Bryah firms up Gabanintha gold potential
Link copied to
Gold has been uncovered at the Gabanintha project in central Western Australia, where Bryah Resources (ASX:BYH) holds a suite of mineral rights.
Up to 3 grams per tonne (g/t) gold were recorded in the latest assay results from an initial selection of historical drill samples from Australian Vanadium’s (ASX:AVL) namesake project within Gabanintha.
Additionally, a review of metallurgical test work undertaken by AVL showed the presence of gold along with cobalt, nickel and copper in the non-magnetic tail after separation of the vanadium, titanium and magnetite.
AVL holds the tenements and rights to vanadium, titanium, cobalt, iron ore, lithium, chromium, uranium, tantalum and manganese while Bryah has the rights to all other minerals.
“We are very pleased to have identified the presence of gold mineralisation within Australian Vanadium Limited’s high-grade vanadium-titanium-magnetite deposit at Gabanintha,” Bryah managing director Neil Marston said.
“Given the sheer scale of the vanadium deposit and its long mine-life potential, these initial results warrant us undertaking a more detailed investigation on the extent of gold mineralisation.
“Further drilling samples will be submitted for gold analysis in the coming days with our expectation of more testing to follow.”
He added that the nickel-copper-cobalt sulphide mineralisation where gold is present has consistently reported to the non-magnetic fraction during the magnetic separation of the vanadium bearing magnetite.
“This has effectively concentrated the sulphide minerals, enabling further concentration by flotation methods,” Marston explained.
“The additional presence of gold in the sulphide nickel-copper-cobalt concentrate could significantly improve the economics of producing this by-product from the project.”
A review of metallurgical test work found that sulphide concentrates from flotation of non-magnetic fraction contained up to 6.3% base metals including up to 2.02% cobalt, 2.58% nickel and 1.70% copper.
Additionally, the concentrates contain up to 23.4g/t gold, indicating that gold is associated with the sulphide minerals in the deposit.
Testing of historical drill samples has recorded anomalous gold over a 1.4km strike to date.
Bryah is currently carrying out a follow-up program of gold analysis of archived drill samples as the 450 samples assayed to date represents just 2 per cent of the total available.
It will also work with AVL to update the cobalt-nickel-copper resource, which is currently at 14.3Mt at 666 parts per million nickel and 217ppm copper, using all drilling completed in 2019 and 2020.
