(COM, Inc.) u located 10 mile west <br />of F3ailder Colorado in the SE 1/4 of the NW 1/4 of Seaian l2, T1N, R72W, in the 6tlt <br />Principal Meridian The mill artd associated tailings pond u et an elevation between 8525 <br />end 8600 feet There are currently 6.20 age permitted and 3.46 aan disttrrbcd <br />The mill proaases ore by Qushing, end grinding The ore u separated from waste rock <br />(tatlirtgs) by gravity seperatian on table end gravity cartes, end by flotation using soda ash, <br />pure oiI arad xanthete to cadition the ore and promote flotaion The teilirtgs are thiekated <br />in a thickener tank and pumped outside to s linod tailings pad adjacent to the.mill building <br />through a PVC pipe that is buried most of the way to the tailatgs patd Ore u truclted to the <br />mill end dumped in a two oompamterrt ore bin adjaaru to the mill. The ore u withdrawn <br />fttan the bim by ce~nveyon at the bottom of the bins. Ore is conveyed into the mill building <br />when the processing is completed The mill building is a 70-foot by 120-foot maml building <br />that house all of the gushing, grinding, catcertttating, and thicitming cutwU. <br />Tailings ere spigoted into the tailings pond, gearing a heath arts and a pond area seated by <br />decant water. The decent watt i, pumped back to the mill to be reused in the processing <br />circuit During arty storm events, storm water u drawn off the tailings thrnuglt a docent line <br />above the railings sends and thtutglt a PVC disclta:ge li:te tra the Hazel A edit located below <br />the tailittp pad. The storm water u stored behind a bu[khead in the edit and pumped back <br />to the mill to be used es proxss water a diverted to the tailings pond fa evaporation Any <br />leakage from the bulldteed v contained by a cofferdam.
