Geologist analyzes 1 million feet of rockMilestone lays groundwork of Minnesota’s non-ferrous mining potential.

It takes perseverance, patience and a well-trained eye to closely analyze and document the mineralization in drill core samples taken from rock formations.
On March 11, Mark Severson completed the visual analysis of 1 million feet of drill core with copper-nickel-platinum group element mineralization. Severson is a geologist at the Natural Resources Research Institute, at the University of Minnesota Duluth, and he began this task in 1987.
“This is a great accomplishment,” said Steve Hauck, NRRI deputy director of the Economic Geology Group. “No other geologist has completed this feat in the Duluth Complex and no one else will do it again for quite some time.”
What it gives Minnesota is a roadmap for the valuable minerals beneath our feet. The Duluth Complex is a rock formation that arcs north from Duluth and northeast toward Hovland, Minn. Reflecting its name, it is a complex mosaic of valuable minerals that formed some 1.1 billion years ago as volcanic magma rose through the earth’s crust.
Severson’s documentation helps mineral exploration companies understand the geology of this area of Minnesota, as well as the copper, nickel, platinum group element mineralization and other mineral deposits. This information is the backbone of the state’s evolving non-ferrous mining industry.
