I am expecting the CAPEX number to be well above $1B when the DFS comes out. SNC Lavalin have a habit of engineering very expensive HPAL plants. I have heard figures north of $1.2B. For example the Taganito operation in the Philippines is a little larger than Syerston. It's capital cost was apparently $1.7B without an acid plant.

Syerston will have a large acid plant. I would not believe the hype about their Clean IX process being cheaper than conventional processing. The DFS will be the first time anyone independent will have looked over what was "internal" costing for the PFS.

The cheap autoclaves will help a little, but there is a lot of infrastructure to develop from scratch in what is basically a rural farming community. If I was Sam Riggall at the moment, I would be nervous.
