RE:@jimbowieWisGuy1 wrote: @jimbowie This from today's NR: Both of these findings indicate good potential for enhanced gold recovery utilizing mechanical sorting and ability to treat finer crushed material. 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.
