TORONTO, ONTARIO -- (Marketwire) -- 02/07/13 --


This news release contains forward-looking information that is subject to the risk factors and assumptions set out on page 12 and in our Cautionary Note Regarding Forward-looking Information on page 14. All figures are in United States dollars.


Centerra Gold Inc. (TSX:CG) today issued updated 2012 year-end estimates for the Company's reserves and resources and a fourth quarter 2012 exploration update. The updated reserves and resources are based on the new Kumtor KS-13 open pit mine expansion (announced November 7, 2012) and the Company's successful 2012 exploration programs.


Highlights (using $1,350/oz. gold price for reserve estimation):


--  At Centerra's 100% owned Oksut project in Turkey, a new resource
    estimate of 682,000 contained gold ounces of indicated resources and
    477,000 contained gold ounces of inferred resources has been outlined as
    a result of the successful drilling in 2012. 

--  Exploration drilling at the Kumtor project in 2012 has further increased
    both open pit and potential underground mineral resources below the KS-
    13 pit design. 

--  As a result of the KS-13 open pit expansion, first announced on November
    7th, 2012, the Kumtor proven and probable reserves (as of December 31,
    2012) have increased by 58% or 3.6 million contained ounces of gold
    compared to 6.3 million ounces of gold as of December 31, 2011 and now
    total 9.5 million contained ounces of gold. 



During 2012, Centerra's proven and probable gold reserves increased by 3.6 million contained ounces (before accounting for 2012 production) to 11.1 million ounces of contained gold, compared to 8.1 million ounces as of December 31, 2011. This represents an increase of 45% before accounting for 534,000 contained ounces processed at Kumtor and Boroo during 2012. The total reserve increase is the result of the significant expansion of the Kumtor Central Pit and is described in detail in a new NI 43-101 technical report filed on SEDAR in December 2012. All 2012 year-end reserves were estimated using a gold price of $1,350 per ounce compared to $1,200 per ounce at December 31, 2011.


In Mongolia, at the Boroo mine, proven and probable reserves total 178,000 contained ounces of gold after accounting for approximately 110,000 contained ounces being processed in the mill and or loaded on the heap leach pad in 2012. The remaining reserves are now entirely within existing ore stockpiles on surface. At the current reserve gold price assumption, the Boroo operation can continue to feed the mill from stockpiles for approximately two more years and operate and recover gold from the heap leach pad into 2014. At the Gatsuurt project, proven and probable reserves remain unchanged at 1.5 million ounces of contained gold.


The initial resource estimate for the 100% owned Oksut project in Turkey has an indicated resource of 682,000 ounces of contained gold and an inferred resource of 477,000 ounces of contained gold. The estimated resource is contained in two zones. The Ortacam North Zone has an indicated resource of 682,000 ounces of contained gold and an inferred resource of 353,000 ounces of contained gold. The Ortacam Zone has an inferred resource of 124,000 ounces of contained gold.


Ian Atkinson, President and CEO of Centerra Gold said: "2012 was another successful year for Centerra, increasing our reserve and resource base to over 16 million contained ounces of gold, which does not include the 4 million contained ounces of gold in the inferred category. In 2012, we more than replaced reserves mined at Kumtor with the new KS-13 life-of-mine plan and generated our initial resource at our 100% owned Oksut deposit in Turkey."


Year-end Reserves and Resources


Reserves


During 2012, Centerra's proven and probable gold reserves increased by 3.6 million contained ounces (before accounting for 2012 production) to 11.1 million ounces of contained gold, compared to 8.1 million ounces as of December 31, 2011. This represents an increase of 45% before accounting for 534,000 contained ounces processed at Kumtor and Boroo during 2012. The total reserve increase is the result of the significant expansion of the Kumtor Central Pit and is described in detail in a new NI 43-101 technical report filed on SEDAR in December 2012. All 2012 year-end reserves were estimated using a gold price of $1,350 per ounce compared to $1,200 per ounce at December 31, 2011.


For the 2012 Kumtor year-end reserve statement in this news release, the KS-13 model has been updated from the reserve estimate completed and published at the end of September 2012 by the addition of 17 diamond drill holes and accounting for the gold production and mine reconciliation completed during the last quarter of 2012.


In Mongolia, at the Boroo mine, proven and probable reserves total 178,000 contained ounces of gold after accounting for approximately 110,000 contained ounces being processed in the mill and or loaded on the heap leach pad in 2012. The remaining reserves are now entirely within existing ore stockpiles on surface. At the current reserve gold price assumption, the Boroo operation can continue to feed the mill from stockpiles for approximately two more years and operate and recover gold from the heap leach pad into 2014. At the Gatsuurt project, proven and probable reserves remain unchanged at 1.5 million ounces of contained gold.


Resources


As of December 31, 2012, Centerra's measured and indicated resources decreased by 23% or 1.5 million ounces over the December 31, 2011 figures to total 5.1 million ounces of contained gold, compared to 6.6 million contained ounces as of December 31, 2011. The majority of this decrease is a result of the conversion of previously outlined Kumtor Central Pit measured and indicated open pit resources into mineral reserves as a result of the KS-13 Pit expansion. This conversion of resources to reserves has been offset by increased resources at Kumtor described below and the addition of 682,000 contained ounces of new indicated resources at the Oksut project.


As of December 31, 2012, Centerra's inferred resources increased by 22,000 contained ounces over the December 31, 2011 figures to total 4.1 million ounces of contained gold, the conversion of Kumtor underground resources into reserves within the KS-13 expanded pit was offset by new high grade resources outlined below the KS-13 pit design and the addition of 477,000 contained ounces of new inferred resources at the Oksut project.


At Kumtor, as of December 31, 2012, measured and indicated resources total 2.7 million ounces of contained gold, compared to 4.8 million contained ounces as of December 31, 2011. The decrease of 2.1 million ounces is largely attributable to the significant conversion of resources to reserves as a result of the expanded Central Pit at Kumtor. The expansion of the open pit converted approximately 2.0 million ounces of contained gold of measured and indicated open pit resources to reserves. Exploration drilling in 2012 added 400,000 ounces of contained gold to measured and indicated resources and 21,000 ounces of contained gold of the inferred open pit resources were upgraded to measured and indicated resources. These increases in the measured and indicated open pit resources were offset by a reduction of 678,000 ounces of contained gold because of the smaller resource limiting shell used for resource estimation.


In addition, as a result of detailed delineation drilling completed in the underground Stockwork Zone in 2012, 121,000 ounces of contained gold were upgraded from the inferred category to high-grade underground Stockwork Zone indicated resources.


Kumtor's inferred resources decreased by 437,000 contained ounces of gold from 2011 year-end, to total 2.7 million contained ounces of gold at December 31, 2012, which includes 1.9 million contained ounces of high-grade underground inferred resources in the SB and Stockwork Zones. The inferred resources in the high-grade underground SB Zone decreased by 0.5 million contained ounces to 1.2 million contained ounces of gold with an average grade of 11.2 g/t. This reduction is the result of the expansion of the Central Pit, which captured 1.2 million ounces of contained gold that were previously classified as part of the high-grade underground SB Zone inferred resources.


These inferred resources are now within the new open pit design and therefore, are included in the Central Pit as probable reserves. This reduction in inferred resources has been partially offset by the positive exploration results in 2012 including 17 additional diamond drill holes completed in the fourth quarter of 2012 after the KS-13 resource estimate was announced in November 2012. These holes have extended the SB Zone to the southwest and northeast adding 651,000 contained ounces of gold to the high-grade underground SB Zone inferred resource, which remains open at depth.


In addition, the high-grade underground Stockwork Zone inferred resource increased by 76,000 ounces of contained gold to 705,000 ounces of contained gold with an average grade of 11.0 g/t. Underground drilling in the Stockwork Zone added 168,000 contained ounces of gold to the inferred resources which was partially offset by the conversion of 121,000 contained ounces of gold to high grade Stockwork Zone indicated resources with an average grade of 10.7 g/t.


At the 100% owned Oksut project in Turkey, Centerra calculated its initial resource estimate based on the successful 2012 drilling program. As of December 31, 2012, the Oksut project has an indicated resource of 682,000 ounces of contained gold and an inferred resource of 477,000 ounces of contained gold. The resource estimation is contained in two zones; the Ortacam North Zone which has an indicated resource of 682,000 ounces of contained gold and an inferred resource of 353,000 ounces of contained gold and the Ortacam Zone which has an inferred resource of 124,000 ounces of contained gold.


The initial Oksut indicated and inferred resource estimate includes only oxide mineralization and is based upon 52 drill holes in the Ortacam North Zone and 21 drill holes in the Ortacam Zone. The resource estimate is contained within a preliminary whittle shell using a cut-off grade of 0.2 g/t and raw assays were top-cut to 15 g/t before compositing.


At the ATO project in Mongolia, measured and indicated contained gold, resources have decreased by 53,000 contained ounces of gold from 2011 year-end, to a total of 771,000 contained ounces of gold at December 31, 2012. Extensive metallurgical testwork completed in 2012 has resulted in revised lower process recovery and net smelter return assumptions for the sulphide mineralization which has lowered the contained gold resources. This has also decreased the corresponding contained silver, lead and zinc resources. Some of the decrease has been offset by increased recovery assumptions for the oxide mineralization and the addition of 50 new exploration drill holes completed in 2012.



Inferred resources at ATO have also decreased by 18,000 contained ounces of gold from 2011 year-end, to a total of 8,000 contained ounces of gold at December 31, 2012 as a result of the same factors outlined above.


2012 year-end resource estimates on the Boroo, Gatsuurt, Ulan Bulag properties in Mongolia and Kara Beldyr property in Russia remain unchanged from those outlined at the end of 2011.

1.  The mineral reserves have been estimated based on a gold price of $1,350
    per ounce. 
2.  Mineral resources are in addition to reserves. Mineral resources do not
    have demonstrated economic viability. 
3.  Centerra's equity interests as of this news release are: Kumtor 100%,
    Gatsuurt 100%, Boroo 100%, Ulaan Bulag 100%, ATO 100%, Oksut 100% and
    Kara Beldyr 70%. All contained ounces in table above are shown on a 100%
    basis. 
4.  Open pit resources occur outside the current ultimate pits which have
    been designed using a gold price of $1,350 per ounce. 
5.  The open pit reserves and resources at Kumtor are estimated based on a
    cut-off grade of 0.85 gram of gold per tonne for the Central Pit and 1.0
    grams of gold per tonne for the Southwest, Sarytor and Northeast
    deposits. 
6.  Underground resources occur below the Central pit and are estimated
    based on a cut-off grade of 6.0 grams of gold per tonne. 
7.  The open pit reserves and resources at Boroo are estimated based on a
    0.5 gram of gold per tonne cut-off grade. 
8.  The open pit reserves and resources at Gatsuurt are estimated using
    either a 1.2, 1.4 or 1.5 grams of gold per tonne cut-off grade depending
    on ore type and process method and include the Central Zone and Main
    Zone deposits. 
9.  The open pit resources at Ulaan Bulag are estimated on a cut-off grade
    of 0.8, 0.9 or 1.0 grams of gold per tonne depending on ore type and
    process method. 
10. The ATO open pit resources are estimated based on a Net Smelter Return
    (NSR) cut-off grade of $6.50 NSR per tonne for oxide mineralization and
    $25.50 NSR per tonne for sulphide mineralization. 
11. The open pit resources at Kara Beldyr are estimated based on a 1.0 gram
    of gold per tonne cut-off grade and the contained ounces are shown on a
    100% basis. 
12. The Open pit resources at Oksut are estimated based on a 0.2 gram of
    gold per tonne cut-off grade. 
13. A conversion factor of 31.10348 grams per ounce of gold is used in the
    reserve and resource estimates. 
14. Numbers may not add up due to rounding. 
15. Inferred mineral resources have a great amount of uncertainty as to
    their existence and as to whether they can be mined economically. It
    cannot be assumed that all or part of the inferred resources will ever
    be upgraded to a higher category. 
16. In July 2009, the Mongolian Parliament enacted legislation that would
    prohibit mineral prospecting, exploration and mining in water basins and
    forest areas in the territory of Mongolia and provides for the
    revocation of mining and exploration licenses affecting such areas. The
    legislation exempts any "mineral deposit of strategic significance". If
    the legislation is not repealed or amended or if Gatsuurt is not
    designated as a "mineral deposit of strategic importance" that is exempt
    from this legislation, mineral reserves at Gatsuurt may have to be
    reclassified as mineral resources or eliminated entirely.

Kyrgyz Republic


During the fourth quarter of 2012, exploration drilling programs continued in the Kumtor Central Pit and from Declines 1 and 2, infilling and testing for extensions to the SB Zone and the SW Extension of the Kumtor deposit.


Kumtor Pit


In the Central Pit, drilling focused on infilling and expanding portions of the SB and Southwest Extension Zones within and below the KS-13 pit design. Eleven holes were completed and another four holes were in progress at the end of the quarter.


Drilling results received in the quarter include a number of robust intercepts that largely infill the KS-13 reserve and the SB Underground inferred resource published on November 7, 2012. Better results include 6.8 g/t gold over 95.3 metres (including 14.0 g/t over 26.6 metres) in hole D1675 and 5.1 g/t gold over 75.4 metres in D1671. Both holes targeted the SB Zone on Section 18 and lie within the limits of the KS-13 pit design. Forty metres to the east on Section 22, holes D1674 intersected 10.1 g/t gold over 38.0 metres (including 21.2 g/t over 8.4 metres). D1674A, a re-drill of the ore zone from a wedge higher up in hole D1674, intersected 10.2 g/t gold over 63.0 metres (including 34.7 g/t over 3.9 metres and 20.7 g/t over 11.9 metres). These holes infill the SB Zone in the lower portion of the KS-13 pit. Another hole, D1682, intersected 5.8 g/t gold over 87.9 metres (including 11.8 g/t over 21.0 metres and 19.8 g/t over 4.0 metres) immediately below the KS-13 pit and within the SB Underground inferred resource.


Hole D1687, designed to test the SB Zone some 250 metres below the KS-13 pit bottom, intersected 4.4 g/t gold over 105.8 metres (including 15.0 g/t over 3.7 metres). It is an infill hole within the SB Underground inferred resource.


Hole D1681 intersected 12.4 g/t gold over 47.9 metres (including 26.8 g/t over 11.2 metres) on Section 26 near the bottom of the new KS-13 pit design. Forty metres further east on Section 30, hole D1690 intersected 8.3 g/t gold over 57.2 metres (including 16.6 g/t gold over 21.3 metres). This hole also lies within the KS-13 pit.


Further east on Section 38, hole D1692 intersected 6.0 g/t gold over 40.0 metres (including 15.1 g/t over 3.5 metres) and 5.8 g/t gold over 49.0 metres (including 13.1 g/t over 10.4 metres). Forty metres east on Section 42, hole D1672 intersected 8.9 g/t gold over 44.9 metres (including 37.3 g/t gold over 4.0 metres and 18.3 g/t over 4.1 metres) and 6.3 g/t gold over 9.7 metres (including 15.0 g/t over 3.3 metres) on Section 42. Both holes lie 150 to 200 metres below the KS-13 pit and have had a positive impact on year-end resource calculations.


All of these drilling results have been incorporated into the year-end resource update.


Exploration drilling will continue to infill and expand the SB Underground resource in 2013 subject to the availability of drill platforms in the Central Pit. Drilling is also planned for the western limits of the Southwest Extension of the SB Zone and for the Sarytor and Northeast deposits.


Decline Exploration


Nine exploration holes were drilled from Declines 1 and 2 to infill portions of the Southwest Extension and the SB Zones. Seven of the nine holes stopped short of their targeted depths due to difficult drilling conditions, but all nine holes intersected zones of gold mineralization. Better results include 40.7 g/t gold over 2.0 metres, 14.4 g/t gold over 5.0 metres and 5.2 g/t gold over 30.5 metres in hole UD1676 on Section -14 and 18.0 g/t gold over 2.0 metres and 10.4 g/t gold over 15.5 metres in UD1689 on Section -6. Further east on Section 6, hole UD1666 intersected 6.9 g/t gold over 22.6 metres (including 17.5 g/t over 5.5 metres). Also, on Section 6, hole UD1680 reported 3.8 g/t gold over 13.0 metres before it stopped short of completion due to drilling problems.


Two deep underground holes were drilled from Decline 2 to target deeper portions of the SB Zone that were inaccessible from the Central Pit. Hole UD1670 intersected 2.4 g/t gold over 55.2 metres before being abandoned, and hole UD1688 intersected 3.1 g/t gold over 49.9 metres (including 8.1 g/t gold over 3.2 metres) before also being abandoned for technical reasons.


True widths for the mineralized zones are typically from 70 to 95% of the stated intercept.


Underground drilling ended in November 2012, following the Company's decision to expand the Kumtor Central Pit and cease underground development activities.


Regional Exploration


No regional exploration activities took place during the quarter.


Mongolia


ATO Project


Thirty holes were completed on the ATO project during the fourth quarter of 2012. The holes were drilled to test for extensions to the current resource along the limits of the pipe-like bodies and in apparent feeder zones at depth. Better results from these 30 holes and from 26 holes completed in the prior quarter include:

###PRECONTENT2###

True widths of the mineralized zones are from 50 to 90% of the stated interval.


Overall, drilling results close off mineralization on the west side of Pipes 1 and 2 and expand the eastern limits of Pipes 1 and 4. The drilling also extends mineralization at depth, where precious metal values decrease and base-metal values increase. These drilling results have been included in the 2012 year-end resource update for ATO.


Russia


Kara Beldyr Joint Venture


Eleven holes were drilled at Camp Zone during the fourth quarter of 2012 to infill areas of initial high-grade results. Four holes were also completed at the Baran Zone to test a large gap in the existing drilling. Better results from Camp Zone include:

###PRECONTENT3###

The drilling extends Camp Zone 150 metres to the northeast before closing it off. Drilling also closed off the deposit at depth. Several holes are planned to test a soil anomaly approximately 500 metres northeast of Camp Zone.


Results from the four holes at Baran Zone include one narrow, high-grade intercept (19.0 g/t gold over 2.4 metres in KB-162). Overall, drilling results outline a narrow, discontinuous zone of mineralization and enveloping alteration. No additional work is planned at Baran Zone.


True widths for the mineralized zones are from 20 to 90% of the stated intercept.


The results of the 2012 Kara Beldyr program are being compiled to determine the size and scope of the 2013 exploration program.


Turkey


Oksut Project


In the fourth quarter of 2012, 18 diamond drill holes were completed and final results were received for 23 holes. Fifteen infill and step-out holes were drilled at the Ortacam North deposit, and a single hole each was completed at the Ortacam deposit (ODD96), Kizilagil (ODD71) and Devetasi (ODD78). Better results from the quarter include:

###PRECONTENT4###

True widths for the mineralized zones are from 50 to 90% of the stated intercept.


Results from holes ODD70-89 were previously reported in Centerra Gold's news release of December 12, 2012. Results from holes ODD90-94 and ODD96 are new results received after the December 12th news release. All of these drilling results have been used in the year-end resource calculation.


Step-out drilling at 100-metre spacing has closed off the Ortacam North deposit to the north and west beyond the limits of the diatreme-breccia host rock. The deposit remains open to the east, beneath andesite cover, and to the southeast towards the smaller Ortacam deposit. The deposit is also open at depth below the oxide/sulphide boundary where several holes have intersected gold and supergene copper.


The Ortacam North deposit measures approximately 550 by 250-300 metres in plan and, locally, is up to 200 metres thick. The deposit is zoned outward from a core of massive silica breccia to enveloping vuggy quartz + alunite rock. Quartz-kaolinite rock, commonly developed in massive andesite, surrounds the deposit and generally contains less than 0.2 g/t gold.


PQ core from a metallurgical drill hole was composited into three sample types for bottle-roll and column leach test work at the SGS facility in Cornwall, England. Final results are expected in the first quarter of 2013 and will be used to plan a more extensive program of metallurgical drilling and column-leach test work.


Results were received for 99 core samples submitted for specific gravity measurements. The principal ore-bearing rock types - massive silica and vuggy quartz-alunite rock - displayed a wide range of values in the initial results. Another 117 samples were collected and submitted for analysis late in 2012. All 218 values have been used to assign densities in the year-end resource model.

Material Assumptions & Risks


Material assumptions or factors used to estimate reserves and costs for 2013 include the following:

###PRECONTENT5###

The assumed diesel price of $0.80/litre at Kumtor assumes that no Russian export duty will be paid on the fuel exports from Russia to the Kyrgyz Republic. Diesel fuel is sourced from separate Russian suppliers for both sites and only loosely correlates with world oil prices. The diesel fuel price assumptions were made when the price of oil was approximately $87 per barrel.


Other material assumptions include the following:

###PRECONTENT6###

Reserve estimates and cost forecasts are forward-looking information and are based on key assumptions and subject to material risk factors. If any event arising from these risks occurs, the Company's business, prospects, financial condition, results of operations or cash flows and the market price of Centerra's shares could be adversely affected. Additional risks and uncertainties not currently known to the Company, or that are currently deemed immaterial, may also materially and adversely affect the Company's business operations, prospects, financial condition, results of operations or cash flows and the market price of Centerra's shares.
