Q3 2013 Selected Operational and Financial Information

During the third quarter of 2013, revenues were $100.5 million from gold sales of 75,600 ounces. With commercial production at Detour Lake mine declared on September 1, $67.4 million was credited against capitalized project costs.

During the commercial production period (30 days in September), total cash costs per ounce of gold³ sold were $1,214. Cash operating costs per tonne⁵ averaged Cdn$22.48/t milled: mining costs of Cdn$2.39/t mined; processing costs of Cdn$11.38/t milled; and G&A of Cdn$2.98/t.

At this stage of the ramp-up of the Detour Lake mine, these costs are reasonable as the operation has not yet reached throughput design capacity of 55,000 tpd. Operating costs are expected to gradually decrease as the Company continues to improve the efficiency of the operation.

Cash and cash equivalents were $156 million at September 30, 2013. The Company has completed Cdn$136 million of its Cdn$192 million capital spending on mine development and sustaining expenditures for 2013.

¹ Gold ounces sold exclude 2% royalty paid in-kind. During the three and nine months ended September 30, 2013, the Company accrued or paid in-kind 1,600 and 2,631 ounces of gold.

² All sales prior to commercial production (September 1, 2013) were credited against capitalized project costs.

³ Refer to the section on Non-IFRS Financial Performance Measures at end of the press release. Reconciliation of these measures is described in the MD&A on page 10.

⁴ Total cash costs are calculated on post-commercial ounces sold only (24,700 ounces).

⁵ These costs are furnished to provide additional information and will not reconcile to production costs mentioned in the Income Statement (and the table above).

Detour Lake Mine - October Preliminary Operational Results and Update

During the month of October, 29,541 ounces of gold were produced (32,043 ounces poured). The mill processed a total of 1.4 million tonnes (Mt) of ore at an average grade of 0.72 g/t. Metallurgical recoveries averaged 91.6%, higher than projected levels in the feasibility study.

Throughput rates continued to improve and averaged 45,000 tpd during the month, with 15 days above 50,000 tpd. Mill availability reached 83% during the month.

Mining rates averaged 205,000 tpd in October. Mining of the higher grade Domain #2 started this week and is expected to represent approximately 20% of the total feed for the fourth quarter.

On October 18, 2013, the Company and North America Construction (1993) Ltd. (NAC) settled the litigation that had been ongoing since 2012 for Cdn$24.3 million (Cdn$19.3 million of which has been paid with future payments of Cdn$2.5 million payable on each of June 30, 2014 and June 30, 2015). The Company had accrued Cdn$21 million for the NAC claims. It is anticipated that the liens (Cdn$66.5 million, including HST) registered by NAC will be removed from title in November 2013.

Updated Outlook

The Company continues to anticipate that the fourth quarter of 2013 will be the highest production quarter of the year. The Company does not believe that it will attain its prior 2013 guidance production target of approximately 270,000 ounces and now expects production of between 240,000 and 260,000 ounces of gold. Total cash costs for the commercial production period (September 1 to year-end) are expected to remain within the Company's previously stated guidance of $1,100 per ounce.

In 2014, the Company will continue to optimize the operation to reach nameplate capacity of 55,000 tpd by year-end. Preparation of the 2014 budget is well underway. Preliminary numbers indicate 2014 production of between 440,000 and 500,000 ounces of gold at all-in sustaining costs of $1,150 to $1,250 per ounce. The Company will provide 2014 guidance (including projected costs, production, grades and other parameters) in January 2014.

In the first quarter of 2014, the Company also plans to report an updated mine plan for Detour Lake, which will include year-end 2013 mineral reserves and resources. The mineral reserves will be estimated at a gold price of US$1,000 per ounce using a cut-off grade of 0.5 g/t gold (unchanged from prior estimate). The decision to proceed with an expansion of the processing plant (55,000 to 61,000 tpd) is expected to be taken at year-end 2014.

Non-IFRS Financial Performance Measures

The Company has included certain non-IFRS measures in this press release, including "total cash cost per gold ounce" and "average realized price and average realized margin". The Company believes that these measures, in addition to conventional measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company. The non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers.
