Notes:

This information should be read together with our news release of February 24, 2021. Assays are reported true values without top cutting. Reported intervals are longer than 2.0 m, grade greater than 0.1 g/t Au or 0.1% Cu and include maximum internal waste of 4.0 m where it exists. Intervals less than 2.0 m but with grade above 1.0 g/t Au are also reported. Significant assay intervals reported represent apparent widths due to the undefined geometry of mineralization in this zone, relationship between fault blocks, and conceptual nature of the exploration target.C. Paul Jago, a Member of Engineers and Geoscientists British Columbia, is Centerra’s qualified person for the purpose of National Instrument 43-101.* Indicates drill hole completed in previous quarter, assay results returned in current quarter.
