ASX Today, page-8428

I think there's something wrong with your calc but not sure where, 'would make it simpler, say 350k no vol increase x 40 years = 14mt x usd2,24o = USD31.36 billion revenue
Say costs all inclusive is usd345 per pfs = usd4.83 billion
Therefore profit is usd26.5 billion

nearly $1 billion profit p.a. for SC6 alone.
Add Downstream and i think it's mind boggling. if there's a sustained price of SC6, we can just produce sc6 until 2030 and not need to expedite the integration as one would like otherwise.

we don't get to mine all the 156mt there's reserves vs inventory, ie not all of it is included only reserves when they make calculations, i'd just go with LOM x annual prodn x price as above

cheers
