Orano is establishing a joint venture with Waseco Resources to explore the Labrador Trough project. Ce projet est vivement contesté par une partie de la population locale et par … However, in April 2013 the Quebec government announced that no permits for uranium exploration or mining would be issued in Quebec until an independent study into its environmental impact had been completed. The government has also stated that they will "ensure that all uranium deposits will remain undeveloped". In February 2010, dewatering was complete and remediation remediation proceeded. Mine de Cigar Lake; Usines. This is under Project CLEANS (Cleanup of Abandoned Northern Sites) – a multi-year project funded by the governments of Saskatchewan and Canada. The Horseshoe deposit has indicated resources of 10,400 tonnes of U3O8 at a grade of 0.20% at 100 to 400 m depth. Five of Aurora's six uranium deposits in the Central Mineral Belt fall within the Labrador Inuit lands. Uranium exploration was revived by expectations of nuclear power growth, and as a result several new uranium deposits were discovered in northern Saskatchewan’s Athabasca Basin, starting in the late 1960s. The deposit, discovered in 1981, is second in size of high-grade deposits only to the nearby McArthur River mine. McClean Lake is majority-owned (70%) and operated by Orano Canada. Fission 3.0 has the Clearwater West project adjacent to Patterson Lake South, and Canex Energy is farming into this. Orano. Areva Resources applied to increase the mill capacity to 10,900 tonnes U3O8 (9240 tU) per year, and in May 2016 CNSC licensed this. In British Columbia, the Blizzard prospect south of Kelowna, which was first explored in the 1980s, was revived by Boss Power. Registered office: Tower House, 10 Southampton Street, London, WC2E 7HA, United Kingdom. On 23 March 2020 Cameco decided to suspend production at Cigar Lake due to the threat of coronavirus. Cameco dispose de mines d'uranium au Canada, aux États-Unis et au Kazakhstan. All are metasomatite-type mineralization except for Moran Lake which is iron-ore-copper-gold (IOCG) with subeconomic uranium. A burst of exploration in the 1970s resulted in major discoveries in the Athabasca Basin in northern Saskatchewan, in Proterozoic unconformity deposits. Uranium mining is the process of extraction of uranium ore from the ground. Mine d'uranium d'Uranium City, en octobre 1975, Canada. Le pays est riche en mines d'uranium. In 2012 Cameco paid C$150 million for Orano's (then Areva Resources) 28% share. The company was spun out of Fission Energy Corp after Denison bought it in 2013, and it then took full ownership of the Patterson Lake prospects, paying Alpha Minerals C$ 185 million for its half share. Deposits around the Bancroft, Ontario, area were discovered by the early 1950s, and the first discovery in Ontario's Elliot Lake region was in 1953. The majority of Canada’s uranium resources are in high-grade deposits, some one hundred times the world average. Efforts to increase production to fill the gap left by the delay in Cigar Lake production had limited success, and development of the nearby small Caribou deposit awaits improved economic conditions. La demande en uranium commence lors du lancement, en 1942, du projet Manhattan, un programme d'armes nucléaires des forces alliées. It was North America’s longest-producing uranium mine. [3] This period marked the end of the first uranium boom and saw the number of operating mines drop to four. La production démarre en 1999. The uranium yielded C$ 330 million in export revenue, more than for any other mineral export from Canada that year. This first phase of Canadian uranium production peaked in 1959 when more than 12,000 tonnes of uranium were produced. NexGen Energy is drilling its Rook 1 property in the southwest Athabasca basin near Patterson Lake South and along strike from it, with basement-hosted mineralisation. ALX Uranium Corp is farming into Orano Canada's Close Lake Uranium Project in eastern Athabasca Basin, with the right to reach 51%. It is being drilled in a C$21million programme by Aurora Energy Resources (subsidiary of Paladin Energy, acquired in 2011). Inferred resources at both deposits added 1360 tU. Le Canada est un chef de file de l’industrie mondiale de l’uranium en pleine expansion et il a été devancé uniquement par le Kazakhstan au titre de la production totale en 2012. Exploration for uranium was restricted to Eldorado and the Geological Survey of Canada. Development of it is envisaged by about 2025. An alternative scenario with all mining underground is economically attractive but reduces production from 35,000 tU in the base case to 31,300 tU. By 1956, thousands of radioactive occurrences had been noted and by 1959, 23 mines were in operation in five districts. In 2014 a little production was reported. However, three provinces, none of which are familiar with uranium mining, have banned uranium mining and exploration: Nova Scotia (since 1981), British Columbia (1980-87 and from 2008) and Quebec (since 2013). In 1988 the newly-formed Cameco Corporation* discovered the massive McArthur River deposit. In the Otish Mountains of central Quebec Strateco Resources had been granted a licence by the CNSC to conduct underground exploration on the Matoush deposit from 2014, and commenced environmental studies for the project. À la fin des années 1950, les soviétiques exploitent une mine d'uranium à 30 km au nord-est de la ville d'Aktaou, où le surgénérateur BN-350 alimente la ville en électricité. The policy provided for exemptions in situations where Canadian partners cannot be found, and applied to uranium production only. Uranium City is one of the most unique, and beautiful, places in the province With a population anywhere from 70-200 people (depending on who you talk to), Uranium City doesn’t really qualify as a ghost town. The indigenous Inuit organization, Nunavut Tunngavic, reversed its previous ban on uranium exploration and mining in 2006, but the project has faced opposition from other groups. Orano and its partners, JCU (Canada) Exploration (33.5% in Kiggavik) and Daewoo (1.7%), hope for a start-up of the mine and mill complex when the market improves, to produce about 3000 tU/yr over 14 years.e In May 2015 the Nunavut Impact Review Board declined to approve the project due to the indefinite start date, but invited resubmission when Orano (then Areva Resources) could provide a more definite timescale. The project involves the development of three open pit mines at Kiggavik and both an open pit mine and an underground mine at Sissons, with tailings placed in a mined-out pit. In October 2014 Orano (then Areva Resources) submitted a final environmental impact statement to the Nunavut Impact Review Board. A Nunatsiavut government three-year moratorium had been in place until March 2011, affecting Michelin, and expiry of this coincided with completion of a land use planning assessment undertaken jointly by the Nunatsiavut and Newfoundland-Labrador governments. Exploration expenditure to the end of 2012 was C$ 40.5 million, and actively continues in 2015 though with no change in resource figures. [8][9], Active mine Michelin and nearby Jacques Lake are the main deposits, with minor amounts in Rainbow and three others. L'exploitation de l'uranium au Kazakhstan débute en 1943 [2] dans le cadre du projet de bombe atomique soviétique. In April 2013, UEX announced indicated resources of 30,770 t U3O8 grading 1.48% and inferred resources of 12,800 tonnes grading 1.01%, as of January, with cut-off 0.30%. A 480-metre-deep underground mine was developed in very poor ground conditions – the orebody is actually in the soft Athabasca sandstone. Orano (then Areva Resources) has protested to the federal minister responsible, saying that the process has been lengthy and thorough and the lack of firm start date should not prevent approval. Matoush has indicated resources of 5600 tU at 0.81%U and inferred resources of 6320 tU at 0.375%U, and the company projected mine production of 1000 tU/yr over seven years from 2016. In Northwest Territories, Cameco has the prospective Boomerang project in the southwest Thelon Basin. In March 2010, the Nunavut government ruled that the proposal would be reviewed by a territorial regulator rather than undergo a federal environmental assessment. Deposit/possible future minesite Remote control raise boring methods are used to mine the ore, which is then trucked 80 km south to be milled at Key Lake, site of the closed mine that once produced 15% of the world's uranium. This excludes uranium and thorium from any mineral licences in the province. Cameco is the majority owner and operator of McArthur River mine (69.8%) as well as the Key Lake Mill (Orano is a 30.2% and 16.7% partner, respectively). Hathor was subject to a takeover bid from Cameco but agreed to another from Rio Tinto, valuing the company then at C$ 654 million. Orano currently has 74.4%, Cameco 15% and JCU (Canada) 10.6%. The following table outlines some recent foreign investment in Canadian-based or established explorers, or particular projects, which have credible resources. Another UEX project is Christie Lake, 9 km northeast of MacArthur River and along strike, where some high-grade intersections have been made. Denison Mines has a 25.17% stake and OURD Canada 5.67%. In September 2013 it announced NI 43-101 indicated resources of 4900 tU grading 1.7%U for the J-Zone at Waterbury Lake. Also in Nunavut, at Amer Lake, Uranium North Resources has reported inferred resources of 9500 t U3O8. In 2016 Cameco reported on its Fox Lake deposit on its Read Lake property near McArthur River, with 30,900 t U3O8 @8% as inferred resources. After establishing a lands administration system, developing environmental protection legislation, and following a review and public consultation, in December 2011 the Nunatsiavut Assembly voted unanimously to lift a moratorium on the development of uranium deposits on Labrador Inuit lands, and this was legislated in March 2012. Mining commenced at Cigar Lake in 2014. The main uranium producers are Cameco and Orano Canada (formerly Areva Resources Canada). The estimated cost for Gunnar is C$ 280 million. This program ended in 1974 when demand for uranium for power generation was sufficient to support the industry.[3][6]. Some 115,000 tonnes of low-grade ore remains stockpiled to be treated when markets improve. Areva Resources website (www.cri.ca) [3][4][6], The ban on private prospecting was lifted in 1947. Reuse of World Nuclear Association Content, Brief History of Uranium Mining in Canada, Uranium in Canada Appendix 1: Brief History of Uranium Mining in Canada. However, in 2014 Mitsubishi showed 33.5% of Kiggavik being held by JCU, an equal three-way JV among Mitsubishi Corp, Itochu and OURD. Average operating costs are estimated at US$6.77 per pound U3O8 over the life of mine. [Back], c. Data: company sources. Il a alors assuré 15,4 % de la production mondiale d’uranium. La CCSN fournit au public et aux titulaires de permis des documents d'information comme le "Processus d'autorisation des nouvelles mines et usines de concentration d'uranium au Canada", qui aide les titulaires à mieux comprendre leur rôle et celui de la CCSN dans ce processus. In August 2018 Paladin announced that EDF Claimants held a 50% participating interest in the project, following resolution of legal proceedings. The northern Saskatchewan uranium province was also discovered in the 1950s and Eldorado Nuclear began mining at Beaverlodge in 1953. At the Key Lake mill, which has been modified for the McArthur River ore, the ore is blended with 'special waste rock' and processed to produce U3O8. Uranium in Saskatchewan series of fact sheets available on Cameco website (www.cameco.com) The strategic nature of such material resulted in a ban on prospecting and mining of all radioactive materials across Canada. Le Canada est le deuxième plus grand producteur mondial d’uranium, et sa production représente environ 15 % de la production mondiale totale. Canada • Les personnes vivant à proximité des mines et usines de concentration d'uranium au Canada ne sont pas exposées à des doses de radon supérieures à la dose de radon que reçoit le Canadien moyen 0 50 100 150 200 250 300 02468 10 12 14 16 Concentration de radon (Bq/m 3) Distance de la source (km) Référence + 2 écarts types "To suggest that uranium mining is unsafe is to imply that the CNSC and the government of Saskatchewan have been irresponsible in their approval and oversight of the uranium mines of Canada for the last 30 years." Historique de la production d'uranium au Canada. The Gryphon deposit discovered in 2014 about 3 km northwest of Phoenix was upgraded to 23,860 tU indicated resources at 1.44%U, with cut-off grade of 0.17%U. After taking over Cameco's 26.7% interest in 2018, Denison has a 90% interest and JCU (Canada) 10%. Le groupe nucléaire français proposait depuis 2009 d’ouvrir une mine d’uranium sur le site de Kiggavik, au Nunavut, le territoire autonome des Inuit dans le Grand Nord du Canada. Usine de concentration de M… Mining of Sue E deposit 2005-08 and Sue B in 2008 over 2008-10 provided ore for the mill until mid-2010 when it was shut down and put onto care and maintenance until it was upgraded to treat the Cigar Lake ore. Canada’s Non-Resident Ownership Policy (NROP) for uranium projects had, since 1987, restricted foreign ownership of uranium mines to a maximum of 49%. The head of CNSC then wrote to Quebec’s minister questioning the report’s recommendations, saying that they lacked “scientific basis and rigour” and hence were misleading for all Canadians. La Namibie, avec 463 000 tonnes de réserves d’uranium, arrive en quatrième position dans la liste des pays ayant les plus grandes réserves d’uranium. In 1944, the federal government took over the Eldorado company and formed a new Crown corporation which later became Eldorado Nuclear Ltd. Many of these have difficult mining conditions which require ground freezing. Data: company sources. ALX Uranium holds a 20% share. On 23 March 2020 Orano Canada decided to suspend production at the McClean Lake mill in response to the coronavirus pandemic. The mill is also expected to treat other ores in due course, notably from Midwest. After starting operation in mid-1999, McClean Lake produced about 2500 t/yr of U3O8 from 2.4% ore up until 2005, although production was well down in 2006 through to 2010 due to lower ore grades. [4] In 2008, the government established a "no registration reserve" under the Mineral Tenure Act for uranium and thorium. In December 2018 Denison announced that it would proceed with developing an ISL operation at Phoenix with a view to production in 2024. Uranium was discovered at Rabbit Lake in 1968 and it was brought into production by Cameco in 1975. Cameco was continuing its underground drilling reserve replacement program in areas of interest north and northeast of the current mine workings. The revised arrangement reduced costs by 20%. Initial treatment of the ore is at Cigar Lake, with average slurry grade of about 15% U3O8 for shipment to McClean Lake. This ban appears to be temporary. However, underground floods in 2006 and 2008 set the start date back until 2014 and increased the overall cost of the project from C$660 million to about C$2.6 billion. Ce processus de concentration produit une poudre d'uranium naturel appelée yellowcake. Uranium exploration was not subject to NROP, and there were several exploration-level uranium assets in Canada with major foreign ownership which cannot proceed to mining unless the NROP was liberalised. The first ore slurry was sent to the McClean Lake mill in March 2014, and treatment began there in October 2014. In December 2015 China’s CGN Mining Company Ltd agreed to buy 20% of Fission for C$82 million. La production d’énergie étant en hausse dans le pays, l’Afrique du Sud possède deux réacteurs nucléaires qui produisent 5 … La mine d'uranium géante de Cigar Lake, située dans la province de la Saskatchewan, au Canada, a effectué ses premières livraisons de minerai. Reserves are small. The decision was made in conjunction with Orano's McClean Lake uranium mill. Orano reports that its and Cameco's Waterbury Cigar Lake project aims to discover an extension of the nearby Cigar Lake orebody. In April 2019 probable reserves were 31,650 tU at 1.37%U accessible by open pit (NI 43-101 complaint). A 626-page report by Québec's Bureau d'audiences publiques sur l'environnement (BAPE) was published by the province's minister for sustainable development, environment and climate change in July 2015. Au Québec, aucune mine d’uranium n’est en production; nous en sommes toujours au stade de l’exploration. Uracan Resources reports 3100 tonnes U3O8 of indicated resources and 16,900 tonnes of inferred resources in the Double S zone at its North Shore prospect in eastern Quebec. A preliminary economic assessment for Hathor had suggested low production costs over an 11-year mine life producing 1900 tU per year. The 425 m level was backfilled and new workings developed in more competent rock at 480 m level. Denison's Wheeler River project is halfway between Key Lake and McArthur River and immediately east of Millennium. In Canadian figures resources do not include reserves and are reported in accordance with Canadian standard NI-43-101. [1] Currently the only producing area in Canada is northern Saskatchewan, although other areas have had active mines in the past. Orano says that the mill is the most technologically-advanced in the world, being able to treat ore from less than 1% to 30% U, and is the only facility capable of processing high-grade uranium ore without diluting it. From Wikipedia, the free encyclopedia The Cigar Lake Mine is a large high grade underground uranium mine, located in the uranium rich Athabasca Basin of northern Saskatchewan, Canada. The Midwest A deposit, 2km to the north, had 4900 t U3O8 indicated at 0.87%. A moratorium on uranium exploration was declared in the province of Nova Scotia in 1984. La mine de McArthur River y a des teneurs de 19 à 25 %. Mineur mesurant la radioactivité dans la mine d'uranium d'Uranium City, en octobre 1975, Canada. The Saskatchewan Research Council (SRC) is undertaking remediation of several mine and mill sites in northern Saskatchewan including Gunnar mine (operated 1955-64) and Lorado mill as well as 35 satellite mine sites near Lake Athabasca. [2] 14.5% of the world production came from one mine, McArthur River. La mine appartient aux sociétés Areva (70%), Denison Mines (22.5%) et Ourd Canada (7.5%) [1]. "It should be recalled that on the basis of extremely detailed, rigorous environmental and social impact studies, Strateco received approvals for the underground exploration phase of the Matoush project from the Canadian Nuclear Safety Commission, the federal Minister of the Environment and the federal administrator of the James Bay and Northern Quebec Agreement, as well as a positive recommendation from the provincial evaluation committee," the company said. In December 2014 Strateco launched a C$ 183 million claim against the provincial government in the Superior Court of Quebec for the loss of its investments. La production d’uranium au Canada est passée de 9 000 tonnes environ par année au début des années 1990 à 12 920 tonnes par année en 1998. Depuis 2008, aucune extraction classique n'a été réalisée à McClean Lake. [3][4][6] In 1959, Canadian uranium exports were valued at $330 million, more than for any other mineral exported from Canada that year. "It is clear that the BAPE's recommendations not to proceed is based on the perceived lack of social acceptance and not on proven science.". This includes 12,730 tonnes in Lac Cinquante deposit and 6,950 tonnes in J4/Ray, with good intersections in Dipole, 25 km southwest of it, still unquantified. L'aménagement du site a débuté en 1994. UEX is also exploring the Horseshoe and Raven deposits at Hidden Bay in the eastern Athabasca basin (5 km from Rabbit Lake and 12 km from McClean Lake). It also has enormous reserves of high grade ore (16.5% U3O8 after allowance for dilution) located 600 metres underground. In June 2015 the Canadian government approved Paladin’s ownership of the project, exempting it from the Non-Resident Ownership Policy (NROP) applying generally, allowing it to proceed to production. In 2009 Kazakhstan took over top spot, relegating Canada to second. Une fois le minerai extrait de la mine, on le broie généralement pour obtenir des particules de taille uniforme, après quoi un procédé de lixiviation chimique permet d'en retirer l'uranium. In Canada, uranium ores first came to public attention in the early 1930s when the Eldorado Gold Mining Company began operations at Port Radium, Northwest Territories, to recover radium. Hence it uses ground freezing and remotely-controlled high pressure water jets at this level to excavate the ore. Production ramped up to 8,200 t/yr U3O8 (7,000 tU/yr) in 2017 and remained at that level in 2018 and 2019. Cameco dispose de mines d'uranium au Canada, aux États-Unis et au Kazakhstan. A refinery to produce radium was built the following year at Port Hope, Ontario, some 5000 km away. Following the April 2013 moratorium, in November 2013 the Quebec government refused to authorize the Matoush underground exploration phase. Cameco produit et commercialise également les réacteurs nécessaires à la transformation de l'uranium en électricité [2]. The suspension, due to persistent uranium price weakness, was expected to last for 10 months, but in July 2018, Cameco announced that the mine was shut for an "indeterminate period". Orano Canada et Cameco Corporationsont les titulaires de permis pour les installations d'extraction et de concentration d'uranium en exploitation. Canadian Nuclear Association website (www.cna.ca) In March 2018 Denison announced that indicated resources were 23,000 tonnes of U3O8 at 2.3%, 18,100 tonnes of this in the Main deposit at 4.0% grade. Uranium exploration was restricted to the joint efforts of Eldorado and the Geological Survey of Canada. Mines d'uranium. A prefeasibility study reported in April 2019 envisaged a hybrid open-pit and undergound operation producing an average 5700 tU per year over the first five years. Cluff Lake, Key Lake and the original open pit at Rabbit Lake have now been mined out (underground mining continued at Rabbit Lake to 2016). La production d'énergie nucléaire représentait 15% de l' électricité du Canada en 2017. The mine was relicensed at 3640 t/yr. Les derniers employés réguliers de la mine d'uranium de McArthur River et de l'usine de concentration d'uranium de Key Lake, dans le nord de la Saskatchewan, quitteront les deux mines … Today, the provincial government actively supports uranium mining, and all new Saskatchewan uranium mines have international ISO 14001 environmental certification. Uranium mines and mills waste section of Canadian Nuclear Safety Commission website (www.nuclearsafety.gc.ca) The McClean Lake mill has been upgraded and expanded to 8,200 tonnes U3O8 (7000 tU) per year to accommodate all the ore from the Cigar Lake mine (see section on Cigar Lake below). * Not included in latest company reports. However, this period marked the end of cost-plus production for export, and over the next few years the number of mines declined to four. [1] 20% of the world's primary uranium production came from mines in Canada in 2009. The East Zone is a series of moderately-dipping stacked, parallel lenses (greater than 0.5% U3O8). It is basement-hosted in igneous rock starting 100 m deep and extending down for 800 m. A preliminary economic assessment in mid-2017 put the capital cost of the mine, plant and infrastructure at C$1.66 billion, for average annual production of 7130 tU, but with very low operating cost. In November 2014 Toro Energy from Australia acquired a 19.8% interest in Strateco as part of a financing package. In addition to mining operations planned for the near future, active exploration involving more than 40 companies continues in many parts of Canada. The ore will be shipped 15 km to the McClean Lake mill. La Commission canadienne de sûreté nucléaire (CCSN) réglemente et autorise toutes les activités actuelles et futures d'extraction et de concentration d'uranium ainsi que toutes les installations de traitement d'uranium et de fabrication de combustible au Canada. Denison Mines (22.5%) and the Japanese company Overseas Uranium Resources Development (OURD Canada, 7.5%) are Orano's joint venture partners. In the Kivalliq region of Nunavut Territory, some 500 km north of Manitoba, a joint venture headed by Orano has been conducting a feasibility study on the Kiggavik uranium deposit in the Thelon Basin, with 48,950 tU indicated resources at 0.47%U grade.
