Cobra Resources has reported encouraging early-stage results from its Manna Hill copper project in South Australia, pointing to the potential presence of a larger porphyry system beyond the previously identified shallow skarn mineralisation. The company adjusted its drilling programme from a planned 1,800 metres to 1,500 metres, reallocating effort toward deeper and more promising drill holes rather than continuing at the Black Rock target, where initial results suggested distance from the main mineralising source.

A key technical development is the transition in copper mineralisation from chalcopyrite to bornite observed in diamond drilling. This shift is significant because bornite contains a higher copper content and is typically associated with the potassic core of porphyry systems, suggesting proximity to a larger and potentially more economically viable mineral source. Supporting this interpretation, drilling has extended sulphide mineralisation continuity to depths of around 300 metres, beneath earlier shallow reverse circulation intercepts that already showed notable copper and gold grades.

In addition, a step-out hole drilled south of the known skarn unexpectedly intersected shallow copper oxide mineralisation outside the previously defined footprint, indicating a new and untested extension zone. Cobra also identified anhydrite breccia, a feature often linked to fluid pathways in large porphyry systems, further strengthening the geological model.

While these findings are based on visual core observations and remain subject to laboratory assay confirmation expected around August, they collectively suggest growing scale potential at Manna Hill. The company is planning further drilling in September to test the extent of the southern zone and refine its geological understanding. Alongside this, Cobra continues to advance its Boland rare earth project, providing a parallel development pathway.
