The first excavations in Maamorilik took place from 1938, possibly earlier, with operations continuing until 1945, and again from 1973 to 25 July 1990 when the mine was closed. During seventeen years of operation, the mine yield of zinc
ore amounted to 12 mln tonnes. The disposal of tailings left a legacy of
water pollution, contaminating surrounding bodies of water and marine organisms, long after the mine's closure. For years, it was recommended not to collect and consume
blue mussels within a 30 km radius of the mine site due to elevated lead concentrations. For the first 10 years of operation, disposal of waste rock outside the mine was unregulated and 2 to 3 million tonnes of waste rock containing lead and zinc were left in four dump sites.
Reactivation In 2008 keeping the relatively new
Qaarsut Airport open. Proceeds from mineral resources exploitation will provide Greenland with a counterbalance to the lump-sum
subsidies from
Denmark. The operations were carried out by Angel Mining plc, a
UK-registered company. As of April 2010, work continues on widening of the mine entrance to the required . with zinc and iron ore reserves expected to last for 50 years. Prospective employment is estimated at 110 people. ==Transport==
