Bryah closes in on a large ‘Degrussa-like’ copper-gold target

Exploration is ramping up at Bryah Resources’ Bryah Basin project in WA, with a 4000m drilling program and follow-up geophysical surveys now underway on an exciting VMS copper-gold target.
The Bryah Basin hosts some world class Volcanogenic Massive Sulphide (VMS) copper-gold deposits, like Sandfire’s DeGrussa, but remains largely underexplored.
Bryah Resources’ (ASX:BYH) discovery of a VMS target at ‘Windalah’ has confirmed the potential for a new copper-gold discovery on this highly prospective land package.
In April 2021, Bryah completed eight Reverse Circulation (RC) drill holes to depths of up to 350m to test below the significant Volcanogenic Massive Sulphide (VMS) pathfinder minerals anomaly identified in earlier soil sampling and aircore drilling.
Assay results from this RC drilling program are due within two weeks.
Recently, a down hole electromagnetic (DHEM) anomaly was detected in two surveyed RC holes.
Bryah’s modelled DHEM anomaly conductor plate is near surface, has a strike length of approximately 110 metres, a depth extent of 85m and dips towards the south-west.
DHEM surveying involves sending a probe attached to a wire cable down a completed drill-hole.
The probe is able to detect conductive sulphide mineralisation off-hole, with the potential to “see” mineralisation up to 75m away.
The technique is widely used in base metal exploration, and has played a pivotal role in some of the share market’s most famous discoveries – like DeGrussa and Monty and Sirius Resources’ Nova-Bollinger.
Follow up surveying plus 4,000 metres of aircore drilling at the Windalah and Mount Labouchere Nickel-Copper-Cobalt Prospects has now commenced.
Some of these holes will be drilled directly into the modelled DHEM conductor plate zone.
A major Gradient Array Induced Polarisation (GAIP) survey over the Brumby Creek Manganese Prospect area is expected to commence next week.
In 2020, a GAIP survey was successfully used to identify a shallow high-grade manganese deposit in a trial completed at Brumby Creek.
These GAIP survey activities are being fully funded by OM (Manganese) Ltd as part of the Bryah Basin Manganese Joint Venture.
