Eyasi & Balangida
The Company’s additional two projects, Eyasi and Balangida, are located in north central Tanzania. Both have exceptional helium gas concentration at surface, and ideal geology for source, reservoir, trap and seal.
These projects are not as advanced in their exploration as the Rukwa project, however Helium One has commenced work programmes, including an airborne gravity survey, to define the prospective sub-surface structures.
The Eyasi project area is located in north central Tanzania. The Company holds four Prospecting Licences covering an area of approximately 910 km2. Twelve leads have been mapped by utilising and interpreting the CGG Multiphysics, with surface helium seepages occurring in proximity to the mapped leads.
Gas analysis conducted during 2015 found helium concentrations of 4.3% from thermal springs. Lake Eyasi is a shallow, seasonal salt lake, with source rock, trap and a high likelihood of salt seal potential. With lake depths typically of less than one metre, typically sections of the lake periodically dry out.
The project is supported by established infrastructure and is 800 km from the port of Dar es Salaam via a sealed arterial road. Arusha, Tanzania’s fourth largest city is 150 km from the project.
The Balangida project area is located in north central Tanzania. The Company hold one Prospecting Licence covering an area of approximately 260 km2.
No historic work has been undertaken within the Balangida project area, but Helium One has commenced limited exploration across the project. Surface helium seeps occur in the project area, with concentrations of up to 10.6%.
Gas analysis conducted during 2015 returned helium concentrations up to 10.6% from thermal springs. Like Eyasi, Lake Balangida is a shallow seasonal salt lake, hosted within a sedimentary basin with potential for source rock, trap and seal, and a high likelihood of salt seal occurrence.
The project benefits from established infrastructure and is 690 km from the port of Dar es Salaam via a sealed arterial road. The project is 100 km from the regional capital, Singida.
