West Cobar Metals has landed a grab bag of significant thick intersections of copper, silver, lead and zinc mineralisation at its Bulla Park prospect in NSW with drill hits spanning over a 1 kilometre strike. Significant assays returned include a 22 metre intercept grading 1 per cent lead and 20 grams per tonne silver from 253m downhole.

West Cobar Metals has landed a grab bag of significant, thick intersections of copper, silver, lead and zinc mineralisation at its Bulla Park prospect in NSW with drill hits spanning over a 1 kilometre strike. Significant assays returned include a 22 metre intercept grading 1 per cent lead and 20 grams per tonne silver from 253m downhole.

The Bulla Park project is located on the western portion of the Cobar Basin in central New South Wales and hosts a polymetallic picnic.

Assays received from the first phase of drilling consisting of 295m of mud rotary drilling and 1762m of diamond drilling at Bulla Park have all been returned.

Drill targets are now being defined and refined from the assay data to test and extend the multi commodity zones intersected in the latest round of drilling.

Assays from the initial three holes drilled at the Bulla Park prospect all returned low grade copper intersections that West Cobar says confirms the model for copper mineralisation. The system is still open to the south however it weakens to the north and west.

The fourth drill hole aimed at testing the southern extension of the copper zone returned an intercept of 22m grading 1.0 per cent lead and 20 g/t silver from 253m downhole including a 4m internal going 0.29 per cent zinc from 270m. Mineralisation in the fourth hole was accompanied by disseminated galena, chalcopyrite and sphalerite or lead, copper and zinc sulphides respectively.

Results from the fifth diamond drill hole returned 6.8m going 0.42 per cent lead and 10 g/t silver from 30m downhole. The fifth drillhole was drilled as a step out hole approximately 2km to the northeast of the other drill holes confirming the widespread mineralisation zone according to the company.

West Cobar says historical and current drilling has defined an overall mineralisation zone spanning 1km by 500m at Bulla Park that is still open to the south.

The drill rig is now going to head to West Cobar’s Mount Jack copper-gold prospect located approximately 120km to the northwest of Bulla Park with drilling pencilled in to commence early January.

A single diamond hole is planned to be drilled to test an aeromagnetic target that West Cobar says resembles a classic “Cobar-style copper-gold target”.

West Cobar Chief Executive Officer, David Pascoe said:

“The results from the initial phase of diamond drilling at Bulla Park have confirmed our model of stratabound and extensive mineralisation. This zone extends for at least 1km and is completely open to the south. There is clearly potential for a major multi-commodity deposit and we will seek to define targets for future drilling.”

“In the meantime, the Mount Jack prospect provides a clear, compelling target for a Cobar style copper-gold deposit and will be drilled in early January, if accessible.” 

With a polymetallic play spanning 1km by 500m at its Bulla Park prospect, West Cobar looks to have plenty of options ahead of designing a follow up drill program to pepper its prospective tenure in 2022.
