Catalina Resources Limited has taken a significant step forward in its exploration plans with the commencement of its Phase 1 reverse circulation (RC) drilling program at the Evanston Gold Project in Western Australia. The campaign is focused on systematically testing high-priority gold targets within the Evanston corridor, aiming to build a clearer understanding of the project’s mineralisation potential.
Phase 1 RC Drilling Program Underway
Catalina Resources has launched its Phase 1 reverse circulation (RC) drilling program at the Evanston Gold Project in Western Australia, marking an important advancement in its Central Yilgarn exploration strategy. The campaign targets several high-priority zones along the Evanston corridor, including Leghorn, Viper South, and T1B.
Scope of the Drilling Campaign
The Phase 1 program consists of approximately 36 RC holes totalling around 5,670 metres, with completion expected by late December 2025. The drilling is designed to evaluate key structural and geochemical targets defined through historic work and recent geological modelling. Previous drilling in the area has delivered promising results, such as 48 metres at 0.67 g/t gold and 33 metres at 0.3 g/t gold from surface.
Sampling and Assay Progress
Continuous sampling is being carried out from surface to end-of-hole, ensuring comprehensive analysis across each drill section. The initial batch of samples has already been dispatched for PhotonAssay testing at ALS Kalgoorlie, providing rapid and reliable insights into gold mineralisation.
Next Steps: Mobilisation to Yerilgee Project
Upon completion of the Evanston drilling, Catalina will move its resources to the nearby Yerilgee Project. Exploration efforts there will focus on testing gold-in-soil anomalies and banded iron formation hosted mineralisation. Previous drilling at Yerilgee has yielded strong results, including 17 metres at 4.1 g/t gold, highlighting the project’s potential.
Company Outlook and Strategy
Executive Director Ross Cotton emphasised that the Phase 1 program represents a critical test of Catalina’s highest-priority targets. The results will assist in refining the geological model for Evanston and evaluating the scale of the mineralised system. Cotton reiterated the company’s commitment to disciplined, data-driven exploration aimed at creating long-term value for shareholders.
Advancing Exploration in the Central Yilgarn
The launch of Phase 1 drilling at Evanston underscores Catalina Resources’ strategic push to advance its exploration portfolio. With systematic testing and geological refinement underway, the company continues to position itself for potential new gold discoveries across the Central Yilgarn region.
