SANTIAGO, Chile, Sept. 4 (UPI) -- Chilean President Sebastian Pinera said work on a third rescue tunnel would begin soon at the site where 33 miners have been trapped for more than a month.

The president said the third tunnel would be dug by an oil-well drill and work would get under way before Chile's Sept. 18 bicentennial, The Wall Street Journal reported Saturday.

The petroleum drill would join two other drilling operations at the San Jose Mine where experts anticipate the men will be stuck until the end of the year.

Rescuers were in the midst of using three existing narrow shafts to lower supplies to the men and rig a video system they can use to communicate with the surface and watch next week's Chile-Ukraine soccer match, The Journal said.

The shaft also was used to send up a poem written by one of the miners. The Journal said the verse described their agonizing wait during the initial rescue effort and ended "PS. We are in your hands Chile."
