Worker dies inspecting Nevada mine near Elko

ELKO, Nev. -- Investigators believe heat exhaustion and high humidity led to the death of a miner at an Elko County gold mine.

Barrick Goldstrike spokesman Vince Borg said an 11-person crew was assessing an underground shaft at Barrick's Storm Project north of the Meikle Mine when two men collapsed Thursday.

Dale Spring, 49, a member of Barrick's mine rescue team, was pronounced dead shortly after the noon accident, authorities said.

Another miner, Clayton Milligan, 38, was taken to Northeastern Nevada Regional Hospital in Elko and was listed in stable condition.

Authorities said the men apparently suffered heat exhaustion and were overcome by high humidity in the tunnel.

Federal safety regulators were investigating.
