Bryah Resources Ltd (ASX:BYH) has completed 2,015 metres of reverse circulation (RC) drilling at Windalah and Mars gold prospects in the Bryah Basin of Western Australia and has detected off-hole anomaly responses in a down hole electromagnetic (EM) survey.
The company is encouraged by the survey results which could be indicative of bedrock conductors caused by volcanogenic massive sulphide (VMS) mineralisation sources.
Two deep RC drill holes for a total of 650 metres were drilled at PH1, which sits around 7 kilometres north of the Peak Hill Gold Mine and 65 kilometres west of Sandfire Resources Ltd’s (ASX:SFR) DeGrussa Copper-Gold Mine.
Bryah managing director Neil Marston said: “At the PH1 EM target, we drill tested a conductor zone modelled from airborne and ground EM surveys.
“Follow-up down hole EM surveying has confirmed the presence of a conductive source, which is possibly one or more bedrock conductors sitting just off the drill hole traces.
“The DHEM survey results are extremely encouraging, and we expect to undertake further drilling at PH1 as soon as all our interpretative work is completed in August.”
Detailed modelling of the DHEM survey data is underway with the company’s geophysical consultants utilising all the geological, geochemical (including pending assays), and other geophysical data acquired for EM conductor plate modelling ahead of follow-up drilling.

RC drilling program
As well as the two RC holes on PH1, the drilling program included:
- Seven RC drill holes for a total of 1,134 metres at the Windalah prospect, where 2018 and recent 2020 RC drilling returned exceptional high-grade gold intersections, and;
- Two RC drill holes for a total of 231 metres at the Mars prospect, where historical drilling intersected gold mineralisation along a 500 metres zone within P52/15272.
Marston said: “We have successfully completed this initial RC drilling program, one of several drilling campaigns we plan to undertake over the remainder of 2020 to test some of our excellent gold and copper targets.
“We look forward to receiving the assay results next month which will guide our follow-up drilling activities.”
Assay results are expected to be reported in August 2020.
