Let's try a valuation, page-2

Good figures- like crunching numbers for interests sake.
We've had predictions that Each Coldry Module would put out 275,000 tonne/ year. So a 2.2 mill tonne pa mine would be 8 plants. Mayby 9 if You wanted an extra for continuing target output and carrying out maintenance programmes.
So a 1.9 mill per year mine would require 7 Coldry Modules. Mayby 8 for maintenance/ continuity.
So 17 modules required x $15 mill each =$255 mill outlay.
I'm sure Construction would also have to incorporate Foundations, waste heat ducting, electrical supply and product Storage.
Perhaps a $265 mill outlay..,
