![]() ![]() The sampling programme included lichens, Arctic char, sculpins, seaweed and blue mussels, which serve as key monitoring species in terrestrial and marine environments, respectively, supplemented with fresh water samples. This report provides an overview of the monitoring results and major findings. As a result of those risks, an environmental monitoring program was developed to discover and avoid unwanted impacts to the environment.Įnvironmental monitoring was conducted yearly at Nalunaq from 2004 to 2019 to monitor the environmental impact from mining during and after the mining operation. from traffic accidents or incorrect pumping of cyanide solutions. The risks were associated with discharge of mining process waste water or accidental spills of cyanide, e.g. II) The risk of discharge of cyanide in toxic concentrations to the environment during the mining period 2009-2013. The environmental risks were associated with discharge of waste water from the process and to spreading of metals as dust particles. The mining company Angel Mining Gold A/S closed its gold production in the Nalunaq area in November 2013 after which the area was decommissioned with a clean-up and restoration period lasting until August 2014.Īssociated to the mining activities, there were in particular two main environmental risks: I) The risk of spreading of released metals due to the crushing effects of the body rock, ore processing, stock piling, deposition of waste-rock and tailings and driving on the gravel road. Due to the use of cyanide to extract gold from the ore, strict control with the outflow of cyanide from the mine to the Kirkespir Valley is performed. A processing chamber was constructed inside the mountain and involved the carbon-in-pulp technology, which included the use of carbon and cyanide. In medio 2009, the mine re-opened now with full production of doré in Nalunaq. Rising oil prices and shipping costs made the economics progressively difficult and the mine closed with the last shipment of ore in March 2009. ![]() The ore was broken and shipped first to Europe and later to Canada for processing. The gold deposit at Nalunaq was discovered in 1992 and in 2004 the Nalunaq gold mine opened. The Nalunaq gold mine is located in Kirkespir Valley, 40 km northeast of the town Nanortalik, at the southernmost tip of Greenland.
