Kinross's Alaska mine output falls 29% as less Manh Choh ore reaches the mill

Kinross Gold's two Alaska mines produced 29% less gold and silver in the third quarter than a year earlier, and each ounce sold cost 46% more to produce, the company reported Wednesday.

Most of the drop traces to Manh Choh, the mine near Tok whose ore is trucked to Kinross's Fort Knox mill northeast of Fairbanks. The mill ran 185,000 tonnes of Manh Choh ore, down from 286,000 a year earlier, and Kinross said production fell "primarily due to the decrease in tonnes processed and mill grades from Manh Choh."

Rain also slowed mining. The operation mined 23% less ore "as a result of significant rainfall impacting mining productivity," the company's quarterly report says.

Kinross reports the two mines as one operation. Together they produced 80,118 gold-equivalent ounces, down from 112,181. That measure converts silver to its value in gold.
