Established in 1995, GAP is an independent, Johannesburg-based geoconsultancy which focuses on geophysical mapping applications in minerals prospecting, geotechnical and hydrogeological investigations. Broad-spectrum skills include litho-structural mapping and target generation exercises in mineral exploration, and the delineation of “loss-of-ground” features within the mine lease area. Secondary areas include site investigations for engineering geology investigations and aquifer delineation for village and mine water supply purposes. Niche-area expertise relates to the interpretation of high-resolution airborne surveys and high-resolution seismic surveys, both of which were pioneered by GAP staff in Southern Africa.
We operate from company-owned offices in the Johannesburg suburb of Greenside, midway between Downtown and Sandton. Core professional staff comprise some 4 geophysicists plus 2 Consulting Structural Geologist associates. The principals have individually up to 40 years’ experience working with or heading multi-disciplinary project teams in West, Central and Southern Africa plus North America.
The company is headed by Consulting Geophysicist Geoff Campbell MBA MSc who has published and presented widely on high resolution geophysical mapping from the air, on the ground and down the borehole. Expertise lies in programme design, matching programme objectives to cost-effective mapping strategies, quality control and, most importantly, integrated interpretation studies. The latter are often undertaken by joint geophysicist-geologist teams using state-of-the-art software to reprocess and analyze geophysical, satellite imagery and surface geology digital databases. Interpretations fuse qualitative mapping and 2D to 3D quantitative modelling, to generate lithological plus structural products and estimates of target geometry plus depth.
