EXHIBIT D <br /> (C) All Water Diversions And Impoundments <br /> The West Side Placer is committed to efficient water management, employing advanced technologies and <br /> methods to reuse water and minimize environmental impact.A key feature of this water management system is <br /> the absence of ponds, for both storage and settling. This deliberate decision to reduce environmental impact and <br /> potential hazards associated with pond storage. <br /> These principles include: <br /> • Contained Water Storage: Utilization of frac tanks for contained water storage.This will avoid the need for <br /> water storage ponds. <br /> • Water Processing/Reuse Technologies: Dewatering cyclones, rapid thickeners, and press filters will be <br /> used for separating solids from liquids efficiently. Dewatering screens will further remove moisture <br /> from processed materials. These processes combined will avoid settling and storage ponds, reducing <br /> environmental impact. <br /> TABLE D.(C).1 <br /> Equipment Primary Function Additional Functions <br /> Dewatering Cyclone Solid-liquid separation,stacking of a Classifies particles based on size and density <br /> sands,clays,and product a Concentrates slurry before further processing <br /> Dewatering Screen Removal of liquids before stacking a Separates solids from liquids in slurry <br /> of final product and tailings a Improves the quality of the final product by reducing moisture content <br /> • Recirculation and economic use of water <br /> Flocculant Injector Injection of non-toxic polymer for a Enhances the efficiency of sedimentation and filtration processes <br /> solid-liquid separation a Reduces turbidity in water <br /> Frac Tank �I Water Storage a Temporary containment of processed or <br /> unprocessed fluids <br /> • Facilitates on-site water recycling and management <br /> Thickener Liquid-solids separation,water a Concentrates slurry by removing excess water <br /> storage a Recovers valuable minerals from the slurry <br /> 17 <br /> HARDROCK/METAL MINING REGULAR(112)APPLICATION Au Pt Industries LLC I PO Box 1424-Edwards,Colorado 81632 1970 306 1 784 <br />
