Millrock Reports on Drilling at Galiuro Copper Project, Arizona

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 30, 2012) - Millrock Resources Inc. (TSX VENTURE:MRO) ("Millrock" or the "Company") announced today that a hole being drilled on the Fourmile prospect on the Galiuro property was abandoned prior to reaching target depth. The work was being funded by Vale Exploration Canada Inc. ("VEC"), a wholly-owned subsidiary of Vale S.A. ("Vale") pursuant to an option agreement signed March 2, 2009. Vale has decided to terminate the option agreement.

Hole FM_1001 was a vertical hole being drilled to test a circular magnetic feature ringed by a strong conductive zone as identified by a ZTEM airborne geophysical survey. Intense argillic alteration is known from rock exposures and prior drilling on the west side of the structure. The hole was pre-collared to a depth of 453 m using a reverse circulation drill. Core drilling proceeded through Tertiary volcanic rock cover. Drilling conditions were very poor, and ultimately the hole was lost at a depth of 1,231.5 m. The hole was terminated before reaching target depth and the favourable Laramide-aged rocks expected beneath the Tertiary cover rocks.

The target at the Galiuro property is a large porphyry copper +/- gold deposit hidden beneath alluvium and Tertiary volcanic cover, similar in magnitude to the nearby Resolution deposit, which is being developed by Rio Tinto and BHP Billiton. The property is situated at the intersection of the Resolution and San Manuel / Kalamazoo porphyry copper trends. Because of the Tertiary volcanic cover, other companies have previously done little exploration work. Through careful geological mapping in combination with airborne magnetic and ZTEM geophysical surveys, Millrock has identified numerous targets that may represent porphyry deposits. With the withdrawal of Vale from the project, Millrock is seeking new partners to test the remaining targets.
