experience;

- Jean-Sebastien David - Vice President, Sustainable Development;

- July 2007 updated inferred resource of 8.4M oz Au, adding nearly 2M ounces of gold to the deposit from the December 2006 inferred resource (6.5M oz Au);

- Graduation to the Toronto Stock Exchange from the TSX Venture in November 2007;

- Over $200M of equipment purchased to date, including critical long lead items: 38' SAG mill, three 24' ball mills, mining fleet (twelve 227 tonne haul trucks, two electric shovels);

- Completion of a 233,000 metre/1020 drill hole infill program to provide the basis for the pending measured and indicated resource calculation;

- Acquisition of land for the relocation area, and commencement of construction of new lots;

- Encouraging new exploration results from South Barnat, Western Porphyry, Southeast Extension, Jeffrey Zone and Norrie Zone have been announced during the last six months;

The Company is on schedule to release the measured and indicated resource on the Canadian Malartic deposit in July 2008, and also to complete feasibility work and deliver the Definitive Feasibility Study (DFS) by Q4 2008.

The relocation program, mine engineering and new exploration works are all progressing according to schedule.

Company President Sean Roosen states: "Osisko is well on track to become what we anticipate will be the next mid-tier gold producer in Quebec. Our name change to Osisko Mining Corporation reflects the rapid and successful progression we have had over the last year towards becoming a new developer. Osisko is quickly approaching significant milestones that, successfully crossed, will allow the Company to become a premium gold producer with a low capex, low opex, which is on low-cost Quebec Hydro grid power and is located in the one of the best mining jurisdictions in the world."
