LAS VEGAS, March 23 /PRNewswire-FirstCall/ — MGM MIRAGE (NYSE:MGG) and Mandalay Resort Group (NYSE:MBG) today jointly announced that they have entered into a definitive agreement with an affiliate of Marian Ilitch to sell Mandalay’s indirect 53.53% interest in the MotorCity Casino to Mrs. Ilitch’s affiliate. Mrs. Ilitch, through affiliates, currently owns a 25% interest in the casino.
