Jericho Diamond Mine
The Jericho Diamond Mine is a dormant diamond Mining, mine located in Canada's Nunavut territory. Jericho is Nunavut’s first and only diamond mine. It is located northeast of Yellowknife, Northwest Territories and is accessible by air all year and by winter road from Yellowknife. The project was mined from 2006 to 2008, and produced of diamonds from of kimberlite mined from the open pit operation. Over $200 million was invested in the development of the Jericho operations including the construction of a per day diamond recovery plant, maintenance facility, fuel farm, and offices and accommodation for 225 personnel. On July 19, 2010 Shear Diamonds (née Shear Minerals Ltd) (), a diamond exploration company focused on the Nunavut region, announced its purchase of the Jericho Diamond Mine. In late 2010, Shear announced that it would take about a year to devise a plan to reopen the mine. Shear began processing the existing recovery reject pile in early 2012, selling the recovere ...

Provinces And Territories Of Canada
Within the geographical areas of Canada, the ten provinces and three territories are sub-national administrative divisions under the jurisdiction of the Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the '' British North America Act, 1867''), whereas territorial governments are creatures of statute with powers delegated to them by the Parliament of Canada. The powers flowing from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibbitt To Contwoyto Winter Road
Tibbitt to Contwoyto Winter Road is an annual ice road first built in 1982 to service mines and exploration activities in the Northwest Territories and Nunavut in Northern Canada. Between long, the road is said to be the world's longest heavy haul ice road and operates for eight to ten weeks starting in the last week of January. Most of the road (85%–87%) is built over frozen lakes, , with the remaining built on over 64 land portages between lakes. Construction and operation The winter road is constructed by Nuna Logistics and RTL-Robinson every January and takes about six weeks to complete. The first vehicle along each season is a Swedish-made Hägglund army-type reconnaissance vehicle designed to float if it falls through the ice; it tows an ice-thickness-detecting sonar. This is followed by road building equipment including "specialized low ground pressure equipment". The road, built extra wide to avoid blockages during blizzards and to allow opposing trucks to pass, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Nunavut
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diamond Mines In Canada
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ekati Diamond Mine
The Ekati Diamond Mine ("Ekati") is Canada's first surface and underground diamond mine. 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%), and the two geologists who discovered kimberlite pipes north of Lac de Gras, Chuck Fipke and Stewart Blusson each holding a 10% stake in the mine, until Fipke sold his share to Dominion. 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 prospecting in the region for almost ten years, having found kimberlite indicator minerals as early as 1985. The Point Lake kimberlite was determined to be uneconomic, but its discovery precipitated one of largest staking rushes in mining history, covering most of the area between Yellowknife and the Arctic coast. There are 156 known kimberlite pipes within the E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bathurst Inlet, Nunavut
Bathurst Inlet, (Inuinnaqtun: ''Qingaut'' Kingaok, Inuktitut syllabics: ᕿᙵᐅᓐ), is a small Inuit community located in Bathurst Inlet in the Kitikmeot Region of Nunavut, Canada. The Inuit name for the community is ''Kingaun'' (old orthography) or ''Qingaut'' (new orthography), meaning ''nose mountain'', which refers to a hill close to the community. Thus, the people of the area are referred to as "Kingaunmiut" (''miut'' - people of). The traditional language of the area was Inuinnaqtun and is written using the Latin alphabet rather than the syllabics of the Inuktitut writing system. Like Kugluktuk, Cambridge Bay and Umingmaktok syllabics are rarely seen and used mainly by the Government of Nunavut. Bathurst Inlet is the traditional birthing grounds of a "key northern species", the large, migratory Bathurst herd of barren-ground caribou. Over millennia, the Inuit, First Nations and Métis depended on the Bathurst Inlet herd for survival. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo- ...
