Cross Fault Drilling Yields 10m @ 1.80 g/t Au and 1m @ 6.12 g/t Au at Mulgabbie North
OzAurum Resources has confirmed significant high-grade gold mineralisation at the newly discovered Cross Fault within its Mulgabbie North Gold Project, with ongoing drilling set to further unlock the zone’s potential.
- High-grade gold confirmed over 400m strike at Cross Fault
- Multiple strong RC drill intersections including 10m @ 1.80 g/t Au and 1m @ 6.12 g/t Au
- Diamond drilling underway to understand geology and structural controls
- 2,500m infill and extensional drilling planned to expand resource confidence
- Cross Fault discovery enhances Mulgabbie North’s existing 260,000 oz gold resource
Significant New Discovery at Mulgabbie North
OzAurum Resources (ASX: OZM) has announced compelling results from its recent reverse circulation (RC) drilling program at the Mulgabbie North Gold Project in Western Australia. The company’s exploration efforts have confirmed significant high-grade gold mineralisation along a newly identified structural feature dubbed the Cross Fault. This discovery extends over a 400-metre strike length and includes multiple high-grade intersections that validate the potential of this previously untested zone.
Drilling Highlights and Mineralisation Details
The RC drilling program delivered notable intercepts such as 10 metres at 1.80 grams per tonne (g/t) gold from 127 metres, including a 1-metre high-grade zone at 3.91 g/t Au, and other strong results like 8 metres at 1.81 g/t Au and 7 metres at 2.17 g/t Au. Several holes ended in mineralisation, indicating the system remains open at depth. The presence of sulphides such as pyrite and arsenopyrite in fresh rock further supports the prospectivity of the Cross Fault as a significant gold-bearing structure.
Strategic Diamond Drilling and Future Plans
Complementing the RC program, OzAurum has completed two diamond drill holes aimed at better understanding the structural geology and lithological controls of mineralisation at the Cross Fault. These insights are critical for refining the exploration model and guiding future drilling. The company is planning an extensive 2,500-metre aircore (AC) and RC drilling campaign focused on infill and step-out drilling to the south, targeting extensions of the mineralised system and improving resource confidence.
Broader Project Context and Resource Implications
The Cross Fault discovery significantly enhances the prospectivity of the Mulgabbie North Project, which already hosts a reported mineral resource of approximately 260,000 ounces of gold at a 0.70 g/t cutoff. The new mineralised zone lies within the Relief Shear, a major structural corridor known for hosting gold deposits in the region. OzAurum’s CEO Andrew Pumphrey highlighted the importance of this discovery in expanding the scale and confidence of the gold system, emphasizing the company’s commitment to aggressive exploration and resource growth.
Operational and Technical Considerations
In addition to exploration drilling, OzAurum has undertaken water supply drilling to support future operational needs. Assay turnaround times remain lengthy due to high regional exploration activity, with results expected over the coming weeks. The company’s methodical approach, combining RC and diamond drilling with detailed geological mapping, positions it well to delineate a robust resource base and advance the project toward development.
Bottom Line?
OzAurum’s Cross Fault discovery at Mulgabbie North marks a pivotal step in unlocking a potentially substantial gold system, with upcoming drilling poised to define its true scale.
Questions in the middle?
- How will upcoming assay results from the 2,500m drilling program impact resource estimates?
- What structural controls are driving the high-grade mineralisation at the Cross Fault?
- Could the Cross Fault discovery lead to a significant resource upgrade or new mining targets?
