Olivine Mine
Close to Nuuk (90 km) and Maniitsoq (82 km)
Nuuk • Production from August 2005 – 2009. ~400.000 tons (2009)
• Resource: More than 100 mill. tons olivine (Pure forsterite)
• Resource for magnesium –
magnesite (MgCO3)
The licence will soon be delivered back . A new licence round will be announced by the Government of Seqi Olivine Mine Greenland Graphite

Amitsoq Concluding remarks
The geological environments and the related mineral deposits are in many ways similar to that found world-wide, meaning that the potential for new mineral discoveries are good and can sustain mining.
Greenland has a variety of mineral potential (including giant deposits). At present the best potential is for iron-alloys, base metals, nickel, specialty metals, precious metals and some industrial minerals.
