TAU Common Stock

Tintina Resources Inc. ("Tintina" or the "Company") (TSX VENTURE: TAU) is pleased to announce that it has received additional assay results for 11 drillholes from the 2011 drill program on its Sheep Creek Copper-Cobalt-Silver property ("Sheep Creek") located in Central Montana, USA (see Images 1& 2).

Highlights from the Upper Copper Zone in-fill drilling at Strawberry Butte:

--  Drill hole SC11-019 drilled 11.34 meters grading 2.09% Copper, 0.06%
    Cobalt and 11.8 g/tonne Silver and a second interval of 6.00 meters
    grading 1.31% Copper, 0.09% Cobalt and 27.7g/tonne Silver

--  Drill hole SC11-027 drilled 7.45 meters grading 2.52% Copper, 0.16%
    Cobalt, and 10.3 g/tonne Silver and a second interval of 2.95 meters
    grading 3.32% Copper, 0.18% Cobalt and 6.0 g/tonne Silver

--  Drill hole SC11-029 drilled 9.02 meters grading 2.66% Copper, 0.15%
    Cobalt, and 13.5 g/tonne Silver and a second interval of 3.01 meters
    grading 2.99% Copper, 0.13% Cobalt and 8.6 g/tonne Silver

The Company has two drill rigs completing in-fill and expansion drilling of the Upper Copper Zone (UCZ) massive sulfide on the Strawberry Butte target area. Results have been received from drill holes SC11-019, SC11-020, SC11-024, SC11-026, SC11-027, SC11-028, SC11-029, SC11-030, SC11-031, SC11-032, and SC11-033 (see Table 1 and Figure 2 - Drill Hole Location Map below). In addition, the Company has completed 16 drill holes for which assay results are pending and plans an additional 12 holes to further in-fill and expand the UCZ resource. The results of this drill campaign will be used to upgrade the UCZ resource to Measured and Indicated status. These results confirm the continuity of high copper grades throughout the UCZ and expand the known margins of the deposit.

(For previous Tintina Resources and historic results on the Upper Copper Zone at Strawberry Butte please see News Releases dated October 20, 2010; October 27, 2010; January 6, 2011; April 26, 2011, and May 4, 2011)

The Upper Copper Zone currently has an Inferred Resource containing 7 MMT grading 2.4% Cu, 0.12% Co, and 12.3 g/tonne Ag using a 1.5% Cu cut-off grade - see News Release dated January 6, 2011. Tintina Resources is completing in-fill drilling of the Upper Copper Zone (UCZ) massive sulfide at Strawberry Butte with the objective of bringing the UCZ Inferred Resource to Measured & Indicated status. Drilling on the edges of the deposit continues in order to determine the lateral extent of the deposit and is expected to expand the currently defined resource. The Company is also preparing an Inferred Resource estimate for the Lower Copper Zone massive sulfide at Strawberry Butte, and has initiated resource definition drilling on both the Lower Copper Zone and Middle Copper Zone massive sulfides on the Strawberry East target area where copper mineralization is associated with multiple mineralized horizons. The Company expects this drilling to expand the total resource base for the Sheep Creek property. The Company has also initiated a Preliminary Economic Assessment on the UCZ to determine project economics and has started collecting environmental baseline information in preparation for an environmental assessment report and project permitting.

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 is a growth company focused on the exploration and development of precious and base metal properties around the world. The Company's experienced Board of Directors and Management Team, are focused on advancing the Sheep Creek Copper-Cobalt-Silver 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 Project is located approximately 27 km north of White Sulphur Springs along a well maintained gravel road and within two miles of U.S. Highway 89. The Sheep Creek property consists of approximately 12,225 acres of fee simple land 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 an Inferred Resource on the Upper Copper Zone at Strawberry Butte (please see the Company's News Release dated January 6, 2011) and continues to evaluate four additional known 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.
