MULTIPLE DRILL-READY OPPORTUNITIES Walk-up targets generated through historical drilling, geophysics and geological reinterpretation. EXPOSURE TO UNDEREXPLORED SYSTEMS Gold and VMS targets with limited modern exploration and significant discovery upside. FUNDED FOR ACCELERATED EXPLORATION Technical review is underway to refine drill-ready targets and progress near-term exploration programs. 4 KIRKALOCKA POSITIONED FOR DISCOVERY, CONSOLIDATION AND DEVELOPMENT LOCATED IN A PROVEN GOLD BELT Located ~50km south of Mt Magnet within the Wydgee-Meekathara Greenstone Belt, Murchison Province. ACCESS TO KIRKALOCKA GOLD PROCESSING PLANT Nearby processing hub with a throughput capacity of 2Mtpa, currently being advanced toward a planned recommencement of operations in 2026 by Gylden Resources Limited. ADJACENT TO KIRKALOCKA GOLD MINE Strategically positioned along the eastern margin of the belt, adjacent to the Kirkalocka Gold Mine, which hosts a reported ~240,000oz Au Mineral Resource. HIGHLY PROSPECTIVE & DRILL-READY Prospective for structurally controlled orogenic gold associated with major shear corridors, greenstone–granite contacts and favourable host rocks. Historical datasets and structural interpretation have defined multiple drill-ready targets across underexplored greenstone stratigraphy. EXCELLENT ACCESS & INFRASTRUCTURE Direct access via the Great Northern Highway and located within a region of extensive historical mining and active exploration. Kirkalocka Project WA | Gylden Resources Gold Operation Gylden Resources | Gold Processing and Toll Treatment WA 5 Kirkalocka Mine and Processing Plant (Glyndon Resources) WARRIEDAR POSITIONED AMONGST ACTIVE REGIONAL OPERATORS POSITIONED BETWEEN MAJOR REGIONAL OPERATORS Landholding within the Yalgoo–Singleton Greenstone Belt, strategically located between Capricorn Metals Ltd tenure and in close proximity to Tungsten Mining NL’s Mt Mulgine Project. PROSPECTIVE GREENSTONE ARCHITECTURE Structurally complex mafic–ultramafic volcanics, sediments and BIF units associated with major shear corridors and favourable gold settings. MULTIPLE WALK-UP EXPLORATION TARGETS Prospective for structurally controlled orogenic gold associated with major shear corridors, greenstone–granite contacts and favourable host rocks. HISTORICAL EXPLORATION IDENTIFIED MULTIPLE STRUCTURES Historical aeromagnetic interpretation and fieldwork identified previously unrecognised structures considered prospective for mineralization. ANALOGOUS TO KNOWN REGIONAL GOLD SYSTEMS Gold mineralisation at Mugs Luck is associated with sheared mafic–ultramafic and BIF contacts comparable to the Monaco, St Tropez and Riviera deposits. Warriedar 6 PITHARA HISTORICAL HIGH-GRADE MINE HIGHLY PROSPECTIVE GEOLOGY Prospective for structurally controlled orogenic gold mineralisation along interpreted shear corridors and BIF units. MULTIPLE DRILL-READY TARGETS Multiple walk-up drill targets identified from historical drilling, artisanal workings and structural reinterpretation. HISTORICAL HIGH-GRADE GOLD PIT Hosts the historical Pithara Gold Pit , which reportedly produced ~9,000oz @ 15.4g/t Au from shallow open pit with potential to extend mineralisation at depth and along strike. OUTSTANDING LOCATION IN THE DALWALLINU BELT ~110km² landholding within the underexplored Dalwallinu Greenstone Belt in a region of increasing exploration and development activity. BROADER REGIONAL EXPLORATION EXPOSURE Includes historical workings near Bolgart, an area of limited modern exploration despite renewed regional activity including nearby work associated with Chalice Mining Limited’s Kings Project JV. Pithara ASX:DRE - Option to Acquire Strategic Landholding in Mid-West 7 TALLERING VMS / COPPER-GOLD DISCOVERY OPPORTUNITY LARGE-SCALE LANDHOLDING ~236km² project covering ~30km strike of the underexplored Tallering Greenstone Belt. ~120km inland from Geraldton, Murchison Province WA. UNTESTED GEOPHYSICAL TARGETS Multiple untested EM and IP anomalies associated with mapped sulphide mineralisation and favourable host rocks remain untested by modern drill programs. GOLD AND VMS POTENTIAL Highly prospective for both orogenic gold and copper-rich VMS mineralisation associated with favourable volcanic sequences and sulphide-bearing horizons. EXPLORATION UPSIDE Multiple walk-up drill targets identified from historical drilling, artisanal workings and structural reinterpretation remain untested by deeper and systematic modern exploration. Tallering STRUCTURAL CORRIDOR EXPOSURE Covers interpreted regional-scale structural corridors considered prospective for gold and base metal mineralisation. 8 IMMEDIATE EXPLORATION AND NEXT STEPS RAPID PLANNING AND EXECUTION Catalina is rapidly assessing each tenement and reviewing all available data with the objective of progressing development and exploration programs whilst advancing heritage-related workstreams. In parallel, we are progressing toward first-pass drilling at our Cu – Au project at Beasley Creek. Now June / July July / August September/October Indicative Timeline of Activities PROGRESSING HERITAGE & ACCESS Advancing heritage, permitting and access- related activities in parallel to support efficient field execution. ADVANCING EXPLORATION PROGRAMS Progressing toward execution of prioritised exploration and drilling activities across the portfolio. TECHNICAL ASSESSMENT UNDERWAY Rapid project reviews and geological assessments currently in progress across all priority tenements. GENERATING ADDITIONAL TARGETS Systematic review and reinterpretation of historical data aimed at identifying further exploration opportunities beyond existing drill- ready targets. 9 LAKE JOHNSTON NEWLY ACQUIRED PROJECT IN ACTIVE NEIGHBOURHOOD STRATEGIC LOCATION ~265km² landholding within the emerging Lake Johnston mineral province with Forrestania Resources (ASX:FRS), TG Metals (ASX:TG6) and Charger Metals (ASX:CHR) projects and tenements adjust to holdings. ACCESS TO LAKE JOHNSTON PROCESSING HUB Positioned near Forrestania’s proposed 3.2Mtpa Lake Johnston processing hub redevelopment. MULTIPLE UNDEREXPLORED TARGETS Multiple underexplored targets supported by historical geochemistry, geophysics and regional geological interpretation. NEARBY EXPLORATION SUCCESS Xmas Gold Discovery December 2025 - 12m @ 6.55 g/t Au from 132m incl. 4m @ 16.9 g/t Au with visible coarse gold. Over 2,000m of prospective strike remains untested (Charger Metals). Medcalf Lithium Deposit Maiden Inferred Resource of 8.2Mt @ 1.0% Li₂O, announced in December 2025. Open at depth, with an Exploration Target of 3-5Mt @ 1.0-1.4% Li₂O at Medcalf West. Rio Tinto invested $6.4M before Charger elected to retain 100% ownership (Charger Metals).
