EXHIBIT D
<br /> (H) Expected Incidental Products
<br /> The secondary commodities mined at the West Side Placer project encompass a range of valuable materials. Titanium
<br /> minerals,including ilmenite,euxenite,columbite,and rutile,are essential for producing titanium metal,widely used in
<br /> aerospace,pigments,and medical devices. Garnet is primarily used as an abrasive in industrial blasting,water-jet cutting,
<br /> and surface preparation.Magnetite serves as a crucial iron source for steel production and is used in coal washing,MRI
<br /> contrast agents,and catalysis. Zircon plays a vital role in ceramics,refractory materials,and as a source of zirconium
<br /> for nuclear reactors. Specialty sand finds application in glass-making,construction,filtration,and fracking,while gravel
<br /> supports erosion control,landscaping,and foundational stability in construction. Road base,composed of gravel and
<br /> sand,provides essential support in road construction,and clay is integral to ceramics,soil management,and numerous
<br /> industrial applications. Table D.(H).1 Expected Incidental Products shows the list of incidental/secondary commodities to
<br /> be mined and extracted.

<br /> Secondary Titanium (Fe,Ti)203 a Titanium Metal Production:The primary use of titanium minerals is in the production of titanium Yes
<br /> Minerals (Y,Ca,Ce,U,Th)(Nb,Ta,Ti 2)0 6 metal,which is known for its high strength,light weight,and corrosion resistance.Titanium
<br /> (ilmenite, Ti02 metal is used in aerospace applications for aircraft components and space vehicles,as well as
<br /> euxenite, in military equipment.
<br /> columbite a Pigments:Titanium dioxide(Ti02)is widely used as a white pigment in paints,coatings,plastics,
<br /> and rutile) and paper due to its high refractive index,which gives it excellent light-scattering properties.It
<br /> provides whiteness and opacity to these products.
<br /> • Welding Rod Coatings:Titanium minerals are used in welding rod coatings,where they help
<br /> stabilize the arc during welding and improve the properties of the weld.
<br /> • Cosmetics and Sunscreens:Titanium dioxide is used in cosmetics and sunscreens due to its
<br /> ability to scatter ultraviolet(UV)light,providing protection from the sun's harmful rays.
<br /> • Aerospace and Defense:Due to its high strength-to-weight ratio and resistance to extreme
<br /> temperatures,titanium is used in various aerospace and defense applications,including aircraft
<br /> frames,engines,and armor plating.
<br /> • Medical Devices:Titanium's bio-compatibility makes it suitable for medical implants,such as hip
<br /> and knee replacements,dental implants,and surgical instruments.
<br /> • Desalination Plants:Titanium is used in desalination plants for its corrosion resistance,
<br /> particularly in parts exposed to seawater.
<br /> • Chemical Processing:In chemical processing industries,titanium is used for equipment such as
<br /> heat exchangers,reactors,and piping systems,especially in environments that are corrosive or
<br /> involve high temperatures.
<br /> • Automotive Applications:In high-end and performance vehicles,titanium is used for components
<br /> like exhaust systems and engine parts,leveraging its strength and light weight.
<br /> Incidental/ Garnet jMg,Fe,Mnl3Al2(SiO4)3 Abrasive Blasting Media:Garnet is widely used as an abrasive blasting material for surface preparation in No
<br /> Secondary industrial painting and coating applications.Its hardness and angular shape make it effective for removing
<br /> rust,paint,and other coatings from metal,wood,and other surfaces.
<br /> Water-jet Cutting:Garnet is a preferred abrasive for water-jet cutting machines,which use high-pressure
<br /> water and garnet abrasives to cut a wide variety of materials including metal,stone,glass,and composites.Its
<br /> sharp edges and hardness allow for precise and efficient cutting.
<br /> Abrasive Powders:Garnet is ground into powders that are used as abrasives in sandpaper for woodworking
<br /> and automotive industries.It's used for finishing and polishing purposes due to its effectiveness in smoothing
<br /> surfaces.
<br /> Filter Media:Garnet is used as a filtration media for both water and air filtration.Its chemical stability and high
<br /> specific gravity make it effective in filtering out contaminants.
<br /> Water-jet Looms:In textile industries,garnet is used in water-jet looms for the efficient and precise cutting of
<br /> fabrics.
<br /> Surface Preparation in Petrochemical Industries:Garnet is used for blast cleaning surfaces in the
<br /> petrochemical industry,preparing them for painting or coating.
