Johno,

They need diffrent drill rigs on site at Kare to go deeper and the cost to do that I could not see a 750 metere core hole, properly completed, coming in at much less than A$200,000 each IMO

So 2x min = 400K in PNG
IDC would have to weigh it up cost wise they may already have.

What would you do to get the mine up and running
might answer your question
