Laiva is situated in Ostrobothnia, outside Raahe, in the midst of the Finish mining belt, which stretches from Raahe by the Baltic Sea across Finland to Lake Ladoga in Russia. Laiva’s bedrock is dominated by intermediary to basalt volcanic rock and quartz diorites. The mineralization was formed when pressure and movement in the earth crust opened up cracks into which warm, circulating movements brought gold and other elements. As the geochemical circumstances were favourable and the liquids were cooled down, the gold felled out and formed the mineralization that we see today.These can be found in vertical zones and pathways of quartz running from east to west. Test mining and concentration has shown that more than 90 per cent of the gold can be mined based on fairly simple technology.
