Recently completed diamond drilling at Bryah’s manganese assets intersected mineralisation consistent with the geological interpretation from earlier drilling.

This is particularly notable given that previous drilling had intersected high-grade mineralisation.

Bryah Resources (ASX:BYH) highlighted drill hole BRDD005 that tested a high-grade zone of manganese identified by reverse circulation drilling at Area 74 within the Brumby Creek prospect.

Zones of blue-grey high-grade manganese are clearly visible in the BRDD005 drill core and are generally separate from the red-brown iron rich shale zones.

Over the coming weeks, the full drill core will be analysed using continuous non-destructive XRF scanning that allows chemical assay data to be acquired and evaluated at 10cm intervals.

Interpreting the data at this high resolution will play an important part in the ultimate design of the beneficiation testwork program.

Testwork program

Samples from the drill core will also be taken for use in beneficiation and comminution testwork.

Beneficiation test will include ore sorting and dense media separation trials to determine the most efficient beneficiation path.

The company noted that the Horseshoe South mine, Horseshoe South Extended and the nearby Horseshoe flats have historically produced saleable manganese products.

Notably, a dense media separation plant was used to process material from Horseshoe South and Horseshoe South Extended to produce manganese ore.

Once beneficiation testwork is completed, the company plans to finalise mineral resource estimates for the Horseshoe South, Brumby Creek and Black Hill areas.

All activities are funded by partner OM Manganese (OMM), a subsidiary of large-scale miner and processor OM Holdings (ASX:OMH), which is earning up to a 51 per cent interest in their Bryah Basin Manganese Joint Venture.
