Mineshaft, 2003&rsquo;s Horse of the Year and champion older horse, underwent colic surgery Thursday night, according to the farm that stands him, and is expected to make a full recovery.\r\nLane&rsquo;s End Farm in Versailles, Ky., said in a press release Friday afternoon that Mineshaft was &ldquo;bright and alert&rdquo; Friday after undergoing surgery to treat a bowel obstruction. According to the farm statement, the 12-year-old A. P. Indy stallion suffered no blood loss to his intestine.\r\n&ldquo;We are pleased with how Mineshaft is progressing and would hope that he will return to service during the month of April,&rdquo; Lane&rsquo;s End owner Will Farish said. &ldquo;Any breeder needing to discuss their breeding plans can call Lane&rsquo;s End at any time.&rdquo;\r\nMineshaft is the sire of Dubai World Cup hopeful and graded winner Fly Down, Grade 1 winner Discreetly Mine, and other graded winners such as Cool Coal Man, Casino Drive, and Redding Colliery. He stands alongside his sire at Lane&rsquo;s End for an advertised 2011 stud fee of $25,000.\r\nMineshaft is out of the Grade 1-winning Mr. Prospector mare Prospectors Delite, 2003&rsquo;s Broodmare of the Year.
