Bryah Resources Ltd (ASX:BYH) has returned from a trading halt after receiving broad gold hits in drilling at the Windalah prospect of the Bryah Basin project in central Western Australia.
Thick zones of gold mineralisation of up to 27 metres were recorded in 3-metre composite samples in four reverse circulation (RC) drill holes completed in August.

The aim of the program was to test up to six conductors identified by recent airborne Versatile Time-Domain Electromagnetic (VTEM) and ground Moving Loop Electromagnetic (MLEM) surveys.
Managing director Neil Marston said, “Today we have announced encouraging gold mineralisation has been recorded at the Windalah prospect, in the Bryah Basin.
“This area was identified earlier this year in airborne and ground electromagnetic survey work as having potential for VMS systems.”

Results include:
27 metres at 0.34 g/t gold from 18 metres; 27 metres at 1.43 g/t from 132 metres, including 3 metres at 4.16 g/t from 135 metres and 3 metres at 6.29 g/t from 144 metres;
21 metres at 1.21 g/t from 66 metres, including 6 metres at 3.52 g/t from 78 metres;
12 metres at 0.71 g/t from 21 metres and 9 metres at 0.46 g/t from 42 metres; and
21 metres at 0.14 g/t from 30 metres.
Marston said, “Our exploration strategy, which is centred on a systematic approach to target generation, is now proving its merit.
“With this initial success, we are more confident about further deep drilling in this area as we believe the Windalah prospect has great potential for a future copper-gold discovery.”
Significant pyrite-chlorite plus sericite alteration zone was observed and the gold mineralisation appears open along strike and down dip.

Follow-up activities before the next round of drilling at Windalah prospect are:
Completion of laboratory analyses and reporting;
Down Hole Electromagnetic (DHEM) survey of cased holes; and
Geological, geochemical and geophysical interpretation and 3D modelling.
Heritage surveys and Department of Mines, Industry Regulation and Safety Program of Works approvals will be required for the next round of drilling.
At the Jupiter prospect, 4 kilometres southwest of the Horseshoe Lights copper-gold mine, a drilling program encountered difficult ground conditions and was wound up after seven holes.
Despite the conditions, wet sample recovery and lack of significant gold or copper being recorded, the geology intersected was highly encouraging with zones of propylitic alteration with strong chlorite, sericite and epidote observed.
Follow-up diamond drilling appears warranted as part of future exploration to fully test this conductive area.
Sixteen holes for 1,361 metres have been drilled to test EM conductors identified at Mars 2, Mars 3, Mars 4 and Peak Hill 1.
Laboratory results for these holes are yet to be received.
