Emmes

The Emmes deposit is located under the Emmes lake and in the Emmes village in the municipality of Kronoby.

The area has been explored by Suomen Mineraali Oy and Partek Oy in 1960–1982.

Keliber Oy implemented a drilling programme in the south-east section of the deposit in 2014.

The most accurately explored vein of spodumene pegmatite in the deposit is situated under the Emmes lake. The distance between the roof of the vein and the surface of the lake varies between 5–8 metres (average water depth is 1.5 metres).

The spodumene pegmatite vein runs from north-west to south-east with a dip angle of about 60–80 degrees to south-west. The measured length of the vein is 350 metres. The spodumene pegmatite of Emmes consists mainly of microline, plagioclase, quartz, spodumene and muscovite.
