The search for copper and gold riches at Bryah Resources’ Windalah anomaly is getting warmer as aircore drilling continues to grow the strike-length and prospectivity of the VMS target.

Aircore drilling by Bryah (ASX:BYH) has boosted the strike length of the multi-element anomaly well beyond 500m.

Results of 986 ppm arsenic and 136 ppm antimony in hole 21WEAC053 and up to 17 ppm molybdenum in hole 21WEAC052 may not provide direct evidence of a major copper or gold find, but they do show the pathfinders of a big VMS system are there – and at higher levels than previous aircore drilling in 2020.

They bear similarities to the pathfinders for the historic Horseshoe Lights gold and copper mine, located just 13km away as the crow flies from Bryah’s Windalah target.

Copper results were also identified over 1m intervals of 0.22% copper in hole 21WEAC044 and 0.13%Cu in the adjacent hole 21WEAC052.

“Aircore drilling completed last year identified a coherent multi-element anomalous zone over a strike length exceeding 500m which was open to the west,” Bryah MD Neil Marston said.

“This latest drilling has confirmed that the multi-element anomaly extends further west and has increased in intensity.”

Diamond drilling to capitalise on aircore success

Bryah sunk 31 aircore drill holes for 2,537m at Windalah in its latest program, having identified a suite of elements in aircore drilling so far.

Eight of the holes drilled recorded elevated copper values above 500 parts per million, with five holes also recording highly anomalous results in key pathfinder minerals arsenic and/or antimony.

Deep drilling has already begun, with the first diamond drill hole completed to a depth of 350m and another currently being drilled.

A third will follow that to test beneath the geochemical anomaly at Windalah with samples taken from the project, some 150km north of Meekatharra, to Perth for testing.

Diamond tails have been completed as well on three RC drill holes and cased for down hole electromagnetic surveys.

“We have a diamond core rig on site at the moment testing beneath these aircore holes and we look forward to reporting the results of this deep drilling program as soon as information becomes available,” Marston said.
