SMDC is a commercial corporation owned by the Government of Saskatchewan, Ucanerz a wholly- owned subsidiary of Uranerzbergbau Cmbh. of Germany and Eldor, a wholly-owned subsidiary of Eldorado Nuclear Limited, a commercial corporation owned by the Government of Canada. The history of the ownership of the project is quite complex. Its early beginnings go back to 1968 when Uranerz Exploration and Mining Limited, joined with Inexco Mining Ltd. and seven other companies to form a joint venture to explore the Athabasca sandstone region of northern Saskatchewan. By 1970, when the market price of uranium was about $6 a pound, six companies dropped out, leaving Uranerz, Bell oil and Inexco. all with equal shares. By 1974, discouraging results led Bell Oil Co. to decide to leave the joint venture. The other t;-;o partners (Uranerz and Inexco) offered Bell's one-third share to the Saskatchewan government who established SMDC to act as its agent. In 1978, Inexco decided to sell its 1/3 share to SMDC which sold one-half of this share to Eldor Resources Limited. Thus the partnership came to be the present arrangement of SMDC: one-half; Uranerz: one-third; Eldor; one-sixth. OPERATOR: Key Lake Mining Corporation (KLMC). wholly owned by the joint venture partners, is the operator of the project. OREBODY STATISTICS: The three sources of ore at Key Lake contain 70,100 tonnes U or 182,400,000 pounds U,0o, J o consisting of the following: CO o o o O O o o o o 2a m o o o o D o o o o W o o o o rH in CO E CJ D a 8 o O o o CO o o o o r~ c C CM 0 (Nl EH o n m w Q CTl IN o o o o o o o o o o o o 01 13 o o o o C o o o o u o o o o Po o r~ in (N en us o r* PI r- 1 r-l 'S r-H o O o o in o o o o 0) o o o o c hi c 'J* r- r~ CO o H H CO rH EH CO rH m in O W 8 EH PROJECT OVERVIEW The Key Lake uranium deposits in northern Saskatchewan are high in grade and near the surface. The first deposit was discovered in 1975. Uranerz Exploration and Mining Limited, the operator in a joint venture exploration project, struck high-grade uranium ore in a diamond drill hole near Key Lake. Subsequent drilling outlined the Gaertner orebody. Continued diamond drilling in the Key Lake region resulted in the discovery, about one year later, of a second discrete high-grade uranium deposit, the Deilmann orebody. Development of the project proceeded to the stage where an Environmental Impact Statement was prepared and filed with the Saskatchewan Department of the Environment in late 1979. The Key Lake Boad of Inquiry was commissioned in December, 1979 and completed public hearings on the site-specific environmental and socio-economic aspects of the project by the end of 1980. In February, 1981 the Board recommended that the project proceed, subject to conditions which would protect employees and the environment and increase the benefits to residents of northern Saskatchewan. The provincial government accepted the Board's report and subsequently signed a surface lease agreement with KLMC on August 27, 1981 covering a 21-year period. For a brief historical background see Appendix 1. On site construction began immediately under the supervision of the engineering, procurement, construction and management consultant. Wright Commonwealth Joint Venture. For a more detailed summary see Appendix 2. Ore is extracted by open pit mining methods with separate pit development for each deposit. The mill is designed to process 700 tonnes (780 tons) of ore per day and employs conventional separation and extraction techniques to process the high-grade ore. Overall uranium recovery will be greater than 97% and annual production capacity will be 5.440 tonnes U O (12 million pounds U O ). 3 8 3 8 Although the maximum output capacity is among the largest by world standards, the design of the mill and the high grade of the ore permit efficient production at lower levels. This provides flexibility for the operator to respond to market conditions and customer requirements. For comparison to other uranium mines see Appendix 3. Access to Key Lake is by air and road. A gravel airstrip has been constructed and an all-weather road to the mine site has been completed. THE WORK FORCE The Key Lake project employs 450 people. Following a study of employee turnover at similarly remote mines and taking into consideration the social fabric of the native people working at the project, it was decided not to establish a townsite at Key Lake. Instead, a 7-day in, 7-day out commuter system is in effect. Under this system, employees are flown from six northern designated pickup points (La Ronge, Pinehouse, lie a la Crosse, Buffalo Narrows, Cumberland House and Pelican Narrows) to the mine, where they work an 11-hour shift each day for seven days. They then return home for a seven-day period, while their replacements are working at the project site. Thus at any one time only half the work force is on site. This work schedule has proven successful in other uranium operations in northern Saskatchewan. It avoids social problems that. frequently arise in small, remote development-based communities. Since northerners comprise a substantial part of the Key Lake work force, this schedule should be less disruptive to their community lifestyle. For those who are accustomed to making their living by trapping and fishing, the routine of being away from home several days at a time is not new. MINING KARL ERNST LAKE COBBLE ORE BASEMENT ROCK GRAPHITE GNEISS »SANDSTONO A MHOT E PIT FLOOR / p i ca 1 — Cross Section ofGacriner Deposit (Looking Northeast) Overburden The Gaertner pit is estimated to contain approximately 7.7 million cubic metres of overburden material (sand and till), varying in depth from 20 to 60 metres. Scrapers first, then shovels and trucks began removing overburdern from an area approximately one-third the ultimate surface area of the pit. The material has been transported to the waste storage area. Removal of overburden covering the Deilmann orebody will begin at a suitable time to provide continuity of flow of ore to the mill. The overburden from the Deilmann area is estimated to amount to 21 million cubic metres, almost three times the volume covering the Gaertner orebody. Removal of this material will generally follow the procedures used in developing the Gaertner pit. Grour.-awat.er The terrain in the Key Lake area, composed largely of glacial sand and till, results in ground water levels that are close to the land surface. Precipitation tends to seep into this glacial material, in part because of the porous nature of sand and in part because of the scarcity of vegetative ground cover owing to poor soil conditions. Therefore, it was necessary to lower the ground water level while the overburdern is being removed and throughout the period of mining, keeping the ground water level below the bottom of the pit. KLMC sank a series of wells around the perimeter of the Gaertner pit so that ground water could be pumped from the production areas into the natural water drainage system leading to the Wheeler River. The mining of ore at Key Lake began in May, 1983 and will continue until at least the year 2000. Standard open pit mining techniques are employed. Rock containing the ore is broken using a 8 bulldozer and, when required, by conventional drilling and blasting. The ore is loaded onto trucks and transported to the primary crusher, which reduces it to a small, fairly uniform size. The crushed ore is transported to the stockpile area, where it is blended in order to achieve a uniformly graded material for metallurical processing. Most mining activities will be worked two shifts a day. seven days a week. 12 months a year. The ore zone, however, will probably be worked one shift a day, seven days a week. 10-12 months a year. Once the Key Lake orebodies have been mined out, natural ground water levels will be restored in the area. The dump areas used to store the overburden will have an average height of approximately 20 metres above general topography, similar to the existing undulating terrain in the immediate vicinity.

  • Reasons for Decision Ministerial Approval Ministerial Change Approval Pursuant to Section 16(2)(C) the Environmental Assessment Act
    REASONS FOR DECISION MINISTERIAL APPROVAL MINISTERIAL CHANGE APPROVAL PURSUANT TO SECTION 16(2)(C) THE ENVIRONMENTAL ASSESSMENT ACT CAMECO CORPORATION KEY LAKE EXTENSION PROJECT Introduction The Environmental Assessment Act (hereinafter called the Act) states that where a proponent has received Ministerial Approval to proceed with a development and the proponent intends to make a change in the development that does not conform to the terms or conditions contained in the approval, the proponent must receive Ministerial Approval prior to making those changes. On February 13, 1981 Ministerial Approval was issued to Key Lake Mining Corporation for the Key Lake Mine and Mill Project (EAB#: 1976-006). Several changes to the Key Lake operation have also received Ministerial Approval pursuant to Section 16(2) of the Act (EAB# 1990-048, 1991-031, 1992-001, 1998-015, 2000-025, 2002-055, 2003-005). These changes have related to tailings deposition location and methodology, development of the mined-out Deilmann pit as the Deilmann Tailings Management Facility (DTMF), processing of ore from the McArthur River mine, processing of by-products generated at facilities in Ontario and increasing milling and processing rates at the facility. In March 2010, Cameco submitted a proposal for a change to the previously approved Key Lake operation to allow increased tailing storage in the existing DTMF, an increase of the Key Lake mill nominal annual production capacity, an increase to the ore storage area and modifications to the existing mill (the project). The proposal was sent to provincial agencies and the Government of Canada for technical review. Following technical review, it was determined that the proposed change did not conform to the terms and conditions of previous approvals and therefore Cameco would require approval under section 16(2) of the Act prior to proceeding and would be required to conduct an environmental impact assessment (EIA) for the proposed change.

  • History of Mining in Saskatchewan
    History of Mining In Saskatchewan Early Mining in Saskatchewan The earliest mining occurred when earth’s inhabitants started using various stones for tools or certain clays for cooking vessels. The earliest recorded occupation in Saskatchewan was around 9000 B.C. at the Niska site in the southern part of the province. Ample evidence of the use of stone tools, arrow heads, and spear heads, etc. has been found in the area. Much of the material used by these early inhabitants was imported or traded from other regions of North America. The study of the stone tools provides us with information about the people’s work, their history, their religion, their travels and their relationships with other groups or nations. Stone is readily available throughout most of Saskatchewan. This was especially important for Saskatchewan’s First Nations people who moved their camps frequently in search for food. The stones available were not all suitable for tools and they needed a constant supply of stone material that broke cleanly or was hard enough for pounding. Consequently, they made regular trips to the source areas or traded with people who lived near the sources. For these early residents of our province, the exchange of goods was more than just a means of acquiring things. Bartering and gift exchange was a means of creating and reinforcing relationships between individuals, families and nations. For thousands of years, goods have been exchanged through networks that extended across North America. Although perishable goods were also traded, our records are in the form of shell or stone artefacts.

  • TITLE: Cameco Corporation: Uranium Mining and Aboriginal Development in Saskatchewan[1]
    This case was written by Saleem H. Ali for the purpose of entering the 2000 Aboriginal Management Case Writing Competition. TITLE: Cameco Corporation: Uranium Mining and Aboriginal Development in Saskatchewan[1] The Setting The topic of Bernard Michel's speech was general in nature, yet quite specific in substance: "Corporate Citizenship and the Saskatchewan Uranium Industry." He had been invited by the Uranium Institute in London, UK to share his company's experiences in negotiating agreements with Native communities in Northern Saskatchewan. As the President and Chief Executive Officer of Cameco, the world's largest uranium mining company, his speech was much anticipated by the audience. The Uranium mines of Saskatchewan are an interesting laboratory for the study of corporate community relations......The community relations programme's first action was to listen through public hearings to the communities' expressed concerns.......Today 80% of Saskatchewan's residents, compared with 65% in 1990, support continued uranium mining. This reflects the industry's community relations initiative. Cameco's shares also trade at 3.5 times their 1991 issue price. Only a small segment of anti-nuclear activists takes a negative view. Relationships with local communities, like uranium ore, are a valuable resource needing competent development.[2] Originally from France, and a graduate of the Ecole Polytechnique in Paris, Michel, had spent the past two decades in Canada working for various mining interests. Having served as Senior Vice President, Executive Vice President and President for a subsidiary of the French nuclear conglomerate Cogema, Amok Ltd, Michel had eminent credentials to join Cameco in 1988.

  • Advances in Geophysical Exploration for Uranium Deposits in the Athabasca Basin
    Ore Deposits and Exploration Technology _______________________________________________________________________________________ Paper 52 Advances in Geophysical Exploration for Uranium Deposits in the Athabasca Basin Powell, B. [1], Wood, G. [1], Bzdel, L. [1] _________________________ 1. Cameco Corporation, Saskatoon, Canada ABSTRACT Some recent Greenfield discoveries made by Cameco in the last 10 years include the Millennium Zone on the Cree Extension project, and La Rocque Lake and Collins Creek on the Dawn Lake project (eastern Athabasca), and the Centennial Zone on the Virgin River project (central Athabasca). These illustrate some of Cameco’s advances in geophysical exploration methods over this period of time. The Millennium zone (2000) is a basement-hosted discovery that demonstrates the value of drilling away from the historic conductor axis. Considerable difficulty had been experienced drill intersecting the hanging wall B1 conductor, as defined by Fixed Loop Time Domain Electro-Magnetic (TDEM) coverage in the general area of the Millennium zone. Significant alteration was noted in drill core from deep within the basement of a single drill hole step-out (CX-38) to the west of the Fixed Loop B1 conductor tested by CX-35. A second step-out, CX-40, led to the discovery of the Millennium zone. Subsequently, Stepwise Moving Loop TDEM profiles were completed to map a previously unidentified footwall conductor closely associated with the ore zone and therefore important for furthering the delineation drilling. TDEM Soundings, Pole-pole DC Resistivity and TAMT surveys mapped significant alteration anomalies in the sandstone above the mineralization, which are inferred to be related to the mineralizing process. The La Rocque Lake (1998) and Collins Creek (1999) discoveries are classical unconformity uranium zones that demonstrate the use of combined Fixed Loop and Stepwise Moving Loop TDEM surveys for definition of complex multi-conductor systems.
