Geoff, you do not want to see my "full" list of questions, I assure you. It will be nice if you get answer to just these to start with. As for personnel, you cannot put some stiffs out there to carry out smelting, the guys have to know and understand what they are doing, they have to be experienced enough to judge the temperature of the melt from its glow and color, charge the copper the right way and then pour the stuff out after the appropriate collection and fining process. There might even be a need to control the atmosphere above the melt to preserve some reducing conditions. None very standard procedures, all require a good deal of well developed "gut feel" for the process, or alternatively extremely well instrumented and controlled firing process. The same goes with electrowinning. You spit into the electrolyte and you change the process' (typically in favor (VBG)) parameters, you spit too much and dendrites grow all over the place and short the electrodes. Zeev
