Mount Seabrook Talc Mine

Mt Seabrook is situated within the Peak Hill Mineral Field, Mid-West Region of Western Australia — a semi-arid, low-relief terrain characterised by lateritic plains and isolated rocky outcrops. The subdued topography facilitates bulk earthmoving operations, minimising complex cut-and-fill requirements. However, shallow regolith profiles demand precise geotechnical assessment prior to pit expansion. Seasonal aridity and dust suppression remain critical site management variables impacting haul road integrity and equipment availability across the operation.

Fully acquired by IMI Fabi in 2011 following a staged 50% entry in 1996, Mt Seabrook operates as a dedicated industrial talc supply asset. Continuous 24/7 operational cycles drive high diesel consumption across mobile fleet assets — loaders, haul trucks, and ancillary equipment. Dependency on reliable power infrastructure, including dedicated substation capacity, is non-negotiable for processing continuity. The site feeds IMI Fabi's global talc supply chain, serving industrial and specialty mineral markets requiring consistent high-purity talc grades.

Talc extraction at Mt Seabrook involves selective open-cut mining with controlled blasting and mechanical ripping of soft mineralised zones. Post-extraction material handling relies on conveyor systems linking the pit face to primary crushing and beneficiation circuits. Efficient conveyor routing is critical to minimise haulage costs across the flat terrain. Processing infrastructure includes grinding and classification circuits to achieve target particle size distribution specifications demanded by downstream industrial customers in plastics, ceramics, and coatings sectors.

Operating within Western Australia's regulatory framework mandates strict Heritage compliance under the Aboriginal Heritage Act, requiring systematic survey and clearance protocols prior to any ground disturbance. B2B procurement strategies increasingly prioritise engagement with Aboriginal-owned enterprises for civil works, environmental monitoring, and site services — aligning with Reconciliation Action Plan commitments. Rehabilitation planning and progressive land restoration are embedded in the operational lifecycle, supporting IMI Fabi's broader ESG reporting obligations to global industrial clients and institutional stakeholders.
