Coronial investigation is underway after a worker died at a Northern Territory mine site The recovery of the body was significantly delayed by ongoing safety concerns

The recovery of the body was significantly delayed by ongoing safety concerns NT Minister said the government was working to implement industrial manslaughter laws and had investigated other incidents

NT Police released a statement on Wednesday afternoon, saying Bootu Creek mine employee Craig Butler had been found at the site, 110 kilometres north of Tennant Creek.

"Our sincere condolences to the family, friends and colleagues of Mr Butler," a spokesperson said.

"We thank everyone involved in the recovery."

The collapse that killed Mr Butler was first reported on 2:40pm on August 24.

NT Police Superintendent Chris Board said at the time the man's chances of survival were low.

All in-pit mining activity was ceased after the incident but ore processing at the plant has continued.

Coronial investigation underway into death

Efforts to find Mr Butler were hampered due to ongoing safety concerns at the site.

The NT Police spokesperson said, as there was a coronial investigation underway, there would be no further comment.

Primary Industry and Resources Minister Paul Kirby said on Tuesday the operation to recover Mr Butler had been "intricate and extensive".

Mr Kirby said he had visited Bootu Creek mine and heard concerns about mine safety and previous incidents.

"We were aware in our department of a number of different incidents, or slips as they're termed within the industry, on the site," he said.

"Any slips like that would be of significant concern to us. From being on the site and having a look at the size of the event that's just happened, it's not a slip, it's more of a collapse.

"I'm not a mining expert, and certainly not a geological expert, but it looks like a massive event, obviously, and any of those events on that site would be a concern to us."

Mr Kirby said the NT Government would take a strong stand on safety standards if the ongoing investigation found any improper conduct.

"We know that industrial manslaughter laws are being worked on as we speak and that will come back into the Parliament through the course of this year," he said.

"I can absolutely guarantee people that if there has been any breach of the law our Government will take the strongest possible stand that it can."

The mine's owner, Singapore-based OM Holdings Ltd, issued a statement after the recovery operations concluded.

"Mr Butler’s body has been provided to authorities and will be returned to his family as soon as possible. The Company is continuing to support the family and colleagues of Mr Butler during this difficult time," it reads.

"The Company deeply regrets the loss of Mr Butler’s life. Employee safety is a priority for the Company."
