August 7, 2014 - Exploration Proposed on State Minerals Lease

MMG USA Exploration LLC submitted an Exploration Plan to the DNR on August 1, 2014 for exploration activities to be conducted on one state mineral lease in Aitkin County. The explorer proposes to conduct three types of ground-based geophysical surveys within State Minerals Lease MM-10490. These types of surveys will involve walking on the land with portable equipment. This exploration plan is not requesting approval of drilling activity. The surface land on this lease is owned by private parties. The explorer has proposed a Surface Use and Exploration Agreement to the surface owners. There has been active exploration for metallic minerals not far away within Aitkin County continuously since the year 2000, but never on this state minerals ownership block.

A summary map of the proposed exploration activities is found at the DNR's exploration plan web page at:

July 22, 2014 - Exploration Proposed on State Minerals Lease

Encampment Minerals Incorporated submitted an Exploration Plan to the DNR on July 16, 2014 for exploration activities to be conducted on one state mineral lease in St. Louis County. The explorer proposes to drill 1 to 4 exploratory borings at each of the two drill sites during the winter of 2014-2015 when the ground is frozen. The Explorer plans to drill at an angle from the surface of the adjacent federal land parcel, and the angle drilling may cross into the state minerals ownership underground. The Explorer does not propose to conduct any surface exploration activities on the state mineral lease, except for the use of the existing winter access trail. The company has been exploring for copper, nickel and platinum group elements on state mineral leases in this township since 2008.

A summary map of the proposed exploration activities is found at the DNR's exploration plan web page at:

July 10, 2014 - Exploration Proposed on State Minerals Lease

Kennecott Exploration Company submitted an Exploration Plan on July 3, 2014 for exploration activities to be conducted on 3 state mineral leases in Aitkin County, near the city of Tamarack. The company proposes to drill 10 to 25 exploratory borings between July 28 and December 31, 2014. The company also proposes to do geophysical surveys there. Kennecott Exploration Company has been exploring for copper, nickel and platinum group elements in this area since the year 2000.

June 13, 2014 - DNR Open-File Project 392: Regional Survey of Gold in Till, Cook Area, St. Louis County

Project LeaderDon Elsenheimer

Mineral Potential Project: #392

The DNR is today releasing geochemical analytical results from the silt and clay fraction and magnetic and non-magnetic heavy mineral concentrates from thirty-four (34) glacial sediment samples collected in Northern St. Louis County, at locations where State- or County-controlled surface ownership overlies State-owned or State-administered mineral rights. This is the latest data release for a DNR geological investigation that began in July, 2012, within an approximately 200 square mile area of historical gold and base metal exploration that lies between Cook and Tower.  In this region, an Archean granite-greenstone terrane is overlain by relatively thin layers of Rainy Lobe till and other glacially-derived sediments.  These are ideal geological conditions for using gold grain counts and heavy mineral geochemistry in glacial sediment samples to explore for proximal bedrock mineralization.

The 34 glacial sediment samples were collected in October 2013, and sent to Overburden Drilling Management, Ltd, (ODM) for heavy mineral concentrate (HMC) separation and gold grain counts.  The results of this processing and gold grain analysis were released by the DNR on December 19, 2013 (see this data release for a sample location map). Sample locations were based on initial results from 105 glacial sediment samples that were collected within the project area in October 2012, processed by ODM, and assayed by Activation Laboratories Limited (ActLabs). The DNR released those results to the public on February 4, 2013 and July 2, 2013. 

Today’s data release includes a January, 2014 analytical report from Activation Laboratories, Ltd. (ActLabs) and associated spreadsheet files.  These documents, and a more detailed description of the project, are available at the DNR’s web site.

http://www.dnr.state.mn.us/lands_minerals/mpes_projects/project392.html

Representative sample splits from these 34 samples have been forwarded to ActLabs for assay and geochemical analysis. The results of this pending analytical work will be released to the public in a future data release.  

Note: While the identification of gold grains in glacial sediment samples may bolster the assessed mineral potential of an area, it is not a determinable test (either positive or negative) for bedrock mineralization. This type of geological investigation should be considered only the first step in determining whether there are bedrock gold deposits in the area. The DNR uses this data for land management purposes.

April 17, 2014 - AITKIN COUNTY SAND AND GRAVEL RESOURCE POTENTIAL MAP AND GIS DATA RELEASED

Sand and gravel resource potential mapping has been completed for Aitkin County. A map and related GIS data are now available for public distribution. The GIS data produced for this project includes: sand and gravel potential, survey of gravel pits, geologic field observations, test hole locations, and sand and gravel sampling results. You can access this information by:

Other Notes - A crushed stone resource potential plate for Aitkin County and an associated GIS dataset will be published at a later date.

January 31, 2014 - DNR Open-File Project 394: Test of the SGH Soil Survey Method

Project LeaderDon Elsenheimer

Mineral Potential Project: #394

The DNR is testing the effectiveness of a proprietary geochemical exploration technique in an area of known copper-nickel mineralization in Aitkin County, Minnesota. In case studies outside of Minnesota, the soil gas hydrocarbon (SGH) procedure developed by Activation Laboratories, Ltd. (ActLabs) has delineated mineralized bedrock targets buried under thick layers of overburden by extracting and analyzing organic compounds trapped on surficial sediment. The goal of this MnDNR project is to test the method’s efficacy in an area of known bedrock mineralization that is overlain with layers of both saprolite and clay-rich glacial till. The project combines SGH surface soil sampling with detailed characterization of till and saprolite samples obtained from existing rotosonic drill cores.

In October 2013, the DNR collected surface materials from 152 sample locations and sent them to ActLabs for SGH analysis and interpretation. The samples were located within a grid that was proximal to a previously sampled grid (see July 2, 2013 data release). ActLabs performed the analysis, and provided the DNR the results in an interpretive report dated January 27, 2014. The DNR is today releasing the report, a sample location map, and a spreadsheet with sample locations and related field data. These documents, and a more detailed description of the project, are available for download at the DNR’s website:

http://www.dnr.state.mn.us/lands_minerals/mpes_projects/project394.html

The DNR will review these results in conjunction with those obtained in the first phase of the project, and will write a final report for this project.

December 19, 2013 - DNR Open-File Project 392: Regional Survey of Gold in Till, Cook Area, St. Louis County

Project LeaderDon Elsenheimer

Mineral Potential Project: #392

The DNR is today releasing preliminary results from the processing and analysis of thirty-four (34) glacial sediment samples collected in Northern St. Louis County, at locations where State- or County-controlled surface ownership overlies State-owned or State-administered mineral rights. This is the latest data release for a DNR geological investigation that began in July, 2012, within an approximately 200 square mile area of historical gold and base metal exploration that lies between Cook and Tower.  In this region, an Archean granite-greenstone terrane is overlain by relatively thin layers of Rainy Lobe till and other glacially-derived sediments.  These are ideal geological conditions for using gold grain counts and heavy mineral geochemistry in glacial sediment samples to explore for proximal bedrock mineralization.

The DNR released those results to the public on February 4, 2013 and July 2, 2013. 

Today’s data release includes an ODM report dated December 5, 2013 that documents HMC separation and gold grain count work for the 34 new samples, a sample location  map, and associated spreadsheet files.  These documents, and a more detailed description of the project, are available for download at the DNR’s website:
