Catalina Resources Ltd (ASX: CTN) (‘Catalina’ or the ‘Company’) is pleased to provide an Activities Report for work undertaken during the June 2025 quarter. Exploration During the quarter, the Company advanced exploration activities across its Central Yilgarn and Laverton Projects, both located within prospective and underexplored greenstone belts in Western Australia (Figure1). Central Yilgarn Project (Yerilgee & Evanston Belts) The Company completed a technical review of historical datasets across the Yerilgee and Evanston greenstone belts, acquired in January 2025 from the wholly owned subsidiary of Dreadnought Resources Limited (ASX: DRE), Dreadnought Exploration Pty Ltd. The review generated several walk-up RC drill targets. An initial RC drilling program is scheduled to commence in H2 2025.

The belt is host to three main gold targets zones: T6, T8 and T11 (Figure 2). Figure 2 – Regional geological interpretation of the Yerilgee Greenstone Belt. It hosts three primary camp-scale gold targets: T6, T8, and T11. The T6 Gold Camp contains the Chicken Little, Snowflake and Megatron drill targets Catalina Resources Limited ACN 130 618 683 ASX: CTN T: 61 8 6165 8858 E: info@catalinaresources.com.au A : 2/7 Havelock Street West Perth WA 6005 Page 3 of 15 catalinaresources.com.au • T6 Gold Camp (Yerilgee): Follow-up RC drilling at Chicken Little intersected significant gold and silver mineralisation (Figure 3), including o CYRC012: 17m @ 4.1g/t Au and 28g/t Ag from 53m, including 4m @ 14.9g/t Au and 72.2 g/t Ag from 54m; and o CYRC013: 7m @ 0.2 g/t Au, 56 g/t Ag from 82m.

The anomaly is associated with a significant domal structure, interpreted as a potential granitic intrusion. Two additional high-tenor gold-in-soil anomalies remain untested.

It hosts widespread quartz veining, including large veins up to 40m thick that extend for several hundred metres. The belt comprises basalts, ultramafics, sediments, banded iron formations, and felsic intrusions. Two main gold targets areas, T1 and T2 were identified, both with confirmed mineralisation and high-grade intercepts that remain largely untested. • T1 Gold Camp: The Viper Prospect (Figure 6 – 7) within T1 returned: o 15m @ 1.5g/t Au from 12m, including 3m @ 6.7g/t Au in aircore hole BARC0136; and o 33m @ 0.3g/t Au, including 3m @ 0.9g/t Au in aircore hole BARAC0945 Only 3 RC holes have been drilled at the Viper Prospect. Notable intercepts remain open and represent promising drill targets for further exploration by the Company.

Showing two primary camp-scale gold targets T1 and T2. • T2 Gold Camp: At T2, Leghorn (Figure 8) and Erk continue to show potential for both Au and Cu-REE mineralisation o Leghorn: ▪ 48m @ 0.6g/t Au from 27m, including 21m @ 1.3 g/t Au in hole BARRC07 ▪ 34m @ 0.5 g/t Au from 32m, including 1m @ 2.88 g/t Au in BARRDD02 ▪ 7m @ 0.79% Cu, including 2m of 2.1% Cu, 535 ppb Au, 4 ppm Mo and 17.4 g/t Ag in RC hole BARRC01 These results align with a defined structural trend supported by anomalous soil geochemistry for Au, Ag, Mo and Cu. o Erk: A 3km gold-in-soil anomaly over sheared granite and calc-silicates returned gold in all first-pass drill lines. The area remains open and may host skarn-style or shear zone related Au-Cu mineralisation.

Laverton Project Laverton Gold Project Aircore drilling in 2024 targeted the Barnicoat Shear Zone, a major mineralised structure in the Eastern Goldfields. A standout result was 28m @ 1.09g/t Au from 57m in hole LVAC049, including 1m @ 9.69g/t Au, indicating a potential bedrock gold source beneath saprolitic clays. Nearby holes also showed signs of veining and alteration, supporting a hydrothermal system model.

The REE assays contain elevated neodymium and praseodymium (NdPr) values of up to 0.3%. The NdPr to Total Rare Earth Oxides (TREO) ratio is comparable to the nearby Mt Weld deposit, suggesting possible carbonatite-related mineralisation despite deep weathering and limited drill spacing.
