BISBEE, Ariz. (AP) - Freeport McMoRan says it will be conducting an evaluation of the Queen Mine in Bisbee to see what can be done about safety concerns that could force the end of mine tours.
The underground mine has become a popular tourist attraction.
The mining company met with city officials last week to discuss the concerns, which include fluctuating levels of radon gas.
Bisbee officials said the company notified them that it was planning to terminating the lease for the mine tour because of the concerns. The termination had been scheduled to take effect in 60 days.
But company officials said Tuesday they would determine whether any practical measures could be taken to ensure the safety of tour employees. If something can be done, they would work with the city on a new lease agreement.
