Zeev,

A couple of points

1. It takes only a fraction of 1 ton of copper to process 1 ton of ore. The exact quantity I do not have at hand. Also, the copper used in the electroplating process is recycled. Hence costs for copper are basically not a significant factor in overall costs.

2. It is true that there is a disconnect between the Brian Russell COC and 110 ppm you found. This remains to be resolved. I believe, but cannot prove, that it has to do with the method Iseman used in processing the material Brian Russell sent him. Russell Twiford has always claimed that standard methods do not adequately demonstrate the quantity of goodies in the ore. It remains for him to prove this. We will know before much longer.

However, even with 13 grams per ton (and I really believe this is a low ball figure and that the more typical figure for this method of testing will be in the 18-20 gram per ton range) the deposits are economic by a considerable margin. Remember that Brian Russell stated that in South Africa, with deep deposits 6 grams per ton is profitable.
