I was thinking about this a bit more on the weekend eshmun. Not sure if you are talking about long term or the upcoming reserve update with your estimates. I doubt they will get near 2Moz in the upcoming update because you have included a lot of inferred material. They can't bring that straight into reserves form the resource update a few months ago.
Cameron Well only has 120koz in indicated so I think the maiden reserve is likely to be 100koz or less.
The Westralia reserve addition is a bit unclear. The M+I resources only increased by 9% since the previous estimate in 2016. Total M+I is 989koz of which 492koz is existing reserves. So potential addition is a maximum of 500koz from Westralia.
Not sure if there has been significantly more work around converting the deeper resources into reserves. They had the required drilling density but conversion would probably be more around the modifying factors (geotechnical would be important I think).
