Tests up to 35 % Ni & 34 % Cu
Vancouver, British Columbia, June 11, 2013 – North American Nickel Inc. (TSX VENTURE: NAN) (OTCBB: WSCRF) (CUSIP: 65704T 108) (the “Company”) is pleased to announce that it has received a report on the results of mineralogical studies performed by SGS Canada Inc. (“SGS”) on three samples of mineralized drill core selected by NAN from NAN’s 100% owned Maniitsoq Ni-Cu-Co-PGE sulphide project in southwest Greenland. Two of the samples came from the Imiak Hill zone and one from the Spotty Hill zone.
The objectives of the study were to identify and quantify the nickel, copper and cobalt-bearing minerals within the samples and to determine the liberation and association characteristics of the nickel and copper sulphides.
Highlights and selected results are presented below.
John Pattison, North American Nickel’s Chief Geologist states: “QEMSCAN is a new technology that gives us a detailed picture of the mineralogy of our sulphide mineralization and host rocks and how it might affect the metallurgy in a mining/processing scenario. At this early stage of exploration it is very helpful for management and investors to know that, based on the mineralogical characteristics of the samples analyzed, there is potential for high nickel recoveries from both the Imiak and Spotty Hill zones.”
QEMSCAN REPORT HIGHLIGHTS
• All three samples show high potential nickel recovery. Mineralogically limiting grade-recovery curves indicate maximum potential nickel grades of 35% at recoveries of 84 to 87%.
• Pentlandite is the main nickel-bearing mineral and it contains 95.5 to 96.3% of all the nickel in the samples. Silicate hosted nickel comprises less than 1% of all the nickel.
• Pentlandite P80 grain sizes range from 53 to 65 µm.
• Total potentially floatable pentlandite ranges from 96.3 to 97.6%.
• All copper is hosted by chalcopyrite. Chalcopyrite P80 grain sizes range from 30 to 40 µm.
• Potential recoveries for copper are variable across the samples. Mineralogically limiting grade-recovery curves indicate maximum potential copper grades of 34% at recoveries of 52 to 77%.
• Total potentially floatable chalcopyrite ranges from 87.1 to 95.4%.
• Pentlandite and pyrite are the main hosts of the cobalt in the samples.
