1) As of December 31, 2023. Refer to Tables “Centerra Gold Inc. 2023 Year-End Mineral Reserve and Resources Summary – Gold” and “Centerra Gold Inc. 2023 Year-End Mineral Reserve and Resources Summary – Other Metals”, including their respective footnotes and the “Additional Footnotes” section below.

  • Mount Milligan: Centerra entered into an additional agreement with RGLD Gold AG, a subsidiary of Royal Gold, Inc., relating to Mount Milligan, which immediately extends the mine life by two years to 2035 and grows the mineral resources to 510 million tonnes, inclusive of reserves. For additional details, please refer to the announcement entitled “Centerra Gold Announces Mount Milligan Mine Life Extension and New Agreements with Royal Gold”, which was issued in conjunction with this news release on February 14, 2024.

  • Kemess: The Kemess underground block cave project is not a priority for Centerra’s project pipeline at this time. The prior mineral reserves and resources estimate produced for this project were completed with costs and commodity price assumptions that are no longer applicable. As a result, the Company has applied current capital, operating and metal price assumptions to reclassify the historical reserves as a blend of open pit and underground resources. Confirmation and exploration drilling, as well as technical studies are planned for 2024 and are expected to provide an updated mining and processing concept which may unlock additional value. Kemess benefits from infrastructure already on site, several permits in place, and an impact benefit agreement with its First Nation partners. Centerra remains optimistic that Kemess could be a future source of gold and copper production.
