Du�an Berka, President & CEO of Megastar stated, �This alliance with Mantle offers an excellent opportunity to ensure a cost effective and comprehensive exploration effort across the entire area to the benefit of all parties concerned. The fact that Lundin Mining (TSX: LUN), one of the world�s premier mining companies, committed significant financial and technical resources to this region by partnering with Mantle was an important factor in our decision to proceed down this path.�

A definitive agreement, which will be subject to regulatory approval, is currently being drafted.� Mantle will be the operator and can earn a 60% interest in Megastar�s properties as follows:

• Payment to Megastar of $50,000 and the issuance of 50,000 shares of Mantle upon signing a definitive agreement;
• The issuance of 50,000 shares of Mantle nine months from signing a definitive agreement;
• Payment to Megastar of $100,000 and the issuance of 25,000 shares of Mantle on or before the first anniversary of� the signing of the definitive agreement; and
• Spending $2.25 million in exploration and development over a three-year period.

Upon earning a 60% interest, Mantle can increase its interest to 80% by spending an additional $1.0 million on the properties.� Mantle can then earn a further 10% (cumulative 90%) by completing a preliminary feasibility study.
