Surveying programs for mining companies
We pride ourselves in providing accurate Gyro survey information, allowing drillers to navigate to a target with precision. Real-time Gyro tool face, inclination and azimuth readout allows for accurate motor and wedge orientation..
Surveying for inside RC rods
Our INS Gyro or GyroSmart are magnetic tools capable of surveying inside the drill string.
Horizontal drill-hole surveying
Manual and mechanical methods are employed to push our precision Gyro surveying instruments horizontally.
We measure deviation in blast holes, both up-hole and downhole; improving blast efficiency and safety for underground and surface mining companies.
Grade control surveying
We provide high-precision Gyro or EMS directional survey information in real time for grade-control drilling programs, minimising rig downtime and providing on-site directional data.
Borehole radar acquisition
GeoMole our borehole radar JV partner has developed innovative and ground-breaking borehole radar technology, which is proven to delineate ore bodies. The GeoMole radar propagates up to 50m from your drill-hole, giving 3D images of ore-bodies, lithology, dykes, faults and voids.
Digital Surveying uses world-class technology to accurately map the trajectory and give reference to borehole radar delineation.
Surveying raise boreholes
We position raise boreholes ensuring the pilot hole hits the target or can be found underground by surveying inside the rods or open hole as drilling progresses.
