Some basic oil in place figures, page-91

200 bagger from here means A$14 per share or A$52 billion market cap. This would value our lease at US$184,000 per acre. To yeild this we would need many, many billions of recoverable oil bbls and development and extraction costs at world's best levels.

Putting aside any views on how plausible a scenario this is, the above numbers are just arithmetic extrapolations as getting that sort of acreage lease valuation means that a shed load would have been spent on appraising and proving the resource value. This shed load would certainly be funded via massive shareholder dilutions which in turn further raise the bar on what the SP would need to be to be a 200 bagger.
