The Company is pleased to report that the exploration work, as set out in the Company's planned 2012 work program, has been completed. Tintina has drilled approximately 46,332 meters (including 43,353 meters of in-fill drilling) on the Black Butte Copper project and has completed an airborne geophysical survey over approximately 120 square miles (311 sq. km). With the completion of this drill program, a number of important milestones have been achieved including: expansion and in-fill drilling of the Johnny Lee deposit; exploration for new mineralized targets; and the addition of the recently announced Inferred Resource at the Lowry Middle Zone (see press release dated March 19, 2012). As new milestones are achieved, and as work at Black Butte Copper progresses, the Company is gearing up for one of the most significant milestones to date - the release of the Preliminary Economic Assessment, which management expects to be released in July, 2012.

"Having completed the planned in-fill drill campaign on the Johnny Lee Deposit and upgrading of the 43-101 resource to include the Lowry Middle Zone, the Company is in a position to complete and release the PEA on the Black Butte Copper project by the end of July, 2012. The Company has also initiated environmental baseline studies and commenced soliciting bids for the upcoming feasibility study on the Black Butte Copper project," said Raj Chowdhry, CEO and Executive-Vice-Chairman of the Company.

The information from the airborne geophysical survey will provide the Company with a formidable toolkit for discovering new resources in the Black Butte area. Geophysical results clearly define trends consistent with significant mineralization seen in the past drill results at Black Butte Copper and provides the Company with excellent future drilling targets. Tintina Resources can now add this wealth of knowledge to the geologic setting gained from recent drilling.

The Company is also pleased to announce the commencement of the first exploration drill campaign at its Baird project in Alaska, where several kilometric-scale copper-zinc surface anomalies will be tested with 2,500 meters of drilling. The Baird property consists of an 80,600 acre property located in northwest Alaska, U.S.A. between the famous Red Dog Mine, one of the largest zinc producers in the world, and the Ambler mining district being explored by NovaCopper Inc. The Company believes the large scale copper-zinc mineralized exposures at Baird could lead to a significant new discovery. This drill program will focus on previously identified mineral targets at the Omar, Deadfall, and Frost targets. The Omar target exhibits mineralization over an area measuring 4km by 2km (2.5mi by 1.24mi) with coincident copper and zinc soil and rock chip anomalies. Historic drilling results showed significant bedrock mineralization including:

• 22.8m @ 3.99% Cu*
• 6.1 m @ 9.37% Cu*
• 7.32m @ 2.95% Cu*

(*- Historical results. These results are non NI 43-101 compliant. The reader is cautioned that such results are historical in nature and should not be relied upon.)

The Deadfall target consists of a 4km (2.5mi) long zinc and copper anomaly. Although no drilling has been completed on this target, channel sampling of outcrops identified significant bedrock mineralization including continuous channels samples as follows:

• 36m @6% Zn and 21.7 g/t Ag
• with 12m @ 10.1% Zn and 42.4 g/t Ag

Tintina Resources is in the process of setting up the camp and mobilizing a drill rig to the property to commence the 2,500 meter exploration drill program in early July, 2012.

About Black Butte Copper Project

The Black Butte Copper Project is located approximately 27 kilometers (17 miles) north of White Sulphur Springs, Montana, and lies along a well-maintained gravel road within two miles of U.S. Highway 89. The property, originally explored by Cominco American Inc. and BHP during the 1980s and early 1990s, consists of approximately 12,225 acres of fee simple lands and mining claims and contains sediment-hosted zones of Cu-Co-Ag syn-sedimentary massive sulfide mineralization. The Company has completed over 46,000 meters of drilling since initiating work in September, 2010 and has established Indicated and Inferred Resources on the property including the Johnny Lee Deposit Upper Zone, Johnny Lee Deposit Lower Zone and the Lowry Deposit Middle Zone (please see Company News Release dated January 13, 2012, and Table 2).

About Mining in Montana

Montana has been 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 Gross Domestic Product (GDP). Tintina has met with State regulators and looks forward to presenting the Black Butte Copper project as an underground mine with a small footprint located on private land. The project continues to benefit from broad local community support.
