In addition to diamond drilling, we take various kinds of measurements, such as measurements of the in situ-stresses in rock, or the actual route of the borehole. The measurements enable us to locate the ore deposit very precisely. We can also branch the hole by drilling one or more side-holes from the main hole. This will allow us to target the resources to the desired location.

Our measurement services complement the information about the borehole and provide us with valuable knowledge concerning the ore deposit.

• Ez-Dip and Devi Dip inclinometers measure the inclination of the holes
• Deviation survey to determine the true path and end point of the hole
• Detecting start azimuth of the hole with tachymeter
• Water pressure tests specify the integrity of the rock
• Core orientation

Our deviation survey instruments are following:

Latest option in KATI survey tool selection is SPT GyroTracer, which is commonly used in oil and gas industry. Now this top precise northseeking gyro is available also for mining and exploration industry.Unlike the other survey instruments, GyroTracer also detects the start azimuth of the hole, so there is no need for additional instruments to get exact start azimuth for precise deviation information.

Case: Kevitsa Winter 2009

KATI carried out a survey project for Kevitsa Mining Oy in Sodankylä, which is located in Finnish Lappland. The purpose was to find out deviations of old drill holes. Survey tool used was GyroSmart, and surveys were carried out without drill rig on site. This method made it possible to complete project quickly. See picture of survey work below.
