Kumtor

At Kumtor, the forecast for 2013 DD&A expensed as part of costs of sales is $201 million. The increase over the three years reflects a significant expansion of the mining fleet in order to achieve higher throughput levels of materials moved and the increased stripping of waste required to access the deposit. The amortization of capitalized stripping costs is the largest component of depreciation expense in 2013 totalling $291 million. The mine equipment assets are depreciated on a straight-line basis over their estimated useful lives. The depreciation expense related to mine equipment engaged in a stripping campaign is capitalized as stripping costs ($77 million forecasted to be capitalized as stripping costs in 2013).

During 2013 Kumtor will be mining the remaining ore from cut-backs 14A and 14B and starting stripping campaigns on cut-backs 15, 16 and 17. The costs to remove waste and ice within the various cut-backs include mining operating costs such as labour, diesel and maintenance costs, as well as the depreciation expense for the mine equipment used in the stripping campaign. Labour and consumables costs (such as diesel costs) have been steadily increasing over the last several years due to both increases in price and demand with the expanding operation at Kumtor. These costs are capitalized as stripping costs and amortized over the ounces contained in the ore body exposed by the stripping campaign.

Based on the sequencing of production at Kumtor for 2013, ore from cut-backs 14A, 14B and 15 will be mined resulting in the amortization through cost of sales of $291 million in capitalized pre-stripping costs. As Kumtor completes mining of the ore from cut-backs 14A and 14B, it will amortize the remaining unamortized capitalized stripping costs of $101 million related to those cut-backs. The forecast assumes that the stripping campaign for cut-back 15 is completed in the third quarter of 2013 providing access to the ore in the third and fourth quarters. As the ore in cut-back 15 is mined in the third and fourth quarters, the amortization expense for 2013 for the capitalized stripping costs related to cut-back 15 is forecast at $190 million.

Boroo

At Boroo, the forecast for 2013 DD&A expensed as part of costs of sales is $17 million, compared to $21 million in 2012 and $10 million in 2011. The decrease in 2013 reflects the completion of mining activities in Pit 6 in 2012. The largest components of depreciation expense are related to depreciation of the mill, the administration buildings and other assets forecasted at $6 million.

Taxes

Pursuant to the Restated Investment Agreement, Kumtor's operations are not subject to corporate income taxes. The Agreement replaced the prior tax regime applicable to the Kumtor project with a simplified regime effective January 1, 2008. This simplified regime, which assesses tax at 13% on gross revenue (plus 1% for the Issyk-Kul Oblast Development Fund effective January 2009), was approved and enacted by the Parliament of the Kyrgyz Republic in 2009.

The corporate income tax rate for Centerra's Mongolian subsidiary, BGC is 25% for taxable income over 3 billion Mongolian tugriks (approximately $2.2 million at the 2012 year-end foreign exchange rate) with a tax rate of 10% for taxable income up to that amount. These tax rates will continue to apply until the expiration of the Boroo Stability Agreement in July 2013, after which Boroo's operations will be subject to a prevailing income tax rate of 25%. Royalty fees will increase from 5% under Boroo's Stability Agreement to the current graduated royalty fee structure which would charge the maximum of 10% based on current gold prices.
