Zeev thank you for clarifying a problem which has been lurking in the back and even the forefront of my mind for quite a while. As you indicate the permutations of possible outcomes is a number of variables multiplied by the potential range of each variable, admittedly a moderately large number. Although my suspicion is that the variables or their modifications are probably not discreet but operate on a continuum therefore approximations rather than plus minus results are what we might expect. If so, this makes the difficult problem of multiple permutations a bit more manageable. But getting to my problem, I have long wondered why Twiford has found results in the multiple thousands of dollars per ton of metals in his evaluations, The numbers he has given me I will not repeat because they are hardly believable. But Twiford is not a liar or a fool. How come the results, so far have come no where Twiford's findings. Your observation throws light on this. However, it is of considerable interest that some level of results have been consistently produced. And this suggests not only the presence of the pgms and gold but the hopeful and likely inevitability of scaling up as the variables are nailed down. Admittedly this may take some onion peeling but in the meantime I tend to believe that before we get to an approach to Twiford's numbers, or even a modest percentage of them, we will be producing on a viable and economic basis. I believe that McKay will follow a statistical approach to the evolution of the optimum process rather than Jack's description of Edison's buck shot method. When a youngster, regarding Edison's failure to produce a working light bulb, stated" You failed again" Edison responded with: "No, I learned another way you cant make a light bulb". So be it.
