During the second quarter of 2017, Kumtor produced 138,623 ounces of gold compared to 97,724 ounces of gold in the comparative period of 2016.

During the second quarter of 2017, Kumtor’s average mill head grade was 3.53 g/t with a recovery of 79.3%, compared to 2.63 g/t and a recovery of 71.9% for the same period of 2016.

Commentary

Scott Perry, CEO of Centerra Gold stated, «During the second quarter we continued to deploy our

Company-wide safety leadership program «Work Safe, Home Safe» to all our sites, but as we reported on in the first quarter report this was over shadowed by a fatality in early April at Kumtor.

With our second quarter earnings release today, the Company increased its gold production guidance for Kumtor for the year to 525,000 — 555,000 ounces. We also lowered our expected all-in sustaining cost⁴ guidance at Kumtor to $751 to $795 per ounce sold. We are well positioned to achieve our revised gold production and cost guidance for the year, ranking the Company in the bottom quartile on the global gold producers All-In Sustaining Cost curve.»
