Catalina Resources

The Fraser North Project is located approximately 300 km east of Kalgoorlie within the Albany–Fraser Orogen.

Historical exploration programs undertaken by companies including AngloGold Ashanti and IGO Limited identified several zones of elevated silver mineralisation through aircore drilling and geophysical surveys.

Historical drilling reported several high-grade intercepts including:

4.0m @ 816.5 g/t Ag and 0.2% Co from 8m (VPA021)
1.0m @ 319 g/t Ag from 16m (17AFAC30049)
4.0m @ 48.2 g/t Ag and 0.2% Co from 14m(17AFAC30054)
4.0m @ 40.9 g/t Ag and 0.2% Co from 10m (17AFAC30068)
4.0m @ 51.1 g/t Ag and 0.2% Co from 36m (VPA103)
2.0m @ 32.1 g/t Ag and 0.2% Co from 9m (VPA075)

These results define a silver-bearing trend extending approximately 17.5 km, highlighting the potential for a larger mineralised system. 

The combination of shallow mineralisation and significant strike extent provides multiple opportunities for follow-up drilling and target generation.

The Nabberu Project is located approximately 230 km northeast of Wiluna within the Earaheedy Basin, an emerging exploration province prospective for sediment-hosted base metal and silver mineralisation.

The project lies within the Frere Formation, the same stratigraphic unit that hosts the Earaheedy Zn–Pb–Ag deposit discovered by Rumble Resources.

Historical drilling has intersected anomalous silver mineralisation including:

5.6m @ 14.8 g/t Ag from 60.6m including 1.2m @ 41.6 g/t Ag
.10m @ 9.4g/t Ag from 82.5m 

Structural deformation associated with the Stanley Fold Belt provides potential fluid pathways and traps for mineralising systems, with approximately 18 km of prospective strike remaining largely untested.

The Spinifex Silver Project comprises approximately 265 km² of tenure across two project areas, combining shallow high-grade mineralisation with large-scale basin-hosted exploration potential. The projects provide exposure to:

High-grade silver mineralisation identified along a ~17.5 km mineralised trend at Fraser North

Basin-hosted SEDEX-style mineralisation within the Earaheedy Basin at Nabberu

Underexplored mineral systems with significant strike extent and exploration potential

The Spinifex portfolio represents a compelling addition to Catalina’s exploration portfolio and introduces meaningful exposure to silver within Western Australia.

At Fraser North, historical drilling has identified very high-grade silver mineralisation along a 17.5 km trend, including results such as 4 metres at 816 g/t silver from shallow depths, highlighting the potential for a significant mineralised system that remains largely underexplored.

The Nabberu Project provides exposure to a large underexplored SEDEX-style basin-hosted silver system within the Earaheedy Basin, a region that has attracted considerable exploration interest following the discovery of the Earaheedy deposit.

Two project areas across prospective geological provinces.

Catalina has secured an option to acquire 100% of Spinifex Silver Pty Ltd, establishing a district-scale silver exploration platform across Western Australia.

The portfolio comprises approximately 265 km² of tenure across the Fraser North and Nabberu projects, providing exposure to both high-grade silver mineralisation and basin-hosted SEDEX-style systems within emerging exploration provinces.

This strategic addition broadens the Company’s commodity exposure while strengthening its exploration pipeline across multiple mineral systems.

With the option agreement in place, we will undertake a systematic technical evaluation of the Spinifex Silver portfolio. Initial work programs are expected to focus on:

Compilation and reinterpretation of historical geological, geophysical and drilling datasets

Integration of historical data into our GIS and exploration targeting frameworks

Field validation of previously identified mineralised structures and targets

Geochemical sampling and structural mapping across priority areas

Development of follow-up drilling programs to test priority targets
