(OSK:TSX, “Osisko” or the “Corporation”) is pleased to announce that  it has acquired though staking a significant land position in the Lebel-sur Quévillon area of the Abibiti Greenstone Belt of Quebec, located approximately 110 kilometers west of the Windfall Lake project.  Map staking of 2942 claims was recently completed and resulted in the acquisition of a large land package covering 157,000 hectares (157 sq. km).
