Casino magnate Steve Wynn continued to hit a gold mine in Macau after his gambling facilities in the former Portuguese enclave helped Wynn Resorts Ltd. triple its profit in the fourth quarter of 2017.

In a regulatory filing on Monday, Wynn announced that its net revenues jumped 29.9 percent to $1.69 billion in the last three months of 2017 compared to $1.30 billion recorded in the same period in 2016.

Shares of Wynn Resorts and other casino giants such as Las Vegas Sands (LVS) rallied after the announcement, hitting multi-year highs.

The casino operator attributed the better-than-expected results to the performance of Wynn Macau and Wynn Palace, which partially offset the lackluster performance of Wynn’s Las Vegas operations.
