The Leadville Mill M 1990-057 <br /> EXHIBIT C—MILL PLAN <br /> Page 4-2 <br /> FigblFe ^ ' thFOUgh Figu The current facility includes 2 separate metal buildings: <br /> • Mill Building. The mill building contains the fine ore bin, reagent storage area, <br /> ball mill circuit, flotation circuit, concentrate thickener, laboratory, mill office, <br /> safety/training/change room, concentrate storage room, and restroom; and <br /> • Crushing Building. The crushing building contains the RoM grizzly, primary, and <br /> secondary crushers. It is connected to the mill building via an enclosed <br /> conveyor crossover bridge. <br /> Upgrades proposed include: <br /> • Truck scale. <br /> • RoM storage pad. <br /> • New crusher building. <br /> • Conveyor connecting new crusher to main building <br /> • Leach tank and detox tank pad <br /> Other facilities include: <br /> • 2 primary water monitoring wells. <br /> • 1 shallow monitoring well in mostly dry perched aquifer. <br /> • Electric utility line. <br /> • Trailer foundation. <br /> • Sewage lift station. <br /> • Upper and lower gravel mill access roads. <br /> • 3 ore stockpiles, 1 topsoil stockpile, 1 TSF overburden stockpile, a TSF <br /> redesigned to meet CDRMS performance standards, as summarized in (See <br /> Section 4.3, Tailings Storage Facility and geotechnical analysis (Sec. 15.0, <br /> Geotechnical Stability 6.5). <br /> The property boundary is surrounded by a 4-strand animal-friendly fence, as <br /> prescribed by CDOW (Appendix 7-9). <br /> The facility can be accessed by either an upper (north) or lower (south) road. Within <br /> the permit area, these roads connect to a 24ft-wide gravel access road connecting to <br /> US Highway 24. RoM ore haulage will access the grizzly on the upper mill road. <br /> Concentrate shipments, will use the lower mill road. <br /> The fine ore feed bin, chemicals and reagents are contained in the Mill Building <br /> (Figure). Reagents and chemicals used in ore processing will be stored in over-pack <br /> drums or within secondary containment structures. Any leakage, or containment <br /> issues with the stored chemicals or reagents will be directed to the mill sump and then <br /> to the TSF (Figure 4-3)or collected and disposed in an approved disposal facility.
