Concentrate Circuit program successfully completed

Since the completion of the Pre-Feasibility Study (PFS) in mid-2018, COB has been advancing the metallurgical program for the Broken Hill (Thackaringa) Cobalt Project. COB is encouraged by the positive results achieved, when upscaling the quantity of material by 50x to the pilot trial.


  • Completed previously announced pilot-scale production of concentrate from 45 t (wet basis) of ore.
  • Achieved 90% recovery of cobalt to concentrate, confirming Pre-Feasibility Study results at 50x larger scale.
  • Consistent concentrate circuit performance (as measured by concentrate grade and cobalt recovery) for wide range of feed ore grades. This provides confidence to successfully treat as-mined ore with no ROM blending required.
