Caley Day said the trail for Mr Day, 54, who went missing after leaving his home in Peak Hill in January last year has gone cold.

“I am not sure what else to do anymore,” Ms Day said this week.

“We are just desperate to know that he is okay.”

Caley hopes that putting Mr Day’s face “back out there” might generate new leads to his whereabouts.

An extensive search for Mr Day took place near Gooloogong last year as he had previously lived in the area.

He was last seen at a truck stop on the Newell Highway about 10 kilometres north of Parkes on Sunday, February 5, 2017.

His vehicle – a green 2000 Ford Fairmont – was left parked in a car park on Rankin Street, Forbes, between Monday, January 9, 2017 and Wednesday, January 25, 2017.

Detectives pieced together the days leading up to his disappearance and determined Mr Day was picked up hitch-hiking at an address in Forbes and dropped at the Gooloogong Caravan Park on Wednesday, January 25, 2017.

Police have conducted an extensive search of a property in Gooloogong owned by his family and it’s possible he may have stayed at this location for a short period of time; however, he was not located.

No transactions have been made from Mr Day’s accounts since his disappearance.

Police are urging anyone in the community who may have information on Mr Day’s whereabouts, or any other information about his disappearance, to come forward.

He is described as being of Caucasian appearance with an olive complexion, about 175 centimetres tall, of a medium build, with grey short hair and hazel/brown eyes.

He may be wearing blue jeans, a beige top, work boots and a dark-coloured Akubra hat.

Anyone with information about his whereabouts is urged to call Crime Stoppers on 1800 333 000 or through www1.police.nsw.gov.au/

Information you provide will be treated in the strictest of confidence.
