The product now is a high grade concentrate with low levels of deleterious elements with the addition of the fines circuit nothing changes, we will still produce a high grade concentrate with low levels of deleterious elements.
There is no lowering of quality with the addition of the fines circuit.
As for qualified dialogue we are all still waiting to here you explain how drill holes starting from 0-2 m are not from surface? You have so far proven nothing more than yourself to be a fiend for half truths and exaggerator of non existent issues.
As I explained in my last post, those drill holes could not possibly have been from tailings because the tailings dam is very difficult for a drill rig to access and if you were only taking drill samples from a tailings dam (max depth 12m) why would you carry on drilling under it (the tailings dam was built on top of barren ground)
In terms of half truths let us see a daily log sheet or a monthly production spreadsheet, showing basic plant production data. If the DMS was running at 240 tph, as they claim, for 85% of the time, theyd be producing over 20kt of saleable spod per month. We know that they haven;t gotten even half of that yet. 54kt in the 6 months Jul 1-Dec 31, which is too low to be economic. You cannot change those basic, facts. Another thing that Mr Turner might address is the quality of ore reporting to the crushing plant and the quality reporting to waste. The miner knows that he gets paid a higher amount for sending ore to the crushing plant, so will attempt to do so, even with sub-economic grade ore. A tightly run operation will appoint a geologist to go into the pit and closely supervise the excavation of the ore, according to the cut off grade, feed envelope. The samples of selected ore has to be treated immediately, in the on-site lab to corroborate the expected feed grade. Sending low grade ore to the plant deeply affects the economics of a marginal operation, such as this.
Here you go again talking half truths.
1. "running at 240 tph, as they claim, for 85% of the time"
Wrong again for the 100th time your telling lies again and inventing facts to suit your agenda.
They said upto 249tph, the goal is to eventually get to 240tph, no where has it ever been stated that A40 is running "at 240 tph, for 85% of the time".
See the through puts for 2 out of 3 quarters so far are 172 and 202, thats an average overall run rate of 187tph, no where near 240tph.
2.Your whole carry on about "sending low grade ore to the plant deeply affects the economics of a marginal operation"
It's been stated 50 times over they are commissioning on lower grade ore and higher strip, both of which are scheduled to improve from now through to February.
Still you seem to not grasp that we are striping through low grade ore zone to get to the higher grade ore.
Answer me this what makes more sense?
Your thinking
A: Not using the lower grade ore to commission the plant do that with the better grade ore instead, just keep the plant turned off and dump all the lower grade ore.
or
Calderwood thinking
B: Run the lower grade ore through the plant to commission it make alittle money and save the better grade ore for a fully dialed in plant.
I think it's becoming rather obvious to us all why your no longer in the job, you have come on here trying to prove some kind of point, but so far all you are doing is a good job in embarrassing yourself with these ridiculous allegations.
