Radium Mine
''Radium Mine'' is a painting made by Canadian artist A.Y. Jackson when he visited the mine-site of the isolated Radium mine at Port Radium, Northwest Territories, in 1938. Jackson was a friend of prospector Gilbert LaBine, then the mine manager, and flew to the site with him. Significance When the painting came up for auction on November 22, 2012, it was described as "historically significant". The painting was held privately by the LaBine family, prior to the auction, and had been available for public viewing only once. It was expected to sell for as much as $300,000 CAD. Second painting Jackson is known to have composed several other paintings during his many visits to Port Radium. It was purchased by a private owner, whose estate donated it to the National Gallery of Canada in 1939. Art historian John O'brian, an expert on Jackson's work, said he had been unaware of the existence of the painting. Extra interest in the painting was triggered by the mine being the prime s ...

Canadian
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radium
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Port Radium, Northwest Territories
Port Radium is a mining area on the eastern shore of Great Bear Lake, Northwest Territories, Canada. It included the settlement of Cameron Bay as well as the Eldorado (also called Port Radium) and Echo Bay mines. The name Port Radium did not come into use until 1936 and at the time it was in reference to the region as a whole. The Eldorado mine site at LaBine Point adopted the name for its settlement in the 1940s and it has generally stuck. Location Port Radium is situated at on LaBine Point on the McTavish Arm of Great Bear Lake. Cameron Bay is situated southeast at and Port Radium Airport is at between the two to the north and consisted of a gravel airstrip next to Glacier Lake. History During a field trip along the east arm of Great Bear Lake in August 1900, James McIntosh Bell of the Geological Survey of Canada noted evidences of iron, copper, uranium and cobalt in the vicinity of Echo Bay. Thirty years later, a prospector Gilbert LaBine discovered high-grade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia One
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, ling ...

Yahoo News
Yahoo! News is a news website that originated as an internet-based news aggregator by Yahoo!. The site was created by a Yahoo! software engineer named Brad Clawsie in August 1996. Articles originally came from news services such as the Associated Press, Reuters, Fox News, Al Jazeera, ABC News, ''USA Today'', CNN and BBC News. In 2001, Yahoo! News launched the first "most-emailed" page on the web. It was well-received as an innovative idea, expanding people's understanding of the impact that online news sources have on news consumption. Yahoo allowed comments for news articles until December 19, 2006, when commentary was disabled. Comments were re-enabled on March 2, 2010. By 2011, Yahoo had expanded its focus to include original content, as part of its plans to become a major media organization.

Gilbert LaBine
Gilbert A. LaBine, (10 February 1890 – 8 June 1977) was a Canadian prospector who, in 1930, discovered radium and uranium deposits at Port Radium, Northwest Territories. He has become known as the father of Canada's uranium industry. LaBine was president of Eldorado Gold Mines (later Eldorado Mining and Refining) from its start in the late 1920s to 1947. He left the company, which had become a Crown corporation in 1944, to prospect for uranium minerals as an independent mine developer. In the 1950s he brought the Gunnar Mine to production at Uranium City, Saskatchewan. Early life and education Adelard "Gilbert" LaBine was born on a farm at Westmeath Township, Renfrew County, Ontario, on 10 February 1890. He studied at the Haileybury Provincial School of Mines. Career Discovery LaBine made his first prospecting strike "in some silver claims near Cobalt" in the Ottawa Valley. He incorporated his own company in 1926 under the name "Eldorado Gold Mines, Limited". At the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Canadian Dollar
The Canadian dollar ( symbol: $; code: CAD; french: dollar canadien) is the currency of Canada. It is abbreviated with the dollar sign $, there is no standard disambiguating form, but the abbreviation Can$ is often suggested by notable style guides for distinction from other dollar-denominated currencies. It is divided into 100 cents (¢). Owing to the image of a common loon on its reverse, the dollar coin, and sometimes the unit of currency itself, are sometimes referred to as the ''loonie'' by English-speaking Canadians and foreign exchange traders and analysts. Accounting for approximately 2% of all global reserves, the Canadian dollar is the fifth-most held reserve currency in the world, behind the U.S. dollar, the euro, the yen and sterling. The Canadian dollar is popular with central banks because of Canada's relative economic soundness, the Canadian government's strong sovereign position, and the stability of the country's legal and political systems.

National Gallery Of Canada
The National Gallery of Canada (french: Musée des beaux-arts du Canada), located in the capital city of Ottawa, Ontario, is Canada's national art museum. The museum's building takes up , with of space used for exhibiting art. It is one of the largest art museums in North America by exhibition space. The institution was established in 1880 at the Second Supreme Court of Canada building, and moved to the Victoria Memorial Museum building in 1911. In 1913, the Government of Canada passed the ''National Gallery Act'', formally outlining the institution's mandate as a national art museum. The museum was moved to the Lorne building in 1960. In 1988, the museum was relocated to a new building designed for this purpose. The National Gallery of Canada is situated in a glass and granite building on Sussex Drive, with a notable view of the Canadian Parliament buildings on Parliament Hill. The building was designed by Israeli architect Moshe Safdie and opened in 1988. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
