A Zambian geothermal exploration company, Kalahari GeoEnergy, announced the completion of the drilling of eight temperature gradient holes and the commencement of drilling slim wells at the Bweengwa River Geothermal Resource Area.

The project forms part of the company’s resource delineation drill and well testing programme, which if successful will lead to a full technical and commercial feasibility study commencing late 2019.

Bweengwa River is situated in the Kafue Trough, a sedimentary basin filled by the Permian-aged Karoo sequence, overlying metamorphic basement rocks; it is located to the west of Lusaka and extends westward into the Barotse Basin.

The company has to date identified six geothermal energy targets including Bweengwa River, on all of which it is conducting geothermal exploration.

Peter Vivian-Neal, the CEO, commented: “Results obtained to-date continue to provide confidence that Bweengwa River has the characteristics of a viable geothermal resource for power production”.

“The current model of a 10MW or greater, power project, to be generated using binary technology, represents a significant step towards the company’s objective of producing geothermal power.

“Ultimately, geothermal power may provide a valuable component in Zambia’s drive to diversify sources of energy, increase generation capacity and the distribution of productive power as well as the ‘power to empower’ the community.”

The surface manifestations of the Bweengwa River Geothermal Resource Area include three groups of geothermal springs that extend over 9km and lie on the southern bounding fault of the Kafue Trough.

The resource area is 35km north of the Southern Province town of Monze and 200km from Lusaka.
