winter weather in the first three months of 2015, causing
the mill to operate only 78 percent of the time. That lower
operating time led to 105,572 ounces of gold produce for
the first quarter.
But the conveyor belt problems were resolved by
mid-February, according to the report, and the processing plant soon returned to design capacity. In the second
quarter, production rose to 125,348 ounces of gold - a 6.8
percent increase from the second quarter of 2014.
The company continues to improve its milling
capacity and mining rates. By the end of 2014, the
average mill throughput rate reached 54,310 tons per
day (tpd) and a mining rate of 234 tpd, according to
Detour Gold's year-end report. Refining its equipment
and finding new efficiencies have further increased
activity. The processing plant has been operating at its
design capacity of 55,000 tpd since March 2015 and
milling rates reached 2,712 tons per operating hour
(tpoh) in the second quarter of 2015 - well beyond the
design rate of 2,500 tpoh, according to Detour Gold's
quarterly reports.

"Our team is excited about our

forward to unlocking the potential of
our prospective large land package."
the mineral system and six of them returned significant gold mineralization. "The opportunity to identify and define a high-grade gold target is extremely
valuable to us," President and CEO Paul Martin said
in a statement. "With the success obtained from this
drilling program, we now plan to initiate a much larger
in-fill drilling campaign on Zone 58N to better define
the grade continuity of this mineralized system. Our
team is excited about our exploration successes and
looks forward to unlocking the potential of our prospective large land package."
Further exploration began this summer with a $5 million program to use three drill rigs to drill about 50 holes
totaling 30,000 meters. Detour Gold expects the program
will be sufficient to determine the underground gold
potential of the area. EMI

SEEKING NEW DEPOSITS
By the end of 2014, Detour Gold had 14.9 million ounces
in gold reserves, giving it the largest gold reserve among
producing Canadian goldmines, according to the company's website. But the ore-rich area of Ontario has other
lucrative veins waiting to be discovered.
The company is still evaluating a deposit located less
than a kilometer northwest of the Detour Lake mine. The
deposit, called Block A, has undergone 160,000 meters of
drilling tests since 2012, according to Detour Gold, and
has an estimated resource of 2 million ounces of gold.
On its own, the Block A vein would likely not justify
expansion, the company says, but it could be developed
alongside the Detour Lake mine to improve production
without significant investment. The evaluation of Block
A is being conducted in conjunction with the review of
the life of mine plan for Detour Lake, which should be
completed by the end of the year, Detour Gold says.
Other surrounding deposits hold more potential than
Block A. Last year, the company completed 14,874 meters
of drilling in 40 holes about six kilometers south of the
existing Detour Lake gold mine. Through those efforts,
it identified a promising mineralization system in the
area, called Zone 58N. To explore Zone 58N, Detour Gold
allocated $2 million for a limited drilling program to test
the depth extension of the system.
Testing began in January and crews drilled eight
holes totaling 5,700 meters. All eight holes intersected
