VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 13, 2011) - Tintina Resources Inc. ("Tintina" or the "Company") (News - Market indicators) is pleased to announce that it has received additional assay results for a further four drill-holes from this year's program on its Sheep Creek Copper-Cobalt-Silver property ("Sheep Creek") located in Central Montana, USA (To view Images 1,2 & 3, please visit the following link: http://media3.marketwire.com/docs/tau713i.pdf).

Upper Copper Zone (UCZ) at Strawberry East:

• Drill-hole SC11-049 intersected 7.19 meters (m) grading 2.22% Copper (Cu), 0.08% Cobalt (Co), and 12.1g/tonne (t) Silver (Ag).

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

• Drill-hole SC11-045 intersected 3.10 m grading 2.13% Cu, 0.03% Co and 9.2g/t Ag

• Drill-hole SC11-046 intersected 24.39 m grading 2.20% Cu, 0.14% Co and 14.2g/t Ag

• Drill-hole SC11-047 intersected 11.20 m grading 1.52% Cu, 0.11% Co, and 11.6 g/t Ag

The Company has also begun drilling with two drill rigs in the Strawberry East target area, a full two miles east of the Strawberry Butte mineralization. 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 as well as explore other potential zones. The first hole of the 2011 drill campaign in the Strawberry East area encountered significant copper mineralization in the UCZ, the first time this particular zone has produced ore grades and thicknesses of copper mineralization. In addition, hole SC11-049 encountered a thin zone of high grade copper mineralization in the Lower Copper Zone (LCZ) as well.

The Company has also completed in-fill and expansion drilling of the Upper Copper Zone (UCZ) massive sulfide on the Strawberry Butte target area where it has assays pending for 26 holes. The results of this drill campaign will be used to expand and upgrade the UCZ resource to Measured and Indicated status.

(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; May 4, 2011; June 21, 2011 and June 28, 2011.) 

The UCZ at the Strawberry Butte target area 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. The Company has 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.

The Company is also preparing an initial 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 new Upper Copper Zone mineralization on the Strawberry East target area will be followed up with subsequent drilling.

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 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 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.
