Alamos Gold Inc. shares plunged 20% on Friday in Toronto after the company trimmed its second‑quarter gold output forecast to 130,000–135,000 ounces, down 12% from earlier guidance.

The downgrade follows seismic damage at a key mine, forcing the company to lower production estimates. Investors reacted sharply, reflecting concerns over future cash flow and reserve replacement.

A 12% cut signals tighter margins for the Canadian miner, potentially impacting dividend payouts and share‑price stability. Market watchers now scrutinize Alamos’ resilience to further disruptions.

Alamos’ stock slide underscores the sensitivity of gold producers to operational risks and the broader market’s appetite for risk‑adjusted returns.
