Summary:

The project area lies at the southern extent of the Norseman - Wiluna Greenstone Belt of the Eastern Goldfields Province of the Yilgarn Block, Western Australia. The regional geology of the Norseman area has been subdivided into four formations being the Penneshaw Formation, Noganyer Formation, Woolyeenyer Formation and the Mt Kirk Formation.

The oldest unit is the Penneshaw Formation which has been dated at 2938±10 Ma (U-Pb zircon, (Hill et al., 1992). The western part of this unit is dominated by amphibolite with minor sediment and felsic rocks, whereas the eastern part comprises intercalated amphibolite and highly deformed felsic rocks.

The overlying Noganyer Formation consists of sediment iron formation (jaspilite), siltstone and sandstone, and minor carbonaceous shale.

Overlying the Noganyer Formation with a conformable or gently unconformable contact is the Woolyeenyer Formation. The Woolyeenyer Formation is dominated by mafic volcanic rocks with minor conformable ultramafic units and sediment bands. These rocks are intruded by mafic dykes with a dominant northeast to northwest trend that are interpreted to be syn-volcanic. The Woolyeenyer Formation is regarded as unconformably overlain by sedimentary and felsicvolcanic to volcaniclastic rocks of the Mt Kirk Formation that have been intruded by thick, differentiated mafic sills. The contact between these units is marked by the regionally extensive Abbottshall Chert comprising sili ........

Summary:

Life of Mine Plan
The Phase One DFS Life of Mine (LOM) mines and processes 5.9 Mt of ore of which 4.8 Mt is Ore Reserve and 1.1 Mt is Inferred Mineral Resources. 25% of the total Ore Reserve remains unmined and available for future production at the end of the Phase One DFS LOM.The Inferred Mineral Resources have had modifying factors applied in the same manner as the Ore Reserve. There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised.

Mining Schedule
Pantoro has utilised a very conservative approach to mine scheduling for the purposes of the DFS. All ore mined is assumed to be stockpiled and processed equally with no discrimination between high grade and low grade ore. In practice, higher grade ore will be transported to the ROM with low grade ore stockpiled at the mine until required for processing.As additional ore sources are added in subsequent stages of Mineral Resource and Ore Reserve definition, new high grade ore sources will replace low grade stocks assumed to be mined.

Mine Design
The large open pits to be excavated at Scotia, Gladstone, and Cobbler have been designed in stages to maximise open pit ore feed throughout the project life. Other open pits have been designed to be excavated in a single stage.
