What ate the tnittetals and heavy metals that this mine will add to <br />the Noah Clear Creek? <br />Pnxes'sin~~ Plant and Pnduc:t Shx;dvile area: The ephemeral stream coming from the Waste Rtxk <br />pile and snail sediment pond, will pass rhea the Sediment Pond about at T350'. it would flow over the cut <br />cliff at 7300 feet, and flows fader or wee the Pra•essing t'Lan[ fill or tuck floor [n emerge in the <br />l~tmament Sediment Pond below( no depth hem given).
