I found this quote in the announcement to ASX titled 'Twin Hills Silver Project - Development Update'. The update is dated 16 Feb 2011 and states:
"An economic review of the Twin Hills Project was completed last Quarter, which confirmed that the operation is well placed to generate strong operating margins based on a forecast annual processing rate of 1Mtpa from the Twin Hills resource. At this production rate, the operation would generate average annual silver production of 1.5-2.0Moz (with fluctuations from year to year typical of a heap leach project) and have forecast unit cash operating costs of approximately A$13.50/oz."
I hope this helps.
