The anomaly at a new prospect called Wongawar has been identified through a combination of rock chip and soil sampling.
Rock chip samples have recorded assays of up to 1.17 g/t gold and 693 ppm copper with anomalism extending over a contact length of 700 metres.
Managing director Neil Marston said: “The sampling results at Wongawar prospect are very encouraging because they indicate a highly prospective anomaly over a wide area in what is very unexplored terrain.
“At Wongawar we now have several samples anomalous in gold and copper.”
Results received are a strong indication of orogenic gold and/or volcanic massive sulphide (VMS) systems.
Wongawar prospect was first identified as a prospective area in 2017 during regional mapping by a consultant geologist who collected four rock chip samples in 2018.
The best of these samples assayed 1.17 g/t gold and 233 ppm copper.
This area’s prospectivity was confirmed through follow-up sampling by in-house geologists who collected a further four samples.
Best gold results were 1.02 g/t and 0.8 g/t while other samples assayed 693 ppm and 632 ppm copper.
A further three samples collected around 700 metres to the southwest of the previous sampling were anomalous in copper with one assaying 658 ppm.
This area was covered by the company’s 2018 soil geochemical survey which included sampling on a wide-spaced grid completed over several tenements.
Infill soil sampling
Following a detailed review of data, infill soil sampling was completed at Wongawar in late 2018 with 55 geochemical soil samples collected.
This was in addition to infill sampling at the company’s Windalah prospect.
Bryah used the latest laboratory-developed technologies of four acid digestion method to analyse the samples.
Mobile Metal Ion survey planned
During December 2018 an orientation Mobile Metal Ion (MMI) survey was completed at Windalah to determine if such a method could be used as part of a follow-up soil geochemical sampling program.
This proved successful and an MMI survey over Wongawar to test for copper-gold mineralisation is planned for later this month ahead of a drilling program.
The drilling has Department of Mines, Industry Regulation and Safety (DMIRS) Program of Works (POW) approval and heritage clearance.
Marston said: “We look forward to completing our MMI soil survey ahead of drilling to test this copper-gold exploration target.
“I am extremely pleased to announce these very encouraging exploration results for Bryah, the latest in a series of excellent milestones for the company.”
Manganese drilling upcoming
Meantime, Bryah’s field geologists are mobilising to the site to prepare for drilling around the Horseshoe South Manganese Mine on a granted mining lease.
It was the largest manganese mine in the Bryah Basin and is 1-kilometre north of the privately-owned Horseshoe Flats Manganese Mine which began production in 2017.
The DMIRS has approved the POW for Brumby Creek manganese prospect which allows Bryah to begin drilling this high-priority target along with others at Horseshoe South Manganese Mine and Devils Hill.
Marsten added: “Importantly, we are also preparing to drill some of our exciting manganese targets, now that all site access approvals are in place.”
