Nebraska Governor Pete Ricketts Nominates the Elk Creek Project to the White House as a “High Priority National Infrastructure Project”

CENTENNIAL, Colo., July 31, 2017 -- Governor Pete Ricketts (R-NE) has nominated the Elk Creek Superalloy Project as a “High Priority Infrastructure Project” in response to the White House’s January 24, 2017 Executive Order entitled “Expediting Environmental Reviews and Approvals For High Priority Infrastructure Projects.”  In this letter to the Administration, Governor Ricketts made these points:

“Key to the success of a national infrastructure re-building is utilizing as many American-made materials as possible - particularly the high strength steels that form the backbone of America's transportation, manufacturing, and defense infrastructures.  The Elk Creek Superalloy Project can help the U.S. produce American-made "super steels" for infrastructure projects across all 50 states.  The Project will establish the first-ever production in America of niobium, a metal that helps to make High Performance Steel (HPS).  These super steels are increasingly used in highway bridges and in virtually all mega-steel infrastructure projects in order to reduce corrosion, lengthen lifespans, cut costs, and reduce environmental impacts. American-made HPS steel can help highway bridges last in excess of a century.  That will reduce taxpayer costs and strengthen safety... We need niobium, Mr. President, yet we don't mine a single pound of it in the U.S. today.  Nebraska wants to change that, and as rapidly as possible.”

On Behalf of the Board of Directors,

"Mark Smith”

About NioCorp
NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce Niobium, Scandium, and Titanium. Niobium is used to produce superalloys as well as High Strength, Low Alloy ("HSLA") steel, which is a lighter, stronger steel used in automotive, structural, and pipeline applications.  Scandium is a superalloy material that can be combined with Aluminum to make alloys with increased strength and improved corrosion resistance.  Scandium also is a critical component of advanced solid oxide fuel cells.  Titanium is used in various superalloys and is a key component of pigments used in paper, paint and plastics and is also used for aerospace applications, armor and medical implants.
