quarterly ann, page-37

Hi Plough, They have said that Aluminium oxide component is 30-40% of the total - back of the envelope stuff but if they toll treat a tonne of slag for $300 a tonne and then sell the resultant al80 for say $40-$50 per tonne ( this has been bandied about here as the initial contract amount - not confirmed by managment tho) -its extra revenue. Say $45 x 35% = $15.75 per tonne of slag.

Percentage? well if they hope to get $315.75 all up and can't sell the Al80 then its 5% less income.

Of course if they manage to get double that amount for the Al80 - or maybe they always wanted/counted on getting more? then perhaps a bigger impact.

But you can see why its not a company breaker for us as the tolling amount is the elephant in the room - and that is principally generated from the Aluminium recovered.
