It is the researcher Tobias Bauer in Ore Geology at Luleå University as the project "Multiscale four-dimensional Geological Modeling of Gällivare area" to the challenge. One might think that such a known deposit that Malmfälten should be genomprospekterad and well documented but new technologies and creative ways of thinking, new tools in the process of defining ranges of the ore body deep underground.

- By reconstructing the geological history and especially the structural development of the region, we try to understand the geological evolution of the ore deposits from their formation to the way they have been deformed into its present form and position, says Tobias Bauer, while he rotates the vibrant color model on the computer screen.
The method is also used to find new deposits. By studying the continental appearance and movement through time, one can get a pretty good indication of where to find more ore bodies.
- If you understand how ores once was created, it is easier to find new sights, says Pär Weihed, Professor in Ore Geology at Luleå University of Technology.
The mountains and the ore in the area of Malmfälten was created for about two billion years ago in a volcanic environment at the edge of an ancient continent.
The project "Multiscale four-dimensional Geological Modeling of Gällivare area" is financed by Vinnova, LKAB and Boliden within the Strategic Innovation Programme Mining and Metal Extraction.
