UPDATED: ONE of SA's most iconic stations, Collinsville, via Mount Bryan (pictured), remains unsold after being passed in at auction on Thursday.
Bidding started at $2.8 million then stalled at $3m.
A vendor bid at $4.5m was then called out three times with no sale.
Selling agent and Ray White Clare Valley director Geoff Schell said the Collinsville, Mallett, Willara and Ketchowla stations would continue to be offered as a whole, but there had also been strong interest in individual properties.
Altogether the holding comprises 56,094 hectares of land.
Mr Schell said earlier this week that there had been "in excess" of 40 enquiries for the property.
He expected sale negotiations to continue "strongly" for the next 48-hours.
The property was taken up by John Collins in the 1880s and has only had three owners.
Current proprietors Paddy and Helen Handbury bought the property, home to the famous Collinsville Merino Stud, in 1994.
Last month, Collinsville manager Peter Whittlesea said the stud's operations – which would be retained by the Handburys – remained unaffected, with the stud flocks largely run on other land. They continued to be committed to the sheep and wool industry.
Mr Whittlesea said the company was offering Collinsville plus Mallett, Willara and Ketchowla stations to restructure its pastoral interests.
"They are very productive stations and offer a once-in-a-lifetime opportunity for someone to buy good station country close to Adelaide," he said.
The pastoral holding has an estimated carrying capacity of 15,000DSE.
