I don't think sub-$1 is out of the question. At current oil prices Linc's process will barely break even, and the uncertainty over Teresa is hitting the market hard.
But if it does go sub-1 it will only be temporary. OPEC has just slashed production to try and get the price up, and if they can settle Teresa they will have money in the bank. It might not be enough to completely fund Linc going forward, but whatever they can get will mean less funding they have to seek elsewhere.
Of course, if the Xinwen deal falls through, sub-1 is a distinct possibility. Coking coal prices are going to come down in line with iron ore prices, probably to 50% of what they are now, and that will wipe half the value off what's in the ground at Teresa, and since the coal there has a rather poor strip ratio that will hit the profit margin of that coal far more than 50%.
