West Cobar Metals Ltd (ASX:WC1) has defined a maiden inferred resource of 19.7 million tonnes (Mt) of 0.58% copper equivalent (CuEq) – or 0.30% Cu, 0.10% antimony (Sb), 4.7 g/t silver (Ag) – at its Bulla Park project in New South Wales.

This is based on a cutoff grade of 0.21% Cu.

Additionally, the project’s copper-antimony-silver mineralisation is open along strike and down dip, and WC1 has been able to set an exploration target of 30Mt to 50Mt of 0.47% to 0.66% Cu equivalent – or 0.23 to 0.33% Cu and 0.08 to 0.12% Sb and 4 to 6g/t Ag – alongside the MRE.

Development of this target was based on an assessment of exploration drill results and geophysical data.

Looking ahead, the company anticipates that Bulla Park’s large tonnage and the thick zone (>60m) of mineralisation will enable bulk mining methods – potentially including open pit mining – while the project’s strong metallurgical characteristics should facilitate production of a copper-silver concentrate and a separate, saleable antimony product such as antimony sulphide.

Located in NSW’s Cobar mining district, Bulla Park has silver mineralisation based mostly of disseminated tetrahedrite with minor amounts of chalcopyrite and stibnite.

WC1 has previously conducted metallurgical test work yielding a relatively clean copper-silver concentrate and a separate antimony product, with no significant contaminant minerals present apart from arsenic, which is able to be removed separately during the leach process.

This included recoveries of 94.6% copper, 82.6% antimony and 84.1% silver to date, but further testing is expected to improve these.
