Drilling and Exploration
GeoHydro is a Zambian geological, geo-technical and hydro-geological consultancy company committed to providing a quality service to the mining and water supply sectors. The management team are qualified professionals with over 26 years of experience. This is a Zambian company with an established network of professional associates in the sub-region which it is expanding into. GeoHydro was incorporated in Zambia in 2005 and later opened a branch in Lubumbashi, Congo DR. They have provided services to local and international clients earning a reputation as the preferred local consultant and contractor. GeoHydro is characterised by a high level of professionalism, a highly skilled workforce and state-of-the-art equipment. They are dedicated to the health and safety of employees and equipment.
Mineral exploration services
The initial assessment and appraisal involves an archive data search, desktop studies of potential regions of interest and ground fixing of prospect areas. This is followed by a geological assessment of potential exploration areas and the generation of first pass exploration targets. GeoHydro will manage the exploration project either in full or in a supporting capacity. After geological mapping comes geophysical ground surveys and geochemical surveys (of stream sedimentations, soils, rock chips and trench channels). The drilling is carried out using diamond drills which extracts the drill core from which samples are prepared. GeoHydro can provide supervision of all relevant activities.
Using sophisticated Geographic Information Systems (GIS), GeoHydro gathers data for geological, geochemical, geophysical and geotechnical interpretation. The processes and techniques used include satellite imagery, aerial photographs, map scanning and geo-referencing. Geologists and geo-technicians may be hired from GeoHydro to carry out specific projects.
GeoHydro also provides services to engineering construction work includes geo-technical site investigations for the design of building foundations as well as related diamond drilling activities. In the area of geophysics data processing, the total magnetic field intensity may be obtained using a GSM-19 magnetometer. The induced polarization technique is also used to help identify subsurface materials. GeoHydro has experience in managing groundwater-based rural water supply projects. It also supervises drilling for groundwater and carries out aquifer assessment and evaluation tests. GeoHydro also performs water quality assessments, aquifer pollution vulnerability and susceptibility assessments and environmental impact assessments.
