In his first season at stud, Spearmint covered a Galopin mare owned by Alfred Cox called Galicia. This produced a filly called Silesia. Great expectations were held for her due to the performances of her older half-brothers, Bayardo and Lemberg. Bayardo was to win seven stakes races from the 6 furlongs (1200m) of the Middle Park Stakes to the 20 furlong (4000m) Ascot Gold Cup. Lemberg may have been the superior runner winning nine stakes races in total including the Epsom Derby. She was unplaced as a juvenile against only the best company, and as a 3yo was second in both the Knowlsley Dinner Stakes and Newmarket Oaks. Only three runners though lined up for both races. In all at that age, she was placed three times in eight starts.
At stud, Silasia was to excel, and her daughter by Beppo in My Dear won the Dewhurst Stakes at two and the Oaks Stakes and Champion Stakes at three. My Dear also ran second in the Two Thousand Guineas and the St Leger. At stud she produced a son by Cicero called Caravel who was purchased by Harry Taylor of Wellington Stud in NSW. Mr Taylor paid. £15,000 for Caravel, which was reportedly the most expensive Australian bloodstock purchase ever
