Ekati
The Ekati Diamond Mine, often simply called Ekati, is Canada's first surface and underground diamond mine and is owned by Burgundy Diamond Mines. It is located north-east of Yellowknife, Northwest Territories, and about south of the Arctic Circle, near Lac de Gras. Until 2014, Ekati was a joint venture between Dominion Diamond Mines (80%), Charles E. Fipke, Chuck Fipke, and Stewart Blusson, the two geologists who discovered Volcanic pipe#Kimberlite pipes, kimberlite pipes north of Lac de Gras. Fipke and Blusson each held 10% stake in the mine, until Fipke sold his share to Dominion. In 2021, Arctic Canadian Diamond Company Ltd. acquired the Ekati Diamond Mine with associated assets and liabilities from Dominion Diamond Mines. In July 2023, Burgundy Diamond Mines purchased full control of Arctic Canadian Diamond Company. History The first volcanic pipe found in the Lac de Gras region was the Point Lake kimberlite, discovered by Chuck Fipke and Stewart Blusson who had been pros ...

Hugo Dummett
Hugo T. Dummett (1940–2002) was a South African people, South African mineral-exploration geologist who is best known for his role in the discovery of the Ekati Diamond Mine in the Barren Lands of Canada's Northwest Territories. Dummett has been described as "the brains, the ideas and the energy" behind the discovery of Ekati, which led to the creation of a new Canadian diamond-mining industry. Career Dummett earned his BSc degree at the University of the Witwatersrand in 1964, and moved to Canada in 1965 and attended Queen's university at Kingston, where he was a star rugby player playing fullback. In 1970, he entered the University of Queensland for graduate work. In 1977, Dummett signed on with Superior Oil to prospect for diamonds in North America, just as the science of using indicator minerals -- pyrope garnets, chrome diopside and chromite—for diamond exploration was being worked out. Superior formed a joint venture with Falconbridge Limited, and the joint venture hired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanism Of Canada
Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes, calderas, diatremes, and maars, along with less common volcanic forms such as tuyas and subglacial mounds. Though Canada's volcanic history dates back to the Precambrian eon, at least 3.11 billion years ago, when its part of the North American continent began to form, volcanism continues to occur in Western and Northern Canada in modern times, where it forms part of an encircling chain of volcanoes and frequent earthquakes around the Pacific Ocean called the Pacific Ring of Fire. Because volcanoes in Western and Northern Canada are in relatively remote and sparsely populated areas and their activity is less frequent than with other volcanoes around the Pacific Ocean, Canada is commonly thought to occupy a gap in the Ring of Fire between t ...

Northwest Territories
The Northwest Territories is a federal Provinces and territories of Canada, territory of Canada. At a land area of approximately and a 2021 census population of 41,070, it is the second-largest and the most populous of Provinces and territories of Canada#Territories, the three territories in Northern Canada. Its estimated population as of the first quarter of 2025 is 45,074. Yellowknife is the capital, most populous community, and the only city in the territory; its population was 20,340 as of the 2021 census. It became the territorial capital in 1967, following recommendations by the Carrothers Commission. The Northwest Territories, a portion of the old North-Western Territory, entered the Canadian Confederation on July 15, 1870. At first, it was named the North-West Territories. The name was changed to the present Northwest Territories in 1906. Since 1870, the territory has been divided four times to create new provinces and territories or enlarge existing ones.

Lac De Gras Kimberlite Field
The Lac de Gras kimberlite field is a group of Late Cretaceous to Eocene age diatremes in the Northwest Territories, Canada. The Eocene (ca. 55-50 Ma) age diatremes of the Lac de Gras kimberlite field support two world-class diamond mines called Ekati and Diavik. Ekati, Canada's first diamond mine, has produced of diamonds out of six open pits between 1998 and 2008, while Diavik to the southeast has produced of diamonds since its foundation in 2003.

Lac De Gras
Lac de Gras is a lake approximately north east of Yellowknife, in the Northwest Territories of Canada. Lac de Gras was the centre of the diamond rush of the 1990s. There are two working, and one closed, diamond mines in the area, Diavik Diamond Mine, Ekati Diamond Mine, and the care and maintenance Snap Lake Diamond Mine. It was called Ekati by aboriginal peoples. The lake is ultraoligotrophic but supports a slow-growing but stable population of some eight species of cold-water fishes, including round whitefish, cisco, and lake trout. Lake trout dominate the lake, both numerically and in terms of biomass. Other native fish species include common whitefish, Arctic grayling, burbot, longnose sucker, and slimy sculpin The slimy sculpin (''Cottus cognatus'') is a freshwater species of fish belonging to the family Cottidae, which is the largest sculpin family. They usually inhabit cold rocky streams or lakes across North America, ranging from the Great Lakes, s .... Diavi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Pipe
A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces. At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and condenses back into a liquid, releasing the latent heat. The liquid then returns to the hot interface through capillary action, centrifugal force, or gravity and the cycle repeats. Due to the very high heat transfer coefficients for boiling and condensation, heat pipes are highly effective thermal conductors. The effective thermal conductivity varies with heat pipe length and can approach for long heat pipes, in comparison with approximately for copper. Modern CPU heat pipes are typically made of copper and use water as the working fluid. They are common in many consumer electronics like desktops, laptops, tablets, and high-end smar ...

Diamond Mine
There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply. Diamonds are also mined alluvially over disperse areas, where diamonds have been eroded out of the ground, deposited, and concentrated by water or weather action. There is also at least one example of a heritage diamond mine (Crater of Diamonds State Park).

Yellowknife
Yellowknife is the capital, largest community, and the only city in the Northwest Territories, Canada. It is on the northern shore of Great Slave Lake, about south of the Arctic Circle, on the west side of Yellowknife Bay near the outlet of the Yellowknife River. Yellowknife and its surrounding water bodies were named after a local Dene tribe, who were known as the "Copper Indians" or "Yellowknife Indians", today incorporated as the Yellowknives Dene First Nation. They traded tools made from copper deposits near the Arctic Coast. Modern Yellowknives members can be found in city and in the adjoining, primarily Indigenous communities of Ndilǫ and Dettah.
