Brightstar Resources Limited (ASX: BTR) has received high-grade gold assays up to 109.6 g/t from its +2,000m RC drilling programme at Cork Tree Well (CTW), located 30km north of Laverton in the prolific Laverton Gold Belt of Western Australia.
We are pleased to receive the final assays from the Laverton Gold Project RC program, after successful completion of the recent drilling at Menzies,” Managing Director, Alex Rovira, said.
“The Cork Tree Well programme had two defined objectives – the first being infill drilling at the Delta zone within the CTW mineral resource to provide better understanding on the structures controlling the higher-grade mineralisation, and the second to test the higher grade plunging shoot within the CTW main system as a follow up to drilling earlier in the year, which indicated mineralisation that has the potential for possible extraction using underground mining methods.
“At Delta, the three-hole programme saw the holes drilled on different orientations to the historic drilling that has previously tested the broadly North-South striking system at CTW. Encouragingly, the results indicate that the structures containing the mineralisation are different to the main CTW zone and see both a lithological and orientation change, which may be due to the confluence of multiple structures hosting the gold mineralisation.
“This requires further follow up and significantly increases the potential for definition of further mineralisation at Delta and to the north, which is open for a further 3km. Brightstar has booked aircore drilling contractors to mobilise in early September for a ~4,500m campaign, which is intended to define targets for follow up RC drilling.
“With the scoping study nearing finalisation, planning for further RC and Diamond drilling at Menzies and Laverton is underway to commence later in the year in order to continue to grow the mineral resource base, upgrading resources within early-stage mining areas, and advance the projects towards near term production opportunities.”
The drilling program at Cork Tree Well was focused on two defined areas, namely the Delta Prospect to the north, and a high-grade plunging shoot within the main CTW ore body.
Next Steps
These results are being utilised in the planning stages of the next drilling program at CTW, where the mineralisation remains open in several vectors (dip, plunge, strike) which requires further drill testing to define the limits of the mineralisation and to continue to grow the mineral resource estimate.
Diamond drilling is also being planned to provide improved structural information that will allow for more informed targeting and inform a new geotechnical model for mine planning purposes.
Brightstar has booked a 4,500m aircore drilling programme at Cork Tree Well North, to commence in early September.
