American Consolidated Update On Sierra Rosario Property 

VANCOUVER, BC - American Consolidated Minerals Corp. repored initial work is underway in preparation for an extensive exploration program at its Sierra Rosario silver/gold Property, located in the state of Sinaloa, Mexico.

The Company, along with its 50% operating partner, International Northair Mines Ltd. is preparing to conduct an exploration program at Sierra Rosario that will focus on the San Rafael Zone, as well as a number of associated attractive silver and gold targets on the property. This major exploration program is scheduled to begin in January 2012 and will include geological mapping, sampling, trenching and geophysics in order to establish drill targets.

"We're excited to get the project underway at Sierra Rosario," said Al Fabbro, President. "The San Rafael Zone is an excellent drill target and represents the type of bulk minable potential that drives shareholder value."

The Sierra Rosario Property was staked by Northair to cover the San Rafael gossan and a significant number of placer gold occurrences in numerous small drainages in the northern portion of the project area. Initial sampling of the San Rafael Zone by Northair returned an average value of 181 g/t silver and 0.32 g/t gold from 23 chip channel samples averaging 5 metres in length from quartz stockwork within a rhyolite porphyry.

Initial exploration was focused on the southern area of the concession, but later included construction of the first road access to the San Rafael Zone. Sampling completed along the road cuts in the San Rafael Zone included an additional 321 continuous channel samples along 3 meter sample lengths. In this area, two continuous channel samples measuring 34.8 meters and 27 meters in length averaged 192 g/t silver and 91.8 g/t silver, respectively - reinforcing the bulk minable potential of the zone.

During the exploration program at the San Rafael Zone, Northair discovered two small historical underground mines to the east which host manto-skarn base and precious metal mineralization. At the Dulces Nombres target, 35 underground chip samples from 1.5 to 3.0 metres in length averaged 0.71g/t gold, 263 g/t silver and 0.35% copper. At the La Descubriadora target, 19 chip samples of similar size, taken underground, averaged 0.40 g/t gold and 83.7 g/t silver. These discoveries provide significant upside exploration potential at Sierra Rosario, in addition to the prime San Rafael Zone target.
