Isotope to be Sold at Magic Millions Broodmare Sale

Stakes-winning Deep Field mare Isotope, a breeding prospect with an ever-improving international pedigree, will be offered at the Magic Millions National Broodmare Sale, by her owners headed by Black Soil Bloodstock.

Isotope, who was a AU$170,000 (US$122,145) purchase from the 2019 Magic Millions Yearling Sale by Black Soil Bloodstock's Brian Siemsen, trainer Tony Gollan, and agent John Foote, returned AU$1.26 million ($925,207) in prize-money from 19 starts, winning six races, three of them at listed level.

Arguably unlucky in a number of starts during her career, most notably when losing the rider when a short-priced favorite in the AU$2 million Magic Millions 3YO Guineas, she was also placed twice at group 2 level and ran fourth in a Stradbroke Handicap (G1).

Isotope's dam Great Dansaar is a half sister to Yankee Rose, the Australian group 1 winner who is making a huge impact as a broodmare in Japan, producing brilliant dual grade 1-winning filly Liberty Island, who stunned her rivals and the racing public with her victorious display in the Oka Sho (G1) last Sunday.

"I would say there would be interest to a level (from Japanese buyers)," Black Soil Bloodstock principal agent Harry McAlpine told ANZ Bloodstock News.

A banner mare for Black Soil Bloodstock, Isotope punished her rivals on debut in a Doomben 2-year-old maiden by 10 lengths before going on to beat 12 group 1 winners across her career, and contest against some of Australia's premier Thoroughbreds. 

"She was a precocious 2-year-old. She won her debut by 10 lengths and went on to split Rothfire and Wild Ruler in the Champagne (Classic, G2)," McAlpine said.

"That Arrowfield Stakes (G2) (second placing) where Wild Ruler beat her, she was in front a bound before and a bound after the post. That race you could say should be a group 1 given the graduates to come out of it. 

"She actually beat home 12 individual group 1 winners across her 19 starts—she was very much contesting with the elite for the entirety of her racing career."

Isotope's juvenile half sister Mighty, who is trained by Gollan and raced by Black Soil Bloodstock, Brae Sokolski, and Ozzie Kheir, is back in work after winning one of her two starts prior to Christmas.

"With Isotope being sold, it's great that we still have a hold on the family with the promising 2-year-old coming through, so it would be nice to see her reach stakes level," McAlpine said.

With Magic Millions close to finalizing the catalog for next month's National Broodmare Sale, managing director Barry Bowditch was delighted that rising 6-year-old Isotope will go under the hammer at the Gold Coast. 

"Isotope is an outstanding prospect. Her race record represents her quality and I don't think we got to the bottom of her on the racetrack and when you look at her pedigree, it's becoming an international pedigree, a very commercial pedigree here in Australia. I think of all the stakes-winning mares in our catalog, she is one of the major highlights," Bowditch told ANZ Bloodstock News.

Isotope joins four-time New Zealand group 1 winner Levante, Forbidden Love, Snapdancer, and Coventina Bay as high-class mares who will be offered through the Magic Millions sale from May 23-25.
