Between 1654 and 1845, a total of 11,300 tons of copper was produced from the mine. From 1904 the mine was run by the company Orkla Grube-Aktiebolag, and until 1987 a total of 24 million tons of pyrite was produced from the mine. In addition to sulphur, the pyrite contained about 2% copper, in addition to zinc and traces of silver and gold. The products were originally transported to the sea by horse and sledge during winter time. From 1908 the ore was transported by the Thamshavn Line, which was the first electrical railway line in Norway. The annual production was about 350,000 tons of ore during its final years.

In June 2005, the Attawapiskat First Nation voted in favour (85.5%) of ratifying the Impact Benefit Agreement (IBA). Construction of the mine began in February 2006 which created 3200 positions; mining and operations will create around 400 permanent positions. The Victor Mine is an open-pit mine, with a processing plant, workshops, and an airstrip located on site. By 2013-2014 royalties collected from De Beers Victor Diamond Mine amounted to $226.
