Black Canyon extended known manganese mineralisation at Wandanya 400m south, with a further 1.4km strike to test. The maiden resource estimate is due September 2026.
Alpha Score of 44 reflects weak overall profile with moderate momentum, poor value, weak quality, weak sentiment.
Black Canyon (ASX:BCA) has extended known manganese mineralisation at its Wandanya project in Western Australia by 400 metres to the south, the fourth and final batch of assay results from resource definition drilling shows.
The drilling covered the southern portion of a three-kilometre base case zone. Results show consistent zones of high-grade stratiform manganese. The extension pushes the known mineralisation beyond the original footprint.
Managing director Brendan Cummins said a further 1.4 kilometres of strike to the south remains untested and will be targeted in an upcoming expansion reverse-circulation drill program. The company expects that work to start shortly.
“The grade and thickness are remarkably consistent along and across strike with many intercepts indicating Direct Ship Ore potential and exceeding 40% manganese,” Cummins said in a statement.
“When you pair these exceptional drill intercepts, scale of the discovery and the positive pilot-scale metallurgical trials, the commercial picture becomes very clear.”
Cummins said the company had demonstrated it can produce high-quality, low-impurity concentrates, which he described as a significant de-risking step that is driving interest from end-users.
The maiden mineral resource estimate for both manganese and iron is scheduled for completion in September 2026. That estimate will feed into a scoping study targeted before year-end, which will provide the first formal look at the economic viability of a dual-commodity operation at Wandanya.
BCA shares traded flat at A$0.30, giving the company a market capitalisation of A$48.64 million.
The broader 9-kilometre corridor at Wandanya remains largely untested. The mineralisation is open to the south of the current drilling, with each extension adding tonnage potential to the project's resource base.
Black Canyon is focused on manganese and iron ore development in Western Australia's Gascoyne region.
