Alamos Gold Inc. provided production guidance for the first and second half of 2026 and full year of 2026, 2027 and 2028. For the first half of 2026, the company expects total gold production of 270,000 oz - 310,000 oz.

For the second half of 2026, the company expects total gold production of 300,000 oz - 340,000 oz.

For the year 2026, the company provides gold production of 570,000 ounces to 650,000 ounces. Consolidated production is expected to increase 12% from 2025 to a range of between 570,000 and 650,000 ounces. This is expected to be driven by the ramp up of underground mining rates through the year at Island Gold in conjunction with the completion of the Phase 3+ Expansion towards the end of 2026, as well as increased mining rates at Young-Davidson. Production is expected to be higher in the second half of the year driven by the ongoing ramp up at Island Gold. Compared to Previous Guidance, 2026 production guidance is approximately 7% lower reflecting slightly lower production from the Canadian operations, partially offset by an increase from the Mulatos District. This reflects slightly lower grades at Young-Davidson, and a more conservative ramp up of underground mining rates at Island Gold with the shaft to be operational toward the end of 2026.

for the year 2027, the company provides gold production of 650,000 ounces to 730,000 ounces as compared to previous guidance of 680,000 ounces to 730,000 ounces. Gold production is expected to increase to a range of between 650,000 and 730,000 ounces in 2027, a 13% increase from 2026, and 27% increase from 2025. The Island Gold District is expected to drive this growth with 2027 representing the first full year operating from the new shaft infrastructure, supporting higher underground mining rates. The completion of the IGD Expansion in 2028 is expected to drive a further increase in production to a range of 755,000 to 835,000 ounces, representing a 15% increase from 2027 and cumulative 46% increase from 2025.

For the year 2028, the company provides gold production of 775,000 ounces to 875,000 ounces.

Production expected to increase 12% in 2026 and 46% by 2028 to between 755,000 and 835,000 ounces: production guidance for 2026 decreased relative to the previous guidance provided in January 2025 ("Previous Guidance"), with slightly lower production from Canadian operations partially offset by an increase at the Mulatos District. Production guidance for 2027 is largely in-line with Previous Guidance and represents a 13% increase from 2026. A further 15% increase is expected in 2028, driven by the completion of the Island Gold District Expansion ("IGD Expansion") for a cumulative 46% increase in production relative to 2025.
