Table of ContentsDiamonds in Canada?Throughout the 20th century most people would never have thought about being an important producer of. 1 Most people's knowledge of diamonds was fixed on mining operations in and diamond trading centers in.All of this started to change in 1991 when two geologists, Chuck Fipke and Stewart Blusson, found evidence of diamond-bearing pipes about 200 miles north of Yellowknife, Northwest Territories. One of these pipes was developed by BHP Billiton into the EKATI Diamond Mine, which produced Canada's first commercial diamonds in 1998.

Diavik was the second diamond mine to open in Canada, producing its first diamonds in 2003. The pipes being mined were originally exposed on the bottom of Lac de Gras. Dikes were built around the pipes, and the area to be mined was dewatered by pumping. This created an island which now allows mining below the level of the surrounding lake. Photo courtesy of.

Canada: A Major Diamond ProducerThe EKATI discovery launched one of the most intense prospecting rushes in the history of. Thousands of prospectors travelled to the Canadian North. Instead of bringing wooden stakes with them to mark their claims, they all intended to purchase stakes near their destination.

So many wooden stakes were being purchased by the miners that local lumber companies were unable to meet the demand!By 2006, three major mines were producing over 13 million carats of gem-quality diamonds per year. This placed Canada as the in the world. 2 The activity associated with the production of brought billions of dollars in commerce to the economy of the Canadian North.Related.

Data from USGS Mineral Commodity Summaries. EKATI Diamond MineThe EKATI Diamond Mine is Canada's original diamond mine. It was opened in 1998 by BHP Billiton, Canada, Inc. And is owned by Dominion Diamond. It was initially an open-pit mine but mining moved underground as the surface mineable ore was depleted. EKATI is located about 200 miles north of Yellowknife, and about 100 miles south of the.

Diamonds from the mine are sold under the Aurias trade name and verified through the Canadamark service.The underground reserves currently being mined at EKATI are expected to be depleted by 2020. The company is working to develop a new open-pit operation in additional reserves on an adjacent property. These additional reserves are thought to be adequate to extend operations for about ten more years. Diavik Diamond: Diamonds from Diavik are some of the most valuable in the world. They are relatively large diamonds with exceptional clarity. Diavik Diamond MineDiavik was the second diamond mine in Canada to produce diamonds.

Rio Tinto PLC owns a 60% stake in the mine through their Diavik Diamond Mines subsidiary. Dominion Diamond Mines ULC owns a 40% stake in the mine through their Dominion Diamond Diavik Limited Partnership. Operations at the mine are managed by Diavik Diamond Mines.Diavik is located about 200 miles north of Yellowknife, Northwest Territories and about 120 miles south of the Arctic Circle. Supplies are delivered via an ice road that connects Diavik to Yellowknife. The Diavik Stars of the Arctic: In October, 2018, Rio Tinto and Dominion Diamond Mines announced that three spectacular diamonds produced from the jointly-owned Diavik Mine would be sold at auction. The collection includes three named specimens: 'Vega of the Arctic', a 177.71-carat diamond which they report is 'one of the largest and most valuable gem-quality rough diamonds ever produced in Canada'; 'Altair of the Arctic', a 59.10-carat diamond; and, 'Capella of the Arctic', a 24.82-carat yellow diamond.

Capella is an extremely rare find. In an average year, the Diavik mine only produces about five large, representing less than 0.001 percent of annual production. Photo by.The pipes being mined were originally on the bottom of Lac De Gras and were discovered by drilling through the ice.

To mine the pipes a dike was built around them, then the water was pumped out. Open-pit mining then began on the lake bottom, with the mine being kept dry by pumps maintaining a groundwater cone of depression.The first ore production occurred in 2003. Production moved underground in 2010 as the surface-mineable ore was depleted. The transition from surface to underground mining was completed in 2012.

That same year Diavik completed construction of a 9.2-megawatt wind farm that provides over 10% of the electric power used by the mine.In late 2015 the Diavik Foxfire was unearthed. Aces of the luftwaffe cz. At 187.7 carats, it was the largest gem-quality rough diamond ever discovered in Canada. It is also believed to have formed hundreds of kilometers below the Earth's surface an estimated 2 billion years ago. 552-Carat Yellow Diamond: Dominion Diamond Mines announced on December 14, 2018, that a 552-carat yellow diamond was found at the Diavik Mine, located in Northwest Territories, Canada. They believe that this is the largest diamond ever found in North America. It surpasses the Foxfire, a 187.7-carat diamond, also found at Diavik in 2015, which is believed to be the previous largest diamond found in North America.

Dominion plans to have the stone cut by a master diamond cutter and certified by the Canadamark program. (Rio Tinto PLC owns a 60% stake in the mine through their Diavik Diamond Mines subsidiary.

Image by.In early 2018, Diavik started open-pit mining at their A21 pipe, located adjacent to the company's existing mine at Lac de Gras. The company spent $350 million develoing the pipe, and it is expected to operate in an open-pit mode for abour four years.

3In December 2018, Dominion Diamonds announced the discovery of a 552.74-carat that they believe is the largest diamond ever found in North America. The rough stone measures 33.74 millimeters by 54.56 millimeters.

Dominion plans to have a master diamond cutter examine the stone and plan an optimum cut. They hope that it will yield a Fancy-color main stone of significant size that will be Canadamark certified.Kyle Washington, Chairman of Dominion Diamond Mines, announced the diamond by saying. “The color and texture of the diamond are a unique example of the journey that natural diamonds take from their formation until we unearth them.

Our Diavik Mine has produced some of the most beautiful diamonds in the world, and this one certainly tops the list.”Jericho Diamond MineThe Jericho Diamond Mine was the third diamond mine in Canada and the first in territory. It is located about 250 miles northeast of Yellowknife, Northwest Territories. The mine was opened by Tahera Diamond Corporation and produced diamonds from 2006 to 2008 but the company lost money.

In 2010, Shear Minerals, Ltd. Acquired the property with the intent of bringing the mine back into production.Related. High-Quality Rough Diamonds: Octahedral diamond crystals from the Diavik Mine.

Snap Lake Diamond MineCanada's fourth diamond mine was the Snap Lake Mine, located about 150 miles northeast of Yellowknife, Northwest Territories.

The mine is owned by De Beers, and it was their first mining operation outside of Africa. It was Canada's first completely underground diamond mine. Instead of mining a vertical pipe, the mine follows a kimberlite about 2.5 meters thick that slopes down under Snap Lake at an average dip of about 12 to 15 degrees.The first commercial production at Snap Lake was in 2008. The mine operated for seven years without turning a profit.

The mine was located under a lake and was plagued by a continuous seepage of groundwater into the mine. This water was very costly to collect, pump out of the mine, and handle before it could be released.

In December 2016, De Beers announced that they planned to flood the mine to reduce ongoing pumping and maintenance costs. Production at the mine cannot be restarted without a significant effort to remove the water and return the site to operating conditions. Victor Diamond Mine: An aerial view of the Victor mine from October 2017. Image by Terry Kruger,. Victor Diamond MineThe fifth Canadian diamond mine to open was the Victor Mine located in the James Bay Lowlands of Northern, about 50 miles west of Attawapiskat.

It is an open-pit mine owned by De Beers and the first diamond mine in Ontario. Diamonds were produced from one of sixteen diamondiferous kimberlite pipes on the property. 5Production at Victor commenced in July 2008. The mine was expected to produce an average of about 600,000 carats per year through a productive life of about ten years, with a total production of about 6 million carats of gem-quality diamonds. De Beers stopped mining at Victor in March 2019 and processed the last of the productive ore in May 2019. The mine exceeded its anticipated production by over 2 million carats.De Beers holds mining rights to the nearby Tango diamond deposit a short distance from Victor.

The Tango deposit is smaller, about 1/2 the size of Victor, and might support five to six years of additional mining. Developing the project will require formal support from the First Nation of Attawapiskat. The closing of Victor reduces the chance that De Beers will move forward with Tango.

Much of that success was supported by rich ores, containing high-quality diamonds that could be produced by open-pit mining.

The diamonds produced by these mines were favored by consumers who value diamonds produced from mines that are environmentally responsible and conflict-free. Canadian customers have also patronized that are obviously marketed and marked as a Canadian product.Related:Although exploration for new deposits continues, the pace has dropped dramatically from the original boom. New discoveries in, Northwest Territories, Nunavut, Ontario, and Quebec are being evaluated, and some of them might be developed into profitable new mines.
