Services
Exploration Surveys
Our exploration surveys utilise aerial lidar to create detailed digital terrain models for prospect evaluation. We assist in planning diamond drilling programmes and infrastructure placement by merging geological data with topographic features. With experience across six continents, we provide accurate spatial analysis to support informed exploration decisions.
Underground Mining Surveys
We conduct underground surveys using SLAM technology and traditional traversing methods for survey-grade precision. Our handheld mobile scanners create 3D point clouds to monitor ground movement and measure development work. These surveys enable accurate planning of excavations and equipment installations in challenging underground environments.
Lidar Scanning
Our lidar scanning services generate high-resolution topographic data for mining applications. This technology penetrates vegetation to map true ground shapes, aiding in exploration and infrastructure planning. We use both airborne and terrestrial systems to deliver accurate 3D models for surface and underground mining operations.
UAV Drone Surveys
Our drone surveys provide rapid data acquisition for large mining sites using photogrammetry and lidar payloads. These unmanned systems safely access hazardous areas and produce georeferenced imagery. We employ collision avoidance technology for underground operations and deliver time-efficient survey solutions.
Stockpile Volume Surveys
We calculate precise stockpile volumes using mobile laser scanning and drone-based photogrammetry. These surveys support operational planning and resource management by tracking material quantities. Our methods ensure accurate volumetric calculations for diverse mining commodities across global sites.

Questions
What mining survey technologies do you use?
We utilise lidar scanning, UAV drones, SLAM technology, mobile mapping systems, and satellite remote sensing for comprehensive geospatial data collection in mining operations.
In which countries do you operate?
We have conducted surveys in over 60 countries across Africa, Asia, Europe, the Middle East, and South America, adapting to diverse geological environments.
Can you survey underground mines?
Yes, we use SLAM technology and traditional methods for underground surveys, providing 3D mapping capabilities for complex subsurface environments through handheld mobile scanning systems.
How do you handle remote site access?
Our drone technology enables safe surveying of inaccessible or hazardous areas, while lidar's vegetation penetration capabilities support accurate data collection in challenging terrain without physical access.
What mining commodities do you survey?
We survey sites extracting gold, iron, lead/zinc, silver, tin, copper, coal, phosphate, stone, gravel, chalk, ball clay, and china clay across surface and underground operations.
How long have you been in business?
We have provided mining survey services since 1982, celebrating 40 years of continuous operation in 2022 with ongoing technological innovation in geospatial data collection.
