GeoGroup

What GeoGroup does

GeoGroup is a South Africa-headquartered provider of specialized geotechnical and exploration services to the mining, civil infrastructure, and environmental industries across the African continent. Founded in 1989 by Dave Rossiter as Geomechanics CC, the group now operates through multiple wholly-owned entities, including Geomechanics (Pty) Ltd, Geomech Africa (Pty) Ltd (a Level 1 B-BBEE contributor), Terra Monitoring (Pty) Ltd, and international operating companies in Botswana and Uganda. Its stated operational footprint spans 22 African countries and is supported by one of the continent's most extensive drilling fleets, comprising 50+ specialized units, including 47 core drill rigs, sonic rigs, and CPTu units.

The group's service portfolio is organized around five integrated core offerings: geotechnical investigations, exploration drilling (capable of depths up to 2,000 metres via wireline and reverse circulation methods), sonic drilling (high-frequency vibratory drilling recovering continuous, undisturbed core in 3-inch and 6-inch diameters), S-CPTu and in-situ testing (including seismic cone penetration testing, electronic vane shear testing, seismic dilatometer, and Lugeon testing), and geotechnical instrumentation supply, installation, and monitoring via the Terra Monitoring sub-brand. Notable technical differentiators include the in-house designed jack-up barge "Jack-Tup" for over-water investigations in rivers, lakes, harbours, and near-shore environments, as well as remote wireless telemetry systems for real-time monitoring of tailings storage facilities and dam infrastructure.

GeoGroup generates revenue through project-based professional services contracts with enterprise and government clients, including major mining houses (TotalEnergies, Rio Tinto, Assmang, Letšeng Diamond Mine, Langer Heinrich Uranium Mine), engineering consultancies (AECOM, Jones & Wagener), and public-sector bodies (Lesotho Highlands Development Authority, Free State Province). Pricing is quote-based and project-specific, with services billed under fixed-price or time-and-materials arrangements on multi-year contracts, supplemented by recurring managed services revenue from instrumentation monitoring. Go-to-market is executed via direct enterprise field sales targeting consulting engineers, mining companies, and infrastructure developers through project-based bidding and relationship-driven business development, with five regional offices in South Africa supporting continental operations.

Core offering

GeoGroup provides specialised subsurface geotechnical and exploration services to civil, mining, and environmental clients across Africa through five integrated offerings: geotechnical site investigations, deep mineral exploration drilling (up to 2,000m), sonic drilling for high-quality undisturbed core recovery, S-CPTu and in-situ testing for soil characterisation, and turnkey geotechnical instrumentation supply, installation, and remote monitoring via its Terra Monitoring arm.

Product overview

GeoGroup is a provider of specialised geotechnical and exploration services across Southern Africa, comprising multiple specialist entities (Geomechanics, Geomech Africa, Terra Monitoring). The portfolio consists of five integrated core service offerings: Geotechnical Investigations (subsurface drilling and testing for civil, mining, and environmental projects), Exploration Drilling (mineral resource drilling up to 2000m depth), Sonic Drilling (high-frequency vibratory drilling for undisturbed core recovery), S-CPTu & In-Situ Testing (cone penetration testing and seismic testing for soil characterisation), and Geotechnical Instrumentation via Terra Monitoring (supply, installation, and monitoring of geotechnical instruments including piezometers and data loggers). These services are offered as an integrated suite enabling turnkey solutions from site investigation to long-term monitoring.
