About 8000 tonnes of ore was removed from a northwest Queensland mine during the search for the body of a worker reported missing last month.

The body of a miner who died while working underground at a Queensland mine last month has been found following a massive search.

Brett Kelly, 34, was last seen on June 18 at Glencore’s copper mine at Mount Isa in the state’s northwest.

It is believed he fell down an ore mine shaft which is one kilometre underground and contains about 100,000 tonnes of ore.

After an initial search failed to find Mr Kelly, specialist machinery was brought in to remove 8000 tonnes of ore from the shaft.

Search teams, including police forensic officers, mine staff and inspectors, worked in shifts around the clock from June 30 until Mr Kelly’s body was found during the early hours of Tuesday.

Investigations are continuing and a report has been sent to the Coroner.
