NEWS RELEASE

Centerra Gold 2016 Year-End Gold Mineral Reserves

Increase to 16 Million Contained Ounces

This news release contains forward-looking information that is subject to the risk factors and assumptions set out on

page 8 and in our Cautionary Note Regarding Forward-l ooking Information on page 11 . At Mount Milligan mineral

reserves and mineral resources are presented on a 100% basis. Sales of gold and copper from the Mount Milligan mine

fall under a streaming arrangement whereby Royal Gold Inc. is entitled to 35% an d 18.75% of gold and copper sales,

respectively. All figures are in United States dollars.

Toronto, Canada, February 23, 2017: Centerra Gold Inc. (TSX: CG) today issued its 2016 year-end

estimates for mineral reserves and mineral resources.

Highlights:

 Centerra’s proven and probable gold mineral reserves increased to 16 million ounces of contained

gold (673.4 million tonnes (Mt) at 0.7 g/t gold) from 8.4 million contained ounces (112.5 Mt at 2.3 g/t

gold) a year ago.

 At Centerra’s 100% owned Mount Milligan mine in north central British Columbia, Canada, proven

and probable mineral reserves are estimated to be 5.8 million ounces of contained gold and 2,049

million pounds of contained copper (496.2 Mt at 0. 4 g/t gold and 0.187% copper at an NSR cut-off of

$8.12 per tonne). The Company plans to complete and file a new NI 43-101 technical report on the

Mount Milligan mine by the end of March 2017.

 At Centerra’s 50% owned Greenstone Gold Project in Canada, the Company announced the

completion of the feasibility study for the Hardrock Project in November 2016. As a result of this

study, measured and indicated mineral resources on the Hardrock open pit were upgraded to an

estimated probable mineral reserve of 70.9 milli on tonnes at 1.0 g/t gold containing 2.3 million

ounces of gold (Centerra’s 50% share) at a cut-off grade of 0.33 g/t gold.

Scott Perry, CEO of Centerra Gold said: “In 2016, with the acquisition of Thompson Creek Metals Company

Inc. and adding the Mount Milligan mine to our operati ng platform we have significantly added to our gold

mineral reserves and now for the first time include c opper mineral reserves. At the Company’s 50% owned

Greenstone Gold Property, in Canada, the mineral res ources were successfully converted to mineral reserves

with the bankable feasibility study on the Hardrock Project released in November, which also contributed to

the increase in our total gold mineral reserves to an estimated 16 million ounces of contained gold.”

Year-end Gold Mineral Reserves and Mineral Resources

Mineral Reserves

At the end of 2016, Centerra’s estimated proven and probable gold mineral reserves increased by 7.6 million

contained ounces, after accounting for processing of 696, 000 contained ounces in 2016. Centerra’s proven

and probable mineral reserves now total an estimated 16.0 million ounces of contained gold (673.4 Mt at 0.7

g/t gold), compared to 8.4 million contained ounces (112.5 Mt at 2.3 g/t gold) as of December 31, 2015. The

mineral reserve increase is primarily a result of the addition of Mount Milligan mineral reserves after the

Company closed the acquisition of Thompson Creek Metals Company Inc. on October 20, 2016 and the

completion of the feasibility study on the Hardrock Project where mineral resources were upgraded to mineral

reserves in November 2016. The 2016 year-end mineral re serves have been verified and estimated using a

gold price of $1,200 per ounce.

At the Kumtor mine, in the Kyrgyz Republic, proven and probable gold mineral reserves decreased by

511,000 contained ounces, after accounting for processi ng of 696,000 contained ounces in 2016. In 2016

mineral reserves decreased primarily due to mining depl etion and, as a result Kumtor’s proven and probable

mineral reserves now total an estimated 5.1 million ounces of contained gold (63.1 Mt at 2.5 g/t gold) at the

end of December 2016, compared to 5.6 million contained ounces (69.2 Mt at 2.5 g/t gold) as of December

31, 2015.

In Canada, at the Mount Milligan mine, proven and pr obable mineral reserves to tal 5.8 million ounces of

contained gold (496.2 Mt at 0.4 g/t gold) at the end of December 2016. With the completion of the feasibility

study for the Hardrock Project at the Company’s 50% owned Greenstone Gold Project measured and

indicated mineral resources on the Hardrock open pit we re upgraded to an estimated probable mineral reserve

of 2.3 million ounces of contained gold (70.9 Mt at 1.0 g/t gold) (Centerra’s 50% share).

In Mongolia, at the Gatsuurt Project proven and pr obable mineral reserves are unchanged from 2015 and are

estimated to be 1.6 million contained ounces of gold (17.1 Mt at 2.9 g/t gold).

In Turkey, at the Öksüt Project, the proven and pr obable mineral reserves are unchanged from 2015 summary

and contain an estimated 1.2 million ounces of gold (26.1 Mt at 1.4 g/t gold).

Mineral Resources

As of December 31, 2016, Centerra’s measured and in dicated gold mineral resources, net of gold mineral

reserves, increased by 3.2 million contained ounces to an estimated total of 7.4 million ounces of contained

gold (330.0 Mt at 0.7 g/t gold) compared to the December 31, 2015 estimate. The change is primarily a result

of the acquisition of Mount Milligan which added 1.8 million contained ounces of gold and the addition of

1.4 million contained ounces of gold (Centerra’s 50% share) at the Greenstone Gold Property.

The 2016 year-end mineral resource estimates for the Ök süt Project in Turkey, Boroo, Gatsuurt, ATO and

Ulaan Bulag properties in Mongolia are unchanged from 2015 year-end estimates.

On January 31, 2017, Centerra Gold’s Mongolian subs idiary, Centerra Gold Mongolia (CGM) entered into

definitive agreements to sell the ATO Project, located in Eastern Mongolia, to Steppe Gold LLC and Steppe

Gold Limited for gross proceed of $19,800,000. CGM has received $800,000 upon signing of the definitive

agreements and is expected to r eceive $9,000,000 at closing, which is scheduled to occur in the second

quarter of 2017, followed by tw o additional $5 million cash payments at the first anniversary and second

anniversary date of the closing of the transaction. The closing of the transaction is conditional upon Steppe

Gold Limited executing their financing plans which th e Company understands is scheduled to be completed

in mid-2017.

As of December 31, 2016, Centerra ’s inferred gold mineral resource estimate totals 5.8 million contained

ounces of gold (57.9 Mt at 3.1 g/t gold), an increase of 3.2 million contained ounces from December 31,

2015. At Kumtor 3.4 million ounces of gold (14.5 Mt at 7.3 g/t gold) are contained within the estimated

underground inferred mineral resources in the SB, Saddle a nd Stockwork Zones. This increase of 1.7 million

contained ounces in the 2016 year-end inferred underg round mineral resource estimate is due to a

reinterpretation of mineralized structures and their along strike and down dip extents. Additionally, a lower

cut-off grade of 4.9 g/t gold was used at 2016 year-end compared to 6.0 g/t gold cut-off used for estimation at

December 31, 2015. In addition 1.4 million contai ned ounces (Centerra’s 50% share) of open pit and

underground inferred gold mineral resources were added to the inferred mineral resource category at the

Greenstone Gold Property in 2016.

Year-end Copper Mineral Reserves and Mineral Resources

Mineral Reserves

At the end of 2016, Centerra’s proven and probable copper mineral reserves total an estimated 2,049 million

pounds of contained copper (496.2 Mt at 0.187% copper). The copper mineral reserves are located at the

Company’s Mount Milligan mine which was acquired with the acquisition of Thompson Creek Metals

Company Inc. on October 20, 2016. The copper mine ral reserves have been estimated based on a copper

price of $2.95 per pound and an NSR cut-off of $8.12 pe r tonne, which takes into consideration metallurgical

recoveries, concentrate grades, transportation costs, smelter treatment charges and royalty and streaming

arrangements in determining economic viability.

Mineral Resources

As of December 31, 2016, Centerra’s measured and indicated copper mineral resources, net of mineral

reserves, total an estimated 4,076 million pounds of contained copper (749.9 Mt at 0.242% copper). The

copper mineral resources are located at the Mount Milligan mine and the Berg Property, located in Canada.

At Mount Milligan, in British Columbia, Canada, measured and indicated mineral resources total an estimated

718 million pounds of contained copper ( 243.9 Mt at 0.133% copper) at th e end of December 2016 and have

been estimated based on a copper price of $3.50 per poun d. The open pit mineral resources are constrained

by a pit shell and are estimated based on an NSR cut-o ff of $8.12 per tonne, which takes into consideration

metallurgical recoveries, concentrate grades, transporta tion costs, smelter treatment charges and royalty and

streaming arrangements in determining economic viability.

At the Berg Property, in British Columbia, Canada, measured and indicated mineral resources total an

estimated 3,359 million pounds of contained copper (506.0 Mt at 0.301% copper) at the end of December

2016 and have been estimated based on a copper pri ce of $1.60 per pound. Th e unconstrained open pit

mineral resources have been estimated based on a 0.30% copper equivalent cut-off grade to a maximum depth

of 450 metres below surface.

As of December 31, 2016, Ce nterra’s inferred copper mineral resource estimate to tals 764 million pounds of

contained copper (155.6 Mt at 0.218% copper). This includes at Mount Milligan an estimated 31 million

pounds of contained copper (11.0 Mt at 0.125% copper) and at the Be rg Property an estimated 733 million

pounds of contained copper (144.6 Mt at 0.230% copper).

 a gold price of $1,200 per ounce, except at Hardrock which used $1,250 per ounce

 a copper price of $2.95 per pound

 exchange rates:

o $1USD:0.95 Euro

The assumed diesel price of $0.55/litre at Kumtor assume s that no Russian export duty will be paid on the

fuel exports from Russia to the Kyrgyz Republic. Di esel fuel is sourced from sep arate Russian suppliers and

only loosely correlates with world oil prices. The diesel fuel price assumptions were made when the price of

oil was approximately $50 per barrel. Crude oil is a component of diesel fuel purchased by the Company,

such that changes in the price of Brent crude o il generally impacts diesel fuel prices. The Company

established a hedging strategy to manage changes in diesel fuel prices on the cost of operations at the Kumtor

mine. The diesel fuel hedging program is a 24-month rolling program. The Company targets to hedge up to
