April 9 (Bloomberg) -- Colony Capital LLC and Crown Ltd. have ended investment talks with MGM Mirage, the Wall Street Journal reported, citing unidentified people familiar with the situation.

Colony and Crown had been considering a joint investment in the casino company controlled by investor Kirk Kerkorian, the newspaper said. MGM now may be concentrating on negotiating a deal with lenders, the Journal said.

MGM Mirage was talking with Colony to obtain as much as $750 million in secured loans in an effort to refinance MGM’s debt, two people with knowledge of the discussions told Bloomberg News on April 6. MGM Mirage seeks to formulate a plan to fund CityCenter by April 13, when lending waivers for the multibillion-dollar development expire.

Alan Feldman, a spokesman for MGM Mirage, said the company continues to hold talks with investors and declined to identify them, the newspaper said.

Geoff Kleeman, a spokesman for Melbourne-based Crown, didn’t return voice-mail messages left by Bloomberg on his office and cell phone outside of business hours.
