Tim, I'm lost. GPGI's ore appears to be low grade on the evidence discussed. Assuming 15 tons per day for seven days comprises one shipment of concentrate (from 105 tons ore), and that the first two shipments combined yielded approximately 7 oz Au and pgm, this results in 0.03 ounces per ton of precious metals from the ore pile. Aside from any pre-processing treatment of dirt pile ore at the plant, the dirt pile ore was comprised of mine tailings before being sifted for gravel for road work? The grade might then be much lower than .03 opt pm? If the absence or heterogeneous distribution of pms in dirt pile ore, rather than chemistry, were the cause of negligible results from shipments 3-6, then 7 oz pm from a total of 6 shipments represents approximately .01 opt Au + pgm? If all of the above were true, the grade could be an order of magnitude less than .03 opt of precious metals? The above is very simple minded, but is based on the recently announced information. Apparently GPGI management has been carrying out this R&D for 18 years. It seems remarkable that we are still guessing about opt grades for Au, Pt, Pd and Rh from dirt pile ore. Your and others' comments would be welcome. Ptask
