DENVER (AP) — Authorities on Monday were trying to determine the source of carbon monoxide blamed for killing two men and injuring others at a mine in southwestern Colorado.

Ouray County officials said they have ruled out an explosion and mine collapse as the immediate cause of the deaths of Nick Cappanno, 34, of Montrose and Rick Williams, 59, of Durango on Sunday at the Revenue-Virginius mine.

However, the Montrose Daily Press and The Denver Post reported that investigators were looking at whether a small blast on Saturday at the underground gold, silver and lead mine may have been the cause of the carbon monoxide problem........more......

I have no idea why the title says carbon dioxide and body of article says carbon monoxide....

Feds: Miners entered area where blast occurred

DENVER — Two Colorado miners who died of carbon monoxide poisoning apparently entered an area of the mine where an explosive had been previously detonated, federal investigators said Monday.

Nick Cappanno, 34, of Montrose and Rick Williams, 59, of Durango were killed at the start of their shift Sunday morning at the Revenue-Virginius mine near Ouray (yoo-RAY') in southwestern Colorado.

Preliminary information indicates one of the men entered the area first, said Amy Louviere, a spokeswoman for the U.S. Mine Safety and Health Administration, which is investigating the deaths.

When the first miner didn't return, she said, a foreman went looking for him. Both men were later found by other miners working in the area, and those miners immediately evacuated the underground gold, silver and lead mine, she said.

Mine manager Rory Williams previously said there was a blast in the mine to remove rock on Saturday that may have been a source of the carbon monoxide. Louviere said the blast occurred during the previous shift, so it likely happened on Saturday........

At a news conference late Sunday, Rory Williams said all of the miners had air packs to help them breathe in an emergency, but he didn't know whether they carried gas detectors to alert them to dangerous levels of carbon monoxide. He said there didn't appear to be any equipment malfunction.......

Robert Ferriter, a senior mine safety specialist at the Colorado School of Mines, said routine air tests done after blasting should have detected any problems from earlier blasting at the Revenue mine.......

But was that testing done?
