Snapshot	In Sept 2022, Strike (previous owner) completed a maiden shipment of 66,618 tonnes of high-grade lump hematite iron ore from Paulsens East Mine, but less than a week after the maiden shipment exports were suspended given market conditions. As at June 26, 2024, contractor mobilisation and resourcing are already well advanced. Paulsens East Mine is projected to produce 1.5 Mtpa of DSO hematite ore for export. Initial planning calls for mining operations to ramp up considerably across the first three months to achieve projected mining and processing targets. New camp facilities and site infrastructure will be developed to support site operations, with construction and operations requirements creating over 180 jobs within the local economy. Contractor will responsibility for all Management, Engineering, Drill & Blast, Operations and Crushing. Initial export will be undertaken through Utah Port, prior to transferring to the newly upgraded Port of Onslow.

Summary:

The Paulsens East tenement includes sediments of the Middle Proterozoic Wyloo Group which contain hematite mineralisation. The Wyloo Group rocks range from the continental Beasley River Quartzite to red beds of the Mt McGrath Formation that have been overlain by the shallow marine Duck Creek Dolomite.

The iron mineralisation found within the tenement occurs as a hematite conglomerate in the Mt McGrath Formation forming a prominent arcuate ridge up to 60 metres high, with cumulative average widths of ~6 metres and approximately 3,000 metres long. The conglomerate consists of hematite pebbles in a hematite rich matrix and cement. The conglomerate, when it is fully mineralised, is composed of hematite clasts in a hematite matrix. When the conglomerate is “unmineralised” (i.e. below economic cut-off grade) the clasts are composed chert and often Weeli Wolli BIF (a distinctive banded red chert alternating with a siliceous hematite BIF).

The Paulsens East iron ore deposit comprises three main bands of iron rich hematite conglomerate mappable as continuous bands along its three kilometre strike length. These bands were originally deposited in the Proterozoic and formed by erosion of mineralised bedrock and its subsequent reconstitution. During reconstitution, hematite pebbles were deposited and held together in hematite matrix along land and marine interface such that the high purity heavy hematite conglomerate bands occur interbedded with ferruginous quartzites and subordinate ferruginous clay.

The core of the deposit is generally very high grade and it is expected that sampling of blast holes and sharp colour contrast will assist greatly in grade control.

The Indicated Mineral Resource extends from the surface to 75 metres below the deepest drill intersection or the 150 metre RL (reduced level), whichever occurs first.
