Junior Bryah Resources has reported a 31.3-million-tonne nickel/copper/cobalt mineral resource estimate for the Australian Vanadium deposit, at its Gabanintha project in Western Australia.

Fellow-listed Australian Vanadium, which holds the mineral rights to the vanadium, titanium, iron and cobalt at the deposit, is currently undertaking a bankable feasibility study for a vanadium operation.



Bryah has upgraded resources at its Gabanintha project in Western Australia that includes an indicated component within planned open pits.

The resource at Gabanintha now stands at 31.3 million tonnes grading 761 parts per million (ppm) nickel, 210ppm copper and 228ppm cobalt, or a contained resource of 23,770t of nickel, 6,556t of copper and 7,116t of cobalt.

That’s a 119 per cent increase from the previous estimate.

Importantly, Bryah Resources (ASX:BYH) notes that this includes a higher confidence indicated resource of 17.7Mt at 760ppm nickel, 205ppm copper and 229ppm cobalt, situated within the high-grade vanadium zone (HG10) within the three planned open pits of the Australian Vanadium Project.

West Australian explorer Bryah Resources says it’s opened the way for a PFS on the potential for a base metals concentrate development with the announcement of an updated nickel, copper and cobalt resource at the Gabanintha project in central WA.
The indicated-inferred mineral resource of 31.3Mt @ 761ppm for 23,770t Ni, 210ppm for 6,556t Cu and 228ppm for 7,116t Co occurs within planned openpit mining areas at the project 100km N of Meekatharra. It represents a 119% increase from its previous estimate.
Bryah’s PFS will proceed separately from a current bankable feasibility study by Australian Vanadium, which holds mineral rights to vanadium, titanium, iron and cobalt at the Gabanintha project.

  • Bryah Resources (BYH) has identified a shallow off-hole conductor at the Windalah Prospect in Western Australia
  • In April, the company drilled eight reverse circulation (RC) holes to test below the volcanogenic massive sulphide (VMS) anomaly identified in previous work
  • Five of the RC holes were cased for downhole electromagnetic (DHEM) surveying with an anomaly identified in two of the holes
  • This anomaly measures roughly 110 metres in strike and 85 metres in depth and dips towards the southwest
  • Bryah is up 2.74 per cent and shares are trading at 7.5 cents


Down-hole electromagnetic work has identified Bryah’s target for exploration activities next week at the Windalah prospect in Western Australia.

Notably, the DHEM is in a stratigraphic location analogous to the nearby high-grade volcanogenic massive sulphide (VMS) Horseshoe Lights copper-gold mine.

The new shallow off-hole conductor was discovered from DHEM work carried out in eight new reverse circulation holes that were drilled in April to test below significant VMS pathfinder minerals identified in earlier soil sampling and aircore drilling.

Adding interest, Bryah Resources (ASX:BYH) notes previous drilling in the immediate area has also recorded some noteworthy gold results.


Small Caps

On the junior end of town is Bryah Resources (ASX: BYH) with its 60% interest in the Bryah Basin manganese joint venture.

OM is funding exploration to earn up to 70% of the manganese rights to 600sq km of Bryah’s tenement package in the region.

The joint venture includes the Horseshoe South manganese mine, which is the region’s largest historic manganese mine.

  • Bryah Resources (BYH) has reported high-grade manganese at the Bryah Basin Manganese joint venture project in WA following scans of core from recent diamond drilling
  • The non-destructive XRF analysis provides assay data at ten-centimetre intervals along the core to be acquired and evaluated
  • The core from one drill hole included 48 intervals grading between 30 and 40 per cent manganese and fifteen samples exceeding 40 per cent, with a peak grade of 52.6 per cent
  • BYH plans to use the core in a series of beneficiation tests to ascertain the best methods to produce a quality manganese product. Those results will flow into the company's mineral resource estimation work


Significant high-grade manganese has been detected in core scans taken from diamond drilling at the Bryah Basin Manganese Joint Venture project in WA.  

Core taken from drilling at the project, which is currently 60%-owned by Bryah Resources (ASX:BYH) and 40%-owned by OM (Manganese) Limited, was recently scanned using high-resolution non-destructive X-ray fluorescence (XRF) analysis with exciting results.

Scanning confirmed the presence of shallow, high-grade manganese, with some grades exceeding 50% manganese over 10cm intervals.

Results of core scanning for drill hole BRDD005 included 48 10cm intervals grading between 30% and 40% manganese, and 15 samples above 40% manganese, with a peak grade of 52.6% manganese over one 10cm interval.



Drilling is now underway at Bryah’s namesake project with the first holes testing the Windalah prospect, a lookalike of the historical Horseshoe Lights copper-gold mine.

Horseshoe Lights, located 13km to the north, is a historical mine that produced 3.3 million tonnes of ore grading 2.9 grams per tonne gold and 1.7 per cent copper since its discovery in 1946 till production ended in 1994.

The company plans to complete about 8,000m of deep reverse circulation and diamond drilling at Windalah in three phases to test below significant volcanogenic massive sulphide (VMS) pathfinder minerals identified in earlier soil sampling and aircore drilling.


The Market Herald

  • Bryah Resources (BYH) has begun a major drilling program at its Windalah Prospect in Western Australia
  • Up to 8000 metres of reverse circulation (RC) and diamond drilling will be undertaken to test below a multi-element volcanic massive sulphide target
  • Drilling will be carried out in three phases to allow for downhole electromagnetic (DHEM) surveys to be completed between each phase
  • Bryah may add extra holes to the program once initial results are received
  • Shares in Bryah are up 4.29 per cent and are trading at 7.3 cents
