About Osisko Mining Corporation

Osisko Mining Corporation reports that it has received statements of offence relating to building activities carried out in 2010 in connection with the construction of its "green wall" in the Town of Malartic. Uncontested, the statements would total approximately $389,000 in imposed fines.

While Osisko will work with the authorities towards resolution of these statements of offence, the Company is seeking advice from its counsel in order to fully protect its rights.

The Company firmly believes that all construction activity related to the green wall was carried out under best practices to minimize the impact of the construction on the residents of Malartic.

Mining operations are unaffected and continue on a normal basis.
