San Jose
Target: Millrock is targeting giant, high-grade porphyry copper (+/- gold and molybdenum) deposits at its San Jose project. The property is well located at the junction of the Safford and Morenci porphyry copper trends within 13 to 32 kilometers (8 to 20 miles) of these world class copper deposits. Morenci, one of the oldest and most productive open pit porphyry copper mines in Arizona, has production and reserves totaling up to 10 billion tons. The Safford deposits, upon which Freeport started production on in 2007, contain resources totaling at least six billion tons of copper ore in a series of four deposits. Geologic projections, as well as geochemical and geophysical surveys, indicate that a large porphyry copper deposit may be present beneath post-mineralization volcanic cover rocks and alluvium at San Jose. Millrock seeks to discover a large tonnage porphyry of sufficient grade to warrant extraction by open pit or block caving underground mining.
Location and Setting: The San Jose claim block is situated in the Safford and Morenci mining districts of southeastern Arizona. It is located in Graham County approximately 32 kilometers (20 miles) east of the town of Safford, 27 kilometers (17 miles) southwest of Clifton, and 161 kilometers (100 miles) northeast of Tucson. The topography is generally flat with rolling hills, at an approximate elevation of 1,006 meters (3,300 feet) ASL. Open scrub and mesquite is the only vegetation. Paved highway 191 passes across the claim block, as does a power transmission line.
Property and Agreement: The target concept was brought to the attention of Millrock by geologist Michael Schaefer of Tucson, Arizona, under a Finder's Fee agreement, and the property was subsequently secured with federal mining claims. Under the terms of this agreement, Millrock has paid Mr. Schaefer US$20,000 and issued 20,000 shares of the company stock. A further US$10,000 and 15,000 shares will be issued on each anniversary that Millrock holds claims in the Area of Interest defined in the Finder's agreement. If commercial production is achieved, Mr. Schaefer will be entitled to a payment of US$2 million. The property consists of 265 mining claims covering 5,450 acres, which were staked by the Company in February 2008. Millrock is the sole owner of the claims.
Geology and Mineralization: San Jose is located at the intersection of the Morenci and Safford porphyry copper trends. The trends are defined by a series of porphyry copper deposits, magmatic intrusions and structural features, and that manifest themselves in geological and geophysical analyses. Millrock's San Jose claim block is adjacent to two blind porphyry copper mineralization cells: San Jose and Sol. The San Jose deposit was discovered by Noranda in the 1990's. Sol was discovered by Amax in the 1970's. Past drilling suggest there is 60 to 549 meters (200 to 1800 feet) of post mineral cover at Millrock's San Jose claim block. Sol and San Jose have significant copper intercepts of 0.15 to almost 1% copper.
A copper - molybdenum biogeochemistry anomaly at the Company's San Jose claims defines a large area of potential covered mineralization starting at the known San Jose porphyry, and extending about two miles to the east and south.
A large magnetic susceptibility low, similar in size and character to the Morenci magnetic low, is covered by the San Jose claims. At Morenci, the magnetic low is thought to represent magnetite destruction associated with intense phyllic alteration. Surrounding magnetic highs are thought to represent a porphyry intrusive complex at depth. Gravity data defines a regional basement high, and GeoTEM, CSAMT and IP geophysical surveys define structural boundaries possibly associated with covered mineralization.
Exploration Program: While drilling could be immediately carried out, Millrock will further refine the existing targets first. The Company will investigate a variety of cutting edge geophysical technologies, and utilize the best system for detection and imaging of buried porphyry deposits. The selected surveys will be carried out in 2008. A major drilling campaign will be designed and planned for execution in early 2009.
