Brockman said the mineral resource estimate incorporates the previously identified exploration targets at Sirius, almost all converted into mineral resources.
The company noted that no new exploration targets have been identified during the drilling programme or resource update.
Together with the previously revealed mineral resources for the Coondiner and Kalgan Creek Deposits, the total direct shipping ore mineral resources at the Ophthalmia project now stand at 305Mt, grading at 59.11% iron.

By GlobalDataThe company said it will also investigate the potential for a smaller, interim road-haulage operation, based on the high-grade mineralisation at Sirius.
Brockman’s hematite projects are situated in the Pilbara region, adjacent to the core tenements of Western Australia’s other major iron ore developers.
The company’s principal developments include the Ophthalmia project, the Marillana project and several other minor exploration projects in the area.
Brockman said that among all projects, the Marillana project is of the largest in scale with about 1.63 billion tonnes of hematite mineral resources.
