Millrock Provides Update on Strategic Alliance with Vale: Five Porphyry Copper-Gold Projects Generated in Alaska

VANCOUVER, BRITISH COLUMBIA, December 20, 2012 - Millrock Resources Inc. (MRO - TSX-V) (“Millrock” or “the Company”) announced today that the strategic partnership between the Company and Vale Exploration USA, Inc., a wholly-owned subsidiary of Vale S.A. ("Vale"), has concluded.  Through the course of the program, Vale invested $1.4 million for research and reconnaissance exploration for porphyry copper-gold deposits in Alaska.  The work led to recommendations for five Designated Projects, one of which was accepted by Vale:  the AUDN project.  Under a separate budget Vale funded $700,000 for soil geochemical and ZTEM-magnetic airborne geophysical surveys at AUDN.  However, Vale has also advised that they will not fund further work on AUDN. Gregory Beischer, President & CEO of Millrock stated, “While Vale will not continue with the strategic partnership, we are pleased with what has been accomplished.  As a result of the work, Millrock has generated five highly prospective projects, two of which have been advanced to the drill-ready stage.  There is an excellent chance that we will find other partner companies to test the prospects we developed with Vale.”
