Drilling Mobilisation Signals New Phase for Catalina Resources

Catalina Resources Limited (ASX – CTN) is gearing up to commence a substantial Phase 1 drilling program at its Evanston and Yerilgee gold projects in the Central Yilgarn region. Scheduled to start on 1 December 2025, the campaign will deploy approximately 7,500 metres of reverse-circulation (RC) and aircore (AC) drilling to probe priority targets identified through previous exploration.

The company has completed critical preparatory steps including site establishment, earthworks, and access preparation, ensuring the program can proceed without delay. Heritage assessments have been finalised, with the drill plan carefully designed to comply with all regulatory and cultural requirements, reflecting Catalina’s commitment to responsible exploration.

Strategic Targeting of High-Potential Zones

The Phase 1 program focuses on testing key structural corridors and geochemical anomalies that have shown promising mineralisation in earlier drilling campaigns. At Evanston, prospects such as Leghorn, Viper South, and T1B will be explored, while at Yerilgee, drilling will target areas including T8, Chicken Little, and Snowflake. Historical results from these areas have included encouraging gold grades near surface, underscoring the potential for resource expansion.

McKay Drilling, a respected Australian contractor, has been engaged to deliver the drilling services, with mobilisation already underway. This partnership is expected to facilitate efficient and high-quality data collection, critical for advancing the projects’ development.

Looking Ahead – Data and Discovery

As drilling progresses, samples will be dispatched progressively to laboratories for assay analysis. The results will be pivotal in confirming the extent and continuity of mineralisation, potentially reshaping Catalina’s resource base and informing future phases of exploration or development.

Executive Director Ross Cotton highlighted the significance of this phase, noting that it builds on a robust foundation of prior results and aligns multiple datasets to sharpen the company’s understanding of the mineral systems. The coming weeks will be closely watched by investors and analysts eager to see how these efforts translate into tangible resource growth.

Bottom Line?

Catalina’s drilling launch marks a critical step toward unlocking the full potential of its Central Yilgarn gold assets.

Questions in the middle?

  • Will assay results confirm the lateral and vertical continuity of mineralisation?
  • How might Phase 1 outcomes influence Catalina’s resource estimates and valuation?
  • What are the prospects for advancing to Phase 2 drilling or development following these results?
