Duntle is working towards a return to action, which could come at the Irish Guineas meeting at the Curragh next month.
The David Wachman-trained daughter of Danehill Dancer progressed at a rate of knots last season, winning a maiden on the Polytrack at Dundalk on her first outing.
She then triumphed at Royal Ascot in the Sandringham Stakes and followed up in the Group Three Desmond Stakes.
And the Niarchos family-owned filly looked to have made the leap to Group One company on her final outing, when passing the post in front of Sir Henry Cecil's Chachamaidee in the Matron Stakes back at Leopardstown.
But there was interference in the closing stages, with the officials reversing placings in the stewards' room.
Wachman said: "She is back with us and doing well.
"There's a few Group Threes in May, including around Irish Guineas weekend (Abu Dhabi Stakes, May 25).
"We will start her off and see how we get on.
"She's well suited by a mile."
