Catalina Resources is an Australian diversified mineral exploration and mine development company.

Catalina Resources (“Catalina” or “the Company”) is pleased to provide an update on exploration at its Oak Hill Project (Exploration Licence 9346) in the Southern Lachlan Fold Belt, NSW. Highlights • The tenement covers the southwestern extension of a mineralised trend that contains two gold resources with a combined JORC Mineral Resource of 154koz Au. • Catalina has completed in-fill soil and rock chip sampling and geological mapping of the target area along strike of the structure hosting the two resources. • Assays up to 1.4 g/t Au, 28 g/t Ag, 0.44% Pb and 1.27% As have been received from rock chips. • The soil and rock chip assays outline a robust southwest orientated geochemical anomaly exceeding 600m in strike length. • Aeromagnetic images provide strong support of an underlying structure coincident with the geochemical anomaly. The tenement is located 20km northwest of the town of Albury in southern New South Wales as shown in Figure 1. The Oak Hill project covers an area of approximately 25 km2. EL9346 covers Ordovician metasediments and phyllites that are intruded to the north and east by the late Silurian-Early Devonian I-type Jindera Granite, responsible for several gold deposits in the northern Albury area¹. Catalina’s EL9346 abuts EL7544 on its eastern side. Within EL7544 the Stoney Park and Elm Park gold prospects, discovered in 2015 by Minerals Aust Pty Ltd², have a combined JORC Mineral Resource of 154koz Au 5: Stoney Park - 0.86Mt at 2.75 g/t Au and 2.32 g/t Ag (72,000oz Au and 61,000oz Ag respectively). Elm Park - 2.31Mt at 1.43 g/t Au and 1.01 g/t Ag, (82,000oz Au and 63,000oz Ag respectively). During 2015, sixty-six reverse circulation (RC) holes were drilled on the Elm Park and Stoney Park properties in EL7544 ³. The drilling at Stoney Park and Elm Park identified a zone of gold mineralisation in narrow quartz veins in Ordovician metasediments extending over a strike length of at least 2.5 km. Gold mineralisation at Elm Park and Stoney Park is hosted by a northeast trending fault that is evident in aeromagnetic images. Anomalous historical geochemical soil contours overlie the structure as illustrated in Figure 3. Catalina Resources Limited ACN: 130 618 683 W: www.catalinaresources.com.au ASX RELEASE. Page 2 of 16 Figure 1. Regional location of the Oak Hill prospect. Known mineral occurrences within EL7544 include the Stoney Park workings and several small, abandoned gold mines. Gold grades in quartz veins are variable. The gold grade of individual veins, which are less than 0.5m in width can be very high. A vertical hole drilled down a quartz vein in the Stoney Park East zone intersected 8m at 13 g/t Au including 2m at 39 g/t Au. The width of mineralised intercepts >= 1 g/t Au in angled holes ranges from 1m to 9m. The mineralised veins dip steeply (80-85⁰) to the east and generally appear to be bedding-parallel. ASX RELEASE.

Also shown is the location of Figure 3. Exploration by Catalina Resources. In April 2023, Catalina collected 15 rock chip samples and 65 soil samples during a regional mapping exercise of the tenement, EL9346. Best rock chip assays are provided in Table 1 and their locations are illustrated in Figure 3. The rocks are anomalous in a range of elements including Au, As, Ag, Bi, Cu, Pb, Sb and Mo. ASX RELEASE.

Anomalous rock chip assays from EL9346. Figure 3 is a summary of Catalina’s soil and rock chip sampling geochemistry overlain on the RTP aeromagnetic image. Outcropping rocks in the area are rare and the undulating terrain is covered by extensive grasslands suitable for cattle grazing. Au and As soil contours together with rock chip assay data suggest anomalous geochemistry is present over 600m within EL9346 as illustrated in Figure 3 (green dotted line). Hosting the anomalous geochemistry is a distinctive and separate NE-SW orientated elliptical aeromagnetic feature. It lends support for an underlying structure coincident with the soil and rock chip geochemical anomaly. This feature is in an offset position to the trend of the Stoney Park historical drilling and its magnetic susceptibility is suggestive of a different protolith to that seen in the historical resources. Possible protolith alternatives include a highly altered granitic intrusive or porphyry style source rocks. Additionally, an old gold working (for its location, see callout ‘Rock chip assays from old gold working’ in Figure 3) revealed rocks with a strongly recrystallized and silicified igneous texture, a rock type unlike that described for the Elm and Stoney Park deposits. Petrography⁴ suggests these rocks are indicative of an igneous petrogenesis with late stage silicification of feldspars by hydrothermal activity, as evidenced by banding in an alteration overprint and common clay altered fine veins and groundmass containing sericite and muscovite. Common strain is recognised through quartz populations and suggests a high strain regime / shear zone. ASX RELEASE. Page 5 of 16 Figure 3. Summary diagram of the rock and soil Au and As geochemistry within EL9346. The trend of anomalous geochemistry is shown by the green dotted line. Background image is the Reduced to Pole (RTP) aero magnetics. A feature of these altered rocks is the presence of abundant euhedral arsenopyrite and trace scorodite as illustrated in Figures 4 and 5. Other sulphides include pyrite and galena. These arsenopyrite rich rocks, also containing anomalous gold, may be the source of the anomalous soil geochemistry seen in Figure 3 and testing by RC drilling for economic gold mineralization is a high priority.

Page 7 of 16 A listing of all the soil and rock chip samples collected, their locations and their geochemistry is shown in Appendices 1 and 2 respectively of this announcement. The methods used to collect the soil and rock chip samples is described in JORC Code 2012 Edition-Table 1, attached to this announcement (pages 11-16). Conclusions and Next Steps. Catalina’s tenement (EL9346) covers the southwestern extension of a mineralised structure that contains two gold resources with a combined JORC Mineral Resource of 154koz Au. Gold mineralization occurs over a distance of 4,000m. The numerous sub parallel narrow quartz veins occur in a quite narrow corridor (20m) in the Stoney Park East area but over a significantly wider corridor (up to 150m) in the Elm Park area (Figure 2). These features suggest the hosting structure is a significant crustal fracture acting as a conduit for auriferous fluids to permeate. Gold precipitation then occurred at local areas of dilation within the structure. Catalina has identified significant Au and As surface geochemistry that confirms mineralization is present at the south western extension of this significant structure within EL9346. The geochemical anomaly occurs in a structurally complex area near the intersection of 2 faults (Figure 3) and is off trend from the Elm Park - Stoney Park mineralization trend. Catalina will compile available data and do exploration studies to enable planning of RC drilling to evaluate the geochemical targets outlined in this announcement. It is expected that these studies and drill planning will be completed in the coming quarter July to September 2023 with the aim of embarking upon the drilling in the following quarter.
