During its first full year of production, the Canada’s total landmass1 and the geology of the NWT total diamond output reached 2.5 million carats. Northwest spans over four billion years of the earth’s geologic history. Territories’ second diamond mine, Diavik Diamond Mine, Diamond production became the driving force of the NWT commenced production in December 2002.

Employment at the NWT’s operating mines in 2014 totaled about 3,250 person-years (complete data for 2015 has Diamonds, gold and base metals are the primary focus of not yet been made public). These direct positions induced exploration in the NWT.

As of July 2016, there are four operating diamond mines at The current diamond mining industry plays a significant role various stages of operation in the NWT, namely Ekati, Diavik, in the economic success of the NWT. It accounts for nearly Gahcho Kué and Snap Lake mines. The Gahcho Kué Diamond 40% of the territory’s Growth Domestic Product.

With the commencement of operations at Cantung Mine Diavik alone reached a production milestone of 100 million and Pine Point Mine in 1962 and 1964, respectively, the NWT carats in May 2016. became a significant exporter of tungsten and base metals.

A GUIDE TO THE MINERAL DEPOSITS OF THE NORTHWEST TERRITORIES 3 Mineral Deposit Types in the Northwest Territories This report examines 75 selected deposits of note that host significant mineralization, which are distributed throughout the NWT. This selection is not comprehensive of all the mineral deposits or mineral occurrences in the NWT. The majority of these host undeveloped mineral resources, which have been located from public documents. It is important to note that the vast majority of these property resources are not National Instrument 43-101 compliant (i.e., would not stand up to the economic term “reserves” within the terms of reserves and resources). The variety and style of metallic deposits and showings found in the NWT is as vast as the territory itself. Not included in this publication are the extensive deposits of oil and gas found along the Mackenzie River and Delta area, or the coal deposits and showings along the Grizzly Bear Mountains in the Great Bear Lake area. Discussion of these depos- its is beyond the scope of this publication, and information on these can be obtained from the NTGS (website www.nwtgeoscience.ca), Department of Industry, Tourism and Investment (ITI) of the Government of the Northwest Territories (GNWT). About This Publication This publication has been divided into four sections: gold; silver and base metals; stra- tegic minerals (i.e. lithium, tungsten, rare earth elements and uranium); and diamonds. Each deposit is described by location, current ownership, a brief history of the deposit, and geology, along with documented exploration or production details. Information for each deposit is referenced, and is publicly available. Any dollar amounts quoted are Canadian dollars unless otherwise stated. For the sake of clarity, and precision this publi- cation has an effective date of July 31, 2016. Corrections and Updates Corrections, updates, and comments for the mineral deposits listed are welcomed by the Mineral Resources Division (MRD) of ITI (GNWT). The accuracy of the corporate information listed with each deposit is as current as could be reasonably obtained during the editing of this publication and has been verified as of July, 2016. Deposits for which no current ownership could be found are listed as such, but this does not mean that the area surrounding such deposits is open for staking. Such information can only be obtained by contacting the Mining Recorder’s Office. This information, along with other contact information, is found in Annex 3. Electronic Information and Disclaimer Some of the information in this publication is from company websites (listed with each deposit). To the best of the editor’s ability these links have been checked for validity, content, and information. The website www.sedar.com has also been used to research public securities documents and information filed by public companies.
