It's hard to say because it all comes down to their assumptions with respect to the lithium price they can achieve.

I'm guessing that rather than provide a single figure, they'll give a range of estimates based on varying sale prices. Hopefully they'll also give estimates for different scenarios such as partial DSO sales, etc.

They're going to be conservative but I'd say that $800m would be on the low side. IMO that would be a worst case scenario.
