Mill throughput is expected to stabilize at approximately 55,000 tonnes per day in 2014 with the completion of optimization programs currently in progress. Together with increased contribution from higher grade material in the now accessible northern pit wall, it is anticipated that gold production for the current year will increase to between 525,000 to 575,000 ounces, an increase of 11% to 21% over record 2013 production of 475,277 ounces gold.

Canadian Malartic has proven & probable in-pit reserves of 9.37 million ounces, with a mine life of 14.2 years based on a 55,000 tonne per day (tpd) milling rate. Average gold production is forecast at 610,000 ounces per year over the next five years (2014 - 2018) at cash costs of US$516 per ounce, with an average of 597,000 ounces per year gold production over life of mine at cash costs of US$525 per ounce. The mine is expected to have an average head grade of 1.09 g/t Au over the next five years, and 1.03 g/t Au over the mine life, with average metallurgical recovery of 89.2% over the mine life.

Sean Roosen, President and CEO of Osisko stated: "Canadian Malartic is continuing on its record setting pace for 2014. March was another strong month of gold production, despite an unanticipated four day shutdown of the mill circuit to repair loose liners in the SAG mill. Despite this, we have achieved another record for quarterly gold production, again underlining Canadian Malartic's value to all shareholders with its top class gold production and strong cash flow.

Last week, Osisko announced a partnership agreement (the "Arrangement") with Yamana Gold, unanimously supported by Osisko's board of directors which determined that the Arrangement is in the best interests of Osisko and its shareholders and will recommend that Osisko shareholders vote in favour of the Arrangement.

I would like to remind shareholders of the unanimous recommendation of Osisko's Board of Directors to shareholders that you reject Goldcorp's inadequate hostile offer, and not to tender your shares to their bid."

Reject the Inadequate Goldcorp Offer

As previously disclosed, the Osisko Board of Directors has unanimously recommended that Osisko shareholders reject the hostile take-over bid initiated by Goldcorp and not tender their Osisko shares to the Goldcorp offer. The Osisko Board determined that the Goldcorp offer fails to adequately compensate Osisko shareholders for, among others things, the strategic value of Osisko's world-class asset base, the significant upside potential of Osisko's Canadian Malartic Mine, or the increased risk inherent in Goldcorp common shares. The full basis for the Osisko Board's recommendation is available in a Directors' Circular, a copy of which is available online at www.osisko.com.

Shareholders who have questions or who may have already tendered their shares to the Goldcorp Offer and wish to withdraw them, may do so by contacting our Information Agent, Laurel Hill Advisory Group at:

Forward-Looking Statements

Certain statements contained in this press release may be deemed "forward-looking statements". All statements in this release, other than statements of historical fact, that address events or developments that Osisko expects to occur, are forward looking statements. Forward looking statements are statements that are not historical facts and are generally, but not always, identified by the words "expects", "plans", "anticipates", "believes", "intends", "estimates", "projects", "potential", "scheduled" and similar expressions, or that events or conditions "will", "would", "may", "could" or "should" occur including, without limitation, the satisfaction of all technical, economical, regulatory and financial conditions in order to complete the Arrangement between Osisko and Yamana, the stabilization of mill throughput, the completion of optimization programs, the decrease of costs and increase of grade and gold production, Osisko's view on the quality and the potential of its Canadian Malartic asset and on Goldcorp common shares and offer, and that mining of the deposits identified in this press release will be executed timely and fully, and will return values identified in the foregoing estimate. Although Osisko believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results may differ materially from those in forward-looking statements.

Factors that could cause the actual results to differ materially from those in forward-looking statements include gold prices, access to skilled consultants, mining development and construction personnel, results of exploration and development activities, Osisko's limited experience with production and mining operations, uninsured risks, regulatory framework and changes, defects in title, availability of personnel, materials and equipment, timeliness of government approvals, actual performance of facilities, equipment and processes relative to specifications and expectations, unanticipated environmental impacts on operations market prices, continued availability of capital and financing and general economic, market or business conditions. These factors are discussed in greater detail in Osisko's most recent Annual Information Form and in the most recent Management Discussion and Analysis filed on SEDAR, which also provide additional general assumptions in connection with these statements. Osisko cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail. Osisko believes that the expectations reflected in those forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in this press release should not be unduly relied upon. These statements speak only as of the date of this press release.
