Zeev,

Based upon the fact that local SFA of a sample produces results that cannot be reproduced by COC SFA of similar ores for at least several different companies (NAXOS, IPM, MAXAM and others), I was attempting to explore alternative explanations for why this might be happening.

The easiest explanation for why this is happening, we've all heard from various "expert" sources already. Their explanations all involve some aspect of "scam". If we eliminate this explanation (I believe we can for GPGI - they are producing metal) from our list of possible explanations, then we can concentrate on discovering exactly what it is about these ores that contributes to their irreproducible SFA result behavior pattern.

Now, a COC sample is most likely not to be handled in the exact same manner as a local sample before the SFA occurs. About the only thing we are guaranteed of with COC is that the sample wont be salted. If the sample contains monotomic elements, and they are driven off by forces or fields that caused them to tunnel, then they wont exist in the sample when it comes time to perform the SFA. The only way that I can think of to insure that the monatoms don't tunnel, is to contain the sample in a magnetic bottle. The monatoms should try to move away from the field, but since the field completely surrounds the sample, they will be driven toward the center of the "bottle".

One other point, if control of magnetic fields (or other forces) acting on a sample is not maintained during the heating or other process, the possibility of driving off the monatoms also exists. If you drive off some percentage of the monatoms while processing the ore, and the ratio of monatoms to metallic clusters is large in your sample, the results of your yield will have a large variance from batch to batch and produce the irreproducible result behavior pattern we've come to know for all DD's.

I am all for "letting them extract the goodies", but I also feel that until this problem of irreproducible results is addressed and resolved at some level, all DD's will continue to languish in the BB stock arena with a stigma of scam hanging over their heads. I also believe that this problem is one of the key contributors to the never ending production delays we've experienced with several of the DD's.
