The Broken Hill Cobalt Project Resource
The Broken Hill Cobalt Project comprises three large tonnage cobalt deposits (Pyrite Hill, Big Hill & Railway) hosted by an extensive sequence of pyritic-quartz-albite gneiss of the Himalaya Formation. The deposits were the subject of an updated Mineral Resource estimate released in April 2019. The estimate reflected the culmination of a sustained exploration effort by COB (30,000m drilled from 2016) realising a 235% increase in resource tonnes and a 189% uplift in contained cobalt since COB issued its prospectus and became an independent company listed on the ASX.
