New Fault Discovery at Mulgabbie North Raises Stakes for OzAurum’s Gold Ambitions
OzAurum Resources confirms consistent high-grade gold mineralisation at its New Cross Fault discovery within the Mulgabbie North Gold Project, highlighting promising drill results and a new structural target that could significantly enhance the project’s resource base.
- Multiple high-grade gold intersections from recent 1m aircore drilling
- New Cross Fault discovery located 1.3km south of previous drilling
- Gold mineralisation open at depth and along strike within Relief Shear corridor
- Additional 32-hole aircore drilling completed with assays pending
- New north-south fault identified, potentially key to mineralisation controls
Discovery Highlights and Drill Results
OzAurum Resources Ltd (ASX: OZM) has announced compelling results from its latest aircore (AC) drilling campaign at the Mulgabbie North Gold Project in Western Australia. The 1m sample assays have confirmed consistent high-grade gold mineralisation at the newly identified New Cross Fault target, situated approximately 1.3 kilometres south of the company’s previous drilling activities.
Noteworthy intercepts include 16m at 3.21 g/t Au (including 4m at 10.22 g/t Au) and 9m at 6.76 g/t Au (including 4m at 13.54 g/t Au), among others. These results validate the exploration model that positions the New Cross Fault within the prospective Relief Shear corridor, a structural setting known for hosting significant gold deposits.
Geological Significance and Structural Insights
The discovery of a new north-south fault at the Cross Fault area adds a fresh dimension to the project’s geological framework. This fault orientation is analogous to structures controlling major gold deposits in the Eastern Goldfields, such as Carosue Dam. The mineralisation is hosted predominantly in sandstone with extensive quartz veining, a hallmark of large-scale gold systems in the region.
The presence of oxidised pyrite and arsenopyrite mineralisation observed in drill chips suggests significant potential at depth, with several drill holes ending in mineralisation, indicating the system remains open for further expansion.
Ongoing Exploration and Future Plans
Following the initial 52-hole AC program, OzAurum has completed an additional 32-hole AC drilling campaign targeting fresh rock south of the New Cross Fault, with assay results expected imminently. The company plans to advance to reverse circulation (RC) drilling to test the high-grade zones at depth once rig availability and targeting are finalised.
With an existing resource of 260,000 ounces at Mulgabbie North, these new findings could materially enhance the project’s scale and economic potential. CEO Andrew Pumphrey expressed optimism about the discovery’s implications, emphasizing the company’s commitment to aggressive exploration and resource growth in 2025.
Context Within Regional Gold Province
The Mulgabbie North Project lies within a prolific gold province near Kalgoorlie, adjacent to the Carosue Dam basin, which hosts multi-million-ounce deposits. The structural and lithological similarities observed at the New Cross Fault position OzAurum’s project as a compelling exploration target with potential for significant resource development.
Historical drilling in the area, including limited work by Gutnick Resources in the late 1990s, intersected mineralisation but was never followed up, underscoring the value of OzAurum’s renewed focus and modern exploration techniques.
Bottom Line?
As OzAurum advances its drilling programs, the New Cross Fault discovery could redefine Mulgabbie North’s resource trajectory and attract renewed market attention.
Questions in the middle?
- How will the pending assay results from the additional 32-hole AC program influence the resource model?
- What are the timelines and scale for the planned RC drilling to test mineralisation at depth?
- Could the newly identified north-south fault unlock further exploration targets beyond the current footprint?
