RE:RE:$10.5 B US @ $4 copper.. Just for Kamoa-Kakula- 2nd phaseIn US dollars, only accounts for K&K......not WF or Platreef or Kipushi and copper is likely to head much higher before it plateaus. I'll bet we'll be fast tracking towards phases 3 & 4 as well. The pay back period for the initial development was 2.5 yrs at $3 copper . That time frame just got significantly shortened.
