Diamond Drilling - Exploration and Core Drilling Services

Q: What is diamond core drilling?

Diamond core drilling can be done with different methods, of which diamond drilling is one of. In diamond core drilling we use drilling rig that has a rotary drill with a diamond drill bit. With diamond drill we can create precisely measured holes and extract solid rock columns. Diamond core drilling is a very versatile solution which can be used in almost every situation. Kati has a wide variety of different drills with different sample sizes

Professional mineral exploration drilling using diamond drilling mainly in the Northern Europe.

We drill more than 100,000 meters of rock samples every year. Will you be the one to take us to the next level?

Quality and environmental friendliness are the starting points of our diamond drilling

Quality means sticking to the schedules given to us, implementing the work goals according to the customer’s instructions, taking site-specific risks into account and the uniformity of the work footprint. We take care that our drilling units are in good condition and the drilling samples are clean. We also guarantee quality e.g. with 24/7 on-call management and efficient data collection of deviations in the field.

Diamond drilling in rural and urban areas

Diamond drilling is conducted in varying conditions, in the terrain or town centre, so the drill rig has to adapt in many ways. Awkward terrain requires easy mobility, low weight is important with helicopter haulage and tunnels need particularly resilient machine properties.

Diamond drilling is a form of core drilling

Diamond drilling is a form of core drilling which uses a rotary drill with a diamond drill bit attached, in order to create precisely measured holes. Diamond drilling is suitable for almost any working environment. As it is a non-percussive technique, structural integrity is maintained around when drilling.

Diamond core drilling process

In diamond core drilling process we use a diamond bit, which rotates at the end of drill rod. The opening at the end of the diamond bit allows a solid column of rock to move up into the drill pipe and be recovered at the surface. Core drilling is used frequently in mineral exploration where the coring may be even more than two kilometers in depth.

The KATI diamond drill rig is very adaptable for ore prospecting or mining projects

Our established experience with diamond drilling and core drilling is evident with the KATI drill rig, as well as information pertaining to the demands set by a variety of conditions obtained from the field. KATI diamond drill rigs are safe, eco-friendly, high-performance and pleasant working environments. We are also experienced in designing and implementing technical solutions tailored for our customer’s specifications.

Core drilling using the directional Devidrill method

Core drilling is facilitated using our directional Devidrill branching method that allows directing the drill hole in the required direction. Multiple branches can also be made in the drill hole. This is a cost-effective way of exploring a larger area using the mother-hole when the area to be studied lies at a depth of nearly a kilometer or more.

How can we obtain representative core samples?

A representative core sample is vitally important for e.g. determining ore content and rock characteristics. Making careful choices, such as the use of drilling additives, the samples can be protected from washing and therefore improve sample yield percentages. We study the additives carefully and choose the best for the application, and those that put less strain on the environment. Other tool selections assist in obtaining good samples. All these factors combined with the high competence of the rig operator ensure favourable results.

Core drilling as part of mineral exploration

In the modern world our demand for different minerals is increasing. Mineral exploration isn’t easy, and when mining companies start to explore for new mineral deposits, it takes time to find a good enough spot for a mine. Modern mineral exploration is usually done by geologists and geophysicists, that have the tools to find mineral deposits. When an interesting prospect is found, it can be further determined by core diamond drilling.

What is diamond core drilling?

Our solution to mineral exploration drilling is diamond core drilling.

Mineral exploration drilling can be done with different methods, of which diamond drilling is one of. In diamond core drilling we use drilling rig that has a rotary drill with a diamond drill bit. With the diamond drill we can create precisely measured holes and extract solid rock columns. Diamond core drilling is a very versatile solution which can be used in almost every situation. KATI has a wide variety of different drills with different sample sizes (see the chart at the top of the page).

The benefit of using diamond drilling technique in mineral exploration drilling

The main advantage of diamond core drilling is that you can bring a solid core sample to the surface. No other drilling technique can offer a more accurate profile of the mineral composition at each depth. Using KATI’s Devidrill branching method that allows directing the drill hole in the required direction. Multiple branches can also be made in the drill hole to cover a bigger area cost effectively.
