No one is going to lend EXU $120 million without some serious cash put in by the shareholders, but they might lend $40 million to develop Mace. The cashflow from Mace could be used to fund the development of Tampia (a 1/2 approach). I don't know if this is viable or not, but it is a possibility.
To answer your question the perpetually ignored EGA looks like it will be going into production 2019 on debt alone. EGA is a very unusual company though so I don't think it has much relevance for EXU.
