6 Ruby/Sapphire Resource The Aappaluttoq Ruby Project Indicated resource: Inferred resource: 189, g/t corundum (296.5 mio. carats) 77, g/t corundum (109.5 mio. carats) Amount of near-gem and gem quality: 31.3% ruby and 40.8% sapphire Source: True North Gems

7 Hudson Resources Anorthosite White Mountain New Mine! Source: Hudson Resources Website 2016 Anorthosite is used for Mine licence September 2015 start 2016 of construction open pit Capital investment of more than DKK 200 mill. 0.5 mill. tonnes mined every year, may increase to 1mill. tonnes Enough anorthosite for 120 years of mining 50 employees during the production phase (primarily locals) Production starts in 2017

8 Naajat Anorthosite Project Hudson Resources Anorthosite High Ca-feldspar Low Na Replacement for kaolin in E- glass Fiberglass Open pit Operation: Crushing-magnetic separation-milling-delivery 95% of anorthosite body untested Indicated resource: Inferred resource: 27 Mt (2,5% Na 2 O cut-off) 32 Mt (2,5% Na 2 O cut-off) *The resources are material containing less than 2.5% Na 2 O Photo: BMP

22 Gemstones Ruby/sapphire Diamonds Other

23 Industrial Minerals Anorthosite (feldspar) White Mountain Olivine Graphite

24 Olivine Mine Close to Nuuk (90 km) and Maniitsoq (82 km) Nuuk

25 Production from August ~ tons (2009) Resource: More than 100 mill. tons olivine (Pure forsterite) Resource for magnesium magnesite (MgCO 3 ) Seqi Olivine Mine The licence will soon be delivered back. A new licence round will be announced by the Government of Greenland

26 Graphite Former mines Eqalussuit Areas with graphite occurrences Amitsoq

27 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. Two mines will start production in 2017: Ruby/sapphire and feldspar. Exploration activity at present: Nickel, zinc, titanium-vanadium and gold. Coming mines: Zinc, REE, gold, titanium-vanadium and nickel. Photo: A. Clausen, MIMR
