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.

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.


The Market Herald


  • 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

RC And Diamond Drilling Campaign Underway In WA

Bryah Resources Limited (ASX:BYH) has commenced a major drilling programme at the company’s Windalah Prospect within its Bryah Basin Project located in central Western Australia.

The company plans to drill approximately 8,000m of Reverse Circulation (RC) /diamond drilling to depths of 350 metres to test below the significant multi- element pathfinder minerals anomaly identified in earlier soil sampling and aircore drilling. This deep drilling is planned to be done in three phases to enable the completion and interpretation of down hole electromagnetic (DHEM) surveys between each drilling phase.

Managing Director, Neil Marston, said Phase 1 RC/diamond drilling of 2,000m is scheduled to commence in the coming days with holes to be prepared for follow-up DHEM surveying.

High-quality copper prospects are becoming hard to find, but juniors are poised for the challenge.



Bryah is embarking on a major drilling campaign to test the Windalah copper-gold prospect and other high-priority targets within its Bryah Basin project.

Windalah is the first cab off the rank with the company planning to carry out about 8,000m of reverse circulation and diamond drilling to depths of 350m to test below significant volcanogenic massive sulphide (VMS) pathfinder minerals identified in earlier soil sampling and aircore drilling.

Recent aircore drilling results included up to 455 parts per million arsenic, 48.5ppm antimony and 12.7ppm molybdenum.


The Market Herald

  • Bryah Resources (BYH) will begin an 18,000-metre drilling campaign in the coming days at its Bryah Basin Project in Western Australia
  • The company will complete 8000 metres of reverse circulation and diamond drilling beneath previously unearthed volcanic massive sulfide pathfinder elements at the Windalah prospect
  • This will be followed by 10,000 metres of aircore drilling across several prospects, which the company expects to begin in May
  • Shares last traded at 6.9 cents
