I wasn't aware that a $50m guesstimate had been made. Thanks for that info.

My understanding is there should be significant interest due to the project having some big advantages over other pumped hydro projects (including those up the gulf in SA).

My baseline guess was a $20m price tag, but I can see a better result being possible. Probably not $100m, but yes $50m is probably not a silly guess. 

That is just my opinion, I have no inside information....just reasonable familiarity with the SA power market from being involved in another (non-mining) industry.
