The five-year-old has been a real money-spinner since moving to Lyons from Richard Fahey, winning five times for the Meath trainer, including most recently a Listed contest at Kempton.
Lyons said: “She holds all the entries in the early closing Group Threes that we have, like the Amethyst Stakes at Leopardstown, all the way up to the Ballycorus Stakes.
“She’ll also have an entry in the Windsor Forest at Royal Ascot, but it is all ground dependant – she wants good ground and will be running in Group Threes from seven furlongs to a mile.
“The aim is to win a Group Three with her and we’ll take it from there.
“I’m delighted with her at the moment, she has come back well from Kempton. She is very professional and is already back to her normal weight.
“She won’t be running in the ground we have at the moment, there’s no Group race in Dundalk for her so it is down to summer ground.
“You’d hope we will get better ground at Ascot, but the Windsor Forest is a Group Two and I’d like to win a Group Three before going that route.
“There’s the Athasi Stakes at the Curragh on May 6 and the Amethyst at Leopardstown on May 12. There’s also a race in Lingfield (Chartwell Fillies’ Stakes) on May 11.
“She has all these options and ideally we will stick to fillies’ races.”
Duntle meanwhile 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 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.”
