Richard, If they are pumping water out of an old mine and discharging it after the resin columns, without a permit or permission, they are in big trouble. I suspect they are placing it back in the mine so it can dissolve more gold and platinum. I also hope they are using a pump powered by a surplus photo-voltaic cell or their pumping costs will probably exceed their income. VBG

Richard, when I was a kid growing up in the tropics, we used to play around the salt flats. They let in seawater and then allowed the ponds to evaporate until salt crystals formed, and raked up the crystals in piles to dry. While raking won't work for metals extraction at OG, perhaps concentration by pond evaporation can. The energy use for concentrating the leachate is free, and the pond can simply be replenished by pump as needed. While evaporation will occur anytime during the year in AZ, it would be especially productive in the warmer months. I am only thinking aloud here, and have no idea how concentrated it ought to get before passing thru the columns, but costs should be much less than the ore-leaching methods. So even if the yields are small, it still could contribute to the bottom line. Any hydrologists out there know how much can evaporate from a pond X by Y for Z days?
