Ann: Rio to Invest $40.4m to Become a 15% Strategic Investor, page-76

I would certainly want September as advised "completion of PFS by end of this current quarter" - It would be excellent for a company to deliver on time guidance that all to often is missed. I have an inkling with RIO team on the job and their experience and expertise that could be seen as very advantageous - yet with changes it takes time to review and implement them in the PFS - along with the important tech there is always much more - initial production guidance a key one for example - for me the RIO'S and such are only interested in BIG as confirmed with their current mineral sands operations on their website - scale is cost effective - sure more CAPEX but we will likely get an insight to the project finance on the PFS production guidance.

PFS all important but just one piece of many key progressive milestones coming our way.
