Bryah Resources Ltd (ASX:BYH) has started a 5,500-metre aircore (AC) drilling program testing four gold-copper prospects within the Bryah Basin Project in Western Australia.
The program, which is expected to take 2-3 weeks, aims to complete testing the large geochemical anomaly at Windalah East and undertake first pass reconnaissance drilling for gold-copper at the Wongawar, Fortnum East and Fiddlers East prospects.
Tenement location plan.
“Most substantial" program of 2020
Managing director Neil Marston said: “This is the most substantial drilling program undertaken by the company this year.
"These areas have been carefully identified by the company, with in-depth consideration given to encouraging geological information.
"The new target areas are all highly prospective for gold and copper."
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, is the main focus of this program.
Minimum of 30 holes planned
In March 2020, Bryah completed eight AC drill holes for 669 metres before COVID-19 caused an early suspension of the drilling program.
A minimum of 30 holes for a total of about 2,500 metres of AC drilling are planned in this current program to fully test this geochemical anomaly.
Additionally, a further nine holes for around 900 metres are planned to test a gravity low anomaly at Windalah along a single line of holes at 80 metres spacing.
Undrilled prospect areas
As part of this program, a series of traverses will also be drilled for a minimum of 2,000 metres across the Wongawar, Fortnum East and Fiddlers East gold-copper prospects, which is the first time the company has drilled these target areas.
Recent sampling at Wongawar has returned gold and copper anomalism in soil and rock chip sampling of up to 1.17 g/t gold and 693 ppm copper over a 700-metre contact length.
This site was first discovered in 1989 through a BLEG soil sampling campaign which identified gold anomalism.
Fortnum East Prospect, which has had very limited historical exploration, has potential for epigenetic or VMS-style mineralisation.
Fiddlers East has been previously highlighted as an area of interest for Horseshoe Lights-style gold-copper mineralisation.
The planned drilling area lies around 5 kilometres to the east of the Horseshoe Lights open pit, which historically has produced more than 54,800 tonnes of copper and 309,700 ounces gold.
