Uranium Mining In The Elliot Lake Area
Uranium mining in the Elliot Lake area (prior to 1955, more commonly known as the Blind River area) represents one of two major uranium-producing areas in Ontario, and one of seven in Canada. In the mid-1950s, the influx of people to Elliot Lake seeking uranium was described by engineer A. S. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world". Mining activities peaked around 1959 and 1960 to respond to a US military needs for uranium during the Cold War. By 1958, Canada had become one of the world's leading producers of uranium and the $274 million of uranium exports that year represented Canada's most significant mineral export. By 1963, the federal government had purchased more than $1.5 billion of uranium from Canadian producers for export. The opening the mines and the workers they attracted led to the creation of Elliot Lake planned town. US demand slumped in the early 1960s, but the increasing use of nuclear power for electricity-generation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliot Lake
Elliot Lake is a city in Algoma District, Ontario, Canada. It is north of Lake Huron, midway between the cities of Sudbury and Sault Ste. Marie in the Northern Ontario region. Once dubbed the "uranium capital of the world," Elliot Lake has since diversified to a hub for forest harvesting, mine reclamation expertise, and advanced manufacturing. Elliot Lake is now known as a place for affordable retirement living, waterfront cottage lots and as a four-season destination. History Prior to the settlement of the city, a seasonal Ojibwa village extended along the lake's shoreline near the present hospital. The town takes its name from the lake. There is no official record of origin of name; the earliest appearance is on the Dominion map of 1901. Folklore suggest it was named for a logging camp cook who drowned in the lake. The townsite name was approved on August 14, 1952. Elliot Lake was incorporated as a city in 1990. Uranium mining The city was established as a planned community ...

Sudbury Basin
The Sudbury Basin (), also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. The crater formed 1.849 billion years ago in the Paleoproterozoic era. The basin is located on the Canadian Shield in the city of Greater Sudbury, Ontario. The former municipalities of Rayside-Balfour, Valley East and Capreol lie within the Sudbury Basin, which is referred to locally as "The Valley". The urban core of the former city of Sudbury lies on the southern outskirts of the basin. An Ontario Historical Plaque was erected by the province to commemorate the discovery of the Sudbury Basin. Formation The Sudbury basin formed as a result of an impact into the Nuna supercontinent from a bolide approximately in diameter that occurred 1.849 billion years ago in the Paleoproterozoic era. Debris from the impact was scattered over an area of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Survey Of Canada
The Geological Survey of Canada (GSC; french: Commission géologique du Canada (CGC)) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations. History In September 1841, the Province of Canada legislature passed a resolution that authorized the sum of £1,500 sterling be granted to the government for the estimated expense of performing a geological survey of the province. In 1842, the Geological Survey of Canada was formed to fulfill this request.Christy Vodden (1992)No Stone Unturned: The First 150 years of the Geological Survey of Canada Geological Survey of Canada Web site William Edmond Logan was in Montreal at the time and made it known that he was interested in participating in this survey.

Pronto Mine
The Pronto Mine is an historical uranium mine located approximately 20 km south of Elliot Lake, Ontario near Spragge. The site is owned and operated by Rio Algom Ltd, has been rehabilitated and is currently undergoing environmental monitoring. The mine was in operation from 1956 to 1960, during which time it produced 4,643,835 pounds of U3O8. Upon closure of the mine, the mill was converted to a copper concentrator to process ore from the nearby Pater Mine and operated until 1970. History The Pronto mine is located on lot 3, concession II, Long township. It is located 11 miles east of Blind River, it is near the Canadian Pacific Railway and highway 17. The Pronto deposit was discovered in 1953, by geologist Franc R. Joubin, becoming the first uranium deposit discovered in the Algoma region. The prospecting was grubstaked by a J. H. Hirshhorn, a hotel owner. They formed Peach Uranium Syndicate, which later became Peach Uranium and Metals Limited and started diamond ...

Crown Corporations Of Canada
Crown corporations in Canada are government organizations with a mixture of commercial and public-policy objectives.Tupper, Allan. 2006 February 7.Crown Corporation" ''The Canadian Encyclopedia'' (last edited 2021 March 18). Retrieved 2021 May 19. They are directly and wholly owned by the Crown (i.e. the government of Canada or a province). Crown corporations represent a specific form of state-owned enterprise. Each corporation is ultimately accountable to (federal or provincial) Parliament through a relevant minister for the conduct of its affairs. They are established by an Act of Parliament and report to that body via the relevant minister in Cabinet, though they are "shielded from constant government intervention and legislative oversight" and thus "generally enjoy greater freedom from direct political control than government departments." Crown corporations are distinct from "departmental corporations" such as the Canada Revenue Agency. Crown corporations have a long-st ...

Eldorado Resources
Eldorado Resources was a Canadian mining company active between 1926 and 1988. The company was originally established by brothers Charles and Gilbert LaBine as a gold mining enterprise in 1926, but transitioned to focus on radium in the 1930s and uranium beginning in the 1940s. The company was nationalized into a Crown corporation in 1943 when the Canadian federal government purchased share control. Eldorado Resources was merged with the Saskatchewan Mining Development Corporation in 1988 and the resulting entity was privatized as Cameco Corporation. The remediation of some mining sites and low-level nuclear waste continue to be overseen by the Government of Canada through Canada Eldor Inc., a subsidiary of the Canada Development Investment Corporation. History Eldorado was originally established as Eldorado Gold Mines but, after finding radioactive deposits at Great Bear Lake, Northwest Territories in 1930, the company transitioned to primarily mining radioactive materials.

Joseph Hirshhorn
Joseph Herman Hirshhorn (August 11, 1899 – August 31, 1981) was an entrepreneur, financier, and art collector. Biography Born in Mitau, Latvia, the twelfth of thirteen children, Hirshhorn emigrated to the United States with his widowed mother at the age of six. Hirshhorn went to work as an office boy on Wall Street at age 14. Three years later, in 1916, he became a stockbroker and earned $168,000 that year. A shrewd investor, he sold off his Wall Street investments two months before the collapse of 1929, realizing $4 million in cash. Hirshhorn made his fortune in the mining and oil business. In the 1930s, he focused much of his attention on gold and uranium mining prospects in Canada, establishing an office in Toronto in 1933. In the 1950s, he and geologist Franc Joubin were primarily responsible for the "Big Z" uranium discovery in northeastern Ontario and the subsequent founding of the city of Elliot Lake.

Franc Joubin
Franc Renault Joubin, (November 15, 1911 – January 1, 1997) was an American prospector and geologist best known for a huge uranium discovery in northeastern Ontario, Canada in 1953. Born in San Francisco, California to parents of French descent, his family emigrated to Canada when he was three years old. A graduate of the University of British Columbia, ( Masters, Geology (1942)), Joubin worked independently as a consultant and prospector/geologist for various mining promoters and exploration companies. In 1953, as an employee and eventual partner of promoter Joseph Hirshhorn, he persuaded his partner to finance diamond drilling of a previously dismissed area of surface radioactivity near Blind River, Ontario. Joubin's insight, with help from Dr. Charles Davidson, a leading British geologist, was that the presence of iron sulphide had leached the uranium mineral to a location deeper in the ground. Drilling results confirmed this and implied uranium deposits along a huge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geiger Counter
A Geiger counter (also known as a Geiger–Müller counter) is an electronic instrument used for detecting and measuring ionizing radiation. It is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, nuclear industry and the Manumouthry. It detects ionizing radiation such as alpha particles, beta particles, and gamma rays using the ionization effect produced in a Geiger–Müller tube, which gives its name to the instrument. In wide and prominent use as a hand-held radiation survey instrument, it is perhaps one of the world's best-known radiation detection instruments. The original detection principle was realized in 1908 at the University of Manchester, but it was not until the development of the Geiger–Müller tube in 1928 that the Geiger counter could be produced as a practical instrument. Since then, it has been very popular due to its robust sensing element and relatively low cost. However, there are limitations in ...
