Patterson's estimated it would cost $10m to drill out Bombora last September. We have that cash in the bank. In addition, 50% of drilling is paid for with shares to Ausdrill. The higher the sp goes, the less shares we have to issue (which btw there should be a 3B out soon for last month's bill)
Admin costs are low with 80% of cash going into the ground.
EDIT: I have no doubt Tom is a good manager. He has stated before that nothing is off the table but i seriously doubt that anything will happen before the maiden JORC event in December.
