West Cobar Unveils Promising Maiden Resource at Bulla Park with Strong Copper, Antimony and Silver Potential

Highlights

• Maiden inferred resource of 19.7Mt @ 0.58% copper-equivalent 
• Exploration target indicates up to 50Mt potential 
• High recovery rates from recent metallurgical testing 

West Cobar Metals (ASX:WC1) has announced a significant milestone at its Bulla Park Project in New South Wales, revealing a maiden inferred mineral resource estimate of 19.7 million tonnes at 0.58% copper-equivalent. The estimate was independently calculated by Lily Valley International and marks a key step in the project’s progression. 

The newly defined resource includes approximately 59,000 tonnes of copper, 20,000 tonnes of antimony, and 3 million ounces of silver, underscoring the polymetallic potential of the site. In addition to the maiden resource, the company has also outlined an exploration target ranging between 30 million and 50 million tonnes at grades ranging from 0.47% to 0.66% copper-equivalent. 

The company is moving forward with an expanded exploration strategy that includes further reverse circulation and diamond drilling. These upcoming programs aim to extend the current resource footprint and identify higher-grade zones, particularly around the WSW fault where mineralisation has been observed over 60 metres in thickness. 

One of the key focuses in the next phase of work is diamond drilling to test deeper zones within the fault area, as well as assessing the potential for new mineralised zones across the broader tenement. This effort is aligned with the company’s objective to build scale and support a large-scale, bulk-mining open-cut operation in the region. 

Metallurgical testing is also advancing in parallel. Current testwork has achieved recoveries of 94.6% for copper, 82.6% for antimony, and 84.1% for silver. Ongoing test programs are targeting flotation and leach optimisation processes, along with refining a precipitation method to produce a final antimony product. These developments aim to enhance the commercial viability of the project through efficient extraction and processing of its multi-metal content. 

According to the company, the unique mineralisation style at Bulla Park is expected to facilitate the extraction of its valuable metals, reinforcing its potential as a critical minerals asset. The project spans 518 square kilometres and is held under four granted exploration licences through Bulla Park Metals, a wholly owned subsidiary of West Cobar Metals. 

West Cobar (WC1) continues to focus on developing its portfolio of critical mineral projects across Australia, positioning itself to support the growing demand for key industrial metals.
