Agnico Eagle Suspends Barnat Pit Operations After Rockslide, Lowering Future Gold Production

Agnico Eagle Mines temporarily halted mining at the Barnat open pit within its Canadian Malartic complex after a rock mass movement on the north wall, with no injuries, equipment damage, or environmental impact reported. The company is conducting a geotechnical assessment to verify stability and plan a safe restart, while the processing plant will continue operating on low-grade ore from existing stockpiles to soften near-term effects. Despite the disruption, second-quarter production is expected to be about 845,000 ounces, slightly ahead of plan. The company projects a production reduction of 60,000 to 80,000 ounces in the second half of 2026, with potential annual reductions of up to 150,000 ounces in both 2027 and 2028, placing full-year output near the lower end of its guidance of 3.3 to 3.5 million ounces. Some coverage notes the Odyssey underground mine at Canadian Malartic remains unaffected and there is no firm restart timeline yet. Market reaction included a brief dip in early trading, reflecting investor concern over the hit to future production and revenue.
The Odyssey underground mine at Canadian Malartic remains unaffected, and Agnico Eagle's plan to lift Canadian Malartic to about 1 million ounces of gold per year in the early 2030s remains intact.
Barnat was scheduled to be mined out by early 2029, indicating the incident could have multi-year effects even as the restart timeline has not been set.
The rock mass movement occurred on July 1 along the north wall in an area previously flagged for weaker geological structures and was under enhanced geotechnical monitoring with safety exclusion zones.
Agnico Eagle said updated guidance would accompany its second-quarter results on July 29.
In early trading, Agnico Eagle's stock fell about 1% to CAD 218.13 in reaction to the news.
