Snapshot	The Paulsens East Mine consists of a ~3km long outcropping high-grade hematite ridge. In September 2022, Strike Resources Limited completed its first shipment of 66,618 tonnes of 62% Fe Paulsens East Lump DSO to China via Utah Point at Port Hedland. Although a key milestone, further shipments were paused due to market conditions and rising costs. On June 24, 2024, Terra Mining signed contracts to operate the mine on behalf of Miracle Iron Holdings Pty Ltd, assuming statutory on-site roles. New camp facilities and infrastructure will be developed to support operations. Paulsens East will produce DSO hematite ore for export, initially shipping through Utah Point before transitioning to the upgraded Port of Onslow once completed.

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.
