the number that MG and SLX have had in their presentation for the $90m Royalty was said to be the equivalent of 8MSWU.
This has been an area that I am unclear in, as he also said (in the AGM) that the $90m royalty is what they would expect to come from "the two grey areas" - which was the tails processes PLUS 6 MSWU of LEU production.
This is what I was getting at in the AGM post I made when I backed into that the known revenue and profit that should come from tails;
If tails plus 6MSWU = $90m USD royalty then
Total Revenue = $1.2bn
Tails Revenue = 5m lbs UF6 = $600m
Tails Cost = $150m
Tails Profit = $450m

if Tails revenue is $600m USD of the $1.2bn Total Revenue then it seems to me the 6MSWU revenue is undercooked though at $600m as well.
Why would that be the case? I haven't been able to answer that since the AGM.
