Circum Minerals – Danakil

Umvoto Africa was contracted by Circum Minerals from late 2013 to undertake the water resource assessment for the Danakil potash project, involving desktop studies remote sensing analysis and numerical modelling; weather station installation and hydroclimatological monitoring; and the drilling and testing of five 75 – 165m deep, high-yielding (>50 litres/second), wide-diameter production boreholes into the Dogua Mountain alluvial fan primary aquifer system (along with five exploration/ monitoring boreholes.

A month-long aquifer stress test conducted in October – November 2016 resulted in 600 000 m3 of groundwater being abstracted from the production boreholes, with subsequent modelling indicating a substantial and sustainable supply.
