Tintina Resources Inc.: More High Grade Drill Results From the Sheep Creek Copper-Cobalt-Silver Project

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/30/11 -- Tintina Resources Inc. ('Tintina' or the 'Company') (TSX VENTURE: TAU) is pleased to announce that it has received assay results for an additional 12 drill holes from this year's infill and expansion drill program on its Sheep Creek Copper-Cobalt-Silver property ('Sheep Creek') located in Central Montana, USA (see Figure 1).

Highlights from the Upper Copper Zone in-fill & expansion drill program at Strawberry Butte:

--  Drill hole SC11-055 drilled 20.22 meters (m) grading 2.13% Copper (Cu),
    0.07% Cobalt (Co) and 15.1 g/tonne (t) Silver (Ag)
--  Drill hole SC11-060 drilled 27.78 m grading 2.64% Cu, 0.06% Co, and 19.9
    g/t Ag
--  Drill hole SC11-064 drilled 8.42 m grading 4.80% Cu, 0.12% Co and 53.6
    g/t Ag
--  Drill hole SC11-072 drilled 21.03 m grading 2.70% Cu, 0.15% Co, and 15.7
    g/t Ag

The Company continues to receive assay results from an in-fill and expansion drilling program of the Upper Copper Zone (UCZ) Inferred Resource at Strawberry Butte. Results below are for 12 holes, and assays for 11 additional holes are pending. The results of this drill campaign will be used to upgrade and expand the UCZ Inferred Resource to Measured and Indicated status, expected late this year. In particular, 8 of the drill holes (indicated by (i)) lie outside the January 6, 2011 Inferred Resource boundary and may expand the resource. The Company also continues drilling with two drill rigs in the Strawberry East target area. The purpose of this drilling is to gain enough additional data to calculate inferred resource estimates for the Lower and Middle Copper Zones, and to further investigate the UCZ and other zones in the target area.

Holes with an '(i)' lie outside the January 6, 2011 Inferred Resource boundary and may expand the resource.

The UCZ at Strawberry Butte currently has an Inferred Resource containing 366 million pounds of copper in 7 MMT grading 2.4% Cu, 0.12% Co, and 12.3 g/t Ag using a 1.5% Cu cut-off grade - see News Release dated January 6, 2011. The Company has initiated a Preliminary Economic Assessment on the UCZ to determine project economics and continues collecting environmental baseline information in preparation for an environmental assessment report and a permit application for an exploration decline.

The Company has also completed an Inferred Resource estimate for the Lower Copper Zone massive sulfide at Strawberry Butte containing 255 million pounds of copper in 2.5 MMT grading 4.71% Cu, 0.06% Co, and 5.1 g/t Ag, and 0.35 g/t Au using a 1.5% cutoff grade - see news release dated August 17, 2011. Presently, the Company is carrying out resource definition drilling on both the Lower and Middle Copper Zones on the Strawberry East target area where copper mineralization is associated with multiple mineralized horizons.

Jerry Zieg, Vice President of Exploration for the Company is a Qualified Person for the purposes of National Instrument 43-101 and has reviewed and approved the information of a scientific nature contained in this news release. Assays for this program have been completed by ALS Chemex including duplicates, standards, and blanks for QA/QC purposes.

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.
