NioCorp Developments Ltd. ("NioCorp" or the "Company") (NASDAQ:NB), announced today that it has finalized the purchase of an additional 325.77 acres of land associated with its Elk Creek Critical Minerals Project (the "Elk Creek Project") in Nebraska. The acquisition provides NioCorp with ownership of all land that hosts the Elk Creek Project's Mineral Resource and Mineral Reserve and all acreage necessary to commence construction once project financing is obtained. This ownership position includes all necessary surface and mineral rights.

Through its land ownership position along with options to purchase additional lands adjacent to that position, the Company has enough land to support planned commercial operations and potentially expand its current Mineral Resource and Reserve beyond the current 38 years of estimated mine life.
