December 2019 - Initial Project Data Release Documents

The DNR released the initial results from the DNR Corescan Project in December 2019.  The data release included more than 180 documents created by Corescan and delivered to the DNR in October 2019; supporting documents created by the DNR, and historical exploration data for the thirty-two scanned drill cores.
The initial set of project documents have been organized by Focus Area and released in five focus area-specific zip files below (along with a sixth data release of general project results). The entire set of documents released on December 11, 2019 can be downloaded in single large zip file: Initial data release package 

December, 2019 - DNR Corescan Project Video Series

In October 2019, the DNR and Corescan organized a seminar in conjunction with the initial release of DNR Corescan Project data. The presentations covered the following topics:

  • Introduction to the DNR Corescan Project
  • Introduction to Hyperspectral Core Imaging
  • Focus area selection & significance
  • Project methods
  • Summary of initial project results
  • Coreshed practicum

The seminar presentations were recorded and are available along with PDF versions of each presentation on the Video Series page.

Project Abstracts and Presentations, 2019

The DNR is releasing an extended abstract and a poster presentation that provided preliminary results from the DNR Corescan Project at the 65th Annual Meeting of the Institute on Lake Superior Geology, held May 8-9, 2019 in Terrace Bay, Ontario.


Elsenheimer, Don, Deyell-Wurst, Cari, and Fonteneau, Lionel C (2019) Hyperspectral Imaging of Bedrock Core from the Minnesota DNR Drill Core Library: A New Tool for Archival Preservation and Mineral Exploration.

Abstract and poster presentations


Preliminary results from the DNR Corescan Project were also discussed in a presentation by Lionel Fonteneau, Brigette Martini, and Don Elsenheimer at the September, 2019 Australasian Exploration Geoscience Conference (AEGC).

Corescan Project Raw Data Cubes

Raw imaging data were collected for each of 1,622 core boxes during the core scanning phase of the DNR Corescan project. These raw, unprocessed data include hyperspectral imaging, RGB photography, and laser profiles organized as data cubes totaling nearly three terabytes (3 Tb). Files are spatially referenced BIL format, compatible with various remote sensing and GIS software packages.

Interested users are invited to contact [email protected] to arrange for data transfer using a user-provided storage solution, such as an external hard drive.  Users can also access the processed project data via Coreshed, which provides analytical and file management tools along with the imaging data.  See Coreshed Data Access for more information on that solution.
