Detour Gold Provides Operational Update for Detour Lake Mine Tour on June 7

June 6, 2016

VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 6, 2016) - Detour Gold Corporation (TSX:DGC) ("Detour Gold" or the "Company") is pleased to provide an operational update at its flagship Detour Lake gold mine prior to its analyst and investor site visit on June 7, 2016.

Processing Plant (with new 410-conveyor)

The Company successfully installed and commissioned a new 410-conveyor system in the first half of April (refer to April 27, 2016 news release). The new system is proving more efficient and has been tested up to 4,600 tpoh versus the prior system's maximum rate of 3,800 tpoh. The tonnage shortfall resulting from the April shutdown (9 days) is expected to be recovered in the second quarter. The Company will also continue with additional adjustments to test its upper limit of 5,000 tpoh.

Pierre Beaudoin, Chief Operating Officer, added, "The constraint on the 410-conveyor system has now largely been lifted and the processing plant is performing at higher milling rates. In May, the plant recorded an impressive 2.0 Mt of ore processed, and while it is too early to confirm these rates for the long term, it is nevertheless a positive indication that we are on the right path to reach our target of processing 23 Mt of ore annually prior to 2019."

Following the planned shutdown, from April 21 to May 31, the processing plant has averaged a throughput of 64,462 tpd, including 13 days at above 70,000 tpd.

In the short term, in the event that the processing plant outperforms the mine output, the Company plans to supplement the plant with its large run-of-mine (ROM) medium grade stockpile, currently sitting at approximately 134,000 ounces (6.6 Mt at 0.63 g/t Au).

The gold production for the second quarter is forecast to be at the mid-point of our quarterly range guidance of 125,000 to 150,000 ounces.

Medium Grade Fines Test Underway

In parallel, the Company is currently running a test of 100,000 tonnes to enhance the grade by screening the fines (at minus 2") from the ROM medium grade stockpile (mentioned above). This test is expected to validate prior survey results where the grade was enhanced by approximately 100% with 30% of the mass. Final results, including productivity and operating costs, are expected in the third quarter. Subject to positive results, the Company may elect to screen and process the medium grade ore immediately (either from the existing ROM stockpiles or from direct feed).

Mine Output

For the second quarter to date, mining rates (Phase 1 and 2) are averaging 232,000 tpd, as the mine progresses through the pioneering part of Phase 2 and around the Campbell pit area. With the transfer of a rope shovel (CAT7495) into waste mining in June, the Company is targeting mining rates of between 250,000 and 270,000 tpd for the second half of 2016.

Lower Detour Drilling Program

The assay results from the 2016 winter drilling program at Lower Detour are expected to be released in July. The drilling program is expected to resume this summer to complete the remaining 25,000 metres of infill drilling at Lower Detour and other targets on the property.


Detour Gold reiterates its 2016 guidance of between 540,000 and 590,000 ounces of gold at total cash costs of US$675 to $750 per ounce sold and all-in sustaining costs of US$840 to US$940 per ounce sold (see end of news release for non-IFRS measures).

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.

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

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.
