August 26, 2013: The mineralogy report is now complete. The Center for Advanced Mineral and Metallurgical Processing (CAMP) in Butte, Montana was sent fourteen core samples in April. The samples were photographed, crushed and then sieved in order to prepare and analyze using automated scanning electron microscopes and software. The purpose of the study was to determine the iron, manganese and ore mineralogy.
The study confirmed the physical and chemical analysis of the ore and leads us to believe that separation and processing should get the valuable minerals to a high grade.
This study was very important and had to be done, as we move to the next stage - a processing test. We have authorized sending samples to laboratories to mimic the processing phase. The samples will be crushed and processed to separate the iron and manganese from the quartz and ultimately the goal is to see the quality of the final processed ore material. That will help us to better update the economic report of the mining project and to see if we can achieve battery grade manganese.
We are still studying various techniques for extraction of the ore.
While this project is seeming to take a lot longer than we anticipated, it's important that all steps be taken to assure this mineral extraction project is viable and environmentally and economically feasible.
April 9, 2013: New core samples were taken in the fall of 2012 and early winter. The samples will expand our resource model and give us a closer understanding of the value and the amount of manganese, iron and silica we have at the Manganese deposit by Emily MN. The analysis is still not complete, but the economic study has begun with the knowlege of the new resource model. We have also begun the minerology to see how best to process manganese and iron once it is extracted. We anticipate several more months of study.
Environmental Responsibility Committee meeting held February 22, 2012:
The Environmental Responsibility Committee (ERC) made up of local residents, lake associations and Emily City representatives met once again on Wednesday, Feb. 22 for a recap and review of the demonstration project. While the 'Operations' of the demonstration ended in the fall, studies of the demonstration and monitoring have been ongoing.
Cooperative Mineral Resources is currently taking the next six months to review data and understand varying techniques that may be used in a commercial operation if we decide to move forward with that.

Recent Core Sample Data (taken in late 2011)
December 2011: Extra core samples were taken in September and October so CMR could learn as much as possible about the geology of the manganese site. Those samples are being tested at this time. Barr engineering is also working to complete white papers on the Demonstration findings and facts.
August 5, 2011: Extraction phase of Demonstration Complete... Operations shut down for study (for full press release, click here)

Links to photos of varying grades of Manganese cut from the ore taken from the demonstration site in Nov/Dec. are available The Coleraine facility reported this:
They cut different grade samples from areas in the ore.
Photograph #1474 represents an average- average plus grade of ore, with an analysis of 19.81% MnO2
Photograph #1478 represents a higher grade 'darker band' in the ore, with an analysis of 42.64% MnO2
Photograph #1481 represents darker, high grade, 1/8-1/4inch chips , in the ore, with an analysis of 87.71% MnO2
November 17, 2010: DEMONSTRATION PROJECT BEGINS!... Initial run late yesterday pulls valuable manganese from 360 feet below the ground surface. Click here for full story
November 9, 2010: An estimated seven hundred area residents toured the site of the manganese deposit on Saturday, October 27 as part of a special community open house. Cooperative Mineral Resources (CMR), a subsidiary of Crow Wing Power, is preparing to start their bulk sample demonstration project to show a new way to extract manganese. The open house gave people a chance to learn more about the project, the potential opportunity for the community, and the work that has been done to create the plan for this project. The demonstration project is expected to commence during the week of November 10. Open House Press release
August 18, 2010: Cooperative Mineral Resources has offered to sample all wells in the City of Emily, so that residents know the level of manganese and iron in their wells. The sampling is only being offered to help area residents learn about their particular well. Questions and Answers concerning area well sampling is available here.
August 3 , 2010: Great News! EPA approves final permit needed for demonstration project. Today the Environmental Protection Agency approved an Injection Well Permit, allowing Cooperative Mineral Resources (CMR) to move forward in its plans to conduct a small bulk sampling demonstration project. The five acre manganese site is now under rennovation and construction to prepare the site for the proposed mid-September demonstration.
August 2, 2010: Letters were sent to landowners within one mile of site to offer free well testing. CMR has been asked by the City Council and Planning and Zoning to provide free well testing to any landowner within one mile of the manganese site. Those letters were sent on August 2.

MAY 26, 2010: Yesterday the Minnesota Department of Natural Resources (DNR) announced their Record of Decision on the determination for a need for an Environmental Impact Statement for the proposed Bulk Sample Manganese Mineral Extraction Demonstration Project slated for later this summer.
The DNR has determined NO EIS IS NECESSARY. Now the project can move forward to obtain necessary permits and work with the City of Emily for ordinance amendments. The demonstration bulk sampling project is slated for September pending all necessary permits, etc. are obtained in a timely manner.
The Public comments on the Environmental Assessment Worksheet are now publically available as is the DNR Record of Decision (below).
