The IGO work has been methodical. The geo team there is definitely no stranger to vms so it knows what it is doing.

I get the impression from the last ann that it has realised that there is a much bigger field than Neptune to explore.

I don't know if you know much about the Bryah Basin and the Narracoota Volcanics/Formation, Karalundi Formation and the Ravelstone Formation, but it's those 3 formations that are the main key to VHMS exploration in the BB. ALY/IGO has a fair bit of them. The other main players are RNI and SFR by itself and also with TLM. To fully get a handle on these formations' significance then you will have to read a lot I'm afraid.
