RE: Sable key to understanding 2025 copper28 Feb 2024 13:56

i sympathise with you concerning sable. there are unknowns currently - hopefully they will be clarified by multiple rnss shortly.
i think additional refining capacity will be needed by jubilee in the next 12 months because:
the roan 6 year deal to be delivered via the 50000t/month upgrade is scheduled to be refined by sable. as you say, it is about 13000t / year when running at full tilt. i hadn't picked up an 8000/5000 sulphide/oxide split but i'm happy to go with your numbers;
the monkoyo project is due to get a 25000t/month module. i thought this was graded at 1.5 - 3% and on-surface discarded material. the rns (8/2/24) mentions the deeper pit providing 25000t/m ore. is this additional to the waste rock at monkoyo? (that was one of my questions at the cancelled investor presentation.) taking only 25000t/m @ 1.5% copper, i make that 375 tonnes per month or 4200t /year. i haven't seen a sulhide/oxide split yet,but i assume this is why sable is getting the 2000t / year sulphide circuit upgrade;
so far, so good.
but, the waste rock project also mentioned refining its'output a sable - up to 12000 tonnes, i think (in a full year of operation, not all attributable to jubilee). this may not be until 2026 but a some will be available in 2025. the wh ireland not gave a 60/40 oxide/sulphide split.
mufulira **** will be processed at mopani copper mines kitwe facility we assume as part of the jv with them. where will the other tailings be refined? are they all sulphides (with or without cobalt)?
there are small scale miners that currently feed sable. the 2023 annual report states this feed is 1.87% copper and we were given the figure of 130t / month in an rns about this time last year. is this to be redirected to mcm kitwe?
as i say, hopefully we'll get specifics soon.
