  • Thickened Tailings Disposal at Musselwhite Mine
    Paste 2011 — R.J. Jewell and A.B. Fourie (eds) © 2011 Australian Centre for Geomechanics, Perth, ISBN 978-0-9806154-3-2 doi:10.36487/ACG_rep/1104_21_Kam Thickened tailings disposal at Musselwhite Mine S. Kam Golder Associates Ltd., Canada J. Girard Goldcorp Canada, Canada N. Hmidi Goldcorp Canada, Canada Y. Mao Golder Associates Ltd., Canada S. Longo Golder Paste Technology Ltd., Canada Abstract Musselwhite Mine in Northwestern Ontario, Canada began thickened tailings disposal in May 2010. Surface disposal of thickened tailings for the 4,000 tpd gold mine was chosen following a series of studies beginning in 2002 to investigate options to expand the capacity of the tailings management area. This technology was considered most cost effective in maximising storage capacity within the existing site footprint. The elimination of a pond for closure will reduce the risk of dam failure. Further, the non-segregating tailings are expected to be relatively impervious and saturated. These characteristics will help inhibit tailings oxidation and reduce the likelihood of acid generating and metals leaching in the long term. Musselwhite Mine is currently planning to remove the sulphide minerals from the tailings stream using a flotation plant. This paper discusses the design of the thickened tailings disposal system and presents preliminary observations on tailings deposition to date. In preparation for thickened tailings disposal the tailings management area was partitioned by an internal dyke in 2008. This has allowed tailings to be ‘stacked’ using the upstream method of construction in the west cell and the east cell to serve as a water management pond. The cold climate presents a special challenge to operating the thickened tailings system as there is very little precedent experience.

  • Musselwhite Mine
    PARTNERSHIP AGREEMENTS The Minerals and Metals Sector of Natural Resources Canada promotes the participation of Indigenous communities in minerals and metals activities across Canada by sharing information on Indigenous industry leading practices. Musselwhite Mine The Project The Musselwhite gold mine in northwestern Ontario is a fly-in, fly-out operation on the southern shore of Opapimiskan Lake, about 480 kilometres (km) north of Thunder Bay in North West Ontario. An all-weather road connects the mine to the community of Pickle Lake, about 200 km to the south. The Musselwhite property is 17,548 hectares, entirely on First Nations land. Since its first commercial production in April 1997, the mine has produced more than 4 million ounces of gold. Signed Agreements Musselwhite was one of the first mines in Ontario to enter into a comprehensive agreement with local First Nations communities, called the Musselwhite Agreement. In September 2001, the Musselwhite mine, the First Nation communities of North Caribou Lake, Cat Lake, Kingfisher Lake and Wunnumin Lake, the Shibogama First Nations Council, and the Windigo First Nations Council renewed the The agreement also establishes an Environmental Musselwhite Agreement originally signed in Working Committee and a Musselwhite Working 1996. The agreement sets targets for First Nations Committee to monitor socio-economic matters. Each employment, opportunities for business development committee includes community representatives, and and environmental protection. Under a separate the chiefs and mine management meet regularly to agreement, local trappers are compensated for the monitor implementation of the agreement and resolve loss of harvesting rights within a designated area disputes. In 2014, through the agreement, signatory around the mine.

Musselwhite Mine Post Office Box, No. 7500 Thunder Bay, Ontario P7B 6S8 Site Location: Musselwhite Mine - Patricia Mining District Unsurveyed Territory (Kenora Area Office) Unorganized Area, District of Kenora You have applied in accordance with Section 53 of the Ontario Water Resources Act for approval of: establishment of sewage works for the collection, transmission, treatment and disposal of mill slurry water, surface runoff, mine dewatering, and sanitary sewage, serving a gold mining and mill complex processing gold ore using the carbon-in- pulp (CIP) gold recovery process, located at Opapimiskan Lake, approximately 130 km north of Pickle Lake, as follows: Proposed Works A. TAILINGS MANAGEMENT AREA (TMA) Tailings Impoundment Area A Discharge Dyke for the thickened tailings up to elevation 312 m along the northwest, west and southwest boundaries of the TMA to facilitate initial thickened tailings deposition. Proposed increase to the storage capacity of the TMA from 17.3 to 32 million tonnes. This is to be achieved by implementing a thickened tailings disposal system together with a de-sulphurized process, which will render the tailings non-acid generating. Deposition Strategy The tailings will be stacked and a vegetative cover provided for closure. The tailings pond will be partially drained. The overall tailings deposition strategy is described in Golder (2009a) and summarized below: Partition TMA with a Separation Dyke to maintain a clear water pond downstream of the dyke for water management purposes Construct starter Discharge Dyke to elevation 312 m on competent ground on west end of TMA and commence thickened tailings deposition from the dyke in 2010.

  • The Big Hole: Environmental Assessment and Mining in Ontario
    THE BIG HOLE Environmental Assessment and Mining in Ontario Report prepared by MiningWatch Canada For the Canary Research Institute December 2014 With financial support from Mountain Equipment Co-op and the Salamander Foundation Introduction The history of large-scale industrial mining and refining in Ontario goes back nearly 200 years. Major mining camps have been developed at Sudbury, Timmins and Red Lake, and many small mines exploit more modest local resources. Mining’s historic legacy is one of dispossessing Indigenous peoples of their territories, of economic booms and busts and of substantial environmental degradation, perhaps most significantly, the extensive impacts of smelting in the area surrounding Sudbury. In 2013, Ontario produced $9.8-billion worth of minerals, with gold, copper and nickel making up 29%, 16% and 15% of the total value respectively.1 In 2011, 24,000 people worked in the mining sector, which, along with oil and gas, represented 1.4% of provincial GDP for that year.2 Recently there has been renewed interest in the sector from political leaders seeking a way out of the economic doldrums that have followed the 2008 recession and a decline in the manufacturing sector. Chromite, nickel and copper deposits discovered in the so-called Ring of Fire area of northern Ontario have helped fuel this attention. Industry and the provincial government portray the modern mining industry as a leading-edge actor that responsibly addresses health, safety and environmental challenges inherent in the sector. For example the Ontario Mining Association website states: With a clear focus on the future, Ontario’s dynamic mining industry is continually evolving to meet society’s changing needs and expectations.
