EXHIBIT D TABLE D.(H).1 TABLE D.(H).1 EXPECTED INCIDENTAL PRODUCTS- 2 OF 3 Category Product Formula Applications Critical MineraF Incidental/ Magnetite (Fe,MmNb206 Steel Production:Magnetite is a major source of iron,making it a crucial raw material in the production of Secondary steel.Its high iron content makes it a valuable ore for iron and steel industries.Water treatment Coal Washing:Magnetite is used in the coal washing process.Its magnetic properties enable the separation of coal from impurities.Coal particles are mixed with magnetite and water;the mixture is then subjected to a magnetic field which separates the coal from heavier impurities. Dense Media Separation:In dense media separation processes,magnetite is used as a dense medium.This is particularly common in mineral processing to separate minerals with different densities,a method often used for separating diamonds from other material. Magnetic Resonance Imaging(MRI):Due to its magnetic properties,magnetite nanoparticles are used as contrast agents in MRI scanning. Catalysis:Magnetite is used as a catalyst in certain chemical reactions,including the production of ammonia in the Haber process. Electronics and Magnetic Storage:Due to its ferromagnetic nature,magnetite is used in magnetic tapes and hard drives for data storage. Energy Storage:Research is being conducted on the use of magnetite in energy storage systems and as a material for building lithium-ion batteries. Soundproofing and Insulation:Magnetite's density makes it useful for soundproofing and as an insulating material in construction. Incidental/ Zircon ZrSiO4 Ceramics Industry:Zircon is extensively used in the production of ceramics,particularly in the manufacture Yes Secondary of tiles,sanitary ware,and tableware.It acts as an opacifier,imparting a white,opaque appearance and improved strength and toughness to ceramic products. Refractory Materials:Due to its high heat resistance,zircon is used in the production of refractory materials, like furnace linings and foundry molds.It is especially valuable in high-temperature applications where robust and heat resistant materials are needed. Foundry Sands:Zircon's high thermal stability makes it an excellent material for use in foundry sands for casting metals.It can withstand the high temperatures of molten metal without breaking down,ensuring the precision and quality of cast metal products. Zirconium Production:Zircon is the primary source of zirconium metal,which has applications in nuclear reactors due to its low neutron absorption characteristics.Zirconium is also used in the production of super alloys and in various chemical applications due to its corrosion resistance. Incidental/ Specialty Si02 Glass-making:One of the primary uses of high-purity silica sand is in the production of glass.It provides the No On-demand Sand(Spec essential Si02(silicon dioxide)component of glass formula,which gives glass its transparency,strength,and Sand) thermal resistance. Foundry Sand:In metal casting,specialty sand is used as a molding material,known as foundry sand.Its high melting point and resistance to heat make it ideal for forming molds into which molten metal is poured. Oil and Gas Recovery(Frac Sand):In the hydraulic fracturing process used to extract oil and natural gas, specialty sand known as Frac sand is used.It is pumped into wells to prop open fractures in rock layers, allowing oil or gas to flow out. Construction:Specialty sand is used in the construction industry for its strength and durability,particularly in the creation of concrete and asphalt. Water Filtration:Because of its uniform size and shape,specialty sand is used in water filtration systems.It helps to trap and filter out impurities from water,making it cleaner for consumption or use. Sports and Leisure:Specialty sands are used in sports fields,including golf courses(in bunkers)and in volleyball courts,for their consistent grain size and drainage properties. Landscaping:In landscaping,specialty sand is used for its aesthetic appeal and for soil aeration and drainage. Abrasives:High-grade silica sand is used as an abrasive in sandblasting and other abrasive tools,for cleaning and shaping surfaces. Glass Beads and Other Decoratives:Specialty sand can be processed into glass beads used for decorative and reflective purposes in road marking and other applications. Chemical Production:Specialty sand is used in the production of certain chemicals,where silica is a required component. Ceramics and Refractories:In the manufacturing of ceramics and refractory materials,specialty sands are used because of their high silica content and thermal properties.Civil engineering applications Incidental/ Gravel Typically,gravel includes a mix of rock Erosion and Drainage Control:Gravel is effective for controlling erosion and managing drainage.It's used in No On-demand types and sizes,from small pebbles areas that require stabilization against water movement,and in settings where drainage is a concern,such as to larger stones.Common rock types around structures without gutters. found in gravel are: Landscaping and Decorative Purposes:In landscaping,gravel serves both functional and aesthetic purposes. It's used for creating walkways,as a mulch replacement in gardens,and for decorative effects in landscape Quartz design. Granite Construction and Infrastructure:Gravel is a key component in the construction industry.It's used in making Basalt concrete,creating foundations for roads,mixing with asphalt,and filling construction sites.Gravel is also Limestone utilized in producing other construction materials like blocks,pipes,and bricks.In some instances,it's even Sandstone used in blast furnaces as a flux material. 24 HARDROCK/METAL MINING REGULAR 012)APPLICATION Au Pt Industries LLC I PO Box 1424-Edwards,Colorado 81632 1970 306 1 784
