SnapshotThe operations at the Rasp Mine include underground mining operations, a processing plant producing zinc and lead concentrates.

Broken Hill Operations Pty Ltd. is seeking to modify the Rasp Mine Project Approval to allow for the co-placement of tailings with excess waste rock from underground mining into Kintore Pit as Tailings Storage Facility 3 (TSF3) critical to the continuation of mining operation.

The Life of Mine (LoM) post 2026 would continue to develop the Centenary Mineralisation and extend the Main Lode to all mining blocks. A modification application would be submitted to extend mining operations past 2026 and to include mining areas that are not within the current PA.

Deposit type

  • Sedimentary

Summary:

The ore deposits at RASP Mine are hosted by a sequence of Proterozoic meta-sedimentary rocks.

Mining operations are primarily focused on the extraction of the Western Mineralisation (WM), combined with lesser quantities of high grade remnants of 2 and 3 Lens, and Zinc Lodes that are associated with the original Main Lode.

The original unmined WM contained a global resource of approximately 15Mt at a combined PbZn grade of 6.0%. However, mining operations are focused on extraction of areas of higher grade material.

The WM extends from approximately 100m below the surface to a depth of near 900m, where the deposit terminates against the Globe Vauxhall Shear. Mineralisation identified below this structure is associated with the Centenary Deposit which still remains open at depth.
