valuation question, page-17

am new to key, but looking, as this thread is valuation. am asking for info
40mcuf /day value is around $800000k/day or around 280m $ p.a.
at 20% key is 60m$ p.a. for key.
i have no idea of taxes costs resource size capex on pipeline so im going to say key keep 30% npat.
thats $20m * p/e10 =200m$ / by say 120mshares = sp $1.60.
now i know im probably missing somethings so any better detail would be appreciated by key longtimers.

cheers
