On 31 October 2024, Coolabah Metals Limited announced that Broken Hill Mines Pty Ltd (BHM), a company it is in the process of acquiring, had completed the acquisition of the Rasp Mine and associated assets. This acquisition was achieved through BHM’s purchase of 100% of the issued share capital in Broken Hill Operations Pty Ltd (BHOPL) from CBH Resources Limited, a wholly owned subsidiary of Toho Zinc Ltd.

During the Half Year Ended 31 December 2024, Coolabah's principal activity was the progression of its acquisition of BHM. Upon completion of this transaction, Coolabah Metals will be reinstated as a minerals producer.

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.
