Alamos Gold (AGI.TO, AGI) was down 2.9% in after-hours New York trading after the company on Thursday said it is lowering quarter production guidance on lower production from its Young-Davidson mine in northern Ontario following two seismic events at the mine and a power outage following storm damaged regional electricity infrastructure.
The company said the seismic events caused no injuries, but damaged mine infrastructure and limited access to high-grade stopes. It expects tonnage to drop to 5,000 tonnes per day for the remainder of the year.
A storm late in May damaged the power line that connects the town of Kirkland Lake to the mine, causing three days of downtime.
The company said it now expects the mine to produce 130,000 to 135,000 ounces of gold in the second quarter, in-line with first-quarter output but below guidance.
"We are disappointed with the operational challenges at Young-Davidson, and are working diligently to review and optimize the mining sequence to support higher mining rates going forward. The first half has been challenging, but we expect stronger production into the second half of this year," chief executive John McCluskey said.
The company's shares were last seen down US$1.06 to US$35.28 after hours. They closed down C$1.33 to US$51.40 on the Toronto Stock Exchange.
