cash cost, page-2

$383/oz was estimated as LOM average in the scoping study based on a pit down to 100ms deep. This excluded royalties. A figure of around $500/oz was given including royalties and “overheads”.
However the grade is now much higher and recoveries are higher, offset partially by a smaller plant. Also Golden Hind was not yet discovered at the time of the trial mine and its cash costs will be much lower than for the greater Old Pirate resource thanks to much higher grade, wider ore body and shallower deposit (higher grade and much lower strip ratio).
I think $500 LOM ave including royalties should be a safe assumption although it should be lower in the early years with mining near surface.

Ceck out the scoping study results in 2012 for a rough idea.
