[Ferro-Alloys.com] Drilling Resumes at the High-Grade Wandanya Mn and Fe Discovery

• The third drill program is underway at the Wandanya Project to infill and extend the high-grade manganese and iron mineralisation discovery that has been mapped over 3km of strike.

• The Wandanya hydrothermal manganese and iron discovery represents a new exploration model on the eastern margin of the Oakover Basin where Phase 2 drilling results1 returned consistent shallow, thick and high-grade manganese intersections over at least a 2km strike, including:

o 6m @ 35.0% Mn from surface including 3m @ 42.1% Mn from 3m (WDRC095)

o 8m @ 28.5% Mn from surface including 3m @ 43.2% Mn from 4m (WDRC097)

o 6m @ 29.2% Mn from surface including 3m @ 43.1% Mn from 3m (WDRC107)

o 5m @ 29.3% Mn from surface including 2m @ 45.8% Mn from 3m (WDRC113)

• The remaining 47 drillholes from the Phase 2 drill program targeting high-grade iron and manganese are expected to be finalised by the end of August 2025.

• Assay results from the Phase 3 Reverse Circulation (RC) drill program are expected during October. A diamond core drill program is also planned to obtain core samples for further metallurgical testwork to progress beneficiation.

Australian manganese explorer and developer, Black Canyon Limited (Black Canyon or the Company) (ASX: BCA) is pleased to announce that Phase 3 RC drilling has commenced on the Wandanya Project (BCA 100%) to extend the current drill coverage to the north and undertake infill drilling to test the entire 3km of mapped high-grade manganese and iron mineralisation.

Black Canyon’s Managing Director Brendan Cummins said:

“We are excited to resume drilling at Wandanya, building on the outstanding results from our initial programs which confirmed shallow, high-grade manganese and iron intervals across a broad strike length.

“Phase 3 drilling will test the full 3km of mapped manganese and iron mineralisation, including infill and step-out holes designed to both expand and define the mineralisation footprint at Wandanya.

“The remarkable geological continuity observed to date combined with the scale of outcropping and shallow mineralisation with proximity to existing infrastructure, reinforces our belief that Wandanya represents a significant manganese discovery in a highly underexplored part of the Oakover Basin.

“With assays from the remaining Phase 2 holes expected by the end of August and Phase 3 results expected in October, we look forward to maintaining strong momentum through the remainder of 2025 as we strive to unlock the full potential of the Wandanya manganese and iron discovery.”

RC drilling the Wandanya High-Grade Mineralisation (BCA 100%)

The phase three RC drill program will comprise approximately 150 holes for 3,500m to extend the current drill coverage to the north and infill the current drill line to test the entire 3km of mapped manganese and iron mineralisation and cross strike width between 400m and 700m. The drill line spacing is variable between 200m and up to 300m with the planned hole centres on drill lines approximately 40m apart.

The drill program is expected to take 3 weeks to complete with assay results expected to be received through October and November.
