Shares of Alamos Gold plunged 8.3% to CA$40.61 on October 29 after the Canadian miner reported third-quarter results that fell short on both earnings and revenue, compounding investor anxiety with a delayed timeline for a critical underground expansion. Alamos Gold's Earnings Miss and Shaft Delay Slam Shares — But Is the Long-Term Growth Story Still Intact?
Shares of Alamos Gold tumbled 8.3% to CA$40.61 on October 29 after a third-quarter report that disappointed on two fronts: adjusted earnings of $0.44 per share narrowly missed analyst estimates by a penny , and revenue of $510.4 million fell short of projections by nearly $19 million . Worse, the company pushed back the timeline for a make-or-break underground expansion. For a stock that had rallied on a golden growth narrative, the quarter raises uncomfortable questions about execution.
Gold Production Fell 16%, and Higher Prices Couldn't Fully Compensate
Net earnings fell 40% year over year to $165.6 million, even as revenue rose 10%, because gold production dropped 16% to 119,000 ounces . Total cash costs surged to $1,375 per ounce and all-in sustaining costs hit $1,956, driven by inflation, lower grades at Island Gold, and weaker output at Young-Davidson . In plain terms, Alamos is mining less gold at higher cost — a combination that erodes profit margins even when gold prices are near record highs.
The Shaft Delay Pushes Cost Relief Into the Second Half of 2027
Alamos pushed back commissioning of its Island Gold shaft expansion by about a quarter to mid-2027 and flagged higher construction costs . The $835 million project is now expected to run roughly 5% over budget, implying a total cost near $877 million . The shaft is designed to replace truck haulage with a hoisting system, enabling the company to mine more tonnes at lower cost . The delay will create a production shortfall of approximately 400 tons per day versus earlier plans in the first half of 2027 — meaning the cost-savings payoff investors were banking on is now further out.
Ground Conditions and a Second Project Are Also Falling Behind
Alamos encountered an unexpected rock formation — a dyke — while excavating underground bins, requiring additional ground reinforcement . Meanwhile, underground development at the PDA project in Mexico has also been slower than planned due to contractor performance issues, which is expected to reduce PDA output in late 2027 .
The Bull Case Rests on a 2027–2030 Ramp That Keeps Getting Pushed
Management maintains Alamos can nearly double production to 1 million ounces annually by 2030 at lower costs , and a $400 million-plus net cash position provides a buffer . But with two projects now behind schedule, investors are right to ask whether the company's ambitious growth curve is a firm plan or a moving target.
