About NioCorp

NioCorp is developing a critical minerals project in Southeast Nebraska which will produce niobium, scandium and titanium. The Company is also evaluating the potential for production of several rare earth by-products from the Project. Among other things, niobium is used to produce high-strength low-alloy (“HSLA”) steel, a lighter, stronger steel used in automotive, structural, and pipeline applications. Scandium is often combined with aluminum to make alloys with increased strength and better corrosion resistance. Scandium is also an essential component of advanced solid oxide fuel cells. Titanium is used in various alloys and is a key component of pigments used in paper, paint and plastics and is also used for aerospace applications, armor and medical implants. Magnetic rare earths, such as neodymium, praseodymium, terbium, and dysprosium, are critical to the manufacture of neodymium-iron-boron (“NdFeB”) magnets, which are used in a wide variety of military and civil.
