Why did I say "Whoa!!" ?
I was responding to Hawker074 post...

Where he posits the case for basing the upcoming P2 upgrade on a larger body of coal than simply the main seam.
"If the PCD is in Q1,2,3 does that allow the whole 239 Mt to be included in the upgrade, as the coal at the 3 sections share the same particulars?"
If his observation is correct that would change my 2P estimate (refer https://hotcopper.com.au/threads/what-is-it-really-worth.4660171/page-91?post_id=37686987) as follows...
My previous estimate for 2P...
407 Million Tonnes X 22.8% X 65% Geo Risk X 82% Process Risk and 16.5 GJ syngas per tonne of coal = 816 Pjoules
New estimate if Hawke074 is correct...
239 Million Tonnes X 60% X 65% Geo Risk X 82% Process Risk and 16.5 GJ syngas per tonne of coal = 1,261 Pjoules
Here's hoping his deduction is correct.
