Wonmunna ore is blend with Iron Valley and the proposed Lamb Creek and Wedge mines creating Utah Point Hub.
Mineral Resources Limited (MIN) operates the mine entirely at its cost and purchases Iron Valley product from BCI Minerals Ltd. at a price linked to MIN’s realised sale price. BCI retains ownership of the tenements and certain statutory obligations, including payment of royalties. |

Deposit Type
- Detrital Iron (DID)
- Banded iron formation
Summary:
Mineralisation within the Iron Valley deposit occurs as outcropping and buried Banded Iron Deposit (“BID”) and Detrital mineralisation (“DID”). Outcropping geology in the project is the Dales Gorge, Whaleback Shale and Joffre Members of the Brockman Iron Formation which host the BID mineralisation (predominantly in the Joffre member). Incised into this bedrock geology are deposits of DID mineralisation.
The Iron Valley deposit extends approximately 6 km along a strike of 030°. Width varies from 50m to over 600m. Thickness varies from <15m to >120m.
Summary:
Current and planned mining of the resource is by use of conventional open pit methods. The current primary mine production fleet comprises 1x Hitachi EX3600 excavator, Komatsu HD1500 (150t capacity) dump trucks and Caterpillar 992 Front End Loaders or similar equivalents.
Mine designs comprise detailed pit designs for the Life-of-Mine. Operational waste dump and stockpile designs are in place with conceptual designs for the later phases of waste dump expansion.
The overall slopes vary from 36° to 39° based on geotechnical studies.
Existing infrastructure in place supports current operational requirements with available capacity over 35 Mtpa (wet) total mining movement.
