Update: All 17 miners have been rescued and brought to safety, officials say.

Lansing, N.Y. -- Seventeen workers are stuck 900 feet below ground in an elevator shaft at the Cargill Salt Mine in Lansing, according to reports.

The Tompkins County Department of Emergency Response is sending rescue experts and equipment, according to a tweet from the department. The Ithaca Fire Department said on its Facebook page the workers had been stuck since 10:20 p.m. Wednesday, and that a crane from Auburn has arrived this morning to help in the rescue effort.

No one has been injured, and emergency crews have been in "constant communication" with the workers, a Cargill spokesman told WHCU radio.

Rescuers have given the workers blankets, heat packs, and other supplies, the Ithaca Voice reports. The Voice also quotes an unnamed emergency official as saying: "They are safe. It's just a matter of getting them out."

At 2,300 feet, the mine is the deepest in North America. The mine shaft is at Portland Point, on the eastern shore near the south end of Cayuga Lake, and the mine itself stretches north along the lake to a mile past Taughannock Point, the company's website says.

Miners will be lifted out two or three at a time, Mark Klein, communications director for Cayuga Salt Mine, told NBC News.

Syracuse.com videographer Matt Adams recently toured the mine. You can see his video at the top of this story.
