Progress Report

COB announces the successful installation and commissioning of its Broken Hill based Pilot Plant. Production of concentrate has been operating at nameplate 2 – 3 tonnes per day since the start of May.


  • Pilot Plant successfully installed and commissioned with all concentrate, leach and mixed hydroxide recovery circuits tested. Multiple Mixed Hydroxide Product (MHP) test runs have now been completed over the last four weeks under varying conditions.
  • COB is pleased to report all unit operations are currently operating and the plant is producing MHP. Shipment of samples will commence shortly, with over 30 global partners to receive Broken Hill Cobalt Project (BHCP) cobalt samples (total production from the Pilot Plant is expected to produce up to 150 kg of samples).
  • Pilot Plant production of BHCP feed material is expected to be completed during over the next 6 – 8 weeks. In parallel, COB expects technical and commercial discussions to begin.
  • Results from the Pilot Plant will be used to plan for the continuously operating Demonstration Plant.
