Cross Fault Expansion Raises Stakes for OzAurum’s Mulgabbie North Gold Project

Expanding the Cross Fault Discovery

OzAurum Resources (ASX: OZM) has announced a promising expansion of gold mineralisation at its Mulgabbie North Gold Project in Western Australia. The latest diamond and air-core drilling results at the Cross Fault target have extended the known mineralised strike length by approximately 600 metres to the south, significantly enhancing the scale and prospectivity of this emerging discovery.

The diamond drilling program, comprising two holes spaced 70 metres apart, confirmed the presence of two parallel mineralised zones. These include a sheeted vein array and breccia-style mineralisation, with visible gold observed in quartz veins, an encouraging validation of OzAurum's geological model. Notably, one hole returned a 25-metre intercept grading 1.24 grams per tonne gold, including high-grade one-metre intervals exceeding 5 grams per tonne.

Air-Core Drilling Extends Mineralisation

Complementing the diamond drilling, an 82-hole air-core program totaling 2,290 metres has confirmed the southern extension of gold mineralisation beyond the Cross Fault. Several shallow gold intercepts were recorded, including 4 metres at 1.03 grams per tonne from 24 metres depth. These results highlight the potential for near-surface mineralisation and provide immediate targets for follow-up reverse circulation (RC) drilling.

Importantly, the air-core drilling delineated new RC drill targets adjacent to outcropping porphyry, a geological feature often associated with significant gold deposits. The identification of fault offsets and structural complexities further refines the exploration model and guides future drilling campaigns.

Geological Insights and Next Steps

OzAurum’s Managing Director, Andrew Pumphrey, emphasized the significance of confirming two distinct gold mineralisation styles and the presence of visible gold. He noted that the oxidised sheeted pyrite vein array observed is a strong validation of their geological interpretation. The company plans to advance the next phase of exploration with broader RC drilling designed to test these newly defined high-priority targets.

The Cross Fault target lies within the broader Mulgabbie North Project, which hosts an existing mineral resource of approximately 260,000 ounces of gold at a 0.3 g/t cutoff. The recent drilling results not only extend the known mineralisation but also enhance the overall prospectivity of the project, which is strategically located near established gold mining operations in the Eastern Goldfields region.

OzAurum continues to engage structural geology expertise to refine fault interpretations and improve targeting accuracy. The company is also managing assay turnaround times amid a busy regional exploration environment, aiming to maintain momentum in its exploration activities.
