Premium Exploration Announces $5,000,000 Joint Venture Agreement for its Chrome Mountain PGM Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 5, 2007) - Premium Exploration, Inc. (TSX VENTURE:PEM) ("Premium") (http://www.premiumexploration.com) is pleased to announce a Joint Venture Agreement on its Chrome Mountain Platinum Group Metals project with Beartooth Platinum Corporation ("Beartooth") (TSX VENTURE:BTP). Premium's Chrome Mountain PGM Project ("Project") is located in the Stillwater Complex in the State of Montana, United States of America. Under the terms and conditions of the Joint Venture Agreement Premium will contribute its Chrome Mountain Project exclusive of the Pine Claim Gold Shear Zone to the Joint Venture, which Premium will retain and explore independently of the Joint Venture.

The new Joint Venture Agreement follows the successful completion of the 2006 exploration program. The 2006 work included 2,300 soil samples and documented a major Cu-Ni-PGM anomaly with soil grades up to 1.4 grams PGM from Premium's property (See Premium Exploration Press Release May 24, 2007).

For participating in the Joint Venture Premium will receive the following:

1) Reimbursement of 50% of its previously incurred exploration expenditures on the Chrome Mountain Project.

2) Upon Beartooth completing three million dollars (US$3,000,000) in exploration expenditures on the Project to vest its 50% interest in the project ("Initial BTP Vesting Expenditures"), Premium, can at its option maintain its 50% interest in the project by paying for its pro-rata share of exploration expenditures above the Initial BTP Vesting Expenditures if Premium declines the Participatory Option, Beartooth can earn an additional 30% by spending an additional US$2,000,000. Upon Beartooth's completion of five million dollars (US$5,000,000) of cumulative exploration expenditures on the Project by January 1, 2011, Premium will retain a twenty percent (20%) carried interest in the Project and Beartooth will own an eighty percent (80%) participatory interest in the Project.

3) A one percent (1%) Net Smelter Royalty ("NSR") on both Premium's and Beartooth's properties.

Mr. Del Steiner, President and CEO of Premium, states, "Premium is very excited to be working with Beartooth Platinum Corporation. Along with Beartooth's aggressive drill program they bring substantial Platinum Group Metals expertise and resources to our Chrome Mountain Project. We look forward to working with them to fully develop the potential of the Chrome Mountain Project."

Mr. Michael D. Johnson, P.Geo, President and CEO, commented, "This agreement is an important step in the exploration and development of the B-Chromitite PGM zone. The agreement increases the total strike length of the prospective horizon available for exploration by Beartooth to 20 kilometers, of which 15 kilometres has now been covered by soil geochemical surveys. The resultant soil anomaly is clearly reflective of continuous bedrock PGM mineralization, which we believe is associated with the B Chromitite. We are extremely excited by the results of last year's work, and we look forward to this year's drilling campaign where we will test this high quality target along much of its strike length and which we expect to commence at the end of June. Beartooth anticipates 20,000 feet of drilling which is double that accomplished in 2006."

Overview of the Stillwater Complex and Chrome Mountain Project:

The Chrome Mountain Project is located in the Stillwater mafic intrusive complex 120 kilometres south of Billings, Montana. The property parallels the JM reef, currently being mined from two sites by the Stillwater Mining Company (NYSE:SWC) for approximately 8 1/2 kilometers on the "B" Chromites.

Stillwater Mining Company produced approximately 500,000 oz of PGM's in 2006. The JM reef runs the entire 41 kilometre length of the Stillwater Complex, and models the Merensky reef in the Bushveld Complex in South Africa; the B Chromitites at Stillwater are thought to mimic the UG2 Chromitites, also in the Bushveld. The UG2 chromitites account for approximately 64% of the PGM production from the Bushveld.
