OZ Minerals Testwork Agreement

COB has successfully developed a processing technology for recovering cobalt from pyrite at the Broken Hill Cobalt Project. The 2018 PFS reported cobalt recoveries of 85–86% from ore to final cobalt sulphate product (ASX announcement 4 July 2018).


  • Cobalt Blue Holdings Limited (ASX:COB) has entered into a testwork co-operation agreement with OZ Minerals Limited (ASX:OZL).
  • The testwork will evaluate the application of COB technology to recover cobalt, copper and gold from a pyrite concentrate. A key aim will be to assess if a high purity cobalt sulphate can be produced from the concentrate.
  • OZL will provide COB with a 10–15 kg sample of pyrite concentrate.
