Black Canyon confirms Australia's next major greenfield manganese resource
ASX-listed Black Canyon has positioned the Wandanya deposit, in Western Australia, among the most significant recent greenfield manganese discoveries in the country with a maiden mineral resource estimate (MRE) of 23.6-million tonnes grading 25.8%.
The MRE defines a shallow, high-confidence resource that includes 12.5-million tonnes of iron-ore grading 54.9%.
More than 90% of the manganese resource and 100% of the iron resource are in the measured and indicated categories.
"Wandanya demonstrates exceptional scale and grade quality when benchmarked against Australian manganese peers. The deposit compares favourably to historical Tier 1 developments and features outcropping, shallow mineralisation over a 3.4 km strike length," says MD Brendan Cummins.
He adds that Wandanya has meaningful direct ship ore potential for both manganese and iron-ore.
Pilot-scale metallurgical testwork using simple dense media separation has upgraded manganese feeds up to 41% grades, with 80% recovery rates. Iron drop tests also generated a premium 74% lump product grading 59.7% iron.
Australia currently has two operating manganese mines, making new high-grade discoveries highly valuable.
Black Canyon aims to complete a scoping study on Wandanya, including preliminary economics, dual-commodity development pathways and direct shipping potential, by December.
