Sipa Identifies Multiple Structures Within 5km Gold Anomaly Near 1.6Moz Deposit
Sipa Resources has integrated a detailed historical heli-magnetic survey with regional data at its Tunkillia North gold project, revealing multiple structural targets within a large gold anomaly near Barton Gold’s 1.6 million-ounce deposit. The company is advancing environmental and heritage approvals ahead of planned drilling programs.
- High-resolution heli-magnetic survey merged with regional magnetics
- Multiple subsidiary structures identified within 5km x 5km gold anomaly
- Tunkillia North project located near Barton Gold’s 1.6Moz deposit
- Environmental and heritage approvals progressing for drilling
- Further geophysical data reprocessing underway to refine targets
Enhanced Magnetic Data Reveals New Structural Complexity
Sipa Resources Limited (ASX: SRI) has significantly upgraded the geological understanding of its Tunkillia North gold project in South Australia by integrating a high-quality historical heli-magnetic survey with existing regional magnetic datasets. This fusion of data has unveiled multiple subsidiary, en-echelon structures associated with the Yerda Shear Zone, underlying a large-scale 5km by 5km gold anomaly defined by calcrete geochemistry.
The detailed heli-magnetic survey, originally conducted in the late 1990s by Mount Isa Mining Exploration, offers line spacings of 50 to 70 metres, much finer than the 200-metre spacing of more recent regional surveys. This higher resolution has allowed Sipa to identify structural complexities that were previously obscured, enhancing the precision of drill targeting within the anomaly.
Strategic Location Near a Major Gold Deposit
The Tunkillia North project lies just 10 kilometres north of Barton Gold’s 1.6 million-ounce Tunkillia gold deposit, situated at a geological triple junction where the fertile Yarlbrinda Shear Zone intersects with the east-west trending Yerda Shear Zone. This structural setting is known to host significant gold mineralisation, adding weight to the prospectivity of Sipa’s anomaly.
Managing Director Andrew Muir highlighted the importance of the newly identified subsidiary structures, stating they confirm the potential of the large calcrete gold anomaly and will be the focus of upcoming drilling campaigns. The company is also reviewing additional historical geophysical and drilling datasets to further refine its geological models.
Advancing Toward Drilling with Approvals in Place
Sipa is progressing environmental and heritage approvals, including the submission of a Program for Environment Protection and Rehabilitation (PEPR), which covers reverse circulation and aircore drilling across multiple prospects including Tunkillia North, Sheoak, Arcoordaby, and Bimba. Heritage surveys are scheduled to commence shortly, reflecting the company’s commitment to responsible exploration practices.
The company expects to announce the timing of its initial drilling programs soon, marking a critical next step in testing the gold potential of these newly acquired South Australian projects. The integration of historical data and modern processing techniques positions Sipa well to unlock value from these underexplored targets.
Looking Ahead
With a robust pipeline of exploration activities and a strategic position near a major gold deposit, Sipa’s Tunkillia North project is poised to attract investor attention as drilling approaches. The company’s methodical approach to data integration and approvals underscores a disciplined exploration strategy in a competitive gold province.
Bottom Line?
Sipa’s refined targeting and imminent drilling at Tunkillia North could soon translate geological promise into tangible results.
Questions in the middle?
- When exactly will Sipa commence drilling at Tunkillia North and other prospects?
- How will the newly identified subsidiary structures influence drill hole placement and depth?
- What are the potential implications if early drilling confirms significant gold mineralisation?
