Blötberget Mine Site, Sweden

The Blötberget and Håksberg iron oxide deposits are located in the historic Bergslagen Mining District (Central Sweden) where mining activities have been recorded since the 1600’s. Modern underground mining at Blötberget began in the 1900’s and ceased in 1979 due to low commodity prices. Nordic Iron Ore acquired the Ludvika mines property in 2008 advancing the property toward a restart with renewed exploration suggesting that mineralization may extend significantly deeper to over 1,000 m.

The Paleoproterozoic Blötberget apatite – iron oxide deposit is believed to represent a Kiruna-type deposit that has undergone deformation and metamorphosed to amphibolite-facies grade. The total mined area consists of five main units some of which have been mined to 350 m depth. These units dip toward the southeast at 50o to 55o in the mined out areas near surface before flattening out to ~25o at depth.
