Highlights
- DHEM surveys and diamond drilling at Breakaway Dam have identified copper-rich mineralisation consistent with a VMS system.
- Every drill hole hit sulphide-rich horizons with favourable DHEM responses.
- Zinc and copper mineralisation has been verified over ~700 metres of strike within the central project area
- Several high-conductance EM plates are yet to be tested, offering high-priority targets.
- Future assessments will include fire assay testing to determine the project’s gold potential.
Catalina Resources Limited (ASX:CTN) has reported encouraging results from recent diamond drilling and downhole electromagnetic (DHEM) surveys at the Breakaway Dam Copper Project, undertaken by Forrestania Resources Limited. The work has confirmed copper-rich mineralisation consistent with a Volcanogenic Massive Sulphide (VMS) system.
The drilling intersected thick, sulphide-rich horizons in every hole, supported by positive DHEM responses. These findings confirm that the mineralisation system is both continuous and scalable, establishing the technical foundation for systematic exploration once the transaction concludes.
Drilling Results Over a 700-Metres Strike
Exploration work has confirmed copper and zinc mineralization across a 700-metre strike length in the project’s central area. Notable intercepts include-
- 2 m @ 0.48% Cu (estimated true width 8.7 m), including higher-grade intervals of 0.95 m @ 1.18% Cu and 1.7 m @ 1.05% Cu (BDCDD2501)
- 47 m @ 1.97% Cu and 0.24% Zn (estimated true width 1.4 m) (BDCDD2502)
- 2 m @ 0.32% Cu and 0.29% Zn (estimated true width 4.1 m) (BDCDD2504)
These results build on earlier exploration that identified electromagnetic conductors beneath surface copper expressions.
DHEM Surveys Identify Targets for Future Exploration
Downhole EM surveys identified multiple conductors in each drill hole, with interpretation suggesting that some holes intersected the margins of main sulphide accumulations. The results indicate that further sulphide development might occur nearby. Numerous high-conductance EM plates are currently untested, serving as priority targets for the next phase of drilling.
District-Scale Exploration and Gold Potential
The project features a broader 16-kilometre stratigraphic trend extending beyond the central mineralised area. Large sections of this trend remain untested, highlighting district-scale exploration potential.
In addition to base metals, the company believes that the project also has gold potential. Fire assay analysis of existing drill pulps is planned to assess the presence and potential significance of gold mineralisation within the system.
Next Steps
Following finalisation of the proposed transaction, the company plans to complete and report gold assay results, drill test untested EM plates, undertake systematic RC drilling within the central corridor, and advance first-pass drilling across regional targets.
