Mineral Potential Evaluation Section Reports

Listed below is a table of published and open-file Mineral Potential Evaluation Section reports since 1976. Many of these projects are available digitally for download as seen in the 'Link' heading farthest on the right. In addition, by clicking on the project's 'Link' there is general information about the project. If there is no digital data available there is an email link to contact us for more information. 

If you would like to search for projects spatially you can download the following GIS shapefile which includes an ArcGIS layerfile and metadata. The shapefile attributes include a URL to hyperlink to project webpages to download data where available. If you do not have GIS software you can download ArcGIS Explorer for free to load in the shapefile. 

This webpage is partially based off a pdf document that lists mineral potential related publications current as of 1997. The document is still available here for reference.
