Page 59 which shows Kami's place on the cost curve is what I"ve been searching for; the danger is future expansion from the big 3 Oz miners (BHP, Rio, Fortesque) on the left of the curve combined with less than expected demand will leave the higher cost producers high and dry. Still it looks like the mine will go ahead; potential producion of 16MT/yr at $100 a tonne would give about $38M to Altius after the royalty tax.
