Wonmunna Project

The Pilbara region of Western Australia

Project Description

The Wonmunna Iron Ore Project is located 80km northwest of Newman and 365km south of Port Hedland – along the Great Northern Highway. The Project comprises one granted exploration license E47/1137 and three mining leases M47/1423, M47/1424 and M47/1425. The tenements are situated within the East Pilbara Shire within Vacant Crown Land.

Access to the Project is via the Great Northern Highway, which intersects the Project boundaries, providing easy access to the Project area.

Wonmunna comprises four primary deposits hosted by the Marra Mamba Iron Formation – namely, North Marra Mamba (NMM), Central Marra Mamba (CMM), South Marra Mamba (SMM) and East Marra Mamba.

The Marra Mamba Iron Formation is the basal member of the Hamersley Group in Western Australia and is host to major iron-ore deposits in its upper Mt Newman Member including the nearby Hope Downs (RIO JV), Area C (BHP JV) and West Angeles (RIO) operations.

The NMM, CMM and SMM deposits are contained within the three mining leases and form the basis for the project development plan for Wonmunna.

The EMM deposit and any other subsequent deposits found within exploration license E47/1137 provide good potential to extend the life and/or production rate of the Project.
