Ann: MOU with Noble Group to Facilitate Monetising Stockpiles, page-47

Hi bullrush90
This is very dependent on raw ore grade and place of concentrate processing. Some of the stockpiles have had samples of between 10-18%. If you stuck with the 3.3% grade the JORC resource is at now for a feed grade, allowing for 90% recovery would mean processing 1.3Mt of ore.
Realistically it would be hard to transport more than 50Kt a month of raw ore so that timeframe is 26 months at best.
It also depends on where the ore is treated whether on full toll treating contract or campaign treating. With campaign treating this means the processor would run say 1 week a month on pure Cangai ore. Blending with third party processor doesn't look like an option as Noble have the rights, if they take up the MOU, to sell the Cangai concentrate. If it got blended with the processors ore the processor would have the right of sale.
If they find the third processor all the fine details will be released via a ann of feed grades, run per month and expected recovery rates. I have just given possible scenarios.
