Ann: Boda-Kaiser Scoping Study, page-10

costs are in line with what similar size projects. payback of 4 years for the 20Mt plant is very acceptable.

and they only use about 30% of the total resource for the current SS. rest of the resources will use bulk mining method and those studies will probably be funded from the cashflow.
basically the LOM will be over 30 years but ALK can't report it as the SS only covers about 30%.

and Boda2/3 zone where they found more high grade material (around hole 094) is not part of the total resource so there is more to be added to the plate.
