Couple comments which might help.
Flowsheets,... have stated many times that in mining processing flowsheets are always a "work in progress" for better optimization up until mine build for most if not all mining companies.
Second, they are not going to spell out every detail of the process in a NR update, that is used to give you the headlines and then comments by participants working on the process. You'll see more in the 80 page Technical Report for the PEA, within 45 days of the PEA release. (they may be patenting the process as mentioned from AGM, as just another reason for not disclosing all information)
The PEA will spell out all costs, including those for Processing.
Basically, all comes down to trusting AE and Management views, that everything is going well until we see the factual information when the PEA is released, versus the bashers trying to poke holes in every disclosure. It was first "Sulfer", then "Crystall Size", now they target "Flowsheet" to create doubt that is never substantiated on their part.
Cheers, Mark
