Mining for Power: Uranium Mining in Baker Lake Nunavut
Mining for Power: Uranium and the Community of Baker Lake, Nunavut Elaine Wang, University of Vermont (prepared for ENVS 295, Dr. Saleem H. Ali) December 2006 Three representations of the Kivalliq District, Nunavut Clockwise from upper left: project map released to the media by Titan Uranium; satellite image from Google Maps; caribou ranges mapped by Beverly-Qamanirjuaq Caribou Management Board “The Kiggavik Project near Baker Lake never went ahead. It is possible that, because of changing market conditions and the superior ore grades in neighboring Saskatchewan, 1989-90 had provided a window of opportunity for its development that was never to be repeated.” -Robert McPherson 2003, New Owners in the Own Land adapted from Cameco Corporation, 2006; not constant dollars Introduction In a plebiscite held on March 26, 1990, residents of the hamlet of Baker Lake (in what was then the District of Keewatin, Northwest Territories, now the District of Kivalliq, Nunavut, Canada), voted overwhelmingly against the development of a uranium mine by Urangesellschaft Canada Ltd. (UG) at a nearby site called Kiggavik, part of what prospectors know as the Thelon Basin. As a result, UG never explored its claims. In August of the same year, Bob Leonard, the president of the Keewatin Chamber of Commerce stated, “We are in an economic crisis. The economy in the Keewatin is in a mess. We are totally dependent on government spending and there’s no way that can continue.”1 The opening quote by Robert McPherson, a mining consultant in the Nunavut land claims negotiations, suggests that as recently as 2003, uranium mining near Baker Lake was, for many reasons, considered a non-option. -

2018 Yellowknife Geoscience Forum Abstract and Summary Volume
2018 Abstract and Summary Volume Cover photograph Carcajou River, NWT; Viktor Terlaky, Senior Petroleum Geologist at the Northwest Territories Geological Survey The picture was taken following a rainstorm along Carcajou River, NWT, which resulted in a spectacular rainbow across the river valley. In the background are outcrops of the Late Devonian Imperial Formation, interpreted to be submarine turbidite deposits. The light bands are sandstone bodies intercalated with the darker shale intervals, representing periodic activity in sedimentation. Compiled by D. Irwin, S.D. Gervais, and V.

Monsoon system and westerly circulation, to which climate change responds differently, are two important components of global atmospheric circulation, interacting with each other in the mid-to-low latitudes. Relevant researches on global millennial scale climate change in monsoon and westerlies regions are mostly devoted to multi-proxy analyses of lakes, stalagmites, ice cores, marine and eolian sediments. Different responses from these proxies to long-term environmental change make understanding climate change pattern in monsoon and westerlies regions difficult. -

This letter specifically addresses Information Request 1: Potential impacts to cultural use of Lac de Gras Area 1. Please describe how your group used the Lac de Gras area culturally (including the hunting, fishing, trapping, gathering, and travel) before mining started there. As this question pertains to the land use prior to the development of Diavik Diamond Mine, this information was collected and provided to the regulators during the initial environmental assessment of the mine. Please see the attached “Appendix A: Can’t Live Without Work” by North Slave Metis Alliance (1999). 2. Please describe how your group would use and feel about the Lac de Gras area under the following scenarios: a) reconnecting empty pits and underground mine workings with Lac de Gras at closure (that is, Diavik’s current closure plan for the mine), b) putting processed kimberlite into the pits and underground mine workings before reconnecting them to Lac de Gras (that is, the proposed activities for this environmental assessment), c) putting processed kimberlite into the pits and underground mine workings and not reconnecting them with Lac de Gras. During a community meeting, NSMA members expressed that their interest was to have the Diavik mine site (not just the pits) return to pre-development condition as much as practicable, in such a way that the area would be the cleanest and safest environment possible for humans and wildlife. -
