OzAurum Resources has confirmed a substantial 400-metre strike of high-grade gold mineralisation at its Cross Fault discovery within the Mulgabbie North Gold Project, signalling promising expansion potential. Further drilling and resource estimation plans are underway as the mineralisation remains open at depth.
- 400m strike length of high-grade gold confirmed at Cross Fault
- Multiple significant gold intercepts in fresh rock from recent RC drilling
- Mineralisation remains open at depth with sulphide and quartz vein presence
- Cross Fault located near existing 260,000 oz Mulgabbie North resource
- Drilling planned to support maiden mineral resource estimate and expand exploration
Expanding the Gold Footprint at Cross Fault
OzAurum Resources Ltd (ASX, OZM) has reported encouraging results from its latest reverse circulation (RC) drilling campaign at the Cross Fault zone, part of its Mulgabbie North Gold Project in Western Australia's Eastern Goldfields. The company has confirmed a 400-metre strike of high-grade gold mineralisation hosted in fresh rock, significantly extending the known footprint of this emerging discovery.
The drilling program, comprising 17 holes totaling 1,858 metres, delivered multiple notable intercepts including 10 metres at 2.18 grams per tonne (g/t) gold and 21 metres at 1.22 g/t gold, with higher-grade intervals reaching above 11 g/t. These results validate the presence of robust mineralisation within brittle sandstone host rocks, a geological setting analogous to the nearby Carosue Dam deposits operated by Northern Star Limited.
Geological Context and Strategic Location
Cross Fault lies just 1.3 kilometres south of OzAurum’s existing Mulgabbie North resource, which currently holds an estimated 260,000 ounces of gold. The mineralisation is associated with the Relief Shear, a major structural feature known to host significant gold deposits in the region. The presence of sulphide minerals such as pyrite and arsenopyrite alongside quartz veining suggests a classic mesothermal gold system with potential for further extensions both along strike and at depth.
CEO Andrew Pumphrey highlighted the significance of the discovery, noting the mineralisation style and host rock similarities to Carosue Dam, which bodes well for the scale potential of Cross Fault. The company is planning infill and extensional drilling on a tighter grid to enable a maiden mineral resource estimate, aiming to convert this promising exploration into a defined asset.
Broader Exploration Momentum
Beyond Cross Fault, OzAurum is advancing exploration at Heysen’s Find, another high-grade gold target within its tenement portfolio. Following heritage and archaeological surveys, the company has submitted a Programme of Work for drilling approval, anticipating to commence RC drilling shortly. This reflects a broader strategy to unlock multiple gold systems across its Eastern Goldfields projects.
While the Golden Goose target returned modest results in recent drilling, the presence of sulphide mineralisation and quartz veining indicates ongoing potential that warrants further structural and geological assessment.
Looking Ahead
OzAurum’s recent drilling success at Cross Fault marks a pivotal step in expanding its gold resource base. The confirmation of high-grade mineralisation over a significant strike length, combined with geological analogues to major regional deposits, positions the company well for future resource growth. However, the mineralisation remains open-ended, and the upcoming drilling campaigns will be critical in defining the scale and economic viability of the discovery.
Bottom Line?
OzAurum’s Cross Fault discovery is shaping up as a key growth driver, but the next drilling phase will be decisive in unlocking its full potential.
Questions in the middle?
- How extensive is the mineralisation at depth beyond the current 400m strike?
- What timeline and criteria will OzAurum apply to deliver a maiden mineral resource estimate?
- How will regulatory approvals impact the planned drilling at Heysen’s Find?
