Measurements
Accurate Borehole Surveys for Precise Positioning and Orientation
Timely and precise borehole measurements are essential for mine planning and ore assessment. Our measurement team performs deviation and azimuth surveys during drilling or, when needed, in existing boreholes — ensuring accurate positioning of drill core samples and potential ore deposits.

Hydrology
Hydrological Services During Drilling
Water management is crucial for controlling the environmental impact of mining projects and for planning infrastructure construction. We offer hydrological investigations — such as water loss measurements to assess bedrock integrity and conductivity — which can be efficiently carried out during drilling operations. Our services provide valuable data for flow modeling and the planning of other hydrological works. In addition, we install pumping and monitoring wells as well as sensors, such as piezometers, for monitoring water pressure and levels in cooperation with the client.
Modern Measurement Technology
Intelligent Insights into Bedrock
We utilize advanced measurement technologies and data analytics to supplement drilling data and create accurate geological models to support our clients’ decision-making. We specialize in azimuth surveys to determine the exact position and orientation of drill holes, and our wide range of measurement devices allows us to offer flexible, client-specific services.

More Accurate Measurements
One of our most significant competitive advantages is Continuous North-seeking Gyro technology, which enables highly accurate and reliable measurements in deep boreholes. This provides even greater precision for mineral exploration and mine planning.
Always Ready
Our experienced and well-trained measurement team is proficient with a broad range of modern instruments. We have a dedicated six-person measurement team on call 24/7 to serve our clients.

Reliability Guarantee for Measurement Results
We provide a reliability guarantee for our measurement results, confident in the expertise of our team. Our clients can compare our performance to industry standards and trust that KATI will continue to be their reliable partner in subsurface investigations.
