Rapasaari

The spodumene pegmatite deposit of Rapasaari is located in the vicinity of the municipal border between Kaustinen and Kokkola, about three kilometres south-east of Syväjärvi.

The Rapasaari deposit was discovered by the Geological Survey of Finland in 2009. The exploration carried out by the Geological Survey included boulder mapping, till sampling, geophysical measurements, mineralogical and analytical studies and, in 2009–2011, diamond drilling.

Keliber obtained the rights to the Rapasaari deposit from the Ministry of Economic Affairs and Employment at the end of 2014. After this, the company has implemented several diamond drilling programmes in the Rapasaari area.

The main rock types in the Rapasaari area are mica schists and metagreywackes containing staurolite or andalusite in places. The rock types in the area also include volcanic, intermediary metatuffs and metameta-agglomerates as well as mica schists with seams of quartz and sulphide.

The spodumene pegmatite veins are primarily stratibound in the bedrock of Rapasaari. The deposit consists of several pegmatite veins. The thickness of the veins varies from a few metres to tens of metres.
