Ann: Rio to Invest $40.4m to Become a 15% Strategic Investor, page-23

Not necessarily - only if you missed the boat and are hoping to get in cheap - with PFS due in 6 weeks - RIO could exercise the additional top up to 19.9% at any time - in fact it appears they want the lot with that bottom dot paragraph - hands off is what that suggests to any other potential investors - third parties of anything SVM.
40 million aud for 15% - another what18.5 million aud for next 5% to max out at 19.9% - would they pay for the remaining 80% to hold the worlds largest rutile resource - still untapped with plenty of upside and graphite of the battery grade type required for EV's as a sideshow. Clear they certainly want to keep the Chinese out for whom invest heavily on the African continent for such assets of scale. He's the master of discovery and extracting maximum value our chairman. And with Sprott involved - I think this will roll quickly - not quiet in Wa1 fashion from pennies to $6 on a niobium discovery in WA. Just feel RIO will scuttle that possibility but it certainly should finally to real value after many, many years.
Don't forget the other very large graphite assets Malingunde on well advanced and another the name escapes me - as RIO stated - hands off any SVM other assets.
