These estimates reflect the costs entailed in producing a concentrate for sale or toll
treatment only. Although further downstream pyrometallurgical or hydrometallurgical
treatment of concentrates has not been assessed in the current study, additional
treatment will almost certainly be evaluated in subsequent, more detailed, studies.
Future work will also require testing the MF2 process flowsheet and additional
downstream pyrometallurgical and hydrometallurgical concentrate treatments as
described in Section 26.0 in this report. The estimated cost of the above test work is
approximately US$400,000.
25.4 I NFRASTRUCTURE
Additional studies for the locations of the TMF and the process plant area will be
required. Some geotechical and detailed topographical surveys will be required in
order to complete these studies.
A trade-off study has been commissioned to compare power generation diesel fuel
versus LNG for the Project.
