Exploration in Arctic Finland presents many logistical challenges. Most work is carried out in the winter – with temperatures often below - 20°C – when the ground has sufficient snow cover and is frozen enough to support the weight of the drill rigs.
Located in an environmentally sensitive region, the Sakatti exploration project faced challenges that required an innovative solution to further reduce its environmental and drilling footprint. In Finland, Anglo American’s exploration team, working in collaboration with drill contractors, Oy KATI Ab, was able to come up with a solution. A closed system drilling technique was developed by taking an idea from a Canadian operation and adapting it to the specific conditions in Finland.
