KATI - Diamond Core Drilling and Down Hole Surveys


OY KATI is a Finnish company, specialising in diamond core drilling. We are one of the largest operators in the Scandinavian diamond mining field. Our goal is to provide our clients with high-quality data on the geology of an area in an efficient and reliable manner. In addition to drilling, we carry out measurements with modern devices to offer valuable additional data to our clients.

We have extensive experience working in demanding conditions, from underground mines to superterranean sites and from arctic regions to the Sahara. KATI takes responsibility for the effects of mining on our environment.
Our operations have been based on sustainable development principles for years, and are certified to comply with the requirements of the ISO 14001 environmental management standard. We facilitate the implementation of our clients' projects by taking the interest of nature carefully into consideration in our drilling work.
We supply drilling units for all types of terrain, as well as accurate surveys, and our employees receive continuous training in occupational safety, first aid and fire work.

Diamond core drilling and surveys
We produce high quality information from underground in an efficient and trustworthy manner. Our principal product is drill core, and we aim to achieve prompt delivery of this product to the customer every time. Our objective is to provide a reliable and first-rate service to the industry, making us leaders in drilling efficiency.
Our drill rigs operate mainly on surface drill sites, but we also have plenty of experience in working in underground projects. In 2007 we employed nearly 70 people.

Our customers consist of various major and junior exploration and mining companies, including the dimensional stone industry, environmental research institutes, power companies, Geological Survey of Finland, municipalities and other public-sector organisations. KATI headquarters are located on the west coast of Finland, about 150km south of Oulu.
Borehole surveys for additional data
We carry out surveys with advanced equipment to achieve accurate results, this includes Maxibor and Deviflex tools. With these surveys we can find out the inclination and possible deviation of the proposed direction of a borehole.
Down hole surveys
By using inclination and deviation surveys, the location of the drill hole in 3D can be located extremely accurately. In addition to these surveys, the water pressure tests may show the integrity of rock.
Core drilling units
We have designed and built our own modern core drilling units as the foundation of our extensive experience. Our drill rigs are efficient, suitable for all kinds of terrain and they minimise the impacts of our work on the environment. Additionally, they offer our employees safe and comfortable working conditions.
Fly drilling units
Underground rigs are included in our selection of drill rigs, as well as helicopter transportable fly rigs. Fly rigs are a good option when you need to reach a remote destination. They can also be transported by ATVs or snowmobiles.
Environmentally friendly core drilling
In the design and manufacture of drilling units, we have paid particular attention to environmental friendliness, operation in arctic conditions and occupational health and safety. The KATI drilling cabin is enclosed and so provides good working conditions for operators, even in tough conditions. Nearly all rigs are rubber tracked, which provides easier moving and minimizes the stress to environment.
Drilling contractors
One of the cornerstones of KATI's success is the highly competent personnel with a strong sense of responsibility. Our employees receive continuous training in occupational safety, first aid and fire work. Thanks to the modern drilling equipment and the high morale of the employees, our crew achieves excellent drilling results.
