Rift Helium is a helium exploration and development company. The Company is currently focused on the exploration of a discovery-ready, non-hydrocarbon associated helium bearing acreage at its early-stage Upepo Project, located in southwestern Tanzania, within the Rukwa Rift - forming part of the East Africa Rift System (the "Upepo Project").

The Upepo Project comprises three prospecting licences over 283 km² in the Rukwa Basin, near to existing helium projects operated by Helium One Global Ltd (AIM: HE1) ("Helium One") and Noble Helium Limited (ASX: NHE) ("Noble Helium"). The Company has identified five discrete exploration leads, primarily on its eastern licence, PL 12093/2022. The Company aims to leverage its third-mover advantage in the Rukwa helium province and intends to benefit from the reduced geological risk in light of recent helium discoveries by Helium One and Noble Helium.
