only a fool would sell icn shares., page-5

There is always a chance of any exploration well not going as planned.

but, I f I had the cash, I would buy more ICN shares, not just because of Halifax-1 but ICNs holdings in the Gippsland basin also.

APT855 has always been held buy all Gas exploration companies , is the sweet spot of the Nappamerri trough in the cooper basin. It was a most prized tenement for all, and ICN won it.
Doing my own research , I believe Halifax-1 will be a combination of the Moonba 191 well and Moonta-1 gas flows. In other words a commercial well.
