Bryah Resources says assays from its Bryah Basin Olympus copper gold project have confirmed VMS type copper-gold mineralisation.

The 2,000m RC drilling was co-funded with $130,000 granted in round 24 of the Western Australian Government’s EIS (Exploration Incentive Scheme) to test the Olympus geochemical anomaly (OGA) on the northern limb of the Mars Dome.

And semi massive sulphide mineralisation, anomalous copper up to 0.1% and highly anomalous Volcanogenic Hosted Massive Sulphide (VHMS) pathfinder elements were identified.

Byrah (ASX:BYH) is planning to follow up RC drilling to test these targets.

Targeting clusters of VMS deposits

CEO Ashley Jones said the State funded EIS grant enabled the company to fast track this prospect by going straight to deep RC drilling – which successfully identified anomalous copper and multi element trends similar to the Windalah project.

“This drilling will aid us in generating drill targets,” he said.

“VMS deposits often form in clusters and having two projects, Windalah and Olympus, with similar geochemical anomalies is exciting.

“The aim of this deeper initial drilling was to target the fresh rock and help target the prospective horizon faster.

“The right lithologies were intersected and further drilling will be warranted based on the anomalous results received.”

The main prospective horizon based on the Windalah prospect hasn’t been intersected yet, so that will be the target of further programs, Jones said.

Follow-up drilling planned

Follow up downhole electromagnetic (DHEM) surveys are planned to test for off-hole conductors that may correspond with copper sulphide mineralisation.

A pair of diamond holes targeting depth extensions of massive sulphide intersected in shallower drilling is anticipated to commence in September 2022.

Plus, follow-up RC drilling is planned to take place at Olympus, focussing on generating multiple sections that intersect the mineralised stratigraphic horizon.
