About Tintina

Tintina Resources Inc. is a growth company focused on the exploration and development of base and precious metal properties around the world. The Company's experienced Board of Directors and Management Team are focused on advancing the Sheep Creek Cu-Co-Ag property in Montana towards a production decision. The Company is also exploring an impressive portfolio of gold and base metal projects in Alaska, including the Colorado Creek gold project located in southwest Alaska in the same region as the 40 million ounce Donlin Creek project.

About Sheep Creek

The Sheep Creek deposit is located approximately 17 miles north of White Sulphur Springs within two miles of U.S. Highway 89 along a well-maintained gravel road.

The Sheep Creek property consists of approximately 12,225 acres of fee simple lands and mining claims in central Montana. The property contains sediment- hosted zones of massive sulfide mineralization originally explored by Cominco American Inc. and BHP during the 1980's and early 1990's. Historical drilling encountered significant zones of strata-bound copper sulfide with associated cobalt and silver mineralization in multiple, bedded massive pyrite horizons in the lower part of the Precambrian Belt Supergroup. This same stratigraphic unit hosts the famous Sullivan zinc-lead-silver deposit in southeastern B.C. In a short period of time the Company has been able to establish Inferred Resources on the Upper & Lower Copper Zones at Strawberry Butte (please see Company News Releases dated January 6, 2011 & August 17, 2011). The Company continues to evaluate several tabular mineralized zones along a four kilometer strike length. The Company has two drill rigs on site and will continue drilling over the course of 2011.

Tintina is preparing an advanced underground exploration proposal which includes an evaluation decline and ancillary facilities, all located on private land in Meagher County, for presentation to the State's appropriate authorities.

About Mining in Montana

Montana has been known as a mining state for a well over 100 years. Today, more than two dozen mining operations are active making mining a cornerstone contributor to the State's GDP. Tintina has met with State regulators and looks forward to presenting the Sheep Creek project, as an underground mine with a small footprint located on private land. The project continues to benefit from broad local community support.
