Northern Star Announces Management Changes

  Northern Star Mining Corp. (TSX VENTURE: NSM)(OTCQX: NSMSF) ("NSM" or the "Company") announces that Michel David has resigned as Chairman of the Board, President and CEO of NSM effective immediately. Mr. David will continue on as a director of the Company.

The Company has appointed Jonathan Awde, Vice-President, Corporate Finance, to serve as interim President and CEO of NSM. Mr. Awde has extensive financial experience and been instrumental in helping to raise over $80 million for the Company since joining the board of directors in 2007.

The Board is also reviewing NSM's overall personnel requirements with a view to expanding development of the Company's Midway gold project in Val d'Or, Quebec and fulfiling its goals of becoming a mid-tier gold producer and maximizing shareholder value. Further management related announcements are expected in the near term.

Mr. Jonathan Awde, spokesman for the Board, stated: "We would like to sincerely thank Mr. David for his valuable contribution to the Company for the past 8 years. Under Mr. David's leadership, NSM successfully assembled an impressive exploration land package in Val d'Or, Quebec and moved the Midway project from a pure exploration property to the Company's first gold pour (as announced on February 5, 2010).

The current management team of NSM is supportive of this change in leadership as the Company embarks on this important phase at its Midway gold project in Val d'Or, Quebec.

ON BEHALF OF THE BOARD

Jonathan Awde, President
