A 30-hole 6,000m reverse circulation drilling program completed in March has laid the foundations for an upgraded mineral resource estimate at the Cork Tree Well project north of Laverton in WA.

Brightstar Resources (ASX:BTR) says assays for around 13 holes have been received, with 17 holes still pending as part of the infill and extensional RC drill program, designed to identify mineralisation outside of the current JORC mineral resource estimate (MRE).

In an endeavour to grow the MRE and increase the confidence category in sections of the model from Inferred to Indicated, BTR says the latest results confirm extensions of the mineralised lode both along strike and at depth.

Gold hits received to date include 2m at 4.23g/t gold from 106m, 2m at 3g/t gold from 140m, 4m at 1.88g/t gold from 152m, and 2m at 2.11g/t gold from 125m and 1m at 1.56g/t gold from 135m.


Advancing Cork Tree Well towards production scenarios

“The intersections received encouragingly indicate that the mineralisation is still open at depth and along strike where we have received assays to date,” BTR managing director Alex Rovira says.

“Drill planning is underway for further follow up drilling at Cork Tree Well in 2023, targeting additional growth focused RC drilling and will incorporate diamond drilling for metallurgical and geotechnical assessments.

“A potential increase in the MRE at Cork Tree Well – in combination with a successful completion of the merger with Kingwest Resources targeted for completion in May – will see Brightstar control a significant JORC mineral resource in the Laverton-Leonora District.

“It will also provide critical mass to advance the projects towards potential production scenarios in a strengthening gold price environment.”

For now, Rovira says the existing processing infrastructure at Brightstar holds the potential to facilitate a low-capital and fast-tracked restart for operations, subject to necessary approvals and feasibility studies underway.


What’s next?

Further assays will be reported as they are received and will be utilised in the planning stages of the next drilling program at Cork Tree Well.

These final results will be incorporated into a new geological model forming the basis of an updated MRE and identifying areas for infill drilling.

This upgraded MRE will be included within mining studies currently underway and due for delivery mid-year.

Future drill campaigns will also incorporate diamond holes to support metallurgical and geotechnical studies to progress the project towards potential mining operations.
