Throughput and production at Canadian Malartic are progressing well. An overall mine production increase of 15% was achieved during the quarter compared to the last quarter of 2012 despite increased maintenance of the loading equipment and reduced availability in February and March. Approximately 15.9 million tonnes of ore and waste (176,305 tonnes/day) and 1.8 million tonnes of overburden were moved during the first quarter of 2013, compared to 13.9 million tonnes of ore and waste (152,757 tonnes/day) and 2.0 million tonnes of overburden during the first quarter of 2012.

On February 13, 2013, the Québec Government approved a new decree which modified the operating parameters of the Canadian Malartic mine. The changes included extending the duration of blasts, increasing the time period during which blasts can be executed, and providing greater access to the northern part of the deposit. The modified parameters will provide greater flexibility in day-to-day operations.

During the quarter, approximately 1,510 equipment hours (1.7% of available hours) were lost due to noise and weather constraints.

Operating Costs

Cash costs per ounce(6) for the first quarter of 2013 stood at $804 compared to $821 in the first quarter of 2012. The improvement over the comparative period in 2012 is mainly the result of increased throughput and gold production, improved efficiencies and reduction in contractors' costs.

Following the issuance of a new IFRS accounting pronouncement with respect to stripping costs in the production phase of a surface mine, the Company adopted the new standard effective January 1, 2013. In accordance with the required practice, Osisko restated its prior periods which had the positive impact of increasing mine operating earnings in prior quarters of 2012.

It is anticipated that as the operations at Canadian Malartic stabilize and that the operations are further optimized, the operating costs will continue their downward trend.

Earnings

Excluding specific non-cash items, adjusted net earnings(7) amounted to $36.4 million ($0.08 per share) in 2013 compared to $59.6 million ($0.15 per share) in 2012.

(In thousands of dollars except for amounts per share) Three Months Ended

Deferred Income and Mining Tax Expense 13,265 23,937
Adjusted Net Earnings 36,426 59,573
Adjusted Net Earnings per Share 0.08 0.15

The decrease in net earnings is mainly the result of higher mine operating costs for products sold, higher depreciation and exploration expense.

Investments

The Company invested $65.7 million in property, plant and equipment during the first quarter. These investments were mainly focused on the development of the Canadian Malartic mine.

Recent volatility in the gold price and financial markets has led Osisko to review its rate of discretionary spending in exploration and advancing new projects. As a result, the Company will be decreasing discretionary spending for 2013 by over $80 million.

Upper Beaver Project and Kirkland Lake - Larder Camp

On December 28, 2012, Osisko completed the acquisition of Queenston Mining Inc. As part of the transaction, the Company acquired the Upper Beaver Project and a package of lands covering 230 km2 in the rich Kirkland Lake Gold Camp, which has produced over 40 million ounces in past years. Queenston Mining Inc. changed its name to Osisko Mining Ltd. on January 16, 2013.

The Upper Beaver Project has the following resources as calculated by SRK Consulting, on November 5, 2012.

The work at Upper Beaver is focused on drilling deep holes to test extensions of known zones. The Company has completed approximately 29,290 meters of drilling since January 1, 2013. Over the next few months, work will be limited to completion of current holes and compiling information generated during the drilling phase to date.

(7) Reconciliation of non-IFRS measures is provided under Note Regarding Certain Non-IFRS Measures of Performance of this press release.

The shaft collar work has recently been completed. Construction of the head frame and surface facilities will be delayed, as well as the shaft sinking. Osisko project personnel are reviewing opportunities to capture savings due to the recent slowdown in the mining sector. This reassessment period will result in a deferral of approximately $50 million of the planned Upper Beaver outlays of $70 million for 2013.

The Queenston transaction also provides the Company with a major foothold in a prolific gold camp that has produced in excess of 40 million ounces. Queenston had consolidated the land package over the past 20 years. To date, there have been several satellite deposits identified that could feed a regional mill.

The Company has completed 31,750 meters on various regional targets in the Kirkland Lake - Larder camp. Drilling activities will be reduced to focus on compilation and assessment of the results. Exploration expenditures at Kirkland Lake for 2013 are estimated at the original budget of $20.0 million.

Hammond Reef Gold Project

Osisko acquired the Hammond Reef gold project located near Atikokan in Northwestern Ontario, through the acquisition of publicly traded Brett Resources Inc. in mid 2010 for $375.0 million. Hammond Reef is a large and growing development project with potential to become a substantial open-pit mine. During the first quarter of 2013, Osisko invested $4.6 million for total of $153.7 million since its acquisition in 2010. In the first quarter of 2013, efforts were focused on the preparation of the feasibility study and the publication of the environmental assessment report.

A new resource estimate for Hammond Reef was released on January 28, 2013. New drilling by Osisko and Brett Resources from January 2010 to July 2011 (approximately 300,000 meters) significantly increased the size of the deposit. Additional drilling subsequent to July 2011 was performed to allow for the upgrade of the entire in-pit deposit to measured and indicated category early 2013. As per the estimate, global measured and indicated resources currently stand at 5.43 million ounces gold at an average grade of 0.86 g/t Au and the global inferred resource stands at 1.75 million ounces gold at an average grade of 0.72 g/t (based on 0.50 g/t Au lower cut-off).

With the completion of the drilling and metallurgical test work, the engineering and construction group intensified its activities on the feasibility phase. Initial studies were launched and a conceptual design and project parameters were established. The process design criteria have been fixed at 60,000 tonnes per day. A feasibility study report is expected to be completed in 2013.

For the Hammond Reef project, permitting is subject to both approvals from Federal (Canadian Environmental Assessment Agency) and Provincial (Ministry of the Environment, Environmental Approvals Branch) authorities.

  1. The Ontario Minister of Environment provided approval to the Final Amended Terms of Reference for the environmental approval on July 4, 2012 while the Federal Agency had finalized the Environmental Impact Statement Guidelines for the preparation of the Environmental Impact Statement in October of 2011;
  2. One (single) report will be prepared to meet both federal & provincial requirements;
  3. A draft Environmental Assessment / Environmental Impact Statement report was submitted on February 15, 2013. The five week comment period ended on April 5, 2013. Comments were received from Aboriginal groups, the public and the government review team and the Company is preparing its responses to the matters raised.

Osisko's engineering and construction group is reviewing various estimates in light of the recent changes in the marketplace and is seeking opportunities to reduce capital costs.

The level of expenditures at Hammond Reef is expected to be reduced by $3.0 million from the original 2013 budget of $10.0 million.

No decision will be made to advance the Hammond Reef project further pending receipt of the final feasibility which is expected later this year.

Exploration

The Company continues to pursue value creation through the discovery of new ore deposits. Osisko has several agreements and has staked properties in various gold camps within the Americas.

The Company has been active in the Guerrero District of Mexico where it has accumulated a large land package in an area with operating gold mines and advanced exploration projects.

Building on its flagship Canadian Malartic Mine, the Company hopes to discover and build new gold mines to ensure continued growth. These new projects will be developed only if they meet rate-of-return criteria and the Company has the financial capabilities to conduct such expansion. As per the Company's recent announcement, the budget for exploration will be significantly reduced through the rest of 2013.

Modifications to the Company's exploration and advanced projects will result in Osisko reducing its workforce by approximately 6% over the next few months.

Liquidity and Capital Resources

As at March 31, 2013, the Company's cash and cash equivalents, short-term investments and restricted cash amounted to $139.3 million compared to $155.5 million as at December 31, 2012, as summarized below:

(In thousands of dollars) March 31,
2013
December 31,

Cash and cash equivalents 100,358 93,229
Short-term investments - 19,357
Restricted cash
Current 558 4,563
Non-current 38,362 38,362
139,278 155,511

Short-term investments were acquired following the acquisition of Queenston as at December 28, 2012 and were converted to cash and cash equivalents during the first quarter of 2013 to increase the flexibility of available liquidities.

Outlook for 2013

Following the modifications and commissioning of the pre-crushing circuit and the second pebble crushing unit, it is anticipated that mill throughput should be stabilized in 2013. Gold production is estimated between 485,000 - 510,000 ounces for the year. As a result of gaining access to higher grade material in the second half of the year, it is anticipated that gold output will be higher in the second semester. Cash costs per ounce(8) are estimated between $780 and $825 per ounce, a 9% to 14% reduction in costs from 2012.

Recent volatility in the gold price and financial markets has led Osisko to review its rate of discretionary spending in exploration and advancing new projects. As a result, the Company will be decreasing discretionary spending for 2013 by over $80 million.

Following the issuance of a new IFRS accounting pronouncement with respect to stripping costs in the production phase of a surface mine, the Company expects to capitalize stripping costs for the remainder of 2013 (for Q1 2013, the amount capitalized was $7.4 million). Capitalized stripping costs are not reflected in the below table. The change in policy has no impact on cash and cash equivalents, however, cash costs per ounce(8) are expected to decrease by approximately $50 and capital expenditures are expected to increase by the same amount.

(8) Reconciliation of non-IFRS measures is provided under Non-IFRS Measures of Performance of this press release.

Capital expenditures for 2013 are now estimated at $138 million as follows:

(In millions of dollars) Revised budget(b) Original budget Reduction
Canadian Malartic mine 80.8 98.0 17.2
Upper Beaver project 18.5 70.0 51.5
Hammond Reef 7.0 10.0 3.0

Total 147.2 228.0 80.8
(a) Excludes write-off of projects in Q1 2013 for $2.0 million.
(b) Excluding variation in accounts payable related to the Canadian Malartic expansion, Hammond Reef, Upper Beaver and Kirkland Lake projects for $9.6 million in Q1 2013.
(c) Exploration - expensed through income statement is higher in revised budget compared to original budget, due to some investments in Mexico being expensed in Q1 2013 whereas for budget purposes the total investments were capitalized.

Outstanding Share Data

As of May 9, 2013, 436,669,709 common shares were issued and outstanding. A total of 19,061,259 common share options were outstanding to purchase common shares under the Company's share option plan and 14,517,453 common share purchase warrants were outstanding.

Modifications to the Mining Tax Regime in Québec

On May 6, 2013, the Quebec Government announced modifications to its mining tax regime. Under the new regime, which comes into effect on January 1, 2014, mine operators will be required to pay the greater of:

  1. Minimum tax of 1% on the first $80 million, and 4% thereafter on mine profit calculated prior to processing; and
  2. Mining tax based on profits of 16% of the first tranche of 35% of operating income, 22% on next tranche of 15%, and 28% on the remaining balance.

The modifications will ensure that the Government receives a minimum compensation from all mining activities, and shares in an increasing portion as the mine benefits from higher profitability levels.

Cautionary Notes Concerning Estimates of Mineral Resources

This news release uses the terms measured, indicated and inferred resources as a relative measure of the level of confidence in the resource estimate. Readers are cautioned that mineral resources are not economic mineral reserves and that the economic viability of resources that are not mineral reserves has not been demonstrated. In addition, inferred resources are considered too geologically speculative to have any economic considerations applied to them. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for Preliminary Assessment as defined under NI 43-101. Readers are cautioned not to assume that that further work will lead to mineral reserves that can be mined economically.

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, achieving greater flexibility in day-to-day operations as a result of the new decree, continued downward trend in operating costs as a result of stabilization and optimization of operations at Canadian Malartic, successful decreasing of discretionary spending by over $80 million in 2013 (including deferral of approximately $50 million of the planned Upper Beaver outlays of $70 million for 2013), the development of satellite deposits in the Kirkland Lake area, completion of the Hammond Reef project feasibility study in 2013, positive outcome of exploration work conducted in the Guerrero District of Mexico and elsewhere, successful reduction of Osisko's workforce by approximately 6% in a timely manner, and the successful stabilization and optimization of operations at Canadian Malartic and increase in gold output in the second semester of 2013. Although Osisko 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 achieve such events qualified by the foregoing cautionary note regarding forward looking statements, 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.

Note on restatement of 2012 balances

Balances related to 2012 have been restated to reflect the impact of the adoption of IFRIC 20, Stripping Costs in the Production Phase of a Surface Mine. IFRIC 20 provides guidance on the accounting for the costs of stripping activities during the production phase of surface mining when two benefits accrue to the entity as a result of the stripping: useable ore that can be used to produce inventory and improved access to further quantities of material that will be mined in the future periods. The Company adopted IFRIC 20 effective January 1, 2013. Upon adoption of IFRIC 20, the Company assessed the stripping asset on the balance sheet as at January 1, 2012 and determined that there are identifiable components of the ore body with which this stripping asset can be associated, and therefore no balance sheet adjustment was recorded at that date. The adoption of IFRIC 20 has resulted in increased capitalization of waste stripping costs and a reduction in mine operating costs in 2012. If the Company had not adopted IFRIC 20, the net earnings and capitalized waste stripping costs for the current and comparative periods would have decreased.

The impact of adopting IFRIC 20 on the 2012 balances is presented below:
