Australian manganese explorer and developer, Black Canyon Limited (Black Canyon or the Company) (ASX:BCA) has announced the discovery of high grade manganese at the W2 prospect in Wandanya, located 80 km south of the Woodie Woodie Mine. The drilling has intersected high grade manganese with portable XRF (pXRF) analysis indicating grade ranges of between 15% to 55% Mn. The mineralisation is interpreted as fault related hydrothermal, stratabound manganese enrichment representing a significant new exploration model on the eastern margin of the Oakover Basin.
It was exciting to be back on the rig and drilling the first holes into the W2 prospect. With each hole drilled we began to build a picture of the distribution, thickness and internal structure of the mineralisation. What was of particular interest was the consistency of the horizon over 240m strike and how we intersected mineralisation on the eastern most holes on every line so the mineralisation remains open to the north, south and east. 'Iron alteration and brecciation often associated from manganese mineralisation at Woodie Woodie was also observed. Significantly the age of the rocks we have drilled at W2 are younger than the rocks that host Woodie Woodie however similar processes may have occurred providing manganese rich fluids access to receptive units to form this stratabound mineralisation. The main advantage of this style of mineralisation is the benefit of hydrothermal high grades with the predictability of a mineralised layer which may extend over hundreds of metres and vary in thickness. It is very early days but I am very impressed with the geology, initial pXRF results and the future exploration potential using this new mineralisation model.

The mineralisation is interpreted as fault related hydrothermal, stratabound manganese enrichment representing a significant new exploration model on the eastern margin of the Oakover Basin. The company's Managing Director, Brendan Cummins, expressed excitement about the discovery and highlighted the potential for future exploration using this new mineralisation model. The company is awaiting expedited laboratory-based manganese assay results for selected representative holes from W2 to confirm the pXRF results and has collected samples for density-based beneficiation test work to potentially produce a high-grade manganese product. The assay results are expected in mid-October and mid-November. The company holds a significant land holding totaling 2,100km2 in the underexplored Balfour Manganese Field and across the Oakover Basin, in Western Australia, with a Global Mineral Resource (Measured, Indicated & Inferred) of 314 Mt @ 10.4% Mn defined across the Balfour Manganese Field projects.
