Up to 60 gardai are searching a woodland in East Cork for missing woman Tina Satchwell.

The intensive search is being carried out after garda received a "key piece of information" regarding the 45-year-old's disappearance.

Satchwell’s husband Richard told 3News Ireland that he is “shocked” that the woodland has become integral to the investigation.

The heartbroken man told the outlet he is still “hoping that Tina (above) is out there and she’s going to get in touch”.

Satchwell has been missing from her home in Youghal since March 2017. She was last seen by her husband before he left home to go shopping.

Mitchel’s Wood at Bridgetown near Castlemartyr is now the subject of a major search operation that could take up to three weeks.

"I'm hoping that Tina is out there and she's going to get in touch," he told 3News. 

"I don't want to even go down the road of thinking the other way because I won't be able to cope. I feel sick. I've been in touch with Tina's family and they're the same way."

"The worry is always there," he said when asked about the possibility her body may be found, but denied he had any involvement in her disappearance.

"I could never harm my wife. Never. Everybody who knows us knows that," he said.

"My wife is there somewhere and I do believe she's going to turn up and it will all be put to bed."
