It’s poised to mine one of the largest, if not the largest, rare earths deposits in America, but the site doesn’t just have light rare earths like neodymium or praseodymium, used in industrial magnets for wind turbines and electric vehicle motors. It also has heavy rare earths like terbium, dysprosium and samarium, which are rarer metallic elements used in high-tech applications. Those heavy rare earths are harder to come by but critical for everything from fighter jets to smartphones. Their presence in significant amounts means the opportunity at Halleck Creek could be bigger than just mining a natural resource and shipping it out.
