Subsurface evaluation technologies + services
Digital Surveying combines accurate borehole positioning with high-resolution in-situ logging, quality assurance and integration-ready answer products for mining, infrastructure, water and environmental decisions. Geoscience done right, across Africa and beyond.
Digital Surveying is a South African subsurface evaluation company. Six connected service streams convert every metre drilled into positioned, decision-ready knowledge: Digi-Surv™ positions the borehole, the four Digi-Log™ streams measure the formation, and Synthesis™ integrates the evidence for mining, infrastructure, water and energy clients across Africa, the Middle East and Asia.

From raw counts to decisions
Dedicated petrophysicists and data scientists reduce, validate and interpret every dataset we acquire, then integrate it with your core, assay and structural models.
Petrophysics
Data reduction and interpretation workflows that validate and enhance acquired in-situ datasets: density, magnetic susceptibility, conductivity, natural gamma, porosity and permeability.
Data science
From manual log interpretation to semi-automated lithology blocking and machine learning classification, integrated into 3D resource and structural models.
Supported directional survey and core orientation products from Axis Mining Technology, Hexagon and Veracio, with technical support that answers the phone.

High accuracy alignment for all-angle surface or underground rigs gets you drilling on target faster.

Exceptional performance with extreme reliability for high accuracy survey requirements while cutting rig downtime.

Magnetic EMS remains the most widely used directional survey method. We keep the best options available for your project.

Accurate core orientation should be a simple process. The industry's most advanced options, matched to your needs.

What drives us is close collaboration with every stakeholder to support evidence-based, informed decision-making throughout the project lifecycle.
Two things make that possible: integrity, in our conduct and in our quality-assured outputs, and innovation, in how we perform and how we collaborate to advance your development goals.
Please pass thanks on to your employees who work very hard on site here and have delivered excellent logging, working both day and night shift, which enables the drilling progress.
