The 33 men trapped in a mine in northern Chile say they are in better spirits after they were able to speak to their relatives by telephone.
The news came in a video message the miners sent up to the surface.
Engineers are due to begin drilling a rescue shaft to reach the men, who have been now trapped for three weeks at San Jose gold and silver mine.
The shaft, going about 700m (2,300ft) underground, is likely to take 90 to 120 days to complete.
Once finished to a width of about 60cm, a capsule will be lowered down so the miners can be hauled out one-by-one.
Chilean Mining Minister Laurence Golborne told reporters that the last remaining piece of the drill was on its way and that engineers would be able to begin work by the end of Monday "if God wills it".
Mr Golborne had earlier said up to 10 options were being considered in the efforts to rescue the men.
But he dismissed suggestions that the men could be out within a month, saying: "Up to now there is no alternative... that would allow us to get them out in 30 days". BBC News
