Title: DNR Mineral Potential Section Projects Since 1976

Abstract: Spatial (GIS) footprints of published and open-file projects since 1976 sourced from the Minnesota DNR's Mineral Potential Section. Most of the footprints have a URL link to a related online project webpage where a user can download digital data (scanned and OCRd reports, plates, and datafiles). An online list of projects is available at:

Purpose: The GIS data for mineral resource project footprints allows users to complete a spatial literature review of published and open-file projecs in both GIS software and web map applications. The user can link to an online project webpage to dowload digital data such as scanned reports, georeferenced maps, and GIS data.

The DNR's Lands and Minerals Division conducts mineral resource projects in order to perform the following duties:

Mineral Asset Management for School Trust Lands: Identify, describe, and designate School Trust lands that have valuable resource potential for metallic minerals, industrial minerals, and construction aggregates.

State Mineral Lease Administration: Promote and market, on a global scale, the mineral land assets to attract private capital investment to perform the high-cost and high-risk ventures of mineral resource exploration, discovery, and development. Provide technical knowledge of mineral resources and geology before, during, and after the mineral leasing process. Acquire and manage in a spatial Geographic Information System (GIS) format the state mineral lease technical mineral information about the mineral assets and mineral potential. Use that information to prioritize, promote, and protect the state mineral assets.

Represent the Trusts to Protect Trust Mineral Rights During all Land Transactions: Perform mineral potential reviews of all Trust land transactions, usually where the mineral resources are unknown, to identify and protect the high mineral potential areas that are likely to attract private exploration investment in the future. DNR faces conflicting responsibilities, but must represent the best interest of the Trust and protect it from land designations that would diminish or limit the Trust asset value. Trust mineral rights potentially represent billions of dollars of future Trust royalty revenue.

As requested map construction aggregate resources in support of Minnesota Statutes, section 84.94. Learn about the Aggregate Resources Mapping Program at:

Lineage: Generally speaking each project's footprint represents the area extent of a project. If a project footprint had discontinous polygon extents then the polygons were dissolved into one record. Some of these footprints represent specific sample sites (geochemistry surface or core samples) for a project. This was chosen for the footprint to provide more detail in a spatial selection search. There is an associated attribute table with descriptions seen below.

Section 5: Attributes

Overview: PROJNUMBR - Unique project number used to identify a mineral potential project.
YEAR - Year that project/report was published or most recent open-file.
TITLE - Title of project or report.
TYPE 1 - A general project type by primary type of minerals being evaluated.
TYPE 2 - The type of project being conducted such as geochemistry, geologic drilling, geophysics, or geologic mapping.
TYPE 3 - More detail on the type of project, for example if it is a geochemistry project what type of geochemistry project is it? This could be lake sediment, soil, or peat. If project type 2 was geologic mapping, what kinds of maps were created? In this example it could be construction aggregate, construction aggregate & surficial geology.
AGENCY - The agency responsible and/or conducted the project. Most mineral potential projects were conducted by the Minnesota DNR though some were contracted out to the Minnesota Geological Survey.
URL - A URL link to the MPES project to download digital data (reports, plates, and/or data).
ONLINE - Is the project/report online to download? If no, then the project has not been scanned in yet. Hard copies of the project report are available from the DNR's Hibbing Office.
GISPRJDATA - A field that tells if the project or report has more GIS data available for download.
