Just a head and a neck separated the 16-1 winner from Anna Salai and Music Show and she could now run in the Coronation Stakes on 18 June.
Trainer Weld said: "She is tough, genuine and a very progressive filly and has battled her way forward. I need to talk to Angus Gold, Sheikh Hamdan's racing manager, and Sheikh Hamdan himself and we'll make a plan.
"But she might go 10 furlongs next as I don't see her just limited to a mile."
Meanwhile, Aidan O'Brien strengthened his grip on this year's Investec Derby after Jan Vermeer provided him with a 10th victory in the Gallinule Stakes at the Curragh yesterday.
The colt is 5-1 with Ladbrokes for the Epsom Classic on 5 June after his near two-length victory. O'Brien said: "We have Cape Blanco, St Nicholas Abbey, Midas Touch and this one and in an ideal world we'd like to divide them between Epsom and France."
