Norseman Mine comprises three mines, the OK Underground Mine, the Scotia Open Pit and the Green Lantern Open Pit and processing facility.
Construction at Norseman was completed during the first half of the year, and the new processing plant has been in operation since November 2022. Unfortunately, a number of operational issues within the project have hindered the ramp up to full production. |

Pantoro Limited has a 100% interest in the Norseman Project.
On 13 February 2023, Pantoro announced an agreed merger with Tulla Resources Plc, the then 50% partner at Norseman. The merger was completed in late June 2023, with Tulla Shareholders receiving Pantoro shares as consideration.

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:
The mining was underway in open pits at the Scotia Mining Centre and underground at OK Mine for the entire period.
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.
Open Pit Mining
All open pit mining has been undertaken at the Scotia Mining Centre since the recommencement of operations in April 2022. There are two large open pits being mined including the Scotia open pit, which is a cut back of two historical open pits, and the Green Lantern open pit which was a new discovery by Pantoro during the exploration phase.
Scotia (South Mining Centre)
Scotia open pit mining centre is staged as three contiguous pits (North, Central and South). The final pit shell is 1,150 metres long and e ........
