I remembered the elevation as considerably less than your figure of 4000+ metres. In any case, heating the leach solution doesn't seem to me to be an insolvable problem, nor all that expensive. Yes, the deposit is deep, but it's big and getting bigger and Barrick likes it. Feline, clearly it is the second "F" in your bio quote that you are looking for. ..........well, "F" you, try somebody else, I don't have the time..... .....nor the interest ......... vaya con D¡os ........... marcos

Feline; There are a few problems with a heap leach in cold weather. Pipe freezing and surface freezing on the leach heap. Genarally these can be solved by heated lines, or the new compressible balls in the lines that cut the peak pressure if a freeze occurs. The lines are under less than 25 PSI, unless there is a long gradient in which case the usual 15 PSI surpressure per 10 meters applies. There is very little snow, and so a bridged tarp strong enough for the wind will suffice to keep the surface from freezin. With the deeps of the pile warming the leach liquid and the exposed pipe minimized and heated there will be little need for any extra make up heat. There must be staff to deal with starange things, but I expect enough staff to be there year round for this situation. The friable material is being tested now, apparently it can be ripped and crumbled readily. There is little hard rock present from reports I have seen. The entire deposit above bed rock drills rapidly with an R/C drill, which tells you it is easy to mine. A certain portion of the overburden will be needed for contouring, but there will be a need for quite a bit of removal. The relocated material can be used for windbreaks, and grading. I am encouraged by this news, as it shows value is there and more continues to be found. Possibly the deeper feeder area sought might have more of the less mobile gold. Bear in mind that the mobile silver may have been carried away from the gold in the deeper feeder area and this could be very significant, especially as the gold is usually higher than the silver in absolute amount, yet here the silver is 400:1 versus gold. When the gold left behind is found it might just knock our socks off. Bill
