Millrock Finalizes Option Agreement With Inmet for Exploration of San Jose and Dry Mountain Porphyry Copper Prospects in Arizona

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 11, 2010) - Millrock Resources Inc. (TSX VENTURE:MRO) ("Millrock" or the "Company") announced today it has signed an option agreement with Inmet Mining Corporation (TSX:IMN) for the exploration of the San Jose and Dry Mountain porphyry-copper prospects in Arizona. Details of the agreement were first announced January 8, 2010 (here) upon signing of a letter of intent, and now with execution of the definitive agreement the partners are preparing to begin work. Geophysical surveys to refine drill targets are planned for spring 2010 with drilling to follow.

The San Jose and Dry Mountain properties are located on the highly prolific Safford and Morenci porphyry copper deposit trends which account for some 10 billion tons of past copper ore production. At San Jose, drilling by Noranda in the early 1990s identified a porphyry cell. Geochemical surveys indicate potential for a larger deposit nearby. At Dry Mountain, a strong copper-molybdenum geochemical anomaly 10 km in diameter has been outlined. Both properties are covered with overburden but bedrock is relatively near-surface.

The Option to Joint Venture agreement, which is subject to TSX Venture Exchange approval, gives Inmet the opportunity to earn a 70% interest in the two claim blocks by spending US$4.0 million on exploration and making option payments of US$300,000. The 2010 exploration expenditure commitment is US$500,000 and the initial payment is US$50,000. Millrock will be the operator in the first year of exploration and thereafter at Inmet's discretion.
