Your DTE value is correct. A nice little boost ((hopefully)) if you bought some at $0.12
= IGAS price x share conversion factor x exchange rate
= $0.99/share x 0.08117 igas/dte x 1.8 AUD/GBP
= $0.145/share
I'm no foreign exchange expert - Australian dollar falls our IGAS value goes up. Downside is that if IGAS sell or start producing the NSW assets they will get less $ in GBP. But I don't think the exchange rate is going to be critical. Price of gas/oil and the US exchange may be a greater driver.
