Bryah Resources Limited (ASX:BYH) has identified the presence of a broad, high-tenor down hole multi- element geochemical anomaly associated with copper and gold with A/C drilling at Windalah East in Western Australia.
The company has now completed a total 67 holes for 5,999m of AC drilling over four prospect areas.
Drilling at the Windalah East prospect has also returned highly anomalous results in Volcanogenic Massive Sulphide (VMS) pathfinder minerals including, up to 455 ppm Arsenic, up to 48.5 ppm Antimony and up to 12.7 ppm Molybdenum.
These minerals are commonly associated with VMS copper-gold deposits, including the nearby Horseshoe Lights high-grade copper-gold mine.
This anomalous multi-element zone provides the company with a coherent exploration target over a strike length exceeding 500 metres which is open to the north-west of the latest AC drilling.
Managing Director Neil Marston said that coincidently the anomalous zone is situated over an airborne electromagnetic (VTEM) target identified in 2018.
The discovery of this downhole geochemical anomaly is testament to excellent geological processes the Bryah technical team has been applying to the project and confirms the potential for a VMS copper-gold discovery on Bryah’s highly prospective tenement package,” Mr Marston said.
“We look forward to the next exciting phase of copper-gold exploration at Windalah, which will include a programme of targeted RC and diamond drilling planning for early 2021.”
Mr Marston said the latest drilling results are contributing to the company’s growing geological understanding in the area through 3D modelling. This knowledge will be used to re-evaluate the geophysical data acquired during the 2018 VTEM survey and 2019 gravity survey.
Planning is underway to commence a follow-up drilling programme in early 2021. Work is expected to include deep RC drilling of massive sulphide / intensely altered zones with follow-up downhole electromagnetic surveys. This will assist the Company as it attempts to delineate primary VMS high- grade Cu-Au mineralisation.
Further work will be undertaken to refine other targets elsewhere in the Mars Dome, most likely with aircore drilling.
