COMPANY PROFILE

GeoActiv is a geological consulting and contracting business, based in Johannesburg, South Africa.  Since 1999 we offer a broad spectrum of geological services to the mineral industry in Southern Africa as well as internationally. The founders and share holders are professional geologists with many years of experience in various geological disciplines and they ensure confidential and reliable services of a high standard.

Our staff of experienced professionals has been closely involved with mining operations, target generation, mineral exploration and prospect evaluation in Southern Africa and abroad.  We also draw on a large base of contract geologists with special skills and experience, as may be needed for specific projects.  

GeoActiv is in close association with businesses related to mining, such as environmental management, land surveying, remote sensing and ground water management.

We offer a comprehensive and integrated ("one-stop") geological service that covers all aspects of the mineral industry, fully compliant to our client's needs. Our team can manage and conduct small to large projects, from core shed management and core moves, to managing large drilling projects and compliant mineral resource reports
