Ann: PFS Results - Bidaminna Mineral Sands Project, page-3

It says it in the document. Majority cash and a combination of debt and equity. Once we get closer to the time they will likely assess where the SP is at when determining equity. Problem I see is if they go SPP route the Chinese players will likely get their allocation in full meanwhile shorting the price to edge out retail. Then when it comes to the next spill vote we will lose. So Image may need to play it smart here, get atlas done, get some cash together then work out a capex model where they move the equipment again for this.
It's not ideal and if predatory behaviours to drive SP down during a CR weren't allowed then it would be a non issue as most shareholders would gladly pitch in extra.
The one thing that could turn it around completely is if they find a cornerstone investor to come in a private placement. That would likely cause some whingeing to begin with but ultimately work out better for shareholders if they consider the strategic games being played.
