I've been doing some research and came across some figures in comparing AOH & CDU.
Please correct me if any are wrong.
CDU: approx $60M cash, 1Mt Cu. eq, production in 18 months
AOH: approx $65M cash, 1.3Mt Cu. eq, production in 6 months
AOH: reserve & DFS
CDU: no reserve & no DFS
AOH's costs: $1.4/lb
CDU's costs: well we don't know....
AOH EV of: $90m
CDU EV of: $400m
