2.3 Million Ounces of Reserves Added to the Main Kumtor Pit SB Zone

Centerra Gold Centerra Gold Inc. (TSX: CG) is the gold mining company headquartered in Toronto, Canada.

The company was formed and went public in 2004 when Saskatoon, SK-based Cameco Corp.
 Inc. (TSX TSX Toronto Stock Exchange (TSE before April, 2002)

TSX True Space Extension
:CG) today issued updated estimates on the reserves and resources at its operating mines and advanced projects. At the Kumtor Mine 2.3 million ounces of reserves have been added, before accounting for mining of 614,000 ounces of contained gold in 2005, with almost all of this addition being the result of drilling at the SB Zone at the south end of the currently operating pit. Reserve grade has also increased by 18% from 3.3 g/t to 3.8 g/t gold due to the higher grade mineralization Mineralization

 in the SB Zone. An assessment of the additional capital expenditures required to develop these reserves is nearing completion. At the Boroo Mine 349,000 ounces have been added, which replaces reserves mined in 2005. Additionally, 2.5 million ounces of measured and indicated resources have been added to Centerra's resource base.

As of December December: see month.  31, 2005, on a 100% project basis, Centerra's proven and probable reserves totaled 6.2 million ounces of contained gold (Centerra's share is 6.1 million ounces), which includes an increase of 2.7 million ounces offset by 917,000 ounces mined in 2005.

As of December 31, 2005, on a 100% project basis, Centerra's measured and indicated resources totaled 6.3 million ounces of contained gold (Centerra's share is 5.8 million ounces), which includes an increase of 2.5 million ounces over the December 31, 2004 figures.

The significant increase in reserves and resources comes from the excellent results of exploration drilling. There is only a minimal increase attributable to using a gold price of $400 per ounce ounce, in zoology

During 2006 our aggressive exploration program will be continued and expenditures are expected to be $21 million."

Exploration at Kumtor in 2006 will be focused on extending the SB Zone down dip and along strike where the high grade nature of the mineralization offers the potential for further exploitation. Additional drilling is also planned for the NB Zone, at the north end of the pit, to test for strike extensions of the mineralization to the north. At Kumtor planned exploration expenditures for 2006 are $11.4 million.

Kumtor Drilling Update

During December and January January: see month.  the Company completed a further five drill holes to test the SB Zone at the south end of the Kumtor pit. One hole was drilled to infill in·fill

Kumtor Mine

Kumtor's reserves and resources include the Kumtor main pit, the Southwest Southwest or south west is the ordinal direction halfway between south and west, the opposite of northeast.

Southwest or south west may also refer to:
  • The Southwestern United States
  • Southwest China
 Zone and the Sarytor Zone. Results for the Kumtor Pit and the two satellite deposits are discussed separately below:

a) The reserve estimate at the Kumtor main pit was prepared using a cutoff grade of 1.3 g/t gold and cutting high grade values to 60 g/t gold, which are the same parameters used in the 2004 reserve estimate. The proven and probable reserves, including the stockpiles, are estimated at 4,670,000 ounces of contained gold at an average grade of 3.9 g/t gold, compared to 2,966,000 ounces of contained gold at an average grade of 3.3 g/t gold as at the end of 2004. In 2005, 614,000 contained ounces of gold were fed to the mill, and 2,318,000 ounces of contained gold were added to the reserves. Most of the increase in reserves is due to the positive exploration results and the resulting new pit design for the SB Zone.

Measured and indicated resources are estimated at 2,705,000 ounces of contained gold at an average grade of 4.0 g/t gold using a 1.3 g/t gold cutoff grade. These resources are not included in the reserves. This is a increase of about 940,000 ounces of gold from the 2004 year-end year-end also year·end

Using a 5.0 g/t cutoff grade, there are approximately 5.3 million tonnes of material averaging 8.2 g/t gold for a total of 1,400,000 ounces of contained gold within the measured and indicated resources quoted above.

b) The Southwest Zone at Kumtor is a satellite deposit located three kilometres southwest of the Kumtor mill. Reserve and resource models have not been updated for the Southwest Zone during 2005 due to the limited amount of drilling completed in 2005 in the vicinity of the resource area. Using a cutoff grade of 1.3 g/t gold and cutting high grade values to 60 g/t gold, this zone is estimated to contain probable reserves of 283,000 ounces of contained gold at an average grade of 3.2 g/t gold and additional indicated resources of 149,000 ounces of contained gold at an average grade of 3.8 g/t gold. To be consistent with our other operations inferred resources totaling 285,000 ounces of contained gold have been reclassified and removed from the resource statement.

c) The Sarytor Zone at Kumtor is a satellite deposit located five kilometers from the Kumtor mill that was drilled during 2005. Using a cutoff grade of 1.3 g/t gold and cutting high grade values to 20 g/t gold, this zone is estimated to contain indicated resources of 167,000 ounces of contained gold at an average grade of 3.0 g/t gold. Inferred resources are estimated at 246,000 ounces of contained gold at an average grade of 2.7 g/t gold.

The Sarytor Zone has been significantly upgraded in 2005 and additional drilling is planned for 2006.

Based on these estimates, the additional reserves will extend the Kumtor mine life by almost three years.

 and mine engineering staff using cutoff grades ranging from 0.9 g/t gold to 1.1 g/t gold depending upon the type of material and the associated gold recovery. High grade values were also cut using variable limits ranging from 20 g/t gold to 90 g/t gold depending on the mineralized zone.

- On a 100% project basis, the proven and probable reserves, including the stockpiles, are estimated at 1,218,000 ounces of contained gold, compared to 1,172,000 ounces of contained gold as at the year-end 2004. In 2005, 303,000 contained ounces of gold were fed to the mill, and 349,000 ounces of contained gold were added to the reserves. This will extend the mine life by over one year. The additional reserves are a result of exploration success and a pit expansion to the north of Pit 6, and changes in pit designs for Pits 3 and Pit 2.

- Measured and indicated resources are estimated at 201,000 ounces of gold using the same variable cutoff grades as the reserve estimate. These resources are in addition to the proven and probable reserves and are similar in magnitude to the resources reported last year.

- The Gatsuurt resource base has been significantly expanded by recent drilling programs. A feasibility study "A Feasibility Study" is an episode of the original The Outer Limits television show. It first aired on 13 April, 1964, during the first season. It was remade in 1997 as part of the revived The Outer Limits series with a minor title change.  was completed in 2005. The preferred option, supported by the study, is to modify the existing Boroo facility by adding a bio-oxidation (BIOX) circuit and processing the refractory refractory

The annual amount of depletion may, ironically, provide a tax deduction for the company exploiting the resource because if the resource they are exploiting runs out, they will no longer be able  of the Boroo reserves. This has the potential to significantly extend the life of the Boroo facility. Further analysis to optimize optimize - optimisation  the project is continuing. RPA has been retained to complete an updated NI 43-101 technical report on the Gatsuurt project incorporating the Main Zone.

- The Gatsuurt deposit is open at depth. Exploration drilling will continue in 2006 to further evaluate the high grade mineralization beneath the Gatsuurt Central Zone as a potential underground mining opportunity with initial planned expenditures of $1 million.

 of 10 feet (3.1 metres) and cutting high-grade values to 70 g/t gold, the indicated resources are estimated to be 1,201,000 ounces of contained gold. Additional inferred resources are estimated at 128,000 ounces of contained gold.

- The updated estimate has resulted in a 52% increase in contained gold in the indicated resources category over the 2004 year-end resource estimate. This increase is due to upgrading inferred resources in the 69 Zone through additional drilling, the completion of two additional holes into a high grade section of the JB Zone and increasing the top cut levels from 40 g/t gold to 70 g/t gold.

- Exploration drilling will continue in 2006 with the focus on expanding the resource base and improving the project's viability with initial planned Joint Venture expenditures of $2.5 million with Centerra's share being $1.5 million.

  of reserves. The extent to which resources may ultimately be reclassified as proven or probable reserves is dependent upon the demonstration of their profitable recovery. The evaluation of reserves or resources is always influenced by economic and technological factors, which may change over time. Resources figures included herein have not been adjusted in consideration of these risks and, therefore, no assurances can be given that any resource estimate will ultimately be reclassified as proven or probable reserves.
