Ann: KOTH Final Feasibility Study delivers 2.4Moz reserve, page-8

You're right about running above nameplate capacity but I doubt it will be capable of 6 Mtpa. That rate requires expansion of other parts of the process. The 6Mtpa crusher has been purchased with the future in mind.

'design allowance made for future upgrades to the capacity of the grinding, leaching and elution components with minimal production interruption and low capital expense'

DCN plant has been running ~15-20% above nameplate fairly consistently. That was designed and built by GR Engineering who I would have thought will be in the box seat to build RED's also.

Reasonably large increase in AISC since the PFS but might be a fact of just bringing more deep material into the mine plan and extending the mine life. Gold price increase obviously helps offset that.
