DRILLING COMMENCES AT MANIITSOQ Ni-Cu-Co & PGE SULPHIDE PROJECT, SOUTHWEST GREENLAND

Vancouver, British Columbia, June 24, 2013 – North American Nickel Inc. (TSX VENTURE: NAN) (OTCBB: WSCRF) (CUSIP: 65704T 108) (the “Company”) is pleased to announce that diamond drilling has begun on its 100% owned Maniitsoq project. A minimum of 3,000 meters is planned and it will focus on testing high priority VTEM electromagnetic (EM) anomalies defined within the 70 km-long Greenland Norite Belt and on following up the multiple high-grade nickel sulphide intersections drilled by NAN last year at Imiak Hill and the Spotty Hill discovery.

NAN CEO Rick Mark states: “The full team is now in Greenland and helicopter supported fieldwork, including channel sampling and ground truthing of anomalies is underway. The drill team has also begun its work and is supported by a second helicopter. The plan is flexible allowing us to stay in areas that produce core of interest to the geologists on site. COO Neil Richardson is leading the crew. We are planning to ship core samples weekly out of Maniitsoq. It will be an exciting summer for all of us.”

The drilling will be done with a helicopter-portable drill contracted from Westcore Drilling Ltd. A borehole pulse EM (BHEM) system, supplied and operated by Crone Geophysics & Exploration Ltd., is on site. It is anticipated that most holes will be surveyed with the BHEM system, which greatly increases the search radius of the holes, allowing geologists to target follow-up holes more precisely. The system can also be used for surface surveying in the event that an EM anomaly requires more detailing prior to drilling.

Throughout the summer field crews will continue to map, prospect, sample and evaluate VTEM anomalies on surface. Approximately 660 line-km of VTEM helicopter time domain EM surveying is planned for later in the season. The survey will be flown by Geotech Ltd. and will cover several areas of interest outside the main norite belt.

Details on the 2012 Imiak and Spotty Hill intersections can be found in NAN’s press release dated January 15, 2013. An outline of some of the priority targets for this year’s drill campaign is given in NAN’s press release dated March 20, 2013.
