A group of miners who are trapped underground in Chile, South America, have managed to send a note to their rescuers saying that they're all alive.
The 33 men have been stuck since 5 August, four miles inside the mine after a tunnel collapsed.
Rescuers were giving up hope of finding them, but 17 days after the accident, the team got a handwritten note which the miners attached to a drill.
But it could take four months before they are finally rescued.
That's because a new shaft needs to be dug, which wide enough for them to escape.
Food and water is being sent down to them through a narrow hole that is already there.
They will also be given cameras and microphones so they can record messages for their friends and family while they wait to be rescued.
