Millrock Announces Resumption of Drilling at San Jose Copper Porphyry Project, Arizona

VANCOUVER, BRITISH COLUMBIA, September 6, 2011 - Millrock Resources Inc. (TSX-V: MRO) ("Millrock" or the "Company") is pleased to report that it has started a second phase of drilling at its San Jose project in the Safford area of southeastern Arizona.  Inmet Mining Corporation (“Inmet”) is funding the drilling as part of an earn-in option agreement.  Millrock is operator. Three holes will be drilled in the northern part of the San Jose claim block to test coincident magnetic high ZTEM conductor anomalies.  Six geophysical anomalies were identified during a recent airborne survey and three have been selected for this drill program. Based on the survey results, Millrock staked an additional 289 claims, substantially increasing the property holding.  The holes have been pre-collared using a reverse circulation rig, and will be completed with a core rig.  Hole depths may be up to 1,700 m each.

The San Jose project is positioned right at the intersection of the prolific Safford and Morenci porphyry trends. The Safford deposits, presently being actively developed by Freeport McMoran Copper & Gold, form a linear northwest striking trend. The San Jose project is located approximately six km from the Sanchez deposit at the southeast end of the Safford trend. Morenci is located approximately 30 km to the northeast. Together, Safford and Morenci account for approximately 10 billion tons of past copper production and future reserves and resources. A porphyry cell located on Millrock's claims was discovered by drilling done by Noranda Inc. in the early 1990s. ZTEM geophysical conductive zones surrounding magnetic highs are the primary target of the current drilling program.  The geophysical signature appears very similar to that reported over the Safford deposits.

The agreement with Inmet includes the Dry Mountain claim block, which is located 20 km to the southeast of San Jose on the Morenci Trend; a geochemical anomaly measuring approximately 10 km in diameter is present. The multi-element anomaly is strong in copper and molybdenum. The anomaly appears to emanate from coincident ZTEM-Mag signatures.  The area is completely covered in overburden. Millrock recently completed additional biogeochemical sampling and is formulating drill plans.

The San Jose and Dry Mountain projects are the subject of an option agreement with Inmet. Under the terms of the Agreement Inmet has the opportunity to earn a 70% interest in the two claim blocks, San Jose and Dry Mountain, by making US$4.0 million in exploration expenditures and by making option payments of US$300,000.
