Nanisivik (Inuktitut syllabics: ᓇᓂᓯᕕᒃ, translation for the place where people find things) was a company town which was built in 1975 to support the lead-zinc mining and mineral processing operations for the Nanisivik Mine, in production between 1976 and 2002. The townsite was located just inland from Strathcona Sound, about 20 km (12 mi) east of the community of Arctic Bay in the Canadian territory of Nunavut.
There is a port and dock about 3.7 km (2.3 mi) north of the former mine site which was used for shipping concentrate from the site, and receiving supplies (73°04′08″N 084°32′57″W / 73.06889°N 84.54917°W). It is currently used by the Canadian Coast Guard for training.[2]
Nanisivik Airport located 8 NM (15 km; 9.2 mi) south[3] was used as the main airport for Arctic Bay until 2010 when the lengthened Arctic Bay Airport took over. The airport is about 19 km (12 mi) directly southeast of Arctic Bay but the road between them is 32 km (20 mi).[4]
Geology
The ore deposit resides within dolostone from the Society Cliffs Formation covered with dolomite shale from the Victor Bay Formation, which together form the Uluksan Group and reside on top of silty shale. The ore is believed to have formed when hot saline water bearing the metal ions of sodium, calcium, chlorine, and sulfate mixed with cooler carbonate-rich brine in the presence of natural gas or methane, which produced hydrogen sulfide through reducing the sulfate. The hydrogen sulfide then reacted with the metals to form the sulfides of marcasite (FeS2), pyrite (FeS2), sphalerite ((Zn,Fe)S), and galena (PbS). The Nanisivik deposit once contained 60 million metric tons of pyrite and 12 million tons of Lead-Zinc ore.[5]
Mineralogy
The Nanisivik mine is known for its diversity of unusual pyrite pseudomorphs after marcasite and pyrrhotite.
History
Discovery
Arthur English was a prospector on the steamship of Captain J. E. Bernier as part of the Canadian Geological Survey in 1910. They wintered the 1910-11 winter in Arctic Bay (20km south-east of Nanisivik). In 1911 Arthur English published his discovery of a "very large body of ore" at Nanisivik. [5]
Development
J.F. Tibbitt and F. McInnes traveled form Churchill, Manitoba to Nanisivik by Bobsled (3,000,km) and staked their claims in 1937, but were unable to develop them. In 1956 R. G. Blackadar and R. R. H. Lemon published maps of the region for another Geological Survey of Canada. Soon thereafter Texas Gulf Sulfur (latterly Texasgulf Inc., now broken up into bits such as Intrepid Potash) evaluated the region and staked 15 claims. Extensive drilling and exploration over the next decade led to the procurement of heavy equipment in 1970 and bulk metallurgical testing. Mineral Resources International of Calgary, Alberta traded the rights to a sulfur deposit in Mexico for a long term option on the Strathcona Sound property, which eventually translated into 54% ownership of Nanisivik Mines Limited. Strathcona Mineral Services Limited was hired to run the mine as an independent manager and successfully initiated production.[5]
Operation
The mine opened in 1976 and yielded primarily zinc, however silver and lead were collected as byproducts. It is located in 500m thick permafrost 700km north of the arctic circle and operated year-round through accumulating ore during the winter and shipping in the summer (July-Nov). Annual production totaled 125,000 tons of ore, which was sold to European smelters via Belgium.
Conwest Exploration Company Ltd. eventually acquired the mine. [5]
Mine closure
Since the closure of the mine in 2002, reclamation has been ongoing and the town is abandoned. Residents of Arctic Bay had hoped that the Government of Nunavut would be able to find a new use for the former townsite, potentially a trades training centre. They had also hoped to be able to move some of the buildings and equipment to their community.[6] Due to heavy lead-zinc contamination, this was not possible and the homes have been demolished.[7] Local telephone service was discontinued on February 19, 2007 on approval from CRTC.
As of the 2006 census the population was 0, a drop from the 2001 census with a population of 77.[8][9]
Conversion to naval station
On August 8, 2007, CBC News reported that Canadian Forces documents showed plans to convert the site into a naval station. The plan, which would turn the former mine's existing port into a deepwater facility, would cost $60 million and it was expected that Prime Minister Stephen Harper would make an announcement during his stop in Resolute.[10]
On August 10, 2007, Prime Minister Stephen Harper announced construction of a new docking and refueling facility in Nanisivik for the Canadian Forces, in an effort to maintain a Canadian presence in Arctic waters during the navigable season (June–October). The choice for Nanisivik as a site was partially based on its location within the eastern entrance to the Northwest Passage, and the existence of a deep-water berthing facility at the site, as well as a "jet-capable" airstrip nearby.
Detailed planning for the project began in August 2007, with environmental studies and assessments being carried out in the summer of 2008. Construction at the site is expected to begin in the summer of 2010, with early operating capability available in 2012. The facility is planned to be fully operational by 2015.[11]
Once completed, the naval station will likely be home to the proposed Arctic Off-Shore Patrol Ships under the current Harper government plan.[12][13] These ships will have ice-breaking capability and help the current government's goal to enforce Canada's sovereignty over the region. These ships will likely allow the Victoria-class submarines to travel in the Arctic regions.
The facility was to have an initial operational capability in 2012, and be fully complete in 2015 but is behind schedule.[14][15] Development is being delayed because environmental cleanup has been delayed as much as possible by Breakwater Resources Ltd., owned by Nyrstar N.V.[16]
In 2011 and 2012, the government started backing down on the Nanisivik conversion plans, explaining that construction in the far north is too expensive. The station will be primarily used for refueling Arctic patrol and other government vessels, and construction was expected to begin in 2013, with the station operational by 2016, [17] however those dates are unlikely to be met.
