Central Yilgarn Project Located within an underexplored region of the world-renowned Yilgarn Craton, approximately 190 km to the northwest of Kalgoorlie and 160 kms southwest of Leonora. The project area covers an area of over 650 km2, and over approximately 65 km of strike, along the Yerilgee and Evanston greenstone belts. 2. Beasley Creek2 Catalina’s 100% owned highly prospective Beasley Creek Gold Project is located on the northern flank of the Rocklea Dome in the Pilbara Craton of Western Australia. The Project offers two clear discovery pathways — shear-hosted orogenic gold and conglomerate-style gold along a 16km unconformity — neither of which has been systematically drill-tested in more than two decades. 3. Laverton Catalina’s Laverton Project Laverton Project is located within the Laverton Gold Province, an exceptionally mineralised terrain in the Eastern Goldfields. The region hosts several world class deposits of gold, nickel and rare earth elements (REEs) including Sunrise Dam, Wallaby, Granny Smith and the Mt Weld REE deposit, one of the highest grade REE deposits in the world. The tenements present a rare exploration play over multiple greenstone belts with proven mineralisation potential for gold, lithium and Cu-Zn-Ag massive sulphides. With several high-grade gold targets identified and minimal follow- up to date, the exploration potential is significant. Additional Projects PROJECT OVERVIEW Evanston and Yeriligee are Greenstone belts located within an underexplored region of the world-renowned Yilgarn Craton. Over 650 km2 highly prospective greenstone belts. The Company’s planned 20,000 metre drilling program across its Evanston and Yerilgee Projects is scheduled to begin the first week of December 2025, with earthmovers currently mobilising. Phase 1 will comprise of ~7,500m of reverse-circulation (RC) drilling and aircore (AC) drilling, targeting highly prospective gold-hosting structures that have previously returned shallow high-grade intercepts including: Evanston • 48m @ 0.67g/t au from 27m including 21m @ 1.13g/t au from 54m and 3m @ 2.28g/t au from 63m1 • 15m @ 1.5 g/t Au from 12m (incl. 3 m @ 6.7 g/t Au)1 Yerilgee • 17m @ 4.1 g/t Au and 28.0 g/t Ag from 53m, including 4m @ 14.9 g/t Au and 72.2 g/t Ag from 54m1 • 27 m @ 0.6 g/t Au from 6 m, including 2 m @ 2.2 g/t Au, and 1 m @ 9.0 g/t1 • 24 m @ 1.6 g/t Au from 0 m, including 9 m @ 3.3 g/t Au from 12m1 • 16 m @ 1.9 g/t Au from surface (incl. 4 m @ 8.5 g/t Au)1 EVANSTON & YERILGEE 1) 12 December 2024: Updated Acquisition of Yerilgee & Evanston EVANSTON ➢ Part of the Archaean Yilgarn Craton, comprising mafic– ultramafic volcanic rocks intruded by felsic porphyries and cut by major shear zones. ➢ Mineralisation occurs along granite–greenstone contacts and within quartz–carbonate–pyrite veining hosted by magnetite-rich, sheared units. ➢ The belt exhibits multiple structurally controlled gold corridors parallel to regional shears, similar to those hosting long-life operations elsewhere in the Yilgarn. BELT GEOLOGY The Evanston belt represents one of the least systematically tested greenstone corridors between marvel loch and edna may — the same structural system that underpins several multimillion-ounce districts “ EVANSTON LEGHORN ➢ Previous RC drilling at Leghorn returned multiple +1 g/t Au intercepts, with mineralisation remaining open to the north. ➢ Dominated by a large regional north plunging syncline and contains minor felsic intrusions and pegmatites. Significant gold-in-soil anomalies and historical gold working situated along major structural trends and intersections. ➢ Sequence of medium to high grade metamorphosed calc-silicate rocks overlain by ultramafic rock, tholeiitic basalt, banded iron formation and pelitic schist. 48m @ 0.67g/t Au from 27m including 21m @ 1.13g/t Au from 54 m and 3m @ 2.28g/t Au from 63m¹ 7 m @ 0.79 % Cu and 535 ppb Au in massive sulphide from the same zone¹  Leghorn’s structural position and confirmed mineralisation provide a strong basis for the current gold exploration program “ 1) 12 December 2024: Updated Acquisition of Yerilgee & Evanston ➢ Viper South Prospect lies ~10km along strike from the historic Evanston Gold Mine within the T1 Gold Camp. ➢ Comprises a sequence of high-magnesium basalts, ultramafic rocks, and banded iron formation with minor sedimentary units, situated along the regional-scale Evanston Shear Zone that has been intruded by felsic to intermediate intrusions. ➢ Significant gold-in-soil anomalies and historical gold workings occur along the main banded iron formation horizon and in the surrounding rocks.

Soil sampling has defined a coherent gold anomaly with peak values up to 610 ppb Au, well above regional background, and aligned with the Evanston Shear structures¹  “ The close proximity to recently announced intersections by Leeuwin Metals Ltd3 makes this prospect highly exciting 1) 12 December 2024: Updated Acquisition of Yerilgee & Evanston 3) Shallow High-grade Gold From First Drilling At Evanston YERILGEE ➢ Structurally favourable dome-and-shear setting containing high-Mg basalts, ultramafics, banded iron formations (BIFs), and felsic intrusives. ➢ Gold mineralisation hosted within folded BIF sequences intruded by felsic porphyry, with associated pathfinder geochemistry and strong magnetic responses. ➢ Multiple parallel shear zones and fold hinges provide structural traps for gold deposition. BELT GEOLOGY Yerilgee shares the same litho- structural architecture that underpins the world-class Laverton and Mt Margaret gold systems — large portions remain untested below 30 metres “ YERILGEE T8 ➢ Situated along a major regional structure marked by coincident magnetic features and strong pathfinder geochemistry. ➢ Confirmed presence of a gold system hosted within a folded banded iron formation (BIF) package intruded by felsic porphyry. ➢ Coherent mineralised footprint indicated by strong gold anomalism, defined by both soil geochemistry and drilling . ➢ Historical results suggest supergene enrichment and a shallow easterly dip to the mineralisation. 27m @ 0.6 g/t Au from 6m, including 2m @ 2.2 g/t Au, and 1m @ 9.0 g/t Au¹ 17 m @ 0.7 g/t Au from 22m, including 8m @ 1.2 g/t Au from 27m¹ 10m @ 0.8 g/t Au from surface, including 1m @ 6 g/t Au from 11m¹  “ T8 results highlight specific structural and geochemical targets to be tested in the upcoming drill program 1) 12 December 2024: Updated Acquisition of Yerilgee & Evanston YERILGEE T6 - CHICKEN LITTLE, SNOWFLAKE AND MEGATRON ➢ Located centrally within the Yerilgee Greenstone Belt and includes the Chicken Little, Snowflake and Megatron Prospects. ➢ Hosts multiple gold and pathfinder anomalies associated with a series of felsic and lamprophyre intrusions into mafic, ultramafic, and BIF lithologies. ➢ Geochemical data define a fractionated, intrusion-related hydrothermal system with a pathfinder gradient transitioning from Mo– W near a major felsic intrusion to Bi–Te and As–Sb outward from the core. 17m @ 4.1 g/t Au and 28.0 g/t Ag from 53m, including 4m @ 14.9 g/t Au and 72.2 g/t Ag from 54m1 24m @ 1.6 g/t Au from 0m, including 9m @ 3.3 g/t Au from 12m1 16m @ 1.9 g/t Au from surface, including 4m @ 8.5 g/t Au1  “ Strong gold intercepts and multi-element signatures confirm T6 as a well-defined, regionally significant exploration target 1) 12 December 2024: Updated Acquisition of Yerilgee & Evanston +61 8 6165 8858 info@catalinaresources.com.au Level 2/7 Havelock Street West Perth, WA 6005 catalinaresources.com.au ASX:CTN Authorised for release by the Executive Director of Catalina Resources Limited DISCLAIMER This presentation has been prepared by Catalina Resources Ltd (“Company”).
