“We are pleased to report a record quarter. Operationally, the mine and mill exceeded our expectations as reflected by the significantly higher production and lower costs reported this quarter,” said Paul Martin, President and CEO. “We expect to continue on this trend and finish the year on a strong note with higher gold production and lower costs in the second half of the year aided by a weaker Canadian dollar.”

Q2 2015 Summary Operational Results

• Gold production totaled 125,348 ounces, approximately 9% above the mid-point of the guidance range for the second quarter of 2015.

• For the quarter, the mill facility processed a record 5.2 million tonnes (Mt) of ore or an average of 57,015 tonnes per day (tpd) at recoveries of 91%. Processed grade was 0.82 grams per tonne (g/t), slightly higher than projections for the quarter.

• Mill operating time at 88% was in line with projections with a four day planned shutdown in June to replace SAG and ball mill liners on both lines, complete further improvements on the 410 conveyor system, and conduct a number of annual inspections which included the thickeners.

• Milling rates attained 2,712 tonnes per operating hour (tpoh) for the second quarter, exceeding the budget rate of 2,600 tpoh and the design rate of 2,500 tpoh. The processing plant has now been operating at design capacity of 55,000 tpd since March 2015.

• A total of 25.5 Mt (ore and waste) was mined in the second quarter (equivalent to mining rates of 280,000 tpd for Phase 1 and 2), approximately 18% higher than the annual budgeted rate of 238,000 tpd and above the fourth quarter target of 268,000 tpd.

• Phase 2 pre-stripping totalled 1.4 Mt for the quarter.

• At the end of the quarter, run-of-mine stockpiles had been successfully re-built to 1.7 Mt grading 0.71 g/t, providing operational flexibility for the second half of 2015.

• Total cash costs for the second quarter of 2015 were $734 per ounce sold⁽¹⁾ and all-in sustaining costs were $1,030 per ounce sold⁽¹⁾, lower than plan due to higher production and a favorable exchange rate.

• Lower unit costs were achieved in the second quarter, mainly due to more tonnes mined and milled. In addition, plant operating costs benefited from consumables (i.e. grinding media, cyanide, and SO₂) declining to their lowest levels since production commenced.

Note: mill availability is defined as mill operating time.

• For the remainder of 2015, the Company is targeting mining rates ranging between 250,000 and 290,000 tpd. Mine development will be focusing on opening the eastern part of the pit, delivering material to the tailings area using the mine haulage fleet, and maximizing feed grade by further reducing mining dilution. Access to the higher grade ore is now anticipated to start in the third quarter versus the fourth quarter and as a result approximately 10,000 to 15,000 ounces from the fourth quarter production is targeted to be processed in the third quarter.
• A second test of processing fines (enriched portion of the low-grade stockpile, referred to as mineralized waste grading an average of 0.44 g/t gold in the February 2014 life of mine plan) started on July 1 at a rate of up to 4,000 tpd. The test is scheduled to continue throughout the third quarter.

Note: Totals may not add up due to rounding.

Q2 2015 Financial Performance

• Metal sales for the second quarter were $147.5 million. The Company sold 123,296 ounces of gold at an average realized price of $1,215 per ounce⁽¹⁾, higher than the average London PM fix gold price of $1,192 per ounce due to the Company’s gold hedging program.

• Cost of sales for the first quarter was $140.0 million, including $39.8 million of depreciation and depletion expense, or $323 per ounce sold.

• The Company recorded a net loss of $15.4 million ($0.09 per share) in the second quarter.

The Company has no amount drawn under the revolving facility of Cdn$85 million and Cdn$42.6 million drawn under the Cdn$50 million letter of credit facility.

• Production costs in the second quarter of 2015 include an unfavourable adjustment to the Company’s electricity rebate related to electricity usage from January 2013 to April 2015. The adjustment resulted in an additional cost of $12.5 million, of which $9.7 million was recorded in current period production costs, and $2.8 million related to pre-commercial production period and charged to property, plant and equipment. The portion of the adjustment relating to 2015 usage amounted to $2.0 million. The balance is payable in 20 equal monthly instalments commencing in the third quarter of 2015.

About Detour Gold

Detour Gold is an intermediate gold producer in Canada that holds a 100% interest in the Detour Lake mine, a long life large-scale open pit operation.

Non-IFRS Financial Performance Measures

The Company has included certain non-IFRS measures in this news release. 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.

To improve comparability, total cash costs, all-in sustaining costs, average realized margin, adjusted net earnings (loss) and adjusted net earnings (loss) per share were revised, based on allocating the electricity adjustment into the appropriate historical period to which the cost applied (refer to the Second Quarter 2015 MD&A under the section “Revised non-IFRS measures: Electricity adjustment”. The Company believes this adjustment will result in a more meaningful trend analysis for investors and analysts to evaluate the Company’s performance. Additional details on the adjustment are included in the Second Quarter 2015 MD&A under “Cost of Sales”.

The non-IFRS measures are defined below and are reconciled with the reported IFRS measures. Refer to the Company’s Second Quarter 2015 MD&A for full details. The tables below are in thousands of dollars, except where noted.

Total cash costs

Detour Gold reports total cash costs on a sales basis. Total cash costs include production costs such as mining, processing, refining and site administration, agreements with Aboriginal communities, less non-cash share-based compensation and net of silver sales divided by gold ounces sold to arrive at total cash costs per gold ounce sold. The measure also includes other mine related costs incurred such as mine standby costs and current inventory write downs. Production costs are exclusive of depreciation and depletion. Production costs include the costs associated with providing the royalty in kind ounces.

All-in sustaining costs

Commencing in 2015, the Company adopted all-in sustaining costs on a prospective basis.

The Company believes this measure more fully defines the total costs associated with producing gold. The Company calculates all-in sustaining costs as the sum of total cash costs (as described above), share-based compensation, corporate general and administrative expense, exploration and evaluation expenses that are sustaining in nature, reclamation cost accretion (also known as unwinding of the discount on decommissioning and restoration provisions), sustaining capital including deferred stripping, and realized gains and losses on hedges due to operating and capital costs, all divided by the total gold ounces sold to arrive at a per ounce figure.

Other companies may calculate this measure differently as a result of differences in underlying principles and policies applied. Differences may also arise to a different definition of sustaining versus non-sustaining capital.

Average realized price and Average realized margin

Average realized price is calculated as metal sales per the statement of comprehensive loss and includes realized gains and losses on gold forwards, less silver sales. Average realized margin represents average realized price per gold ounce sold less total cash costs per ounce sold.

Adjusted net earnings (loss) and Adjusted basic net earnings (loss) per share

Adjusted net earnings (loss) and adjusted basic earnings (loss) per share are used by management and investors to measure the underlying operating performance of the Company. Presenting these measures from period to period helps management and investors evaluate earnings trends more readily in comparison with results from prior periods.

Adjusted net earnings (loss) is defined as net earnings (loss) adjusted to exclude specific items that are significant, but not reflective of the underlying operations of the Company, including: fair value change of the convertible notes, the impact of foreign exchange gains and losses, including the foreign exchange on deferred income and mining taxes, non-cash unrealized gains and losses on derivative instruments, accretion on convertible notes, unwinding of discount on decommissioning and restoration provisions, impairment provisions and reversals thereof, and other non-recurring items. In addition, adjusted net earnings (loss) excludes the impact of the electricity rebate related to prior periods electricity usage as described in MD&A for Q2 2015 “Second Quarter 2015 Financial Results – Cost of Sales” section. Adjusted basic net earnings (loss) per share is calculated using the weighted average number of shares outstanding under the basic method of loss per share as determined under IFRS.

The Company has included the additional IFRS measure “Earnings (loss) from mine operations” in this press release. Management noted that “Earnings (loss) from mine operations” provides useful information to investors as an indication of the Company’s principal business activities before consideration of how those activities are financed, sustaining capital expenditures, corporate administration expense, exploration and evaluation expenses, loss on disposal of assets, finance income and costs, and taxation.
