Bryah diamond drilling to test deep mineralisation at Windalah
Link copied to
Bryah has kicked off the first ever diamond drilling at the Windalah copper-gold prospect within its namesake project to test for mineralisation at depth.
The program of three diamond tails and two new holes totalling more than 1,000m will test along strike and beneath the broad sulphide-rich zone with highly elevated volcanogenic massive sulphide (VMS) pathfinder minerals.
Previous reverse circulation drilling by Bryah Resources (ASX:BYH) earlier this year had intersected a broad disseminated to semi-massive sulphide zone with highly elevated antimony and arsenic that is considered to be the source of the surface VMS pathfinder element anomaly.
“This is the first diamond drilling ever undertaken at Windalah, an area we believe holds significant potential for copper-gold mineralisation at depth,” managing director Neil Marston said.
“We have observed highly elevated key pathfinder minerals, including some copper, within a broad sulphide-rich zone in earlier drilling. This zone also lies in the same stratigraphy as the nearby known high-grade copper-gold deposit at Horseshoe Lights.
“Bryah Resources plans to drill over 1,000 metres of diamond core in this program testing this target zone and we look forward to seeing the results as they become available.”
Windalah is part of the company’s Bryah Basin project and strongly resembles the Horseshoe Lights deposit, a historical mine that produced 3.3 million tonnes of ore grading 2.9 grams per tonne gold and 1.7 per cent copper since its discovery in 1946 till production ended in 1994.
Bryah’s recent RC drilling had returned highly-elevated VMS pathfinder minerals as well as top copper hits of 2m at 0.23% copper from 132m and 4m at 0.12% copper from 136m, fuelling the company’s belief that it is closer to the copper-gold source.
All five diamond holes will be cased for down-hole electromagnetic surveying.
