HONG KONG, May 19 (Reuters) - Galaxy Entertainment Group, a top casino operator in the gambling enclave of Macau, is considering taking on more debt to fund new phases of its HK$10 billion ($1.9 billion) Macau mega-casino project.

The company has already raised about HK$6 billion for the project through previous financing, and is leaning towards a similar strategy for upcoming phases, Chief Financial Officer Bob Drake told Reuters in an interview on Tuesday.

He declined to be more specific, but said Galaxy would make a more definite decision in the later part of the year, after seeing how Macau's newest mega-casino, built by Melco-Crown Entertainment Ltd, performs after its June 1 opening.

Drake added he is cautiously optimistic about a recovery in Macau's gaming sector, which has seen revenue fall in the last two months during the global downturn after years of explosive growth.

"We're seeing a lot of positive indicators, but I'm not sure whether we have a trend," he said.
