Osisko’s Canadian Malartic pours first gold

QUEBEC - On April 13, 2011, Osisko Mining Corp. of Montreal announced the first gold pour from its flagship Canadian Malartic mine 25 km west of Val d'Or. The project involved spending roughly $760 million, moving the entire town of Malartic, and developing a bulk tonnage open pit and a 55,000-t/d mill. The mill is expected to reach commercial production - 650,600 oz of gold annually - next month.

Sean Roosen, Osisko president and CEO, commented, "We are extremely pleased to achieve our first gold production at Canadian Malartic, after only six years from drilling our first hole on the property. Commissioning has gone very smoothly, and we are well on track to achieve commercial production by the end of May.

"This achievement is a direct result of the outstanding efforts from Osisko's management team and employees, our contractors, suppliers, the residents of Malartic and officials from the government of Quebec. We also express our gratitude to our shareholders, bankers and lenders who have supported our vision of building a world class gold mining operation," he added.
