Chuck; More time to wait. I assume that the results are full CoC with Bateman? In that case it is an exercise in leach optimisation of uncertain duration or outcome. If thet get a leach with good recovery and low cost there seems to be sufficient value for a low cost heap leach process. There does not seem to be enough for an autoclave process BEMA style. There might be some chance for a microwave enhanced situation, where the microwaves are preferentially absorbed by metals and other high conductors and if the intensity is high they explode like popcorn(?), or at least dramatically enhance the surface area, and thus make leaching easier. SInce the inert and non cunducting particles do not dissipate the microwave energy it is not wasted on them. Lots of food for research. Bill

<< I have heard of mines operating in Nevada right now that are turning a profit on their ore bodies and they are doing it at a higher recovery rate than fire assays are showing. >> That is a rumor. The fact is that mines always recover less than what the average grade of the deposit (provided by assays) is. In heap leaching operations the recovery rates are between 70% and 90% with an average of probably 78%. In hard rock mining, recovery rates are above 90%. In all cases, they are never above 100%. If there is one outfit that recovers more than what was assayed, I would like to know it.
