Assays have been received from a reverse circulation program completed in June at the Delta 2 prospect, less than 2.5km from the recently improved Cork Tree Well (CTW) mineral resource estimate.
Results have demonstrated a very promising start to building new deposits in the CTW project area with hits including 2m at 6.05g/t gold from 29m, 1m at 5.31g/t gold from 102m, and 2m at 2.42g/t gold from 94m.
Around 12 reverse circulation holes were completed by Blue Spec Drilling at Delta 2 during May – July 2022 for a total of 1,782m.
The program was designed to test for an east dipping mineralised structure, striking north-south.
True scale of the opportunity yet to be unveiled
Brightstar (ASX:BTR) managing director Bill Hobba says the anomalous intersections confirm bedrock mineralisation over 300m along strike with mineralisation not effectively closed in any direction.
“This strengthens our belief in the potential for the CTW project area to produce multiple deposits,” he says.
“It is still early days, and the true scale of the opportunity is yet to be unveiled.”
Although the current intersections appear relatively thin and modest grade, Hobba adds they are incredibly encouraging at this stage of exploration of a new prospect and especially given its proximity to the main CTW mineral resource.
BTR will now focus on understanding the controls on mineralisation and seek to identify the better parts of the system with further drilling at Delta 2.
First major drilling at Alpha in eight years comes up swell
These results come hot on the heels of high-grade gold hits at the Alpha West Project, about 15kms from the Brightstar processing facility in the Laverton gold belt of Western Australia.
Around twelve holes for 1,260m were drilled 500m northwest of the Alpha ore body where assays returned 5m at 9.8g/t gold from 98m, 2m at 11.3g/t gold from 88m including 1m at 21.4g/t gold from 88m and 2m at 6.18g/t gold from 77m.
The results suggest the Alpha system, which contains a resource of 1.452Mt at 2.3g/t for 106,000oz, will become even more robust.
More drill holes will also be needed to improve the quality of the resource in the eastern part of the Alpha system, but the recent results suggest it will become even more robust.
Further drilling down dip and along strike is likely to be proposed by Brightstar along with infill drilling to improve the confidence of the existing Alpha resource for mining solutions and scheduling.
“This first round of drilling shows potential for further extensions of this western zone of the project in an area that has not previously been mined,” Hobba explains.
“When combined with potential for growth of the main Alpha lode we are eager to discover the true scale of this mineralised system.”
