Just wondering how you got on with the fine chrome figures?
I'm struggling to make sense of the numbers and where the chrome is coming from to be honest. From what we know (or think we know from the info we've been given), is that fine chrome is being recovered from tailings we've already recovered course chrome from, and being tailings they would have already had a first pass at chrome recovery.
The quantity of tailings varies in the news releases, but say we've got approx 1m tonnes, which roughly fits with the processing capacity and length of time to process for course chrome.
From those tailings we've already produced 156K tonnes of chrome concentrate. The remaining quantity would then take roughly 3 years to process at 25k tonnes a month, and at 5k tonnes of chrome concentrate a month would mean we will have recovered over 300k tonnes overall from 1m tonnes of tailings. And also means the tailings started off containing at least 30% chrome.
Now we're talking about chrome concentrate, not pure chrome, but that seems a remarkably high % for material that had already had chrome extracted.
There was talk of bringing in 3rd party material to DCM, but its never really been that clear what actually happened with that or how much was bought in, and there's been no mention of continuing course chrome recovery alongside fine chrome at DCM.
