Mining and Exploration Activity
in the Region of the 1836, 1837, 1842, and 1854 Ceded Territories

(many of the maps below are formatted for poster size, but can be printed on 8.5X11 paper by setting  the scaling when printing in Adobe Acrobat to "fit to printable area")
The Land

• Gidakiiminaan (Our Earth) Language Map with Mine Sites and Known Ore Deposits. Ojibwe language place names and operating mines, major exploration areas and known ore deposits. Compiled by GLIFWC for the 1842, 1837, and the Upper Peninsula sections of the 1836 ceded territories.
• Major Transportation Networks with Mine Sites and Known Ore Deposits Map. Major transportation networks in the western Lake Superior region and operating mines, major exploration areas (as of September 2011) and known ore deposits. These roads, rail, and shipping networks could be used to transport ore, concentrate, and chemicals used in the mineral processing process.
  
• Known Tribal Resources and Potential Mineral Development Map. The known presence and/or harvest areas of walleye, musky, and wild rice in relation to operating mines, major exploration areas (as of September 2011) and known ore deposits. Compiled by GLIFWC as part of its delegated authority. Wild rice data for the 1854 ceded territory was provided by the 1854 Treaty Authority.

Exploration

• Metallic Mineral Leases and Exploration in the 1837, 1842, and 1854 ceded territories. This map shows areas of mineral exploration and lands that are leased for mineral exploration.
• Mineral Leases and Exploration in Northern Minnesota. This map depicts mineral leasing and exploration in Minnesota in relation to tribal and public lands.
• Mapping Mining Activity in the Lake Superior Basin. This poster gives some examples of GLIFWC's mapping activities of mining activity in the Lake Superior basin.
• The Lynne Deposit at the Willow Flowage.  This map shows known resources in the vicinity of the Lynne deposit.

Mine Impact Analysis

• Using Mapping to Evaluate Impacts of Proposed Mine Projects on Natural Resources in Areas of Cultural Importance. This poster describes techniques for presenting tribal concerns on the impacts of mining from a cultural perspective.
• Methods for Evaluating Indirect Impacts to Wetlands. This poster describes a method that can be used to assess the effects of changes in groundwater hydrology to wetland functions and values.
• Methods for Visual Impact Analysis and Potential Methods for Defining Areas of Potential Effect. This poster describes ways to characterize visual impacts of mining as part of a NEPA process and a Corps Section 106 process.

Mining in the Penokee Range

• The Bad River Watershed Map.The watershed of the Bad River in Bayfield, Ashland and Iron Counties in northern Wisconsin.
  
• Penokee Range Area of Potential Mining Map.  The upper Bad River watershed and the iron deposit within the Penokee (Gogebic) Range. Primary streams near the iron deposit and the major property owners in the area are identified.
• Iron Mining in the Lake Superior Basin. A pictoral flyer that describes the process and some of the impacts of open pit iron mining in the 3-state region of western Lake Superior.
• Geochemical, mineralogical and structural characterization of the Tyler Formation and Ironwood Iron Formation, Gogebic Range, Wisconsin. A report on some aspects of the geology of the Gogebic (Penokee) Range by Lawrence University professor Marcia Bjornerud.
• Bibliography of Papers on the Iron Deposits of the Penokee Range, Wisconsin. An annotated bibliography by Northland professor Tom Fitz of geology papers related to the Penokee section of the Gogebic Range.
• Map of streams that could be filled with mine waste given the provisions of AB1/SB1 as amended February 5, 2013
• Explanation of methods used for calculating streams vulnerable to mine waste fill.
• Map of streams that could be filled with mine waste, showing the which streams are protected because they are trout streams.
