i, <br /> 11 <br />' 1 slurry deposition method, this is probably going to <br /> 2 work about as projected, but even that is not <br />' 3 accuratel <br />d <br />l <br />d i <br />th <br /> y mo <br />e <br />e <br />n <br />e permit application. But <br /> 4 in winter conditions, in rainfall or low temperature <br /> 5 conditions, which at this elevation of 8600 feet are <br />' 6 going to be quite common, the low temperature <br /> 7 conditions, the tailings as deposited may well <br /> 8 entrain a substantial amount of the HCN which will <br /> 9 not be released, and once it's entrained in that <br /> 10 l <br />it <br />i <br />l <br />i <br /> s <br />urry, <br />w <br />volat <br />l <br />lize extremely slowly. <br />' 11 So I think that we can't assLame that <br /> 12 these tailings, as deposited, are going t:o be <br /> 13 benign. The only lab test that we have i.s a very <br /> 14 limited sample and, frankly, didn't model the <br />' 15 variety of field conditions which will affect the <br /> 16 actual tailings deposits, so I think that we should <br />' <br /> 17 be treating this tailing deposit as a hazardous <br />1 18 waste facility. <br /> 19 The liner that's proposed is actually a <br />' 20 step backwards from the liner that was proposed for <br /> 21 the heap leach facility.
