"To get to AUD300m$ profit (200mm US$) you would need to get 100% of Sarawak smelting profit, and then keep the H1 run rate, and then double it (11 + 5 + 44 x 2 x 2)."

the calculation again, is wrong. Now u r claiming to be accurate. I am not.

the additional 33% increase isnt subject to the existing overhead.

lets take ur 44million figure. If u increased it by 33%, it would come up to 57million. Ps:this 44million figure isnt accurate either.

however, the big cost items r static costs.

ie: depreciation, finance cost, staff overhead. These r all accounted for in the first 75% of production. The margin from the additional 33% production increase flows to the bottomline.

lets say thats about 100,000 tonnes of product. If u have a 300usd gross margin most of that goes to the bottomline. So its a 30mil increase on the 44mil.
