AN estimated $1 million-plus worth of trailer went up in flames after a suspected arson attack outside a Central Queensland mine late on Saturday night.
Police are appealing for information after two Drake low-loaders were extensively damaged by fire after they were parked near the entrance to Blackwater's Curragh mine.
And in a busy weekend for police at Blackwater, officers are also investigating the theft of $40,269 from the Capricorn Hotel.
The money, which was predominantly in $20 notes, was taken from a safe between 11am Sunday and yesterday.
The trailer fires occurred after 11pm Saturday, with the vehicles sitting on the corner of the Blackwater-Cooroorah and Curragh mine access roads. One of the trailers was loaded on top of the other.
They were destined for Rockhampton so work could be undertaken on one of the machines which had a mechanical problem.
"All fires are treated as suspicious," the Central region's top detective, Inspector Cal Lynch, said yesterday.
Blackwater police CIB officer-in-charge Detective Sergeant James O'Keeffe said it was not known whether the fire was the result of arson.
It's understood workers at the mine were the first to raise the alarm after seeing smoke in the area.
Both vehicles were badly damaged and remained on site yesterday as scientific officers continued with a further examination.
Det Sgt O'Keeffe said he was led to believe the low-loaders, 2008 models, were worth more than $1 million.
Investigations into both incidents are continuing. Anyone with information should call Crime Stoppers on 1800 333 000 or Blackwater police on 4982 5933.
