West Cobar Metals Unveils New High-Grade Targets at Bulla Park
West Cobar Metals has identified promising new copper, antimony, and silver targets at its Bulla Park project, supported by advanced geological and geophysical analysis. The company plans priority drilling to explore these zones and potentially expand its resource base.
- New high-grade copper-antimony-silver targets identified through mapping and geophysics
- Gravity and chargeability surveys highlight untested thick mineralisation zones near a major fault
- Bulla Park hosts an Inferred Mineral Resource of 20 million tonnes at 0.58% copper equivalent
- Metallurgical testwork shows strong recoveries of copper, antimony, and silver
- Priority drilling programs planned including deep diamond and shallow RC holes
Exploration Advances at Bulla Park
West Cobar Metals Limited (ASX – WC1) has released an encouraging update on its Bulla Park copper-antimony-silver project in New South Wales. Recent surface geological mapping, combined with reinterpretation of geophysical data and drill results, has revealed new high-grade and shallow mineralisation targets. These findings suggest that only a fraction of the deposit’s potential has been tested to date.
The company’s technical team has focused on the area adjacent to a dominant west-southwest trending fault, where gravity imagery and chargeability induced polarisation (IP) surveys indicate significant zones of thick, untested mineralisation. This structural feature appears to control the distribution and grade of copper, antimony, and silver mineralisation, with evidence pointing to increasing thickness and grades closer to the fault zone.
Resource and Metallurgical Highlights
The Bulla Park deposit currently holds an Inferred Mineral Resource of approximately 20 million tonnes grading 0.58% copper equivalent, which includes copper, antimony, and silver. Metallurgical testwork has demonstrated robust recoveries, 94.6% for copper, 84.1% for antimony, and 82.6% for silver, indicating the potential for producing both a saleable copper-silver concentrate and an antimony sulphide product. These results underpin the economic viability of the polymetallic deposit and support further exploration and development.
Targeting Higher Grades and Extensions
West Cobar’s reassessment of drill data and geophysical surveys, particularly gravity and IP chargeability imagery, has identified large areas of alteration and veining that remain untested, especially to the east of the current resource boundary. New surface mapping has also detected siderite-barite alteration and stockwork veins near surface, suggesting extensions of shallow mineralisation to the north and east.
To capitalise on these insights, the company has outlined a priority drilling program. This includes deep diamond drilling to test chargeability anomalies and the fault zone at depth, as well as shallower reverse circulation (RC) drilling to explore potential higher-grade zones closer to surface. These efforts aim to both extend the known mineralisation and define areas of higher grade, which could enhance the project’s overall economics.
Strategic Location and Next Steps
Located 110 kilometres west of the established Cobar mining hub, Bulla Park benefits from existing infrastructure, which could facilitate future development. West Cobar Metals continues to refine its geological and metallurgical models, with further drilling planned subject to funding availability. The company’s Managing Director, Matt Szwedzicki, emphasised that the project’s potential remains largely untapped and that the new targets provide clear opportunities for resource growth.
As West Cobar advances its exploration programs, market participants will be watching closely for drilling results that could confirm the presence of higher-grade mineralisation and support a resource upgrade. The company’s methodical approach, combining detailed mapping, geophysics, and metallurgical testing, positions Bulla Park as a compelling polymetallic project in the Australian base metals sector.
Bottom Line?
West Cobar’s upcoming drilling campaigns at Bulla Park could unlock significant resource growth, setting the stage for the project’s next development phase.
Questions in the middle?
- Will the planned deep diamond drilling confirm higher-grade mineralisation adjacent to the fault zone?
- How might new drilling results impact the current Inferred Mineral Resource estimate?
- What are the timelines and funding prospects for advancing Bulla Park towards development?
