@Names little for future reference for both of us.
This is my understanding and I’m not an expert.
FS states mass yield below 13%.
Metallurgy testwork states above 17%.
CG and company recently stated yields above expectations with low grade feed.
I will take that as meaning exceeding FS.
I’m going with the half way mark now of 15%.
It may be ambitious it may not time will tell and it will vary on head grade and other factors.
The company stated 240 tph averages in the future (if they say this you can expect they have a high conviction for at least 240tph to Be achieved imo);
240tph x 20.4hrs x 365 days = 1.787mtpa / 100 X by 15% = 270ktpa.
That coincides with my best guess from the other post.
Possibilities for that to increase with higher tph, less downtime, higher grade ore and other optimisations (they have also already seen areas for further optimisation for DMS 2 that they can’t change in DMS 1), of course it could also decrease with the opposite happening such as increased downtime due to unforeseen events etc.
Fines I haven’t done any proper cals, seems to Be a moving target that they are figuring out.
Based on 161 tph throughput we were expecting 25% uplift with a fines circuit.
Again we could expect that be conservative. They have hit the ball out of the park on everything to date from an operational perspective. With much higher throughputs It stands to reason we might be expecting a lot higher fines output than 50ktpa.
I think this is what they are optimising though, to reduce fines and increase DMS output through different crush sizes/screen sizes/other variables. With reduced fines as far as I’m aware This will reduce processing costs so it’s advantageous.
So best guess for me for now;
270ktpa DMS
320ktpa DMS + fines
Very surprised to see anything less than 300ktpa combined whichever way the ratios work out.
