* Partial mineralized interval, only intercept within section corridor +/- 15m, along section line. Mineralized intervals are greater than 0.10 g/t Au. Higher grade sub-intervals are greater than 1.00 g/t Au. Individual assays are top cut to 30 g/t Au prior to composite calculation. True widths for mineralized zones are about 20% to 50% of stated down hole interval. This information should be read together with our news release of February 9, 2012. Ian Atkinson, a Certified Professional Geologist, is Centerra’s qualified person for the purpose of National Instrument 43-101. Tables are current as of December 31, 2011.
