Yes, if all of them are 100% crystalline, then it can easily seperate by crushing into powder than use magnetic to seperate them.

if they aren't 100% crystalline, then it will require wet process which cost massive $$$ to build.

Stage 1: they can get 4.1mt DSO from 69mt crystalline resource. those 4.1mt DSO should last 2 years.

of course, they say they will try explore Wilcherry Hill 600mt for more DSO quality ore in future.

Stage 2: they talk about wet process .. I know there aren't any Magnatite project that cost less than 1 billion.

I think they won't wait for 4 years to start Stage 2, they may start feassible study for Stage 2 in next year etc
