Geology

The area of Kaustinen and its surroundings have been known for their spodumene pegmatites ever since the late 1950s.

The first indications of spodumene, a mineral rich in lithium, in the bedrock of Kaustinen were discovered in the village of Nikula in 1959. Since then, the area has been explored in a number of stages spanning the past decades.

Today, the lithium spodumene deposits of Central Ostrobothnia are one of the most important reserves in Europe.
