TORONTO, Feb. 04, 2026 (GLOBE NEWSWIRE) - Alamos Gold Inc. ( TSX:AGI; NYSE:AGI ) (“Alamos” or the “Company”) provided updated three-year production and operating guidance. The Company also outlined longer term production guidance of approximately one million ounces per year by 2030 through the larger expansion of the Island Gold District (announced on February 3, 2026) and initial production from Lynn Lake. “Our operational performance over the past year was not up to our standards and not reflective of our long-term track record. We expect to deliver a stronger performance in 2026, particularly into the second half of the year as production ramps up and costs decrease with the completion of the shaft expansion at Island Gold,” said John A.
