Purnu no. 1 (Puolalaki)
LKAB discovered the gold deposit in the 1980s and drilled in total 25 diamond boreholes. The middle section of the deposit is not drilled, because of the terrain conditions. The outer parts have historically been estimated to approx. 100,000 tonnes at 4.62 grams gold per tonne and approx. 62,000 tonnes at 2.38 grams per tonne. The area is geophysical ground measured. Further drilling is planned when all historical material is compiled.
