A mudslide caused by 30 hours of torrential rain killed nine gold miners and left seven others seriously injured in northwestern Brazil, police said.

The mining accident occurred late Tuesday in the jungle municipality of Mucajai, 4,000 miles northwest of Rio, federal police Capt. Maya de Guerra said in a telephone interview from Boa Vista, capital of the Amazon state of Roriama.No one had heard that the 50-foot "Deep Hole" mine had caved in until one of the miners made his way 279 miles through the jungle and arrived in Boa Vista late Thursday, de Guerra said.

"A group of miners were apparently inside the hole when a wall of mud fell in on them and swallowed them alive," de Guerra said. "Seven of the men managed to make it out alive, but they were badly hurt."
