mine portal technical

"update following the launch of construction on the mine portal at the Company's Elk Creek"

A mine portal is the main entrance or opening that provides access from the surface into an underground mine, similar to the doorway of a building leading into interior rooms. For investors, the presence, quality and timing of a portal matter because it affects how quickly and safely a mine can be developed and operated, influences construction costs and schedules, and can signal progress toward production and revenue generation.

underground mine operations technical

"role of the mine portal in the planned underground mine operations. Management will also"

Underground mine operations are the work of extracting minerals or metals from beneath the earth’s surface through tunnels, shafts and chambers rather than open pits. Like running a complex workshop in a basement instead of a backyard, they tend to be more expensive, technically demanding and safety- and regulation-sensitive, so investors watch them closely for higher costs, production risk, permit and liability exposure, and the potential for long-term, steady resource access.

ABOUT NIOCORP

NioCorp is developing the Elk Creek Project that is expected to produce niobium, scandium, and titanium. The Company also is evaluating the potential to produce several rare earths from the Elk Creek Project. Niobium is used to produce specialty alloys as well as High Strength, Low Alloy steel, which is a lighter, stronger steel used in automotive, structural, and pipeline applications. Scandium is a specialty metal that can be combined with Aluminum to make alloys with increased strength and improved corrosion resistance. Scandium is also a critical component of advanced solid oxide fuel cells. Titanium is used in various lightweight 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 making of neodymium-iron-boron magnets, which are used across a wide variety of defense and civilian applications.
