Dott its nickle and dime on 22kt ,but the trial was done with a view to sending much larger tonnages - some have suggested numbers around 1mt p/a maybe more so the recoverie rates becomes extremely important to gauge the economic viability of such a decision.

In a toll processing situation the economic risk is placed on the miners balance sheet , so copper % grade , recovery rates and transport costs become all important - If Glencore were buying the ore then the risks shift to their balance sheet - but after the Exco $175m purchase proved to be a not so great investment I would expect ( but could be wrong ) only a toll processing and offtake for buying the concentrate proposal would be in the offing.
