Ann: Nifty Copper Project Restart Study, page-18

Nice post@Da12kl0rd. Just a question. Of the examples here it seems several of them are producing Cu concentrate. Of these how many are producing copper plate grade A 99.99% purity? Or if producing just copper cathode what grade is expected?
Points being if producing concentrate, they will be selling to the Chinese smelter overlords at a feeble price. So they are a price taker not a price maker.
We know these smelters demand discounts and increase smelting costs as seen last year.

This point is important as CYM has quoted copper figure prices but we know full well that LME Grade A 99.99% Cu plate attracts a price premium above the LME copper price. So CYM could attract up to an extra $3.5m income per year above forecast revenue.

Nobody is doing that with concentrate.
