jorc code, page-3

Just in case you are not aware of a few key clauses:

Clause 14 Appendix 5A Page 9

A company must disclose all relevant information concerning Exploration Results, Mineral Resources or Ore Reserves that could materially influence the economic value of those Exploration Results, Mineral Resources or Ore Reserves to the company. A company must promptly report any material changes in its Mineral Resources or Ore Reserves

Of course, one can argue about the definition of prompt, but I think any rational investor can see that CDU are long overdue!
