Insights

Mining sector and project permitting analyst

Key operating permits extend Mount Milligan to 2035 with planned throughput growth.

Centerra Gold has secured an amended environmental assessment and all related permits allowing its Mount Milligan mine to operate through 2035. These approvals also cover a 10% increase in plant throughput beginning in 2028 plus added stockpile capacity, which can support higher processing volumes and more flexible ore feed management.

The permits were obtained under an expedited provincial process, after Mount Milligan was selected in January 2025 as one of four mining projects prioritized for permitting to support economic development. Centerra is also progressing engineering and other studies aimed at obtaining future authorizations needed to deliver a mine life to 2045 as outlined in a pre-feasibility study that referenced a fully funded $186 million growth capital plan.

Management characterizes Mount Milligan as central to its organic gold growth strategy and points to expected ongoing employment for more than 1,000 workers and increased business opportunities for First Nations and regional communities. The Premier of British Columbia describes the expansion as securing hundreds of jobs and generating hundreds of millions of dollars in additional economic benefits, while emphasizing that environmental, safety, and First Nations consultation standards remain in place.

We are encouraged by the results of the process that has just concluded and believe that when government, First Nations, and industry are mutually committed to responsible resource development, we can achieve great things. The extended life of mine is expected to provide consistent employment to more than 1,000 workers and increase business opportunities to First Nations, surrounding communities, and the province, representing a significant economic driver for northern communities in British Columbia.”

The Honourable, David Eby, Premier of British Columbia, commented “The Mount Milligan mine expansion will ensure hundreds of good, family-supporting jobs are secure for years to come, while generating hundreds of millions of dollars in additional economic benefits for the region and beyond.
