Nighthawk Notifies Warrant Holders of Approaching Expiry of Warrants

TORONTO, ONTARIO--(Marketwire - Sept. 11, 2012) -

NOT FOR DISTRIBUTION IN THE UNITED STATES OR THROUGH U.S. NEWSWIRE SERVICES

Nighthawk Gold Corp. ("Nighthawk") (TSX VENTURE:NHK) would like to remind holders of its September 23, 2010 and December 7, 2010 common share purchase warrants (the "Warrants") that the Warrants are set to expire at 5:00 p.m. (Toronto time) on September 23, 2012 (the "Exercise Deadline"). Any Warrants remaining unexercised after the Exercise Deadline will expire and be of no force or effect.

Currently, there are 15,547,267 Warrants outstanding at an exercise price of $0.14 per Warrant. Assuming all Warrants are exercised, net proceeds to Nighthawk would be $2.2 million.

How to Exercise Warrants

Warrant holders who wish to exercise their Warrants should instruct their investment advisor to effect an "immediate exercise". Once Nighthawk receives payment and the required documentation, the Warrants will be cancelled and the warrant holder will receive Nighthawk common shares.

Investors should consult with their investment advisor to confirm the time required to complete this process and other costs associated with the exercise, if any.

Warrant holders who hold a physical certificate wishing to exercise Warrants are required to provide Nighthawk with a certified cheque, bank draft or money order payable to Nighthawk Gold Corp., as well as surrendering the warrant certificate with the completed exercise form.

For assistance, contact Michael G. Leskovec, Chief Financial Officer of Nighthawk, directly at 1-416-628-5940 or by email at mgl@nighthawkgold.com.
