Hi RA
I’m still mulling over your post where you are suggesting not mining lower grade assets as RR suggested. I don’t really understand how that will fit in with keeping Telfer going. You suggest slowing the rate of processing to prolong life of the plant.
What we know:-
There was 21.6mt in the Dec MRE which is the new mining plan. At least 2mt will have been processed before Ggp get the keys, this will leave around 19mt to be processed in the 15 month plan.
9.6mt will be left in the stockpile this is mostly being mined from the low grade pit in the West Dome.
This leaves around 9mt left to be mined from the plan, around 1mt from underground will be high grade the rest low grade from the open pit.
19mt will be processed in the 15 months, so that is 2 trains working.
If as you are proposing to only use one train the FCF will be diminished by half for Havieron and more cash from the banks will be required to fund this gap.
I don’t really understand your logic on that.
After the 15 months there will be a gap of at least 9 months to fill the mill. As far as I understand there is 8.4mt according to Shaun of weak grade ore this could utilise one of the trains for 12 months (recovery factors are not great for this ore).
The new mining plan due next June will highlight how they intend to fill the mill prior to Havieron ore becoming available and afterwards.
One train will be used for Havieron ore , initially not enough to keep that train going. There will be one months processing for first year, 3-4 months second year and 4 months subsequent years. There will be large gaps in processing.
The other train will be processing any ore from Telfer available in the New plan which is going to be mainly weak open pit ore with possible higher grade from underground .
Until the West Dome deeps come online mining any weaker ores will be a necessity.
