. Under its Range 500 growth strategy, Capricorn is evaluating a proposed 1.5–2.5 Mtpa gold processing facility at Golden Range, potentially establishing a significant new processing hub within the broader Mid-West gold district. ➢ Deflector Gold Mine - Vault Minerals Limited (ASX: VAU): An established operating gold- copper mine and processing facility within the Mid-West region, demonstrating the presence of existing gold processing infrastructure. ➢ Kirkalocka Gold Processing Plant (2 Mtpa): Gylden Resources’ gold processing facility provides significant existing processing infrastructure in proximity to the Badja Gold Project (refurbishment and recommissioning underway). ➢ Mt Gibson Gold Project – Capricorn Metals Limited (ASX: CMM): A significant gold development project that reported a maiden underground Mineral Resource of 684 koz at 3.1 g/t Au in July 2025, further demonstrating the scale of gold mineralisation within the region. Page 6 ➢ Golden Grove Mine – 29Metals Limited (ASX:29M): An established operating copper-zinc-gold mine, highlighting the region's extensive mining history, infrastructure and established mining industry presence. The proximity of Badja to multiple established mining operations, existing processing infrastructure and potential future processing capacity provides Catalina with a range of development options, including opportunities to evaluate the utilisation of regional processing infrastructure. Figure 3 – Badja Gold Project location relative to regional gold processing infrastructure and nearby projects GNOWS NEST – HIGH-GRADE CORE AND INITIAL GROWTH FOCUS The Gnows Nest deposit is a historically mined, high-grade gold system hosted within a north- northwest-trending shear zone. As previously reported by EMU NL (ASX:EMU)¹, LBC Resources modelled the mineralised shear zone over approximately 500m of strike, 1–10m wide and to a vertical depth of approximately 200m. Within the shear, gold is hosted in en-echelon quartz veins within a dextral strike-slip structure extending over approximately 380m of strike (trending 330°–360°). The veins range from 1mm to 1m thick and sit in talc-chlorite schist, within mineralised zones commonly 1–2m wide¹. The system dips moderately west (approximately 57°) and hosts multiple plunging high- grade shoots. Historical underground mining followed the 380m strike length over five levels to a depth of approximately 135m, with high-grade mineralisation identified on the lowest developed level (Level 5)1 . Page 7 Drilling has intersected mineralisation more than 200m down hole, below the historical workings, and the system remains open at depth and along strike. Historical underground mining produced approximately 27,925oz of gold at an average recovered grade of 21.85 g/t Au1 . Historical underground channel sampling at Gnows Nest has identified significant high-grade gold mineralisation within the existing underground workings1 . In a report published by EMU in 20241 , LBC Resources (LBC) identified mineralisation across much of the lowest underground level (Level 5), averaging approximately 19.5 g/t Au over sampled widths of 1.5m. The report identified several of the UG levels, either ended in mineralisation or had identified mineralisation that was not followed up. Selected historical underground channel sampling results include: Channel ID Sampled length (m)* Gold grade (g/t Au) GN_222_48 8.44 37.77 GN_222_64 1.42 88.89 GN_270_22 1.52 71.3 GN_248_4 1.97 31.99 GN_222_60 1.52 42.66 *Note: channel sample length not true width Subsequent drilling by EMU intersected high-grade mineralisation beneath the historical workings, including 2m @ 11.43 g/t Au from 208m, including 1m @ 15.68 g/t Au from 208m (21GNRC232), highlighting the potential for further extensions at depth.

As previously reported by EMU1 , the Monte Cristo deposit is a shear hosted combined hydrothermal gold and tungsten system in which gold and tungsten events have been superimposed on each other. It appears likely that the tungsten bearing event accompanied by disseminated pyrite and magnetite mineralisation would have predated the gold event due to hydrothermal system temperature constraints. However, the two events would have been constrained by the same structural geologic controls and hence, would overlap closely. Gold mineralisation occurs within structurally controlled quartz veins along a northwest-trending shear zone extending approximately 500m along strike, near the contact between banded iron formation (BIF), mafic volcanic rocks and metasediments. Historical drilling has intersected mineralisation at depths of up to approximately 155m (7m @ 2.18 g/t Au from 173m in 21MC018), with the system remaining open along strike and at depth. Page 10 Selected historicalMonte Cristo gold drilling results include: ➢ 3m @ 13.35 g/t Au from 67m, including 1m @ 19.90 g/t Au from 68m (21MC001); ➢ 6m @ 6.51 g/t Au from 120m, including 1m @ 22.77 g/t Au from 121m (21MC011); ➢ 4m @ 9.74 g/t Au from 32m (4m composite sample) (21MC022); ➢ 2m @ 6.47 g/t Au from 69m, including 1m @ 12.38 g/t Au from 69m (21MC002); ➢ 4m @ 3.29 g/t Au from 120m, including 1m @ 5.97 g/t Au from 120m (21MC007); ➢ 6m @ 3.28 g/t Au from 47m, including 2m @ 7.47 g/t Au from 47m (21MC006); ➢ 2m @ 5.80 g/t Au from 101m, including 1m @ 10.30 g/t Au from 101m (21MC011); ➢ 2m @ 5.45 g/t Au from 40m (21MC013); ➢ 4m @ 3.02 g/t Au from 96m (21MC019) (4m composite sample); ➢ 3m @ 2.73 g/t Au from 124m, including 1m @ 4.09 g/t Au from 125m (21MC025); ➢ 3m @ 2.51 g/t Au from 125m, including 1m @ 4.28 g/t Au from 126m (21MC020); ➢ 7m @ 2.18 g/t Au from 173m, including 1m @ 4.09 g/t Au from 173m (21MC018) Figure 6 – Monte Cristo plan view showing significant historical gold and tungsten drill intercepts Page 11 Tungsten opportunity Historical drilling at Monte Cristo has identified significant tungsten mineralisation coincident with gold mineralisation. Subsequent geological interpretation reported by EMU1 indicates that gold and tungsten mineralisation may represent separate, superimposed mineralising events associated with common structural controls. Reported intersections: • 12m @ 0.12% WO₃ from 58m (including 1m @ 0.64% WO₃ from 59m) (21MC001); • 6m @ 0.18% WO₃ from 58m (including 1m @ 0.44% WO₃ from 59m) (21MC002); and • 4m @ 0.14% WO₃ from 28m (21MC003). Catalina considers the identified tungsten mineralisation to represent a significant additional exploration opportunity alongside its primary gold development strategy. The Company intends to advance the tungsten potential through targeted exploration and technical evaluation, with the longer- term objective of defining a Mineral Resource compliant with the JORC Code (2012). To support this work, Catalina has engaged geological consultant Nigel Maund to undertake a comprehensive assessment of the Project's tungsten potential, focusing on geological controls, mineralisation extensions and priority exploration targets with results expected to guide subsequent exploration and drilling activities, complementing the Company's planned gold drilling programs. Figure 7 – Monte Cristo oblique cross section showing interpreted geology and gold–tungsten intercepts in 21MC001, 21MC002 and 21MC011 Page 12 FLYING EMU – THIRD GOLD RESOURCE CENTRE Flying Emu represents a third gold resource centre at Badja, located approximately 1km northwest of Monte Cristo within the same geological formation, quartz veins within sheared mafics in a metasedimentary sequence, as at the Gnows Nest and Monte Cristo deposits and exhibits similar thrust fault and structural deflection in the magnetic signature8 . Historic drilling has identified gold mineralisation over approximately 400m of strike and to a vertical depth of 100m, with the system remaining open along strike and at depth1 . Limited drilling beyond the currently defined mineralised zones provides opportunities for further resource growth. ➢ 9m @ 3.44 g/t Au from 39m, including 2m @ 10.14 g/t Au from 39m (22FERC001); ➢ 1m @ 7.34 g/t Au from 95m (22FERC008); ➢ 2m @ 3.17 g/t Au from 32m (22FERC004); ➢ 3m @ 1.23 g/t Au from 61m (22FERC002); and ➢ 2m @ 1.23 g/t Au from 26m (22FERC009). Shallow historical drilling outside the current Flying Emu Mineral Resource has also returned near- surface gold mineralisation that is not included in the resource and represents a target for follow-up drilling: ➢ 20m @ 1.57 g/t Au from surface, including 4m @ 3.79 g/t Au from 12m (MCRB008); and ➢ 1m @ 8.36 g/t Au from 27m (22BAC100). In addition to the established gold mineralisation, historical drilling at Flying Emu has identified encouraging tungsten mineralisation, highlighting the potential for additional mineralisation within the broader Badja Project. Historical results include: ➢ 1m @ 0.383% WO₃ from 99m (22FERC008) ➢ 1m @ 0.304% WO₃ from 45m (22FERC001) ➢ 1m @ 0.279% WO₃ from 95m (22FERC008) Page 13 Figure 8 – Flying Emu plan view showing significant historical gold and tungsten drill intercepts WATER TANK DEPOSIT The Water Tank deposit lies approximately 800m to the southeast of Monte Cristo along the main structural trend of the Yalgoo greenstone belt within a prominent structural flexure in the greenstones. Numerous historic shafts are also proximal to the Water Tank deposit along the BIF contact, similar to Gnows Nest and Monte Cristo. As previously reported by EMU1 , LBC Resources has modelled mineralised shear zones extending approximately 350–650m along strike and to a vertical depth of 100m, with individual zones typically 1–10m wide. Potential extensions along strike and at depth remain largely untested, providing opportunities for further exploration and resource growth. Selected Historical Water Tank Drill Resultsinclude: ➢ 2m @ 9.94 g/t Au from 51m, including 1m @ 19.35 g/t Au from 51m (21WTH001); ➢ 2m @ 3.77 g/t Au from 51m, including 1m @ 6.01 g/t Au from 52m (21WTH004); Page 14 ➢ 6m @ 1.12 g/t Au from 29m, including 1m @ 2.30 g/t Au from 32m (21WTH005); ➢ 4m @ 1.48 g/t Au from 36m (4m composite sample) (21WTH007); and ➢ 4m @ 2.45 g/t Au from 49m (22WTH022). Historical drilling north of the current Water Tank Mineral Resource has also returned high-grade intervals that are not included in the resource and represent priority targets for follow-up drilling. • 2m @ 4.35 g/t Au from 30m, including 1m @ 7.81 g/t Au from 30m (GN15); • 3m @ 2.28 g/t Au from 38m, including 1m @ 3.66 g/t Au from 38m (GN16); and • 2m @ 3.04 g/t Au from 65m, including 1m @ 5.17 g/t Au from 66m (GN14). Figure 9 – Water Tank plan view showing significant historical drill intercepts Page 15 GROWTH POTENTIAL The Company considers Badja to be a highly prospective area for gold exploration on the basis of previous drilling results, the area’s rich mining history whilst noting that the project has remained relatively under explored since mining was last active. In addition to the opportunity to extend known mineralisation, historical RC drilling completed by EMU Resources NL in 2022 returned several standout intersections which demonstrate highly prospective brownfields potential outside the current estimates. NEXT STEPS – PRIORITISING RESOURCE GROWTH AT GNOWS NEST Catalina is planning a staged exploration campaign of up to 15,000m of RC, diamond and aircore (AC) drilling following completion of the acquisition, focused on expanding the existing gold resource base and supporting an updated Mineral Resource Estimate (MRE). The initial priority will be resource extension drilling at Gnows Nest, targeting potential extensions to the existing high-grade mineralisation along strike and at depth, particularly beneath and adjacent to the historical underground workings. POWs are approved and earthworks are expected to be completed throughout November and December with drilling to commence in January 2027. The program will also incorporate targeted drilling and geological assessment at Monte Cristo, Flying Emu and Water Tank, with activities prioritised according to their potential to contribute to resource growth. Key priorities for the initial campaign include: ➢ Gnows Nest resource extensions: Prioritise step-out drilling along strike and at depth to test extensions to known high-grade gold mineralisation, including beneath the historical underground workings. ➢ Targeted infill drilling: Undertake selective infill drilling where required to improve geological confidence, better define the continuity and geometry of mineralised zones, and support updated Mineral Resource Estimates. ➢ Diamond drilling and technical studies: Complete targeted diamond drilling to improve structural interpretations, obtain bulk density measurements and collect samples for potential metallurgical testwork. ➢ Additional resource growth opportunities: Progress targeted exploration at Monte Cristo, Flying Emu and Water Tank to evaluate extensions to existing mineralised zones and identify opportunities for resource expansion. ➢ Updated geological models and Mineral Resource Estimates: Integrate new drilling results with the historical exploration database to refine geological, structural and mineralisation models and support updated Mineral Resource Estimates. BUILDING A STAGED DEVELOPMENT PATHWAY In parallel with resource expansion, Catalina intends to progress the technical work required to evaluate potential development options at Badja. Page 16 Preliminary mine-planning work undertaken previously has considered potential open-pit and underground mining opportunities across Gnows Nest and Monte Cristo. This work is preliminary and does not constitute an Ore Reserve, Scoping Study, Pre-Feasibility Study or Feasibility Study. Further drilling and appropriate technical, economic and regulatory studies will be required before a development decision can be considered. Processing will form an important component of this evaluation. Catalina intends to consider potential use ofestablished regionalprocessinginfrastructure alongside other developmentscenarios. Nothird- party processing arrangement has been secured, and any such pathway would depend on technical suitability, available capacity, haulage economics and commercial terms. Catalina intends to progress resource expansion, mining studies, metallurgical assessment, geotechnical work and approvals in parallel where appropriate. 18-Month Badja Work Program and Catalysts ACQUISITION TERMS AND FUNDING KEY TERMS Catalina has entered into a binding Share Sale Agreement (SSA) with Badja Gold Pty Ltd (Badja Gold) and its shareholders (Sellers) to acquire 100% of the issued shares in Badja Gold (Acquisition). Badja Gold holds 100% of Coruscant Minerals Pty Ltd (Coruscant), the registered holder of the tenements comprising the Badja Gold Project. Consideration The total upfront consideration for the Acquisition is $6,000,000, comprising: ➢ Cash Consideration: $3,000,000 in cash, payable as follows: • a $20,000 deposit, already paid under the non-binding indicative offer dated 26 August 2026; Page 17 • a $250,000 signing deposit, payable within two business days of execution of the SSA; • $2,600,000 payable at Settlement; and • $130,000 withheld at Settlement pending the outcome of a RevenueWA enquiry into stamp duty on Badja Gold’s earlier acquisition of Coruscant (Withheld Amount). The Withheld Amount will be paid to the Sellers less any duty assessed or retained by Catalina if the duty assessed equals or exceeds it. Both deposits are non-refundable, including if the SSA is terminated, and are credited against the Cash Consideration. ➢ Consideration Shares: $3,000,000 in fully paid ordinary Catalina shares, issued at the same price as shares under the Placement ($0.055 per share), being 54,545,455 shares. Their issue is subject to shareholder approval. ➢ Deferred Consideration: Catalina will pay or issue a further $3,000,000 to the Sellers within 10 business days of the first of the following milestones (Milestone): • Catalina announcing to ASX a JORC (2012) Mineral Resource of at least 160,000 ounces of gold, at a cut-off grade of 1.0 g/t Au or lower, from the Badja tenements; or • production of 50,000 ounces of gold from the Badja tenements. The Deferred Consideration is payable in cash or, at Catalina’s election, in Catalina shares issued at the 10-day VWAP immediately before the Milestone is achieved. Catalina may only elect shares where it is permitted to issue them under the ASX Listing Rules (including any required shareholder approval) and can issue a cleansing notice for them. Otherwise, the Deferred Consideration must be paid in cash. Existing EMU Milestone Obligations Badja Gold acquired Coruscant from EMU in 2025. Under that agreement, which remains in place following the Acquisition, Badja Gold must pay EMU: ➢ $1,200,000 on the Project producing 5,000 ounces of gold; and ➢ a further $1,000,000 on the Project producing a further 5,000 ounces of gold. If, within five years of that agreement, Badja Gold disposes of or deals in its shares in Coruscant, or Coruscant disposes of or deals in the Project or any of the Tenements, both milestone payments become payable regardless of whether the production milestones have been met. After five years and before twenty years from that agreement, any such disposal or dealing is conditional on the incoming party assuming these obligations by deed in favour of EMU. Conditions Precedent Settlement is conditional on: 1. Catalina shareholders approving the issue of the Consideration Shares and any other matters requiring approval to give effect to the Acquisition; and Page 18 2. the parties obtaining all required third-party approvals and consents, including Ministerial consent under the Mining Act 1978 (WA), if required. If the conditions are not satisfied or waived by 5:00pm (WST) on 31 January 2027, either party may terminate the SSA. Settlement and other key terms ➢ Settlement will occur five business days after the last condition precedent is satisfied or waived. ➢ The Consideration Shares will rank equally with existing Catalina shares and will not be subject to voluntary escrow. ➢ Until the earlier of the Milestone being achieved and five years after Settlement, Catalina must keep the tenements in good standing. It must first offer the Sellers any tenement it proposes to surrender. Any buyer of the project must agree to be bound by the Deferred Consideration obligations. PRIVATE PLACEMENT In addition t
