Key Highlights

  • Drilling north of the maiden Mineral Resource has delineated iron mineralisation over 1.8 km of strike.
  • Manganese is often associated with the iron zones over 1 km of strike, with intervals up to 28.9% Mn.
  • The best iron intersection is 6 metres at 56.5% Fe from 28 metres, including 3 metres at 61.3% Fe.
  • The Wandanya Scoping Study is progressing and is due for completion in December 2026.

Black Canyon Limited (ASX:BCA) has reported drilling results from north of its Wandanya maiden Mineral Resource estimate in Western Australia, in an announcement dated 4 November 2026. The company says the drilling has delineated iron mineralisation across 1.8 kilometres of strike, with manganese associated over 1 kilometre.

Iron Intersections

Drill hole WDRC1044 returned 6 metres at 56.5% Fe from 28 metres, including 3 metres at 61.3% Fe from 31 metres. Other notable iron intervals include 5 metres at 58.1% Fe from 26 metres in WDRC1032 and 4 metres at 58.8% Fe from 25 metres in WDRC1015.

Several further intervals, including 4 metres at 57.8% Fe in WDRC1039 and 4 metres at 57.5% Fe in WDRC1025, were also reported. The company presents these results as evidence of consistent mineralised zones north of the current resource.

The iron intervals come from the northern extension zone, and the company uses them to show that mineralisation continues over a strike length of 1.8 kilometres. The wide spacing of the drill holes means the intervals help identify zones rather than estimate grade across a block.

Manganese Zones

Manganese intervals include 4 metres at 24.7% Mn from 39 metres, with 2 metres at 28.9% Mn from 40 metres, in WDRC1037. Hole WDRC1036 returned 3 metres at 27.4% Mn from 25 metres.

The company notes that several cross-sections remain open both up-dip and down-dip. It attributes this to the wide spacing of the drilling pattern, which leaves the boundaries of the mineralised zones undefined.

Manganese is often associated with the iron zones and is reported over 1 kilometre of strike. The combined iron and manganese data are relevant to how the deposit could be defined, although the release does not provide a new mineralised envelope or a revised estimate.

Geophysics and Study Timing

A detailed gravity survey covering 38 square kilometres has been completed, and several shallow and deeper anomalies have been tested by drilling. The Western Australian Government Exploration Incentive Scheme co-funded the survey.

The Wandanya Scoping Study is progressing and is due for completion in December 2026. The announcement does not give a revised resource estimate, which would be needed to confirm the drilling results as resource growth.

The Wandanya Scoping Study is due for completion in December 2026, and the current drilling data will feed into that work. The gravity survey covers 38 square kilometres and was co-funded through a Western Australian government scheme.

Sampling and Reporting Standards

The iron and manganese results are reported as downhole intervals with weighted grades, and the company specifies the holes for each interval. The release notes that intervals are identified by hole number and depth, which allows readers to trace the results to the program. The announcement describes the drill pattern as wide, and it does not present a grade-tonnage relationship for the new zones. These elements will be addressed through the Scoping Study and any later resource update.

Final Word

The results indicate that iron and manganese mineralisation extends north of the current resource, but the drilling is widely spaced and the company has not released a revised estimate. Mineralised boundaries remain open in several sections. The December scoping study is the next scheduled update that will set out the project's technical and economic parameters.
