If CDU do produce a native copper product, a smelter, most likely a smaller secondary smelter will take the native copper, but they will still pay a discount to LME Cu, as the native copper will still have to be smelted/refined to meet the LME contract specifications.

I think it is potentially misleading to indicate that a 'premium' will be paid for a native copper concentrate.

Ultimately, one can estimate the potential income to CDU from the native copper/DSO mineralised material (to be called ore it has to be economically viable to mine, and this is will be supported by a positive feasibility study), but to date the public disclosure of CDU has not yet allowed this to be done - contrast with SFR.
