Cosmo Metals Unveils +8km Antimony Gully Trend with High-Grade Assays at Bingara
Cosmo Metals has identified a new +8km Antimony Gully Trend at its Bingara Project in NSW, confirming significant antimony prospectivity with rock chip samples assaying up to 5.75% Sb. This discovery positions the company strongly in a region known for world-class antimony-gold deposits.
- New +8km Antimony Gully Trend defined by LiDAR data
- Historic McManus mine samples up to 5.75% antimony and 0.14 g/t gold
- Trend aligns with regional Gineroi fault zone and Peel Fault system
- Geological similarity to Red Mountain and Larvotto Resources projects
- Planned follow-up includes soil sampling, mapping, and drill target prioritization
Exploration Breakthrough at Bingara
Cosmo Metals Ltd (ASX – CMO) has announced a significant advancement in its exploration efforts at the Bingara Project, located in the New England Orogen of New South Wales. Leveraging high-resolution LiDAR data, the company has delineated a new +8 kilometre long corridor dubbed the Antimony Gully Trend. This trend is marked by clusters of historic antimony mines and workings, notably along the regional-scale Gineroi fault zone, a splay of the major Peel Fault system.
High-Grade Rock Chip Results at McManus
Reconnaissance rock chip sampling at the historic McManus mine, situated on the Antimony Gully Trend, has returned assays of up to 5.75% antimony (Sb) and 0.14 grams per tonne (g/t) gold (Au). Visible antimony sulphide mineralisation was confirmed in vein breccias on mine dumps, underscoring the potential for significant mineralisation. Importantly, this area has seen no modern exploration, highlighting the opportunity for new discoveries.
Strategic Geological Context
The Antimony Gully Trend lies within a geological setting analogous to other notable antimony-gold projects in the region, including Red Mountain Mining’s Armidale Antimony Project to the south and Larvotto Resources’ Hillgrove Antimony-Gold Deposit. The trend’s alignment with the Gineroi fault zone and proximity to the Peel Fault system suggest district-scale controls on mineralisation, enhancing the prospectivity of Cosmo’s tenure.
Next Steps in Exploration
Cosmo Metals plans to expand its exploration program with further reconnaissance sampling along the Antimony Gully Trend, followed by detailed soil geochemical surveys and geological mapping. These activities aim to refine and prioritise drill targets to test the depth and extent of mineralisation, particularly given indications that the McManus workings may represent the upper levels of a mineralised system with potential for higher grades at depth.
Broader Project Significance
This discovery reinforces the multi-commodity potential of the Bingara Project, which also hosts targets for gold and copper. Cosmo’s Managing Director, Ian Prentice, emphasised the strategic importance of antimony as a critical mineral and the company’s strong position to advance exploration in a region recognised by the NSW Mines Department for its high antimony-gold prospectivity.
Bottom Line?
Cosmo Metals’ Antimony Gully Trend discovery marks a pivotal step in unlocking critical mineral resources at Bingara, with upcoming drilling poised to test its true potential.
Questions in the middle?
- What are the expected timelines and scale for drilling programs to test the Antimony Gully Trend?
- How might Cosmo Metals leverage this discovery to attract strategic partnerships or funding?
- What are the implications of antimony’s critical mineral status on project development and market interest?
