Summary:

Total Koolan Island Mineral Resources and Ore Reserves comprising the Main, Acacia East and Mangrove Deposits.

Koolan Island, Main Deposit
The mineralised zone is an overturned enriched haematitic sandstone horizon within the Yampi Sandstone Member unconformably overlying the Elgee Siltstone. It is between 12 and 30 metres thick, and dips 55 to 80o to the south.

Dimensions
The Main deposit mineralisation is approximately 2,000 m in length and is currently modelled to approximately 215 m in depth below mean sea level. Mineralisation continues and extends beyond this depth however further infill drilling is required to define this area with confidence. The resource is open at depth.

The Acacia East mineralisation is approximately 1,500m in length and is modelled to approximately 300 m in depth.

Koolan Island, Mangrove Deposit
