Police have thrown huge resources behind the search for a teenager who was last seen six days ago in the northwest Queensland city of Mount Isa.

More than 80 people have spent almost a week desperately searching for a northwest Queensland teen whose disappearance has baffled police.

Kyle Coleman, 17, was last seen at a house in the Soldiers Hill area of Mount Isa about 6am (AEST) on Saturday.

It’s believed he’d earlier attended a party and was intending to walk the three kilometres from Soldiers Hill to his Parkside home, but he never arrived.

On Wednesday, police found the body of Kyle’s 21-year-old friend, who’d been involved in the search for the teenager.

Police have said the death is not considered suspicious.

The man is thought to be the last person to see Kyle and the pair had visited a property near Camooweal, west of Mount Isa, the day before Kyle disappeared.

Mount Isa Inspector Trevor Kidd says there is no evidence to suggest the case is a murder-suicide.

“There’s no information or evidence to suggest there’s anything untoward but we’ve got very extensive investigations going on,” he told AAP.

Insp Kidd says police are baffled by Kyle’s disappearance and are urging anyone with information to come forward.

“That’s the bottom line – we need people to come forward,” he said.

“The reality is it’s nearly been a week – but there’s always hope.”

Kyle’s parents Rob and Sonia Coleman say they’re desperate for news of their son.

“Somebody has got to have seen something – kids just don’t go missing out of the blue,” Mr Coleman told the ABC on Friday.

Mrs Coleman is clinging to hope her son is ok.

“Kyle if you can come home, come home – if you can’t, we’re going to get you,” she said.

Police have thrown huge resources behind the search for Kyle, a popular young man who enjoys the outdoors.

More than 20 police officers, including investigators from Cairns, Brisbane and Townsville, along with 60 locals have joined the search.

Eight helicopters spent Friday searching a large area in and around the Camooweal property Kyle and his friend visited last Friday.

Insp Kidd says no new information has come to light and police are looking over areas they’ve focused on over the past week.

Kyle’s disappearance has had a “massive” impact on the Mount Isa community with many locals taking days off work to join the search, Insp Kidd says.

The search will continue on Saturday.

Kyle was last seen wearing a black T-shirt with a white motif, a white flat Obey cap, a pair of light coloured shorts and skate shoes.

He is Caucasian with sandy coloured short hair, hazel eyes, of a slim build and approximately 173cm tall. He may have been carrying a green sleeping swag and backpack.
