Osisko Mining Corporation and Clifton Star Resources, Inc. announced they have entered into a binding agreement regarding a joint venture on Clifton's Duparquet Project. Located near the town of Duparquet in Duparquet Township, Quebec, the Project is approximately 45 kilometres northwest of the city of Rouyn-Noranda and 90 kilometres northwest of Osisko's flagship Canadian Malartic construction-stage gold mine. The signing of the Joint Venture agreement is contingent upon the completion of due diligence by Osisko, Clifton entering into revised agreements in relation to the underlying option agreements governing Clifton's right to earn an undivided 100% interest in the Project on substantially the same terms as announced Clifton on October 26, 2009, and receiving the approval of the TSX Venture Exchange. The agreement provides: Osisko shall make contributions to the Joint Venture in the first year, which shall commence on January 1, 2010, of an aggregate minimum of $15 million. Thereafter, Osisko agrees: to contribute an aggregate of $15.7 million in earn-in payments to the Joint Venture in the second year, which shall commence on January 1, 2011; to contribute an aggregate of $23.6 million in earn-in payments to the Joint Venture in the third year, which shall commence on January 1, 2012; and to contribute an aggregate of $15.7 million in earn-in payments to the Joint Venture in the fourth year, which shall commence on January 1, 2013, and by making such payments (aggregate total of $70 million) Osisko shall earn a 50% interest in the Joint Venture over a period of four years (the 'Option Period'). Osisko shall have the right to increase the rate of earn-in payments and accelerate the term of the Option Period to acquire the 50% interest under the Joint Venture. Earn-in payments shall be used by the Joint Venture to fund the activities of the Joint Venture. Osisko will act as Operator of the Joint Venture during the Option Period and thereafter so long as Osisko has a 50% or greater interest in the Joint Venture.

Clifton Star Resources Inc., Annual General Meeting, Dec 14, 2009 Location: 700 – 595 Burrard St, Vancouver, British Columbia,Canada.

Clifton Star Resources Inc. announced that the recent assays obtained from the extended core sampling program at the Beattie gold deposit demonstrate the presence of broad zones hosting lower-grade gold that may be amenable to large-scale, open-pit mining methods. The company obtained data from 16 drill holes. Historical mining at the Beattie, Donchester, Central Duparquet, Duquesne, and Dumico deposits yielded large quantities of gold from high-grade veins using traditional underground mining methods. At least four major vein systems or zones are present: the North, South, RW, and RS. In the past, geologists submitted for assay only those portions of the drill holes cutting these four major zones, leaving the remainder of the drill core un-split and un-sampled. It is estimated that more than 80% of all core drilled at the Beattie-Donchester-Central Duparquet-Dumico went un-sampled. Clifton Star will be commissioning an updated NI 43-101 resource estimate for the Beattie-Donchester-Central Duparquet-Dumico-Duquesne deposits upon completion of the extended core sampling program. It is anticipated that this updated report will provide the first look at a shallow resource that may be amenable to large-scale, open-pit mining methods. The true widths are estimated at approximately 70% to 80% of the core lengths on average.
