Bryah Resources Ltd (ASX:BYH) has completed an aircore (AC) drilling program of 67 holes for 5,998 metres at four high-priority gold-copper prospects within the Bryah Basin Project, in Western Australia.
The program was designed to:
- Complete aircore drilling over a large soil geochemical anomaly with Volcanogenic Massive Sulphide (VMS) potential at Windalah East prospect, and
- Undertake first pass reconnaissance drilling at the Wongawar, Fortnum East and Fiddlers East gold-copper prospects.
Samples from this program are with the laboratory or in transit and assay results are expected in late October 2020.
Windalah East geochemical anomaly
The large Windalah East geochemical anomaly was discovered in 2018 by 500 x 500-metre multi-element auger soil sampling, with follow up 250 x 250-metre infill sampling verifying the scale of the anomaly.
An area highly anomalous in pathfinder minerals including antimony, arsenic and selenium, which are often associated with the footwall alteration cells of hydrothermal VMS deposits, was the focus of this program.
In March 2020, the company completed eight AC drill holes for 669 metres before COVID-19 caused an early suspension of the program.
A total of 27 additional holes for 2,411 metres of AC drilling was completed in this program to test this geochemical anomaly.
In addition, nine holes for 888 metres were drilled to test a gravity low anomaly at Windalah with a single line of holes at 80-metre spacing.
The location of the prospects within the Bryah Basin.
As part of this program, 31 AC holes were drilled for 2,699 metres across the Wongawar, Fortnum East and Fiddlers East gold-copper prospects.
The Wongawar prospect is an epigenetic gold-copper target within the Peak Hill gold mine region with recent sampling returning gold and copper anomalism in soil and rock chip sampling of up to 1.17 g/t gold and 693 parts per million copper over a 700 metres contact length.
Ten AC holes for 806 metres have been drilled at the Wongawar prospect.
The company has completed 12 AC holes for 1,225 metres at Fortnum East prospect, a poorly exposed section of the prospective Narracoota Ravelstone Formation contact which has had very limited historical exploration.
At the Fiddlers East prospect, a total of nine AC holes for 668 metres have been drilled around 5 kilometres to the east of the Horseshoe Lights open pit.
