About Rift Helium:

Rift Helium is building the primary helium supply the future demands. We hold 283 km² of strategically positioned licences in Tanzania's Rukwa Basin, next to confirmed helium discoveries. The system is proven and we are targeting where helium accumulates.

Following a successful IPO, Rift plans to acquire 3D seismic data and utilise cost-efficient drilling techniques to test these structures and target economically recoverable helium reservoirs, with a clear pathway toward commercial production.
