Zambia: Positive results for geothermal explorer

Results from the first major geothermal exploration and drilling programme to take place since the mid 1980s are positive, according to developer Kalahari GeoEnergy Ltd. The company, currently the only major developer active in Zambia, has been targeting the Bwengwa River area of the Kafue Trough, a 14,000km2 Karoo-era extensional sedimentary basin, in an exploratory programme expected to cost $3.5-4m. Initial mathematical simulations estimate that the target could sustain electricity production of at least 10MW, depending on the location of the reservoir, which has still to be precisely determined.
