Results from drill hole BA08-3219 are particularly interesting as this mineralized intersection is the downward extension (to a vertical depth of 340 to 420 metres) of the high grade intersection previously reported in drill hole BA08-3002 (7.61 g/t Au over 57 metres). These two holes intersected mineralization located between old underground workings of the East Malartic mine, along section 855E. The true width of the mineralized zone along this section is 22 to 40 metres.
Drill holes BA08-3220, BA08-3228, BA08-3229, BA08-3230, BA08-3232B, BA08-3234 and BA08-3250H were lost in fault zones or intercepted historic mine workings and did not reach the intended target depths. Drill holes BA08-3217, BA08-3218, BA08-3239, BA08-3240 and BA08-3241 and BA08-3249 did not reach the intended target depths and did not intersect significant mineralization. Assay results for further holes at South Barnat are pending.
The definition drill program is focused on an 850 metre-long grid oriented northwest-southeast with drill sections spaced 25 metres apart. All holes on this grid are inclined 45 to 75 degrees to the northeast or southwest. True widths of the mineralized intersections reported above are 40 to 70 percent of the drilled intersections.
Drilling to date suggests that the minimum strike length of the South Barnat Zone is 850 metres with an average true width between 30 and 120 metres. The mineralized zone is open along strike to the east, where it merges with the old East Malartic Mine and where recent drilling has indicated a possible extension over an additional 360 metres (see January 13, 2008 press release). South Barnat extends to depths of 250 to 400 metres in the southeastern portion, where the system is still open at depth. Estimated depth in the northwestern third of the deposit is 130 to 200 metres.
Mineralization in the South Barnat Zone is located to the north and south of the old Barnat and East Malartic mine workings, along the southern edge of the Cadillac fault. The disseminated gold mineralization comprises multiple subvertical, tabular subzones hosted in silicified greywackes of the Pontiac Group south of the fault contact. North of the fault, mineralization is hosted in both porphyry dykes and schistose, carbonated and biotitic ultramafic rocks north. Porphyry dykes also host late quartz veins containing visible gold.
All NQ or HQ core assays reported above were obtained by standard 50 g fire assaying-AA finish or gravimetric finish at ALS Chemex laboratories in Val d'Or, Quebec. Reported weighted averages were calculated using a minimum of 0.50 g/t Au over successive maximum intervals of 20 metres with no upper cut-off of individual assays. Intersected drifts or lost core within mineralized intersections were incorporated as blank intervals.
Osisko Mining Corp. is currently developing the Canadian Malartic gold deposit and adjacent mineralized zones into a large-scale open pit, bulk-tonnage mining operation. The Company is well-funded and is carrying out an aggressive definition drilling and exploration campaign. Eight drills are currently working on the property, with five dedicated to completing the 130,000 metre infill drilling on the South Barnat Zone by mid-February.
A NI 43-101 compliant, 6.3 million ounce gold Reserve estimate and Feasibility Study on the main Canadian Malartic gold deposit was released on November 25, 2008 and has been filed on SEDAR. This estimate does not include the South Barnat Zone or any other mineralized zone located outside the main deposit that is currently being evaluated by Osisko.

Although the Corporation believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, including, without limitation that all technical, economical and financial conditions will be met in order to put the Canadian Malartic Project into commercial production, 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 mill production personnel, results of exploration and development activities, the Corporation's limited experience with production and development stage mining operations, uninsured risks, regulatory 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 the Corporation's most recent Annual Information Form filed on SEDAR, which also provides additional general assumptions in connection with these statements. The Corporation cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on the Corporation's forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail.
