The Nevada Gaming Control Board last month approved a license for the M Resort, scheduled to open in March in Las Vegas. Owner Anthony Marnell III said the proposed 1 million-square-foot retail complex has been delayed by two years. The Nevada Gaming Commission still must give approval for the property. The board also approved the purchase of Cannery Resorts by Australia’s Crown Casino. The deal still is contingent on approval by Pennsylvania regulators, where Cannery operates the Meadows racino near Pittsburgh.
