JEB Tailings Management Facility Expansion Project at McClean Lake

Federal environmental assessment cancelled for JEB Tailings Management Facility Expansion Project at McClean Lake, as a result of change in legislation

On July 6, 2012, the new Canadian Environmental Assessment Act, 2012 came into effect, changing the requirements for "low-risk" environmental assessments (EAs). As a result, the EAs underway on these projects are no longer required under the former CEA Act, and the assessment of the proposed expansion of Areva Resources' McClean Lake uranium tailings facility was cancelled.

CNSC starts Environmental Assessment on JEB Tailings Management Facility Expansion Project

The Canadian Nuclear Safety Commission (CNSC) has received a project description from AREVA Resources Canada's (AREVA) for a licence amendment to expand the JEB Tailings Management Facility (TMF) at the McClean Lake Operation.
AREVA is proposing to expand the existing JEB TMF to increase the storage volume for tailings generated from milling activities. The project includes the construction of an embankment around the JEB TMF perimeter and placement of a processed waste rock/till bentonite amended liner to contain the pond. The proposed expansion would increase the elevation of the stored tailings from 434 metres above sea level (m ASL) to 465.5 m ASL. Further, the expansion would add approximately 4.5 million cubic meter of additional tailings capacity. It is estimated that this increased tailings management capacity will expand the useable life span of the existing JEB TMF by 25 years, based on current mining predictions.

Areva considers trucking ore from McArthur River mine to keep McClean Lake mill operating

Areva Resources Canada Inc. is considering trucking ore 920 kilometres from the McArthur River uranium mine to be processed at its McClean Lake mill. The plan, which has not yet reached the proposal stage, would keep operations at Areva's 70 per cent owned McClean Lake facility going while it waits for ore from Cameco Corp.'s Cigar Lake deposit, said Areva spokesperson Alun Richards. Ore from McArthur River, which is 30.2 per cent owned by Areva, is milled at the nearby Key Lake facility.
Uranium mining at the McClean Lake operation ended in January, leaving the specialized facility without a nearby ore resource. The mill is set to process ore from Cigar Lake, in which it has a 31.7 per cent share -- a plan that has been delayed after flooding at the mine pushed operations back by several years.
At the moment, the plan is to ship about three million pounds of uranium ore slurry in special trucks and containers from McArthur to McClean until Cigar Lake comes on stream. According to Cameco, 13.1 million pounds of U3O8 [5038 t U] is set to be mined from McArthur River and Key Lake in 2009. (The StarPhoenix Aug. 14, 2009)

 

McClean Lake mill to be shut down in mid-2010

Areva Resources Canada Inc. announced plans Tuesday (Dec. 15) to shut down production at its McClean Lake uranium mill in northern Saskatchewan in July 2010. A company spokesperson said Tuesday afternoon yellowcake production at the McClean Lake operation is being ceased because the mill will run out of ore to process by July.
The mill, which has been in operation since 1999, was designed to handle high-grade ore from the nearby Cameco Corp.-operated Cigar Lake project. Cigar Lake, which is 37 per cent-owned by Areva, was set to enter production earlier this decade, but was set back by flooding in 2006 and 2008. Although the dewatering process is continuing at the site, which is the world's largest undeveloped high-grade uranium deposit, there is no indication of when production will begin at Cigar Lake. Additionally, mining operations at the McClean Lake mine all but ended in January. Work on the nearby, joint-ventured Areva/Denison Mines Inc. Midwest and Caribou deposits, meanwhile, remains postponed due to market conditions. Areva says the mill re-start date will depend on market conditions and the Cigar Lake mine schedule.

Athabasca Regional Government challenges license renewal for McClean Lake mine and mill

The Athabasca Regional Government (ARG), which is comprised of three First Nations and four provincial communities from the Athabasca Basin, launched a judicial review of CNSC's decision to grant the McClean Lake operating licence. The ARG are challenging the legality of the new licence, primarily on the basis of issues related to the Federal and Provincial governments' duty to consult with Aboriginal people. (Denison Mines Corp. Aug. 12, 2009)

On September 22, 2010, the Federal Court of Canada external link released its decision in the matter of an application by the Athabasca Regional Government (ARG) for judicial review of the decision by the Canadian Nuclear Safety Commission to renew AREVA's McClean Lake uranium mine and mill operating licence. The Honourable Mr. Justice Russell dismissed the application. The ARG had raised a number of issues relating to the insufficiency of Aboriginal consultation and the legal authority of the Commission to fulfill the duty to consult on behalf of the federal government.
The Court determined that the Commission had the authority in accordance with its legislation to deal with Aboriginal consultation on behalf of the Crown and that such issues properly fell within the Commission's statutory mandate and expertise in accordance with section 35 of the Constitution Act (1982).

McClean Lake mill faces temporary shutdown until Cigar Lake mine operable

Areva Resources Canada Inc. is on the hunt for new sources of uranium ore to be milled at its McClean Lake facility after mining operations at the site all but ended in January.
Ore from the Cigar Lake mine -- in which Areva has a 37 per cent share -- is set to travel to McClean Lake by road; however, there is no set date for when that ore will become available. In August 2008, water inundated the Cigar Lake mine while work was being done to dewater the site after a flood in 2006. Flooding at the site pushed back production at the mine which, before the 2006 flood, was expected to come into production in 2007. After the incident last summer, Cameco officials said production may come onstream in 2011 at the earliest. (The StarPhoenix June 18, 2009)

Lower production estimates announced for McClean Lake mine

On May 16, 2007, Denison Mines Corp. announced that AREVA Resources Canada Inc., the operator of the McClean Lake Joint Venture has provided an updated estimate of 2007 production of 1.8 million pounds of U3O8 [692 t U], a reduction from the previously reported level of 2.2 million to 3 million pounds [846 - 1154 t U]. According to Denison, the reduction in estimated 2007 production is a result of delays in obtaining regulatory approval and implementing planned mill modifications to increase leaching capacity, later than expected completion of revisions to the tailings distribution system and the suspension of further jet boring drilling at the McClean North deposit.

 

Serious production setback at McClean Lake mine

"The McClean Lake Joint Venture produced 455,000 pounds of uranium [175 t U] during the three months ended September 30, 2006 compared with 1,532,000 pounds [589 t U] during the same period in 2005. [...] Production for the first nine months of the year has been well below our expectations due to lower grade ore feed, the absence of higher grade ore from the blind boring/jet boring operations, reduced throughput caused by variances in the arsenic concentration of the ore feed that resulted in elevated temperatures in the leach circuit and a shortage of reagents due to road closures caused by forest fires. [...] Average mill feed grade for the third quarter 2006 was 0.58% U3O8 compared to 1.73% U3O8 for the comparable 2005 period." (Denison Nov. 9, 2006)

 

Ferric Sulphate Production Project at McClean Lake

Following a hearing on October 25, 2006, in Ottawa, Ontario, the Canadian Nuclear Safety Commission (CNSC) announced its conclusion that AREVA's proposed project to install and operate a ferric sulphate production circuit at the McClean Lake Operation located in Northern Saskatchewan, taking into account identified mitigation measures, is not likely to cause significant adverse environmental effects. The project involves the production of liquid ferric sulphate from iron ore transported to the McClean Lake site.

COGEMA Resources Inc. has proposed to produce liquid ferric sulphate (Fe2(SO4)3) at McClean Lake from iron ore imported to site, which would replace the current practice of purchasing ferric sulphate commercially and transporting it to the mine site. Ferric sulphate is used in the mill to remove dissolved arsenic in the tailings' pore water prior to discharge to the Tailings Management Facility, and in the treatment of effluent prior to discharge from water treatment plants. Before CNSC makes its decision on the proposal, an environmental assessment (EA) must be completed. The EA was started on Feb. 8, 2006.
CNSC held a closed (!) hearing on March 30, 2006.
On June 2, 2006, CNSC approved the guidelines for an environmental assessment.

Expansion of the JEB Mill at McClean Lake to receive and process Cigar Lake ore

McClean Lake mill produces first uranium concentrate from ore mined at Cigar Lake mine

On Oct. 8, 2014, Cameco announced that the McClean Lake mill has started producing uranium concentrate from ore mined at the Cigar Lake operation in northern Saskatchewan.
The McClean Lake mill, operated by AREVA Resources Canada Inc., recently completed modifications required to safely process the [undiluted] high-grade ore from the Cigar Lake mine. Cigar Lake ore is transported by truck to the McClean Lake mill located 70 kilometres northeast of the minesite for processing. The mill is expected to produce up to 1 million pounds of uranium concentrate [385 t U] from Cigar Lake ore in 2014 and ramp up to its full production rate of 18 million pounds [6,923 t U] by 2018.

Processing of Cigar Lake ore at McClean Lake mill to start with delay

AREVA has advised Cameco that it has determined that further mill modifications are required and that the mill is expected to begin processing Cigar Lake ore by the end of the second quarter of 2014. (Cameco Sep. 9, 2013)

McClean Lake mill obtains license for processing of Cigar Lake ore

On January 9, 2013, Areva Resources Canada Inc. announced it has received a licence amendment for its McClean Lake operation in northern Saskatchewan from the Canadian Nuclear Safety Commission's (CNSC) allowing for processing of high-grade ore from the Cigar Lake mine, expected to begin operations later this year. This CNSC decision announced on Dec. 20, 2012, allows AREVA to operate the receiving and milling circuits for high-grade ore and increase the annual capacity of the McClean Lake mill to 13 million pounds (5,900 tonnes) of uranium concentrate. It also allows AREVA to receive and process ore from the McArthur River mine should it decide to pursue this contingency.

Areva begins expansion of McClean Lake uranium mill for processing of Cigar Lake ore

French nuclear giant Areva says it has started the first phase of construction to expand its McClean Lake uranium mill in northern Saskatchewan.
Areva and its partners are investing C$150 million to upgrade the mill and increase its capacity. The upgrade is being done so that the mill can process uranium ore from the Cigar Lake mine slated to begin production late next year. The work includes construction of a storage facility for yellowcake, the powder that is an intermediate step in the processing of uranium ores.
Areva says in a news release that primary construction at McClean Lake, which includes expansion of solvent extraction and acid plants, is to begin next June. (The Canadian Press July 5, 2012)

New uranium mineralization found at McClean Lake

New unconformity related uranium mineralization was discovered in the Athabasca sandstone. Approximately 20 diamond drill holes have tested structural and geological targets in the Caribou Lake area, approximately two kilometres northwest of the Sue C open pit. (Denison release April 12, 2002)

 

McClean Lake mining suspended after Sue C mining completed

"COGEMA Resources will suspend mining at its McClean Lake operation after completion of the Sue C mine.
Vincent Martin, senior vice-president and chief operating officer, says that by the end of 2001, the company will have enough ore stockpiled to feed the mill for four to five years. [...]
And while the mining at McClean Lake is expected to be complete within the next few years, the mill is expected to continue to run another 40 years with ore from the Cigar and Midwest projects." (COGEMA Res. Communiqué Dec. 2001)

Mining of the Sue C pit was completed on February 3, 2002 with all of the ore stockpiled for feeding the mill into 2006. (Denison, March 6, 2002)
