Purpose

The Lehmann mineral exploration records contain nearly all that is known about mineral deposits in northern Wisconsin. The Lehmann materials will significantly improve the understanding of the Precambrian geologic history of the more remote parts of our state. Access to these materials can facilitate research into the buried Precambrian geology of Wisconsin as well as expedite exploration for mineral resources. It was the intention of the Lehmann Company to make these materials available to the public to support and advance development of Wisconsin?s natural resources.
