Ann: 121 Mining Investment Presentation, page-19

Cobalt is most likely a total ramp by Tony. You only need a very small amount of Co in an assay to label things as Ni-Cu-Co. The presentation never identified any level of Co and nor has any other announcement, as others have noted. If you want to wind things up then Co is a good lever.
No, of course it will not be untrue - the only thing lacking is the amount of Co.
If we get an announcement soon identifying appreciable levels of Co, then I am prepared to eat my words but the previously announced results had no reference to Co and why was there no quantative statement to it in the presentation?
