I think customers and Alcoa would have seen enough to be comfortable moving ahead however may need to do some final testing depending on the feedstock being used. If the Cadoux feedstock is being used globally given its 100-year reserve then it may be less of an issue however if they plan to use alternative feedstock (such as the one in the pilot plant run) in some plants then further testing will be required. Overall I don't have major concerns on this point as Alcoa wouldn't be signing the JV if they didn't think they could sell the product.
