Cartimandua will make the trek across the Irish Sea to tackle Pattern company in the Ballyogan Stakes at Leopardstown next month.
The lightly-raced filly continued her progression of 2007 when reappearing with another taking win in Listed company at Nottingham on Saturday.
Trainer Ed McMahon has been delighted with her progress and was not unduly surprised to see her land the hat-trick with something in hand at the weekend.
"She's very well and seems to have come out of her race well, so we're very pleased with her," said the Staffordshire-based handler.
"She's looking forward to going to Leopardstown next for a Group Three sprint on June 4.
"Even as a three-year-old she won a fillies' Listed race against older horses - the Cecil Frail - and I always have held her in very high regard.
"I also ran her first time out as a two-year-old in a Class 3 maiden at Newmarket's July course.
"I thought so much of her I was happy to take on the big boys and now she's proving me right."
