Though most of our stuff went to Chile. I remember having bloody noses all the time in Chile which I attributed to the heap leech use of sulfuric acid, though in Chile the elevation was pretty high. I think over 14000 ft. The acid spay was a dilute solution but just spread by sprinklers much like lawn sprinklers. I guess it was better than the gold mines which used cyanide.
