You really have to think about Walford Creek in two ways. I'll go top down.
The big picture is 25km of Fish River Fault 'structure'.
Zoom in and you have the 'Global Resource' at approx 4km of the 22km of the strike. It's a large poly-metal deposit. Copper - Zinc - Cobalt - Lead - Silver
This is a huge deposit, that would have very high CAPEX to get off the ground. The roasting scoping study looked at mining the whole 4km via open pits. Big tonnage and long life. This is a whole different ball game to the proposed mining of the 'Vardy' zone.
Vardy is a high grade, shallow part of the deposit, approx 1km long and representing approx 9% of the resource. This is the what the pending BFS relates to. It is low (ish) capex and a much simpler proposition. This is a Copper - Cobalt - Zinc and Silver mine.
This graph shows you the 2 ideas and where they sit vs other Australian projects.
