Catalina Confirms High-Grade Gold Across Expanded Mid-West WA Portfolio

Historical Gold Mineralisation Validated Across Mid-West Portfolio

Catalina Resources Limited (ASX:CTN) has completed a comprehensive review of historical exploration datasets for its recently acquired Mid-West gold project portfolio in Western Australia. The review confirms multiple significant gold mineralisation zones across key projects including Pithara, Kirkalocka, Tallering, Peak Hill, and Deflector North.

High-grade intercepts stand out at Pithara with drilling results such as 5 metres at 2.70 g/t Au including 1 metre at 8.53 g/t Au, while Kirkalocka shows mineralised zones including 28 metres at 1.09 g/t Au with a 1 metre spike of 9.69 g/t Au. Tallering's polymetallic potential is highlighted by a 1 metre intercept grading 90.3 g/t silver, 2.03% copper, and 0.89 g/t gold, complemented by rock chip samples up to 101 g/t Au.

Strategic Positioning Near Kirkalocka Processing Hub

The portfolio's strategic value is underscored by its proximity to the Kirkalocka Gold Mine, which hosts approximately 240,000 ounces of gold mineral resources, and the nearby 2 million tonnes per annum Kirkalocka processing plant. Gylden Resources' planned recommencement of this processing hub in 2026 signals a revitalised regional mining activity, enhancing the attractiveness of Catalina's holdings.

The acquisition and review follow a successful $3 million capital raising, which has bolstered Catalina’s financial capacity to advance exploration. Field activities have already commenced, with site visits and heritage assessments underway, alongside progressing land access agreements with pastoralists.

Portfolio Rich in Historical Data Enables Targeted Exploration

Catalina's approach leverages extensive historical drilling, geochemical, geological, and geophysical data compiled from previous operators including Independence Group NL, McVerde Minerals, BPM Minerals, Sandfire Resources, and Coventry Enterprises. This wealth of data allows for refined target generation and prioritisation, setting the stage for focused maiden drilling programs across the portfolio.

For example, at Pithara, historical drilling beneath transported cover revealed high-grade gold associated with quartz veining and amphibolite contacts, previously mined to produce around 9,000 ounces at 15.4 g/t Au from a shallow open pit. At Kirkalocka, mineralisation is structurally controlled and linked to fold closures and shear zones, with shallow high-grade intercepts confirming multi-lithology mineralised systems.

Next Steps and Exploration Outlook

Catalina is advancing towards maiden drilling campaigns, targeting priority zones identified through its data review. The company anticipates completing target prioritisation, field reconnaissance, and drill planning within weeks. These efforts aim to validate historical results and potentially delineate new resources within an emerging gold production district.

Executive Director Ross Cotton emphasised the rapid progress since the acquisition announcement in May 2026, highlighting the value of historical data in accelerating exploration and positioning multiple gold opportunities for drill testing.
