Ghana EPA issues pre-closure notice to Namdini gold mine over spill

Namdini Pre-Closure Notice Details and Tailings Spill

The regulatory action centers on infrastructure failure at the open-pit site located approximately 50 kilometres southeast of Bolgatanga. Michael Ayamga, deputy chief executive for operations at the Environmental Protection Authority, told Reuters that a tailings pipeline disconnected, resulting in a spill. Reuters reported the enforcement action, noting that a pre-closure notice does not confirm an official shutdown of the mine, nor does the initial report establish the exact volume of the spill or the extent of any environmental damage.

The asset is operated by Shandong Gold through Cardinal Resources in partnership with a subsidiary of China Railway Construction Group, according to a January disclosure from royalty investor OR Royalties. Project projections outlined in the disclosure target production ramping up to approximately 360,000 ounces annually over the first three years at design capacity, averaging 287,000 ounces across an initial 15-year mine life. These figures represent project expectations rather than verified current annual output.

Regulatory Shifts in Ghana’s Mining Sector

The environmental notice arrives amid broader changes to how foreign operators participate in Ghana’s mining economy. Michael Ayamga described a strategic transition within the Environmental Protection Authority toward continuous oversight. “We don’t want to be reactive but proactive,” Ayamga told Reuters, adding that the agency wants to “move beyond one-off visits and audits to enforcement.”

Parallel policy shifts target local economic participation. Reuters previously reported on new rules requiring surface mining work to transition to Ghanaian-owned contractors, while mandating at least 50% local ownership for underground operations. Officials are developing wage and tender benchmarks to combat underbidding and improve worker conditions across the sector.

Operational Impacts on Royalty Holders and Project Timelines

For a newly developed facility scaling toward its target capacity, regulatory intervention introduces operational uncertainties that extend beyond immediate remediation costs. Any forced interruption can alter the timing of mineral output and subsequent cash flows for both asset owners and royalty investors. Neither a complete facility shutdown nor a quantified financial impact has been officially established in connection with the Namdini notice.
