Alamos Gold Inc. Operational Update and Guidance Revision

Alamos Gold Inc. has provided an operational update for its Canadian operations, specifically the Young-Davidson and Island Gold mines. The Young-Davidson mine experienced seismic events and power outages in the second quarter, impacting production and leading to revised lower production and higher cost guidance for Q2 and full-year 2026. The company expects mining rates to average 5,000 tonnes per day for the remainder of the year, with optimizations planned for the second half. Island Gold operations continue to perform well, with increased underground mining rates and Magino mill throughput, expecting significant production growth in the second half of 2026. Alamos also announced the elimination of remaining legacy Argonaut gold hedges for an effective price of approximately $4,458 per ounce and repurchased $30 million of shares in May under its Normal Course Issuer Bid. The company anticipates stronger production in the second half of 2026, driven by Island Gold, and will provide further guidance updates with its Q2 financial results.
