Ann: December 2023 Quarterly Report, page-36

It is obvious that you are right to a point.
The money spent at Bryah to install a $8m pebble crusher ended up just maintaining name plate tons through the plant.
So we come back to what is the perfect plant profile for the feed ahead of it.
That comes down to knowing what your putting through it for the next 10yrs other wise your throwing money at a best guess configuration that will probably be wrong.

So instead they have taken costs out of Milling sites as a start -that's the easy bit and quickest most sensible return on Capital investment upfront.
Their investigation on a Tuka expansion came in at $60m plus.
It then comes back to what Mill feed your dealing with.
A Chicken or Egg first scenario.

As the feed profile gets solidified the next step is fine tuning the plants,whether that's heavier crushing,finer grinding,residency etc.
Just as the enlarged NST started to prioritise feed to different configured mills to up yield and Mill through put with existing plant, we are seeing a planned channeling of feed to different plants initially.

I expect to see plant upgrades being finalised over the next year or so targeting improved yields and possibly more tons to match that expected feed profile.
Or they could pick up a few sites with softer more amenable ore to blend in in the shorter term to squeeze more through.
Or they could likely find it themselves with a bit more drilling far cheaper.
