I would not worry about delay @amertoo - IGO has a new CEO, Ivan, who has taken a bit of a battering from his former bosses at RIO - I say they were a bit cranky that he left and especially to IGO which is much more light and nimble than Rio.
So IMO Ivan will want to cover the Copper Wolf project before any decision is made.

Also it is probably a pretty complex task putting all the historical geology and mineral discovery which is known to medium depth (~600m), with the results of this one hole ~ 600m further deep.

I wont be surprised if we are waiting into 2024 before we get a sniff of whats happening. Lots might say 'that's not acceptable' but this project is potentially a major mine, requiring major exploration investment still, even though historical results are, frankly, exceptional.

Keep up with your DD, and just wait for the Gods of War to speak.
