Ann: Annual Report to Shareholders, page-37

You sure have a strange way of asking for something- no matter! You’ve already been told by @presto & @tubber that to extract said PGM’s economically a mineral concentration needs to be identified - be it spinels, silicates or sulphides. For some reason Castro the CP has been unable to identify any minerals in which said PGM’s are hosted, therefore one can only assume either:
- Castro can’t identify sulphide mineralisation in core
- Castro can’t identify various spinels in core
- Any potential PGM mineralisation occurs as ionic substitution within silicate minerals (possibly Orthopyroxene or Olivine).
Until BBX can identify which mineral/s host PGM’s & what proportion of the core they represent, the “assays” presented are meaningless for establishing a JORC compliant MRE.
For example:
- Companies reporting Li2O% numbers with no mineralogical description knowing full well that unless the lithium is within a brine or Spodumene it currently is uneconomic to extract!
The same can be said for many chemical elements including PGM’s, Nickel, Aluminium, REO’s, Iron etc…
The “unaltered” **broic unit described by BBX would normally be considered far too fractionated (altered from primitive magmatic sources) to contain any sizeable concentrations of either Spinels, Sulphides, Olivines or Pyroxenes!
If that is the case - what exactly do they propose to mine & concentrate for metallurgical extraction?
