Osisko to File Amended Technical Report

MONTREAL, QUEBEC--(Marketwire - July 11, 2008) - Osisko Mining Corporation ("Osisko") (TSX:OSK)(FRANKFURT:EWX) has filed an amended version of the Technical Report NI 43-101 Preliminary Assessment of the Canadian Malartic Gold Project ("Technical Report") to take into account comments made by the Autorite des marches financiers (Quebec) after a review of the report.

Statements have been added concerning the preliminary assessment and the economic viability of the resources, additional certificates of qualification have been added and the disclaimer of responsibility based on reliance on other experts was amended. The Technical Report, as well as the press release issued on March 28, 2008 should have incorporated the following disclosure: "The economic viability of mineral resources that are not mineral reserves has not been and cannot be demonstrated. Mineral resource estimates used in the report include inferred resources. These estimates are considered too geologically speculative to have any economic considerations applied to them that would enable them to be considered as mineral reserves. In addition, there is no assurance that the Preliminary Assessment will be realized and that further work will lead to mineral reserves that can be mined economically."

The amended version of the Technical Report may be found on SEDAR.com.
