Geochemical soil sampling at Bryah Resources’ (ASX: BYH) Bryah Basin project in Western Australia has uncovered a large-scale anomaly that may be associated with base metals and gold.
Soil sampling and on-ground mapping data have indicated to Bryah it has identified a large alteration cell that could be associated with volcanogenic massive sulphide and/or orogenic gold mineralisation.
The large anomaly was pinpointed immediately to the east of where drilling was carried out last year at the Windalah prospect and gold was intersected.
Speaking with Small Caps, Bryah managing director Neil Marston said identifying the anomaly via wide-spaced sampling was exactly what the company was hoping to achieve from the program.
He added the discovery “further vindicated” the company’s methodical exploration approach to the entire project.
“At Windalah we now have a significant alteration cell elevated in antimony, gold, arsenic and selenium as well as other important volcanogenic massive sulphide pathfinder elements.”
“To identify multiple pathfinder minerals for volcanogenic massive sulphide systems in the same location over two phases of sampling gives us great confidence that we are onto a alteration cell which is over 2km long,” he said.
In December last year, Bryah carried out an orientation mobile metal ion survey at Windalah to determine its effectiveness as a follow-up to soil sampling.
Initial results showed the mobile metal ion survey had detected low level gold in the vicinity of recent reverse circulation drilling at Windalah prospect.
Due to encouraging results from the survey, Bryah now plans to expand the mobile metal ion survey to include the large-scale multi-element anomaly to test for base and precious metals.
“We look forward to completing the next mobile metal ion survey at our Windalah prospect and other anomalous areas ahead of further drilling to test these copper-gold exploration targets,” Mr Marston said.
Previous success at Bryah Basin
To-date, Bryah Resources has unearthed manganese and gold across its Bryah Basin project.
In November last year, Bryah intersected 5m at 6.62 grams per tonne gold, including 1m at 15.05g/t gold; 3m at 6.69g/t gold, including 1m at 10.52g/t gold.
“We have intersected intervals exceeding 6g/t in two holes collared 100m apart, so the focus now will be to extend this high-grade mineralised horizon, which is open down dip and along strike,” Mr Marston noted at the time.
Additionally, the previous month, Bryah had intersected 27m at 1.43g/t gold and 21m at 1.21g/t gold at Windalah.
Meanwhile, rock chips throughout 2018 have returned high-grade manganese at the project with assay results in December revealing 54.5%, 51.4%, 49.9% and 45.4% manganese.
In this morning’s announcement, Bryah stated it expected to secure approvals to drill the Brumby Creek manganese prospect within the next few weeks.
