MCC Projects

Core Objectives

In keeping with the statutory guidance for the program, the projects fall into one of the three objectives:

  1. to improve and extend Minnesota's iron industry

  2. to encourage exploration and development of nonferrous metallic minerals

  3. to enhance Minnesota's industrial minerals industry

Additionally, two other charges have been given to the program:

  1. to encourage research that aims at longer term mineral resources development potential in Minnesota

  2. to ensure that mineral development satisfies the highest environmental quality standards.

Table of Mineral Coordinating Committee Funded Projects

Minerals Coordinating Committee funded projects that have digital data available for display and download are listed below.  This list will be periodically updated when new digital information is uploaded.

This is a sortable table. The default sort is by year. All of the headings can be sorted by clicking on them. To download or display digital data for a project see the 'Link' column. Projects completed by agencies other than the MN DNR (exp., MGS or NRRI) will direct you to their webpage for that specific project. For more information about this page please contact Dennis Martin: dennis.martin@state.mn.us or (651) 259-5405.
