(TSX:QMI)(FRANKFURT:QMI)(OTCQX:QNMNF) ("Queenston" or the "Company") announces that it obtained an interim order of the Ontario Superior Court of Justice on November 23, 2012.

The board of directors of Queenston has unanimously approved the Arrangement and will recommend that Shareholders vote in favour of the Arrangement.

Shareholders will receive 0.611 of a common share of Osisko for each Queenston Share held.

Each senior officer and each member of the board of directors of Queenston, holding in aggregate approximately 3% of the outstanding Queenston Shares, has entered into a voting and support agreement with Osisko pursuant to which each has agreed to vote the Queenston Shares held by them in favour of the Arrangement. In addition, Osisko has advised Queenston that certain shareholders of Queenston, holding in aggregate approximately 34% of the outstanding Queenston Shares, have also executed voting and support agreements with Osisko in which each has agreed to vote the Queenston Shares held by them in favour of the Arrangement. In aggregate, therefore, Osisko has received voting and support agreements representing approximately 37% of issued and outstanding Queenston Shares.

Queenston intends to mail the Notice of Special Meeting and Management Information Circular, together with a letter of transmittal and a form of proxy (collectively, the "Meeting Materials"), to Shareholders of record later this week.

If all necessary approvals are obtained and the conditions to the completion of the Arrangement are satisfied or waived, it is currently anticipated that the Arrangement will be completed prior to the end of December 2012.
