This implies that mechanical sorting can potentially treat all crushed material generated at Karratha. If you remember, the first sample from Purdy's Reward run through a Steinert sorter, sorted out 82% of the gold into a 2% mass pull. The entire sample then had to be re-crushed to 2mm to be assayed to get the remaining 18% of the gold. What this NR implies that the sorter can now get (I"m guessing) 99% of the gold in a mass pull of 3% on 1 pass through the sorter with no additional work required. Quite the change in the last 3 years. From 82% of the gold in 2% mass pull to 99% of the gold in 3% mass pull. So for every ton of ore you process through the sorter, you get a concentrate weighting 60 lbs. This concentrate would average 67 gpt assuming a head grade of 2 gpt. A truck can haul 22 tons a trip. That equates to 733 tons per day sorted, which one sorter can easily handle. If Novo wants to process 5,000 tons per day at Purdy's then it would need 6 sorters feeding concentrate to 6 trucks per day. 322 ounces of gold per day - 117,000 ounces per year. Looks like they have enough tons to operate Purdy's and Comet Wells for 30 years at 117,000 ounces per year. This is hard to believe but it's coming closer to being proven.
If Novo added 120 tons per day at 67 gpt to run through the mill, it would increase head grade from 2 gpt to 3.5 gpt.
Some people are just no good at numbers WG. The sorter on order is a 400 tph. Lets say it actually runs at 400 tph, which it wont, and that it works 24 hrs a day, which it wont, it would process 9600 tpd, which it wont. At a mass pull of 3% for 99% of the gold (righto), thats 9600 x .03 = 288 tpd of concentrate. How he arrives at 733 tpd that one sorter can "easily" produce I have no clue. Maybe its retard math. As for the 22 tons per truckload, I could tell you different, but whats the use. Fabrix is much closer than Jimbowie on that. In fact hes bang on, at a minimum, without oversized units.
Cal me Jay, or JJ, or J Johnson , or Joseph Jay Johnson, but dont call me Jade.

So 288 tpd with the above assumptions, but they wont do anywhere near 400 tpd on average, thats the maximum capacity depending on the type of material processed, size, etc etc. Lets be very generous and say 300 tph (actual probly closer to 150 is my guess, the slower it goes the more gold you pick out I would assume). And lets say they actually work 2 10 hour shifts a day which I doubt, so thats 20 out of 24 hours a day. So now that 288 tpd machine actually produces:
288 x 20/ 24 x 300/ 400 = 180 tpd. So now that 1 machine to easily produce 733 tpd concentrate is really 733/ 180 = 4.07 machines.
And those machines dont run by themselves, so you need say 2 more men for each additonal machine, more compressed air, generators, fuel for generators, more loaders to feed and clear, more food, beds, johnny on the spots and hookers flown in on weekends, and before you know it it costs more than its worth.
Sorry, my mind wanders when Im sitting on the crapper.
Back to January.
