to the mine site. In 1981 the mine commenced production. The Polaris mine employed over 250 people. Although only 20 mine employees were from northern Canada, thirty percent of employment in Resolute was directly related to the mine.


Production

The Polaris mine produced over 21 million tonne of lead-zinc ore during the life of the mine, with a market value of over $1.5 billion. Concentrate from the mining operation was stored in a long warehouse, which was the largest structure in Nunavut.


Closure

Initially the mine was scheduled to close in 2001, however due to improved mining techniques, the mine life was extended one year to 2002.
