If you read the article that was posted on here from the West Business paper, management were quoted as saying profit will be between 60-80/t from current prices and at that time price was 160 or there about, so am very confident that this will be the costings so basically double what ever you have worked out. I mean the paper didnt just make this up and management are not in the game of lying just to make it sound good.
So as a quick figure monthly average will be around 155/t so that is what we can expect approximately for payment thereby giving a 55/t profit lower end and 75/t upper end.
