Search to continue for missing SA teen

A search for a missing teenager, who fled from police more than a month ago after a high-speed car chase on South Australia's Eyre Peninsula, is set to continue.

About 50 local police, mounted officers and volunteers will continue scouring an area of remote scrub west of Whyalla on Thursday in the hunt for Scott Redman.

Police believe the 19-year-old was in a car that was involved in a pursuit on the Eyre Highway near Kimba on April 21.

The pursuit was terminated due to safety concerns, with the black station wagon found on a dirt road 40km east of Kimba four days later.

Inspector Mark Hubbard says the terrain is challenging, with heavy bush in some patches, but police are preparing to cover up to 10 square kilometres.

He says it appears Mr Redman told friends and family he intended to travel to Western Australia but there's no clear information on his location and fears are growing for his wellbeing.
