CENTRAL YILGARN EVANSTON AND YERILGEE PROJECTS PROJECT OVERVIEW The Evanston and Yerilgee Projects are named after the greenstone beltsin which they are situated. These beltsare located within an underexplored region of the world-renowned Yilgarn Craton. Mineralisation potential: Au, Fe, Li, Ni, Cu-Zn-Ag massive sulphides. Over 650 km2 (combined) highly prospective ground. Evanston: Historical drillingreturned 15 m @ 1.5 g/t Au (incl. 3 m @ 6.7 g/t Au) at Viper and 48 m @ 0.6 g/t Au (incl. 21 m @ 1.3 g/t Au) at Leghorn, confirming system fertility1 . • Numerous shallow (<30 m) AC and RAB holes indicate mineralisation open at depth and along strike. Yerilgee: Hosts multiple camp-scale targets (T6–T8, T11) defined by gold-in- soil trends and shallow high-grade intercepts. • Stand-out historical results1 include: • 17 m @ 4.1 g/t Au & 28 g/t Ag (incl. 4 m @ 14.9 g/t Au) – Chicken Little • 16 m @ 1.9 g/t Au from surface (incl. 4 m @8.5 g/t Au) – Snowflake • 9 m @ 2.6 g/t Au (incl. 3 m @ 7.1 g/t Au) – Megatron • Surface geochemistry outlinesa 20 km × 2 km gold–pathfinder anomaly, with multiple untested magnetic–structural features. EVANSTON & YERILGEE EVANSTON • Part of the Archaean Yilgarn Craton, comprising mafic– ultramafic volcanic rocks intruded by felsic porphyries and cut by major shear zones. • Mineralisation occursalong 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 OFTHE LEAST SYSTEMATICALLY TESTED GREENSTONE CORRIDORS BETWEEN MARVEL LOCH AND EDNA MAY — THE SAME STRUCTURAL SYSTEM THAT UNDERPINS SEVERAL MULTIMILLION-OUNCE DISTRICTS. “ EVANSTON EXPLORATION STRATEGY Systematic RC drilling to extend mineralisation at Viper North and South, targeting depth and strike continuity. Soil geochemistry and mapping to refine anomalies at Evanston South and T1E, integrating structural and lithological data. Deeper RC programs at Leghorn to follow up significant shallow intercepts and untested northern extensions. Focused on cost-efficient, high-impact drilling across multiple gold-bearing corridors to validate large-scale potential. YERILGEE • Structurally favourable dome-and-shear setting containing high-Mg basalts, ultramafics, banded iron formations (BIFs), and felsic intrusives. • Goldmineralisation 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 — YET LARGE PORTIONS REMAIN UNTESTED BELOW 30 METRES. “ YERILGEE EXPLORATION STRATEGY Follow-up AC/RC drilling at Chicken Little and Snowflake to define strike continuity and depth potential. Integrate magnetic, structural, and geochemical datasets to prioritise drill programs. Infill and extension soil programs across Auger 1–3 and T8 to delineate untested magnetic–structural targets. Advance T6 and T8 to drill-ready status, aligned with CTN’s strategy of building multi-district discovery leverage within the Laverton and Yilgarn belts. LAVERTON HALO PROSPECT PROJECT OVERVIEW The Laverton Gold Project is strategically located in the Laverton district, adjacent to world-class operations including AngloGold Ashanti’s Sunrise Dam, Gold Fields’Wallaby and Granny Smith gold mines, and Lynas Rare Earths’ Mt Weld deposit. Collectively, these operationshighlight the proven endowment of the Laverton Tectonic Zone and its ability to host large, long-lived gold deposits. Of particular interest to the Company at Laverton is its budding Halo Project; which, whilst still in early stages of exploration, presents numerousencouraging geological factors justifying strategic focus. RC and AC drilling campaignsat the Halo site have yielded promising results, including: • 44m @1.01g/t Au from 44m in LVAC0492 incl. 4m @ 2.22g/t Au from 48m 4m @ 1.96g/t Au from 64m 8m @1.45g/t Au from 72m • 18m @1.16g/t Au from 126m, incl. 5m @2.3g/t Au (LVRC02)3 • 17m @0.90g/t Au from 44m (LVRC06)4 • 2m @3.79g/t Au from 190m (LVRC07)4 • 2m @2.55g/t Au from 58m (LVRC08)4 • 1 m @ 11.50g/t Au from 114m (LVRC10)5 • 2 m @ 3.13g/t Au from 48m (LVRC12)5 LAVERTON HALO • The Barnicoat Shear Zone is north-south trending, major regional gold-hosting geological feature in the Laverton region of Western Australia. • The shear zone varies between 10-100m in width and is located at the contact between mafic andfelsic rocks. • This shear zone isa key target for gold exploration and contains several golddeposits. • This includes the likes of the nearby Mon Ami Resource. BARNICOAT SHEAR ZONE POSITIONING THE LAVERTON PROJECT IS STRATEGICALLY PLACED WITHIN ONE OF AUSTRALIA’S MOST PRODUCTIVE GOLD DISTRICTS, ALONGSIDE ESTABLISHED OPERATIONS AT SUNRISE DAM, WALLABY AND GRANNYSMITH. “ LAVERTON-HALO EXPLORATION STRATEGY All assays will be integrated into data interpretations, assessing mineralisation continuity and grade distribution at Project. Outcomes will seek to inform follow up drilling, anticipated focus on strike extensions and continuity testing to the north, south, and east of 6810850N. Petrographic studies will be carried out concurrently to grow knowledge of host lithologies, alteration assemblages, and sulphide development PILBARA BEASLEY CREEK PROJECT PROJECT OVERVIEW The Beasley Creek acquisition establishes Catalina’s first district-scale footprint in the Pilbara, creating a complementary growth hub to its Yilgarn and Laverton portfolios. 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. Western Australia’s most productive gold provinces. Historical drillingintersected up to 4m @11.5 g/t Au (RRC15)4 with multiple additional anomalous soil, stream, and rock chip results. Comprehensive exploration database (1,300+ samples, 2,323 line-km aeromagnetics, detailedmapping) provides immediate leverage for reinterpretation and targeting. BEASLEY CREEK BEASLEY CREEK • Licence on northern flank of the Rocklea Dome – a geological feature comprising ancient Archean and later intrusions. • Bedrock geology of monzogranite and mafic/ultramafic bodies – in Australia’s Pilbara Craton. • Two distinct styles of gold potential at Beasley, a structurally controlled ‘orogenic’gold hosted in Archean greenstones, quartz veins and shear zones show strong anomalism. • Conglomerate-style gold along the Hardey Formation unconformity, a 16 km corridor where coarse sedimentshave the potential to trap and concentrate gold at surface contacts. FAVOURABLE GEOLOGICAL SETTING BODES STRONG NEAR-TERM GROWTH OPPORTUNITY BEASLEY CREEK COMES WITH A COMPLETE DATASET AND PROXIMITY TO ESTABLISHED OPERATIONS AND INFRASTRUCTURE, PROVIDING LOW-COST OPTIONALITY FOR DEVELOPMENT AND THE POTENTIAL TO ACCELERATE VALUE CREATION. “ BEASLEY CREEK EXPLORATION STRATEGY Immediate priority to review historical data to refine and rank targets. Initial program to be run, await assay results from lab to gain baseline understanding of project from modern drilling. Outcomes of data review will inform drill program design, scale and target areas. Future steps at Beasley Creek will be determined by outcomes of initial drilling program.
