Police will search several spots in the Blue Mountains for the remains of a woman who disappeared more than 14 years ago.

Belinda Peisley was 19 when she was last seen at her home in Katoomba in September 1998.

Police have renewed their appeal for the mother of two as specialist police prepare to search a number of locations in Blackheath from 9am (AEDT) on Friday.

The mother vanished when her sons were just one and three years old.

Police have said Ms Peisley, who had drug problems and debt, had received a considerable inheritance prior to her death.

The inheritance had resulted in many visitors to her home.

A coronial inquest into her disappearance is set to resume at Katoomba Local Court next week.

Police and members of Ms Peisley's family will address the media later on Friday.
