Broken Hill global cobalt province., page-535

Australia.“Australia has increased its hard rock lithium production immensely in just a matter of two or three years. We can respond; it doesn’t worry me at all. Same with graphite. We haven’t really seriously looked for graphite. We’ll fix that. Cobalt is an issue, particularly with mining in the Democratic Republic of Congo, but we can we find 20 times more cobalt, not a problem geologically.“There are cobaltian pyrite deposits sitting at the surface all through the Curnamona Block in Australia. Increasingly, cobalt is being recovered as a byproduct of nickel laterite mining.” QUOTE
COB at Broken Hill sits within the Curnamona Block as well as HAV and CCZ . The Broken Hill Province will make history one day in the global cobalt supply market IMO
