The Rift REE Project is a globally significant rare earth and niobium project located in southeastern Nebraska, USA, at the highly prospective Elk Creek Carbonatite Complex near the village of Elk Creek. With a diameter of 6–8 km, it ranks among the largest carbonatite bodies in the world. The project is positioned within a Tier-1 jurisdiction, offering excellent infrastructure and geopolitical stability.
Two target areas (East Zone and West Zone) include multiple historical drill holes that are well-mineralized in REE’s.

Geology of the Rift REE Carbonatite as Expressed in Drill Holes at an Elevation of 120 m ASL (Roughly 230 m Below Ground Surface) (Drenth, 2014). Age relations among the carbonatite units are poorly known, and ordering of units within the figure is not meant to imply cross-cutting relations.

With large portions of the carbonatite untested using modern methods, the Rift RE Carbonatite offers a unique opportunity to advance critical minerals exploration in the United States. The combination of strong historic results, underexplored REE targets, and favorable jurisdiction makes it a compelling addition to any exploration portfolio.
