GREENLAND – Vancouver-based Hudson Resources has made the first shipment of anorthosite from its White Mountain mine 80 km southeast of Sisimut. The MV Happy Dragon bulk carrier was loaded with 14,400 tonnes of GreenSpar 250 anorthosite product and 56 tonnes of GreenSpar 90 (extremely fine).

Hudson mines a calcium feldspar which is comprised of 31% aluminum, 50% silicon and 15% calcium. The company says that unlike similar deposits which are small and contain too many impurities for commercial applications, its White Mountain deposit is massive and homogenous.

(Hudson notes on its website that the only larger anorthosite occurrence is on the moon.)

The White Mountain open pit mine has a potential life of 100 years, and holds permits for 50 years of operation. Hudson has a 10-year offtake agreement with a fiberglass producer. The deposit has a 43-101 compliant indicated resource of 27 million tonnes  and an inferred resource of 32 million tonnes. The deposit remains open in all directions along an 8-km strike length.

The mill flowsheet is simple: crushing and magnetic separation. The concentrate is stored as necessary and then shipped to customers. The mill received some upgrades while the ship was loaded. The changes included new gear boxes for one high pressure grinding roll, a new feed chute over a secondary HPGR.

Hudson’s investment has the potential to generate income from four product lines. Learn more at
